The QZ type grab bridge crane is a kind of heavy duty overhead crane to grab and load coal, ash, coal gangue and other bulk goods and materials.
This grab bridge crane is widely used in freight port, river wharf, power plants, concrete mixing station, industrial and mining enterprises.
The grab bridge crane consists of Main Girder, End Carriage, Lifting Trolley, grab bucket and Electrical Parts. Generally, the power supply System for trolley and crane are festoon system and Bus Bar system.
1. Heavy Duty and High Efficient
2. Suitable for any environment ( High Temperature, Explosion Proof and so on)
3. Long Life Span: 30-50years.
4. Easy for Installation and maintenance.
5. Reliable structure
Lifting Trolley is the most important mechanism of Crane. It includes lifting mechanism and cross traveling mechanism. The auxiliary lifting mechanism are opional according to different demands. Generally, the traveling mechanism are 1/2 drive.
The Lifting Speed from 1m/min to 40m/min and traveling speed from 10m/min to 50m/min for different usage and demands.
The trolley are assembled with motor, reducer, brake, trolley frame, drum, hook, pulley, wire rope, rain cover, wheel, bearing, buffer and other parts.
