QDY type casting Bridge crane refers to special lifting equipment for lifting ladle or other molten metal liquid. Its design and manufacture conform to JB/T7688-1 and JB/T7688.15 and the State Quality Supervision Bureau: Quality Inspection Office Special [2007]-375 document on the overall work of metallurgical crane machinery


The lifting trolley is a single-car double hook type. There are main and auxiliary hooks on the hook (the hook distance is determined according to the requirements of the bidding documents or the standard spacing of the main hooks of the universal bridge crane trolley). The hook head is a forged hook (C-hook or W-hook). The main and auxiliary hooks can cooperate with the work (dumping metal liquid), and the hook head is provided with anti-off device for preventing the wire rope from falling off. The main lifting mechanism is a double motor, a double brake, a single reel, the steel wire rope is made of metal core, and is resistant to high temperature. A product with a high safety factor ensures safe lifting of the crane.

 There is a running mechanism on the trolley to meet the needs of the trolley running back and forth along the main beam. The running mechanism of the cart is set on the platform of the bridge, consisting of motor, reducer, brake, wheel set, etc. The wheel is double rim. Through the driving torque of the motor, the crane runs along the track of the cart to realize the overall lifting of the crane. .


 The electrical control of QDY casting Bridge crane basically adopts the standard type of casting crane. It is suitable for high temperature, dusty and busy work. The motor adopts H-type insulation grade and has over-speed protection. The brake device uses double brake. The safety factor and protection level of electrical components are in line with the basic requirements of casting cranes. The lifting mechanism is equipped with various safety protection functions such as overload limit protection and double limit protection of rising limit. Safety protection level is higher than ordinary

QDY double girder casting bridge crane:

 According to the working characteristics of the crane, the cranes can adopt advanced speed control methods.

To ensure better work, such as the use of stator voltage regulation (or frequency control), and the use of PLC control to achieve speed control and crane operating conditions, safety faults and other functional displays. Other control methods, such as remote control, can also be used. Thereby better reflecting the excellent performance of the crane.
