The characteristics of 70U
1 main boom with U shaped cross section design, five main boom, the maximum lifting height of 44.6 meters, play the mechanical properties of high strength steel, make the stress distribution more uniform, bending and torsional capacity is improved obviously
2 embedded slide structure before and after the festival, the jib overlapping part of uniform stress, maximum limit reduces the stress concentration, improve the hoisting performance
3 normally closed rotary brake, new rotary buffer valve is equipped with a unique design, to achieve fast start, stop, speed up the smooth buffer stops.
4 H type leg and a fifth leg, can achieve 360 degrees omnibearing rotary operation, each machine runs can be stepless speed regulation, stable work, reliable, simple operation
The 5 leg in the box through the simulation of strengthening design, leg lateral span provides optimal, guarantee the operation stability
6 vehicle optimization in hydraulic system, sensitive and reliable, better micromotion performance, system of overflow loss, high efficiency and energy saving
7 electro-hydraulic proportional control system with pressure compensation, load feedback makes the work speed is not subject to load variation, good stability, the system power loss
8 advanced height limit and vol-off devices, hydraulic buffer valve, to achieve a smooth and steady free slip fretting
9 automatic torque limiter, overload has control function as well as the length and angle sensor function
The 10 planetary gear type main and auxiliary hoisting mechanism can realize low speed heavy load, light load high speed, step and stepless variable speed, greatly enhance the work efficiency
11 spacious interior space, luxury decoration, the open field of vision, steering wheel, seat, pedal, handle all operating device is convenient and flexible, manipulation
12, the streamlined cab, large space, No Hiro, dust noise reduction, large screen liquid crystal display and seismic pressure gauge, always show the lifting operation, ensure the operation safety
