double girder overhead grab crane

Product description

Double girder overhead grab crane organized by box-weld main girder, grab trolley, cabin, long travel mechanism and control system. The load handling device is grab/ bucket which is able to grab bulk materials. The grab has open-close mechanism and lifting mechanism, grab is hung on those two mechanisms by four steel wire rope. The open-close mechanism drives the grab to close to grab material. When the grab/bucket is closed, lifting mechanism immediately start to hoist the grab, four loaded steel wire ropes bear even stress.
Garbage or waste grab crane is key device that used in the garbage feed system of garbage-cremation power plant or refuse recyling, also used in biomass plants. it is located at the top garbage 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.

There are mechanical four rope grab, two rope grab and single rope grab; Also can be divided into electric hydraulic grab and electric grab.
