50 ton China Truck Crane STC500E with Euro V engine for sale
Excellent lifting capacity
5-section boom, using U-section high-strength structural steel boom, the main boom is 45m long, the main boom + jib is 61m long, and the maximum
lifting height is 61.5m;
The maximum lifting moment of the basic boom is 2009kN.m (41t×5m), the maximum lifting moment of the full outrigger is 1082kN.m (6.9t×16m), and the maximum lifting amplitude of the main boom is 38m.
Powerful chassis
Weichai WP9 series high-torque engine, Fast 9-speed high-load torque gearbox, the maximum vehicle speed is 90km/h, and the maximum grade is 47%;
Special rear balance suspension for large tonnage, high bearing capacity and more reliable;
New low front H-shaped movable legs + industry-leading high-strength rectangular section frame, bringing comprehensively improved lifting torsion and bending resistance and operational convenience;
Equipped with 350L large volume fuel tank.
Efficient hydraulic system
Adopt large flow double variable piston pump, sufficient flow but no waste, efficient operation, energy saving and environmental protection;
Using the new intelligent flow distribution main valve, the combined action is time-varying; using the post-valve compensation technology, the flow is distributed on demand, with excellent fretting and controllability, meeting various precise hoisting requirements;
The pressure drop when the elevation angle is large, and the self-weight drop when the elevation angle is small, the flow compensation technology can automatically limit the speed to ensure a uniform and stable drop;
Integrate boost buffering, sequential braking and free-slip technology, and the turning start and stop is soft and stable.
Humanized control system
The control room provides a variety of user-friendly comfort facilities: the new three-dimensional 7-channel air conditioning system, the front air conditioning button, the new membrane switch button, the mobile phone support, the cup holder, the rear storage platform, etc.;
Intelligent power distribution and control: dedicated battery compartment, intelligent distribution and control of vehicle power;
The left and right sides of the chassis are equipped with newly enlarged 300mm inner width pedal stairs and double cast aluminum alloy handrails, making it more comfortable and safe to get on the car;
An inspection staircase is provided on the right side of the turntable to provide a more convenient and efficient maintenance channel for the hoisting and boom;
Optional quick-joint hoisting wire rope, higher rate replacement efficiency, more heavy-duty lanyards, and more uniform force.
