double girder overhead grab crane-Kingda crane-top crane manufacturer in China

Product description

Double girder overhead crane is organized by box-weld main girder, grab trolley, cab, long travel mechanism and control system. The load handling device is grab/bucket which is able to pick up, transport and deposit bulk materials. The grab has switching mechanism and lifting mechanism, grab is hung on those two mechanisms by four steel wire rope. The switching mechanism drives the grab to close to grab material. When the grab is closed, lifting mechanism immediately start to hoist the grab, four loaded steel wire rope bears even stress. Garbage grab crane is key device that used in the waste feeding system of waste-energy power plant.it is located at the top refuse storing pit, and used for feeding, conveying, mixing, fetching and weighting of garbage. The crane can implement lifting-conveying work, strictly ensure normal garbage-cremation power plant's running. this crane can be controlled by hand, semi-automation and automation.

Double girder overhead grab crane mainly services for waste to energy power plant, refuse incineration power plant and cogeneration power plant.
On the grab trolley, motor-hydraulic multi-jaws grab can be hung, and clam-shell mechanical grab also can be used on double girder grab crane.
