The grab bridge crane as the spreader can be used for unloading, stockpiling, reversing, retrieving and loading during raw material preparation operations. The grab bridge crane is widely used in the hoisting operation of general cargo in various factories and mines, and it is equipped with a special spreader such as a grab bucket for special operations. How to standardize the operation of the grab crane is as follows:
1. Check before operation: whether the mechanical, electrical, and safety devices are in good condition; whether there is bumping, jamming, or hanging on the grab crane; confirm that everything is normal, and start the trial run after ringing the bell for alarm.
2. You must concentrate on the operation.
3. During the operation, it is necessary to always achieve steady rise, steady movement and steady landing. When approaching adjacent vehicles or approaching people, you must ring the bell in time to warn.
4. The grab crane insists not to pass over people and the crane when grabbing items;
5. When running, the crane should stop running immediately when anyone sends a stop signal.
6. During the lifting process, it is not allowed to operate two mechanisms at the same time (that is, the grab crane, trolley, and grab bucket cannot be operated at the same time).
7. Under normal circumstances, the grab crane or trolley is not allowed to accelerate suddenly, stop suddenly or run in the reverse direction suddenly, and it is not allowed to run at the highest gear.
8. When going up and down the crane, it is necessary to pass through the ladder platform. Do not walk from one crane to another. Do not walk along the track.
9. It is not allowed to stack goods on the grab crane, and the tools should be fixed.
10. When there are more than two grab cranes on the same track, they are not allowed to push each other.
11. When the grab is running without load, it should be raised to a height of more than 2 meters.
12. When dealing with faults or leaving the crane, the controller must be placed in the "0" position and the power supply must be cut off. Do not hang heavy objects off the crane. Park the trolley at one end of the cab when leaving get off work, and place the grab flat on the bulk cargo on the ground.
13. Crane wire ropes and cables should be properly wound on the drum.
14. When the grab is working, in order to avoid items from falling out, the grab should be tightly closed and not shaken.
15. Before the grab crane moves, the trolley and the grab must be moved to the middle of the driving girder to keep the truck moving smoothly. It is not allowed to move the grab crane after the grab grabs heavy objects.
The technical performance of the grab bucket has been improved through the research and years of operation experience of Henan flag crane Co., ltd technicians. Flagcrane provides standard and non-standard cranes and spreaders that have passed third-party certification. Welcome to flagcrane's factory visit.
