The SQ2SK2Q truck-mounted crane’s single-cylinder cable synchronous telescopic technology enables higher work efficiency. Advanced research and development methods ensure design reliability. Pentagonal and hexagonal boom technology has good neutrality and strong cross-section bending resistance. Compact hinge design takes up little space. Equipped as standard with an anti-overroll alarm device, the operation is safer. The integrated lifting hinge mechanism has higher working efficiency and longer life of the hydraulic system. The unique floating three-point bridge structure design effectively reduces the additional stress on the chassis girder when the vehicle is driving.
