If you are sourcing a straight boom crane — the telescopic, non-articulating type mounted on a truck chassis — the shortlist almost always comes down to a handful of established builders, and the right pick depends far more on your lift chart and duty cycle than on brand name alone. In China, the straight boom crane market is dominated by a small group of hydraulic crane specialists and integrated truck manufacturers who either build their own booms or partner with established crane makers. This article explains how to evaluate them, what separates a good supplier from a risky one, and how to match a crane-and-chassis package to real working conditions.
I’ll walk through the selection criteria first, then apply them to the main categories of manufacturers, and finish with the commercial and compliance questions that trip up first-time importers.
What “Straight Boom” Actually Means in a Truck Crane Context
A straight boom crane (also called a telescopic boom crane) extends in a straight line from the pedestal. An articulating crane folds at a knuckle. Both are mounted behind the cab or at the rear of a flatbed or cargo chassis, and both are used for loading, unloading, and short-radius lifting.
The distinction matters because the two types have different load charts, different stowed dimensions, and different maintenance profiles. A straight boom generally gives you longer horizontal reach for the same number of boom sections, and it is easier to operate for repetitive lifts at a fixed radius. An articulating crane is more flexible in tight spaces and can reach behind obstacles. If your work is mostly loading pipes, steel, or precast elements onto a flatbed, the straight boom is usually the better fit.
What buyers consistently get wrong is treating the nominal tonnage — “8-ton crane,” “12-ton crane” — as the lifting capacity. It is not. It is the maximum capacity at the shortest radius with the boom fully retracted and the outriggers fully deployed. At full extension, the same crane may lift a fraction of that figure. The load chart is the only document that tells you what the crane can actually do.
How to Evaluate a Straight Boom Crane Manufacturer
There is no single “best” manufacturer, because the right supplier depends on your application, your budget, and how much engineering support you need. What you can do is apply a consistent set of criteria and see which suppliers meet them.
1. Crane and chassis integration capability
A truck-mounted crane is not a crane bolted onto a truck. The mounting position, subframe design, outrigger spread, and reinforcement of the chassis frame all affect stability and axle loading. A manufacturer that only assembles cranes onto chassis without engineering the interface will produce a vehicle that is either unstable at full reach or overloaded on one axle.
Ask how the subframe is designed, whether the chassis frame is reinforced, and how the outrigger loads are distributed. A supplier that can answer this in engineering terms — not marketing terms — is worth a second conversation.
2. Load chart transparency
A serious manufacturer publishes full load charts: capacity at each radius, at each boom length, with and without outriggers. If a supplier only quotes a single tonnage figure and cannot produce a chart, that is a warning sign. You need the chart to confirm the crane will lift your heaviest load at your longest required radius.
3. Remaining payload after crane installation
The crane itself has weight — often several tonnes including the subframe and outriggers. That weight comes directly out of your cargo payload. A 12-ton crane on a 4×2 chassis may leave very little legal payload for the cargo you actually want to carry. This is a classic trade-off: bigger crane, less cargo. The right choice depends on whether you lift more than you carry, or carry more than you lift.
4. Chassis compatibility and axle loading
The crane mounting position shifts weight onto the rear axle (or front, depending on placement). You need to confirm the front and rear axle loads stay within the chassis rating and within the destination country’s legal axle limits. A crane that is technically fine but pushes you over the legal rear axle limit in your market is not a usable configuration.
5. Parts availability and service support
Hydraulic pumps, cylinders, seals, control valves, and PTO components are the parts that fail. If the manufacturer uses proprietary components with no export spares program, a single seal failure can idle the truck for weeks. Ask what spare parts are recommended for the first year, and whether the supplier stocks them for export orders.
6. Documentation and export experience
For international buyers, the manufacturer’s ability to provide correct export documentation, shipping coordination, and pre-shipment inspection matters as much as the crane itself. A supplier with no export track record will create problems at the port, not at the factory.
Categories of Straight Boom Crane Manufacturers
The market breaks into three broad groups. Each has a different strength profile.
| Manufacturer type | Typical strength | Typical limitation | Best fit |
|---|---|---|---|
| Dedicated hydraulic crane specialists | Deep crane engineering, extensive load charts, mature hydraulic design | May not control chassis supply; integration depends on partner | Buyers who prioritize crane performance and can specify chassis separately |
| Integrated truck manufacturers with in-house crane divisions | Single-source chassis + crane + body, consistent warranty, simpler logistics | Crane range may be narrower; less specialization at the top end | Fleet buyers who want one supplier and one warranty |
| Upfitters and assemblers | Flexible configurations, can mix crane brands and chassis | Engineering depth varies widely; quality depends on the individual shop | Buyers with a specific crane brand requirement or unusual chassis |
Chinese manufacturers in all three categories have improved significantly in hydraulic reliability and load chart discipline over the past decade. The gap that remains is usually in documentation, export support, and after-sales parts logistics — not in the basic hydraulic hardware.

