Powerful Lifting Capacity

The 75 ton crawler crane's large chassis design ensures excellent machine performance and stability within 360°rotation. The maximum lifting capacity of boom is 75t; maximum lifting torque is 71tx4m. For the fixed jib, the maximum lifting torque is 6.7tx22m. The rope diameter of main/auxiliary hoisting devices is 20mm and the rated single rope pull of main/auxiliary winch is 7t.

Excellent Operation

The crane's functions including load sensing, ultimate load regulation and electrohydraulic proportional dead slow control make each motion controlled, smooth and stable. Outmost layer line speed of main and auxiliary lifting winches is 120m/min andthat of luffing winch is 100m/min.

Safety and Reliability

Safe Control System

Switch between two operation modes: working and assembly mode. The 75 ton crawler crane features an electronic level gauge, machine-leaving stop action, emergency electrical control, and a complete set of safety and monitoring devices. No need for recalibration, the load moment limiter makes the equipment safer and saves your operating time.

Reliable Function Guarantee

Substantial safety margin in structural design, load sensitive control hydraulic system, hydraulic key components (pumps, valves, motors, and reducers) and advanced technology of renowned brands ensure the crane's stability and reliability. The control system runs well even in extreme weather and region. The sensor is protected against lightning strike, and the entire machine is closed wired to a waterproof / dust-proof protective grade of up to IP65.

High Return & Low Cost
