Large Scale Engineering Cranes

        Large Scale Engineering Cranes use a high-load boom structure and multi-stage hydraulic lifting system for heavy material handling, infrastructure installation, and continuous lifting operations in construction and industrial projects.

High-Tensile Boom Steel

The boom uses HG70 high-strength structural steel with controlled yield strength to improve lifting stability under heavy-load conditions.

Multi-Section Boom Design

Boom sections are formed with polygonal reinforcement structures to reduce deflection during long-radius lifting operations.

Reinforced Turntable Structure

The slewing platform uses thickened bearing support plates to improve rotational stability during continuous lifting cycles.

High-Pressure Hydraulic System

The hydraulic circuit operates with high-pressure piston pumps to maintain stable lifting speed under heavy loads.

Load-Sensing Valve Control

Hydraulic valves automatically adjust oil flow according to lifting resistance to improve movement stability and reduce energy loss.

Dual Cylinder Synchronization

Boom lifting cylinders use synchronized hydraulic control to reduce lifting deviation during large-tonnage operation.

Wide Outrigger Span

Hydraulic outriggers provide larger ground contact areas to improve stability on uneven construction surfaces.

High-Torque Travel System

The drivetrain uses reinforced reduction gear structures to improve low-speed mobility under full machine weight.

Multi-Angle Steering Control

Optimized steering geometry improves maneuverability within narrow engineering sites.

Full Penetration Welding

Critical boom and chassis welds use full penetration welding technology to improve fatigue resistance under repeated load cycles.

Stress Relief Treatment

Main structural components complete heat treatment after welding to reduce residual stress deformation.

Industrial Corrosion Protection

Steel surfaces undergo sandblasting and heavy-duty anti-corrosion coating treatment before final assembly.

CNC Boom Forming

Boom plates are processed with CNC cutting and precision forming equipment to improve dimensional consistency.

Ultrasonic Weld Inspection

Critical structural welds complete ultrasonic flaw detection before assembly.

Hydraulic Pressure Testing

Hydraulic cylinders and pipelines undergo pressure holding inspection before installation.

Load Simulation Verification

Finished cranes complete overload and stability testing before shipment.