Selection Criteria in Practice: A Framework
Rather than ranking manufacturers by reputation — which is hard to verify and varies by application — use this framework to shortlist suppliers.
Step 1: Define the lift requirement precisely
- Maximum load weight (not nominal crane tonnage)
- Horizontal working radius at which that load must be lifted
- Lifting height required
- Whether outriggers can be fully deployed at every job site
- Frequency of lifts per day
Step 2: Define the cargo requirement
- Cargo type and density
- Required cargo payload after crane weight is deducted
- Body or bed configuration (flatbed, dropside, stake)
- Loading and unloading method
Step 3: Define the operating environment
- Road condition and gradient
- Daily mileage and operating hours
- Climate and altitude
- Whether the truck works in urban, construction, or remote sites
Step 4: Define the commercial and compliance frame
- Destination country and port
- Emission standard required
- Steering side (LHD or RHD)
- Axle weight and dimension limits
- Registration and homologation requirements
- Budget range and financing
- Quantity and delivery timeline
Once these are written down, you can send the same specification to multiple suppliers and compare their proposals on equal terms. That is far more reliable than comparing brand names.
Why Chinese Truck Factory Fits This Framework
Chinese Truck Factory operates as a single-source supplier for truck-mounted crane packages, combining chassis selection, crane integration, and export coordination. For buyers applying the framework above, that means one point of contact for specification, one warranty scope, and one shipping arrangement.
The practical advantages are:
- Configuration flexibility. Crane tonnage, boom length, mounting position, and chassis can be matched to the lift and cargo requirements rather than forced into a fixed catalog model.
- Export documentation and shipping support. The company handles the export side, which reduces the coordination burden on buyers who do not have a local import agent.
- Spare parts planning. Recommended spares packages can be included with the order, which matters for buyers in markets where hydraulic components are not locally stocked.
- Direct communication with engineering. Load chart questions, axle loading concerns, and mounting position decisions can be addressed before the order is placed.
Buyers evaluating lifting capacity should compare the actual load chart before selecting a truck-mounted crane, and should confirm how the crane weight affects remaining cargo payload on the chosen chassis.

The Load Chart Is the Specification
I want to emphasize this because it is the single most common source of disappointment in crane truck purchases. The nominal tonnage is a marketing number. The load chart is the engineering document.
A typical straight boom load chart shows capacity dropping as radius increases and as boom length increases. For example, a crane rated at 10 tonnes might lift:
- 10 tonnes at 2.5 m radius, boom retracted
- 4 tonnes at 8 m radius, boom partially extended
- 1.5 tonnes at 15 m radius, boom fully extended
These figures are illustrative only — actual values depend on the specific crane model, outrigger configuration, and whether the lift is over the rear or the side. The point is that the same crane covers a wide range of capacities, and you must match the chart to your actual lift.
When requesting quotations, ask for the load chart for the exact crane model proposed. Compare it against your maximum load at your maximum radius. If the chart does not cover your requirement, the crane is the wrong size regardless of what the nominal tonnage says.
Chassis and Axle Loading: The Hidden Constraint
The crane, subframe, outriggers, and hydraulic system add significant weight. On a typical 4×2 or 6×4 chassis, this can be several tonnes. That weight affects:
- Remaining legal payload for cargo
- Front and rear axle load distribution
- Stability during lifting
- Braking performance
- Fuel consumption
The mounting position is a design decision, not a fixed feature. Mounting the crane behind the cab shifts weight forward; mounting it at the rear shifts weight backward. Each position has implications for axle loading and for how much cargo bed length remains usable.
Before finalizing a configuration, ask the supplier to provide estimated front and rear axle loads with the crane installed and with a representative cargo load. Then compare those figures against the chassis ratings and your destination country’s legal axle limits. If the numbers do not work, the configuration needs to change — either a lighter crane, a longer wheelbase, or a higher-capacity chassis.
Hydraulic System and PTO: Where Reliability Is Won or Lost
The crane’s hydraulic system is driven by a power take-off (PTO) from the truck transmission. The PTO engagement method, pump type, oil cooling, and filtration all affect reliability.
