QLYS25HZ “Dual-power” Hydraulic Wheeled Straight Boom Grabbing Crane “Dual-power” Hydraulic Wheeled Straight Boom Grabbing Crane is the renewal hydraulic grabbing crane based on autoMobilee crane. The working and driving of this crane are both finished in a control room in the upper part of crane, and also it can hoist 30％(when the main boom working) Hoisting weight To drive and move. The moving, turning, hoisting, amplitude of variation and grabbing working of this grabbing crane are all oil-operated, which has stable performance and stepless velocity modulation. Fireproof electric machine and totally-enclosed type motor and circuit are safe when working in key fireproof institution. Fitted with different hydraulic grabber, the crane can load and unload, stack and unstuck to different raw material, such as coal, sand, grass, wood and wastepaper and so on, is the best choice of reservation of raw material to papermaking, cotton and wood industry. According to the concrete requirements of different clients, we produce electricity-operated crane, internal-combustion engine and “dual-power” type operated by engine and electricity at the same time, can meet the requirements in different stock place. The concrete type as follows: QLYS represents internal-combustion engine, 380V electricity engine. “Dual-power” operated type (the upper part of crane control operation and driving). QLYD represents 380V electricity-operated crane(the upper part of crane control driving, the below part of crane control operation). QLY represents internal-combustion operated type crane(the upper part of crane control driving). |
