Product Description

SQ4SK truck crane adopts single cylinder cable synchronous telescopic technology, higher working efficiency. Advanced research and development means to ensure the reliability of the design. Mature pentagonal, hexagon and octagon are adopted in the section of crane jib body of SQ4SK. U-shaped circular arc arm is adopted in the latest generation of crane jib body to reduce its weight, reduce its amplitude, reduce its deflection, improve its stability and deformation resistance, and improve its lifting capacity significantly. The application of the secondary arm, the secondary winch and the secondary hook can provide the basis for the crane to operate with light load, large scale and large height, and expand the application field of the product. The application of automatic hooking technology saves the time and labor when starting and ending crane operation, which makes the operation easy and convenient. Standard equipped with anti-overwinding alarm device, the operation is safer. The integral lifting hinge mechanism has higher working efficiency and longer hydraulic system life. The unique floating three-point bridge structure design of SQ4SK crane can effectively reduce the additional stress on the chassis girder when the vehicle is running.