Key points to confirm:
- PTO type and engagement mechanism (mechanical, pneumatic, or hydraulic)
- Pump displacement and whether it matches the crane’s flow requirement
- Hydraulic oil cooling — especially important in hot climates and continuous-duty applications
- Filtration level and service interval
- Hose routing and protection from abrasion and heat
Hydraulic oil overheating is a common cause of slow crane operation and seal failure. If the crane will run continuously through a shift, confirm the cooling capacity is adequate for the ambient temperature in your market.
For buyers also considering other specialized vehicles, the same integration principles apply across specialized vehicles — the superstructure and the chassis must be engineered as one system.

Maintenance Planning for Straight Boom Cranes
Downtime usually costs more than the repair itself. A crane truck that is idle because a seal failed or a hose burst is not earning. Maintenance planning should focus on preventing those failures.
Daily checks
- Hydraulic oil level and visible leaks
- Hose condition — cracks, abrasion, wet spots at fittings
- Outrigger operation and pad condition
- Crane controls and emergency stop function
- Tire condition and pressure
- Lights and warning devices
Periodic checks
- Hydraulic oil condition and filter replacement
- Pump and PTO drive components
- Cylinder rod condition and seal integrity
- Boom wear pads and sliding surfaces
- Structural inspection of the subframe and mounting bolts
- Load chart verification and safety decal condition
Exact service intervals should follow the crane manufacturer’s manual and the chassis manufacturer’s schedule. Do not assume intervals from one brand apply to another.
Common fault diagnosis
If the crane lifts slowly or loses capacity, work through the system in order rather than replacing parts at random:
- Check hydraulic oil level and temperature
- Check filter restriction
- Check pump output pressure
- Check PTO engagement and drive
- Check control valve operation
- Check cylinder internal leakage
- Check for hose restriction or kinking
- Confirm the load is within the chart for the current radius
Overloading is a frequent cause of apparent “loss of power.” If the load exceeds the chart at that radius, the crane will not lift it — and forcing it will damage the system.
Total Cost of Ownership for a Crane Truck
Purchase price is only the first number. The full cost picture includes:
| Cost element | What drives it |
|---|---|
| Purchase price | Crane tonnage, boom length, chassis brand, emission standard, options |
| Freight and insurance | Shipping method (RoRo, breakbulk, flat rack), route, destination port |
| Import duties and taxes | Destination country tariff schedule and vehicle classification |
| Compliance and registration | Homologation, inspection, modification if required |
| Fuel | Gross weight, route, idling, driver behavior, axle ratio |
| Tires | Axle load, road surface, tire specification |
| Scheduled maintenance | Oil, filters, hydraulic service, lubrication |
| Unscheduled repairs | Hydraulic components, seals, hoses, structural repairs |
| Downtime | Parts availability, service capability, crane complexity |
| Residual value | Brand recognition, condition, market demand |
Two configurations with the same purchase price can have very different five-year costs. A cheaper crane with poor parts support can cost more in downtime than a more expensive crane with a stocked spares program. When comparing quotes, ask each supplier what spares they recommend for the first year and what the lead time is for critical hydraulic components.
Buyers who also operate other heavy equipment may find the same TCO logic useful when evaluating heavy-duty construction vehicle solutions, where duty cycle and maintenance access often dominate the cost equation.
Compliance and Destination-Market Checks
There is no such thing as a “globally compliant” crane truck. Requirements vary by country and change over time. Before ordering, confirm:
- Emission standard required for registration
- Vehicle type approval or homologation requirements
- Axle weight and gross vehicle weight limits
- Overall dimensions and turning radius limits
- Steering side (left-hand or right-hand drive)
- Lighting and marking requirements
- Braking system requirements
- Crane safety and inspection requirements
- Operator certification requirements
Do not rely on a supplier’s general statement that a vehicle “meets international standards.” Ask for the specific standard and confirm it against your destination country’s registration authority. If the supplier cannot provide the documentation, budget for a local inspection or modification.
For buyers importing into markets with established regulations, checking the official transport ministry or customs authority website is the most reliable starting point. Requirements are updated periodically, and a configuration that was acceptable two years ago may not be today.
