Product Description

12 Ton Hydraulic Truck Crane Qy12D451 with Factory Price

Freatures for 12 ton Truck crane QY12D451 from China
The lifting, variable amplitude, rotary, telescopic and other mechanisms of the product adopt manual proportional control and
hydraulic drive, which are characterized by light and flexible operation, stable and reliable operation, stepless speed
regulation, etc.
In the hydraulic system, safety valve and balance are provided. Safety devices such as valves, hydraulic locks, brake valves,
etc., to prevent accidents caused by oil passage overload and avoiding oil pipe rupture.
The upper control valve adopts anti-flow saturation technology, and the flow rate is independent of load, ensuring combined action
Stability and synchronization.

The chassis adopts the ZLJ5260JQZD5 semi-driving three-bridge special chassis produced by our company, and the left-side all-metal
flow.
The linear cab is novel and unique in appearance and has good aerodynamic characteristics. The internal control mechanism adopts
humanized design and it is equipped with National IV electronically controlled engine. Its control system uses bus technology and
has engine fault self-diagnosis function.
Six-speed gearbox, 6×4 drive, hydraulic power steering, light and flexible. The crane is also equipped with various safety devices
such as torque limiter and height limit device and complete lighting to ensure safe and reliable operation and easy night operation.
