Double girder gantry crane is mainly consisting of the skeleton structure, lifting and cross traveling mechanism, long traveling mechanism, cabin and electrical control system. The trolley can move horizontally on a pair of rails on the beam. The girder can be box or trussed type in according to your working environment situation.

Trolley Part: It includes motor, speed reducer, brake, coupling, wheels, and coiling blocks. No asbestos brake pad and brake block insert use card outfit, safe and reliable; The speed reducer use hard-toothed surface reducer, compact structure, durable; Trolley travelling use separate drive; Have high loading ability, long service life moving stable; Equipped with the derailment prevention board; Used for Angle round box, equipped with buffer device; Modular design, meet customer needs.

Electric System: Module control speed, micro-speed and double speed; Traveling and lifting smoothly; The power for trolley moving adopts flat cable, sliding smoothly; Control box layout is reasonable, easy to repair; Protection class IP55; Optional main power source ; All external cable line number with mark; Safety smooth touch line, high conductivity, small pressure drop; Light weight, installation convenience; Set electric taxi speed is high, ensure continuing power supply; Optional speed control module, and can realize the micro speed and double speed.

Protection Devices: Preventing hook clashing the top, set shields and barriers Circuit self-test protection device, running the travel limit protecting the current lacking of any phase. Outdoor cranes are equipped with lifting mechanism, electrical control box and rainproof devices. Anti-collision, sound and light alarm devices. Equipped with rail clamp. Lifting weight limitation, height imitating, rail clamping device speeding protection, zero pressure protection, the lightning protection

Operation Device: Cabin room, eye shot is open, Linkage machine control, easy to operate Double block button or lever type lever, Smooth operation and accurate Remote control, no need of professional driver. Following type or slide-independent, non-following suspension Protection class IP65 Life of 500000 times; remote control, very easy; with strong waterproof, fight broke performance