Shipping and Import Considerations
Crane trucks are typically shipped by RoRo (roll-on/roll-off) or breakbulk, because the crane and body make container shipping impractical for most configurations. The choice depends on:
- Vehicle dimensions and weight
- Whether the vehicle can be driven onto the vessel
- Number of units
- Route and destination port
- Whether the crane needs to be partially disassembled for transport
Confirm with the supplier which shipping method they recommend and what the estimated freight cost is. Also confirm the Incoterm — FOB, CFR, or CIF — because the price you compare must be on the same basis. An FOB price and a CIF price are not comparable without adjustment.

What to Include in a Quotation Request
The more precise your inquiry, the more accurate the response. For a straight boom crane truck, include:
- Destination country and port
- Application (construction, steel distribution, precast, general cargo)
- Maximum lift weight and working radius
- Required lifting height
- Cargo type and required payload
- Body or bed configuration
- Daily mileage and operating hours
- Road condition and gradient
- Drive configuration preference (4×2, 6×4, etc.)
- Steering side
- Emission standard
- Quantity
- Required options (outrigger type, remote control, load moment indicator)
With this information, a competent supplier can propose a specific crane and chassis combination and provide the load chart, axle load estimate, and price on a defined Incoterm.

Frequently Asked Questions
How do I choose the right crane tonnage?
Start with the load chart, not the nominal tonnage. Identify your maximum load weight and the horizontal radius at which you need to lift it. Then find a crane whose load chart covers that combination with margin. A crane rated at 12 tonnes may only lift 2 tonnes at your required radius, so the nominal figure alone tells you nothing useful.
What is the difference between a straight boom and an articulating crane?
A straight boom extends in a straight line and generally offers longer horizontal reach for the same number of sections. An articulating crane folds at a knuckle, which gives more flexibility in tight spaces and around obstacles. Straight booms suit repetitive lifts at a fixed radius; articulating cranes suit confined or obstructed work areas.
How much cargo payload do I lose when adding a crane?
The crane, subframe, outriggers, and hydraulic system add weight that comes directly out of cargo payload. The exact figure depends on crane size and mounting position. Ask the supplier for the estimated curb weight with the crane installed, then subtract that from the chassis gross vehicle weight rating to see remaining payload. Confirm the result against your destination country’s legal weight limits.
Which chassis configuration works best for a crane truck?
It depends on the crane weight, cargo payload, and road conditions. A 4×2 chassis suits lighter cranes and lighter cargo. A 6×4 chassis handles heavier crane and cargo combinations and provides better traction on poor roads. An 8×4 may be needed for very heavy crane packages or where higher rear axle capacity is required. The deciding factor is axle loading, not preference.
How do I verify a manufacturer’s load chart is accurate?
Ask for the load chart for the exact crane model and confirm it is issued by the crane manufacturer, not the truck assembler. Cross-check the chart against the crane’s structural and hydraulic ratings. If the chart seems inconsistent with the crane’s physical size or cylinder dimensions, ask for clarification. A supplier that cannot produce a proper chart is a risk.
What spare parts should I order with a crane truck?
At minimum, plan for hydraulic filters, hydraulic oil, seals for the main cylinders, a set of hydraulic hoses for the most exposed runs, PTO components, and control valve service parts. The exact list depends on the crane model and your local parts availability. Ask the supplier for a recommended first-year spares package and confirm lead times for critical components.
How are crane trucks shipped from China?
Most crane trucks ship by RoRo or breakbulk because the crane and body make container shipping impractical. The choice depends on vehicle dimensions, weight, quantity, route, and destination port. Confirm the recommended shipping method and Incoterm with your supplier before comparing prices, because FOB and CIF quotes are not directly comparable.
What compliance requirements should I check before importing?
Confirm the emission standard, homologation or type approval requirements, axle weight and dimension limits, steering side, lighting and braking requirements, and crane inspection requirements for your destination country. Requirements vary and change over time, so verify with the official transport ministry or customs authority rather than relying on general statements from suppliers.
Final Thoughts
The best straight boom crane manufacturer for your operation is the one whose load chart, chassis integration, parts support, and export capability match your actual working conditions. That is a different answer for a steel distributor doing repetitive lifts at a fixed radius than for a construction company working on uneven ground with varying loads.
Before committing, confirm four things: the load chart covers your maximum lift at your maximum radius; the axle loads stay within both chassis ratings and destination legal limits; spare parts are available for the components most likely to fail; and the supplier can provide correct export documentation and shipping coordination.
Buyers who get this wrong usually do so by comparing nominal crane tonnage or purchase price in isolation. The configuration that works is the one that matches the lift requirement, the cargo payload, the road conditions, the legal weight limits, and the maintenance capability you actually have — with the fewest compromises across all of them.
