QAY25 All Terrain Crane adopts 4-section box type powered telescoping, with all-round hexagonal boom profile, made of high-tensile structural steel, with longitudinal reinforcement for improving partial stability of boom lower plate, better lateral rigidity for boom. 5 sheaves at boom head, the 2nd, 3rd sections and the top one synchronously telescope, telescoping system contains double-action cylinder and wire ropes, and with holding valve fitted in the cylinder. 2-axle chassis with environment engine, all axle drive, all wheel steering and crab walk possible, equipped with advanced hydro-pneumatic suspension and off-road tires, suitable for variable complicated ground conditions. The vehicle can travel on various rough road, operate 360°full circle, and also on mid-extended outrigger or on tires, and travel with a suspended load.
