The LZ Type Grab Bucket Single Girder Crane is based on LDA and travels together with the grab bucket through a wire rope hoist or hoist trolley. Cranes generally work indoors, with a working environment temperature of -20 ℃ -50 ℃. The grab bucket can be customized according to customer requirements. The split type electric hydraulic grab bucket can be used in water. The relative humidity of the air does not exceed 85%. LZ Type Grab Bucket Single Girder Crane adopts a single main beam structure and uses an electric hoist as the lifting mechanism, suspended at the lower edge of the main beam for lateral movement.
For ground operation, a squirrel cage motor with a built-in flat brake is used. For operation in the driver's cab, a conical winding brake motor is used. The brake is a conical brake, and the reducer uses a one-open-one-closed or one-open-two-closed involute gear reduction device.
