QY20B Truck Crane
QY20B Truck Crane uses self-made truck crane special chassis, with powerful engine and fully-covered decking plate.
Main and auxiliary winches realize low speed with heavy load and high speed with light load, high working efficiency.
4-section telescopic boom of 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 (AML), overload and over-wind cut-out device, etc., greatly improved safety in operation.
Two cabs ergonomically designed conform to ISO standard, fan, heater and air conditioner equipped acc. to requirement. Driver’s cab is left semi-mounted, fitted with damping and adjustable seat. Operator’s cab is right semi-mounted, equipped with LCD monitor for display of crane various motions.
