The compact arm head and arm tail design, so that the boom lap length reaches the longest, prolong the service life of the crane.
Using the built-in telescopic arm pulley design, the advantage is that the diameter of the pulley is designed as large as possible, improve the telescopic capacity with load, effectively protect the telescopic wire rope, prolong the service life.
Boom head adopting integral structure, greater intensity(Split head design reduces the boom head carrying capacity).
Rotary organizations adopts a low speed high torque rotary motor, by disc springs and friction plate to brake, it will be more stable, reliable, and outputting larger torque. At the same time, absorbing the stronger inertance of crane effectively during the braking process. When rapid braking, the friction plate can absorb large amounts of energy to protect the whole crane steel Structure.
mechanism hydraulic winch relies on disc spring and friction brake, stable and reliable, efficient, low noise, small calorific value; Rely on hydraulic balanced valves balancing weights when falling, greatly improve product reliability.
The crane boom adopts the larger slider design to reduce the lazy arm specific pressure, at the same time to reduce the wearing capacity.
