1. 360° Full Rotation

The SQ8 truck mounted crane which is a straight boom crane can achieve 360°full rotation since it employs a worm gear reducer.

2. Excellent Stability
This heavy engineering vehicle has a retractable front outrigger with a longer span up to 5.56m and a fixed rear outrigger to guarantee its stability when working. Hydraulic rear outrigger is optional to be equipped to our truck mounted crane to increase its stability and make it adaptable for more complex working conditions. In addition, hexagon sections guarantee good lateral stability of the construction crane.

3. Reliable Control System
The operation of our truck mounted crane is controlled by the main control valve directly and the outriggers are controlled by separated valves. Selector valves are employed to the lifting equipment to avoid improper operation. Both the main control valves and the outrigger control valves support both-side manipulation.

4. Great Safety
Height limit switch, over winding alarm device and high power LED lights are standard configurations to guarantee the operation safety our of our construction lifting machine. Additionally, moment limiter is optional to be installed to the hoisting equipment for higher operation safety.
