Manufacturing capability behind your crane
Crane manufacture brings together structural fabrication, precision machining, drive components and electrical assembly. Henan Mine Crane operates production facilities for these connected stages, with robotic equipment used alongside operator loading, setup and inspection.
For buyers, the useful question is how the equipment supports the crane being ordered. A standard workshop bridge crane, a wide-span gantry crane and a process crane can require different fabrication routes, inspection points and component arrangements. The agreed technical specification should connect those requirements to the supplied equipment.
Robotic welding for single- and double-girder beams
Dedicated workstations address inner seams in double-girder main beams. Operators load and initially position the workpiece; a hydraulic turning system changes its orientation, and the robot locates and welds the seam. This arrangement gives the welding equipment access to internal joints that are difficult to reach during conventional fabrication.
Single-girder production uses flexible beam lines and inner-seam robotic welding stations. End-carriage welding robots, stiffener assembly stations and turning platforms are also part of the manufacturing equipment range. The combination supports repeatable fabrication steps while retaining operator involvement where setup and product variation require it.
When reviewing a crane order, confirm the required welding and inspection standards, structural details and documentation. The presence of a robotic welding line does not replace the project-specific inspection and acceptance requirements.
Machining and heat treatment for mechanical parts
CNC floor boring and milling machines and gantry machining centers support the manufacture of crane structures and mechanical components. Dedicated facilities also cover wheel forging and rolling, gear production and wheel-and-axle machining.
Heat-treatment equipment includes automated quenching and tempering, annealing furnaces and carburizing furnaces. Different components need different material properties; the material, treatment and inspection requirements should therefore be selected for the part and duty, rather than applied as a generic specification to the complete crane.
Wheels and drive parts
Wheel forging and rolling, gear machining and dedicated wheel-and-axle production equipment.
Dimensional inspection
Coordinate-measuring equipment and machining inspection support checks against the approved part requirements.
Coating, dimensional checks and agreed acceptance
Robotic coating and automatic spray equipment form part of the production facilities. The appropriate surface preparation, coating system and inspection criteria depend on whether the crane will work indoors, outdoors or in a more demanding environment.
Coordinate-measuring equipment supports dimensional checks on suitable components. Other inspections should be defined by the crane design, applicable standards and contract. Buyers can use the manufacturing review to identify which measurements, material records or test reports are needed for their own acceptance process.
What to review before placing an order
Start with the load, span, lifting height, working frequency and installation conditions. Then review the proposed fabrication, component and inspection scope against the actual application. Photographs of factory equipment are useful context; the order documents define what will be supplied.
For a factory visit or technical review, focus on the production stages that matter to your crane. Identify the structural parts, drive assemblies, coating requirements and inspection records you need to review. Confirm any witness inspection or third-party participation before production planning is finalized.

Before your technical review
Are all manufacturing operations fully automatic?
No. Robotic and automated equipment works alongside operators who load, position, set up and inspect products. The production route depends on the crane and component.
Can I use the factory equipment figures to calculate delivery time?
Delivery depends on the agreed design, component selection, order schedule and inspection scope. Confirm the delivery arrangement in the quotation and contract.
What should I send for a manufacturing and technical review?
Send the crane capacity, span, lifting height, application, working frequency and project location. Include runway or building drawings and any required standards or inspection specifications.
