QY20B-II Truck Crane
QY20B-II Truck Crane uses self-made truck crane special chassis, with covered decking plate,and powerful chassis engine.
Main and auxiliary winch can obtain low speed with heavy load or high speed with light load,improved work efficiency.
4-section telescopic boom with 12-chord all-round boom profile, 1-section side-mounted jib, single cylinder for front support elevating, fully hydraulic drive, and double H-shaped outriggers.
Well-equipped safety devices such as automatic load moment limiter, overload and over-winding cutout device, etc., greatly improved safety in operation.
Two cabs designed ergonomically conform to ISO standard, equipped with fan, heater or optional air conditioner. Driver's cab is left-side semi-mounted,equipped with LCD monitor for display of various crane configuration and operation.

Note:
The data shown in the table are the max.lifting capacity for the crane set up level and firm ground.
The total rated lifting load includes the weight of hook block and slings.
The working radius in the table is actual value including boom deflection under loads. So lifting operation should be performed according to the working radius, and lifting height is for reference.
