Lift heavy loads using a lattice-boom crawler crane configured around the actual load, radius, ground support and assembly plan. The buying process should establish lift definition, boom and counterweight, ground support, and travel under load. Use the comparison checkpoints to prepare a consistent quotation request, define installation and acceptance responsibilities, and identify missing accessories or evidence. OEM/ODM is a project-specific feasibility question; request written confirmation of any proposed change and the supporting documentation.
Lift heavy loads using a lattice-boom crawler crane configured around the actual load, radius, ground support and assembly plan. Compare configuration, interfaces and acceptance evidence before requesting an application-specific quotation or OEM/ODM feasibility review. Include engineered ground-support information.

Lift heavy loads using a lattice-boom crawler crane configured around the actual load, radius, ground support and assembly plan.
Define the lift before the crane class
A crawler crane purchase begins with the required lifts, not maximum rated capacity. Provide load mass, rigging allowance, lifting points, working radii and hook heights. Include the path between pick-up and placement positions and any obstructions. A crane able to lift the load close to its tracks may be unsuitable at the required reach. Describe representative demanding lifts so the offered arrangement can be assessed against actual charts.
Compare exact boom and ballast configurations
Lattice boom length, jib arrangement, counterweight, track position and reeving change usable lifting performance. The chart must correspond to the precise configuration proposed for the project. Verify whether quoted accessories include the required hook blocks, jib components and ballast. Where multiple configurations are needed, account for changeover time and available assembly space. Do not combine the largest reach and capacity numbers from different chart conditions into one assumed capability.
Engineer the working ground
Ground pressure is a project condition, not a simple property that makes a crawler crane suitable for every site. Reactions vary with lift direction, load and geometry. The ground assessment must address bearing capacity, settlement, buried structures and slope. Mats or other support arrangements need an engineered design using the crane reactions. Clarify who supplies this information and who approves the working area before the crane arrives.
| Buying checkpoint | Project information |
|---|---|
| Lift definition | Include rigging weight, operating radius and required hook height. |
| Boom and counterweight | Use the chart for the exact boom, jib and ballast configuration. |
| Ground support | Provide bearing capacity, level tolerance and engineered mat design. |
| Travel under load | Confirm whether the planned movement is permitted by the specific chart. |
| Transport and erection | Plan component weights, assembly space and auxiliary crane needs. |
| Lift documentation | Request charts, inspection records, operator training and lift planning support. |
Assess travel and site access separately
A crawler undercarriage supports mobility within a job site, but movement with a suspended load requires the appropriate manufacturer instructions and chart conditions. Do not assume every planned travel route or load orientation is permitted. Check route width, gradient, ground support and overhead clearance. Also examine access for delivery trailers and erection machinery. Site mobility and road transport are separate planning problems with different equipment and logistics requirements.
Include transport and erection resources
Large crawler cranes are commonly moved in components. Obtain shipping dimensions, individual component masses and the proposed packing or trailer plan. Determine the auxiliary lifting equipment and area needed to erect the selected boom and counterweight arrangement. A transport quote without these boundaries can conceal major local costs. Plan storage for unused components and identify the procedure for later reconfiguration if the project lift requirements change.
Require usable charts and service documentation
The handover should identify the machine and supplied components, relevant load charts, inspection records and operating documentation for the destination. Include training for the agreed configuration and arrangements for specialist service. Ask how control-system faults are diagnosed and how replacement parts are identified. For a used machine, component history and condition require separate investigation; a clean exterior photograph cannot establish structural condition or remaining service suitability.
Set customization boundaries around lifting safety
OEM/ODM requests may cover transport organization, auxiliary interfaces, labeling or job-specific integration, but changing structural members, controls or protective functions requires substantial engineering review. Provide the complete lift cases and destination requirements. Any customized alternative needs its own configuration documentation and supporting assessments.

What should your crawler crane RFQ include?
- Lift definition: Include rigging weight, operating radius and required hook height.
- Boom and counterweight: Use the chart for the exact boom, jib and ballast configuration.
- Ground support: Provide bearing capacity, level tolerance and engineered mat design.
- Travel under load: Confirm whether the planned movement is permitted by the specific chart.
- Transport and erection: Plan component weights, assembly space and auxiliary crane needs.
- Lift documentation: Request charts, inspection records, operator training and lift planning support.
- Project location, destination requirements and intended operating environment
- Required drawings, connection information and site responsibility boundaries
- Representative acceptance case, documentation, training and spare-parts scope
- OEM/ODM: proposed branding, interface or design changes; engineering feasibility and evidence required
Need OEM / ODM customization?
Submit branding, packaging, configuration or engineering requirements for this equipment. Include the target market, initial and annual quantities, required changes and acceptance criteria.
Customization feasibility, permitted branding, development responsibilities, minimum quantity, cost and lead time are reviewed for the proposed supplier and configuration before a quotation is confirmed.
Frequently asked questions
Is maximum crawler-crane capacity enough to select a machine?
No. Capacity changes with working radius, boom and jib arrangement, ballast and other chart conditions. Provide the full load including rigging and the required lift geometry. Evaluate the exact offered configuration against the relevant chart rather than a headline class rating.
Can a crawler crane travel with a suspended load?
Only within the conditions permitted for the specific crane, configuration and operation. Ground support, route, load orientation and chart restrictions matter. Have the lift planner review the intended movement using the manufacturer’s instructions instead of assuming that crawler mobility makes it permissible.
What ground information is needed?
Provide geotechnical information, working-area levels, buried-service or void risks and the proposed lift locations. The crane reactions must be matched to an engineered support design. Clarify responsibility for mats, ground approval and monitoring of settlement during the planned lifting operations.
Why should transport be part of the equipment comparison?
Component dimensions, weights and assembly requirements determine trailer needs, access and auxiliary cranes. Two suitable lifting configurations may impose different mobilization costs and site-space demands. Request a componentized transport and erection plan with clear boundaries for local services and lifting resources.
Which documentation should accompany a crawler crane?
Obtain identification of the machine and supplied boom or ballast components, applicable configuration charts, inspection records and operation and maintenance instructions. Include training and service arrangements. For used equipment, investigate history and condition separately rather than treating generic model documentation as condition evidence.
Can a crawler crane be customized for a project?
Some interfaces and logistics arrangements can be reviewed, but structural, control or protective-function changes require a defined engineering process. Submit the actual lift cases and jurisdiction requirements. The supplier must confirm feasibility and documentation responsibilities; branding alone cannot establish lifting suitability.
