Daily maintenance work content of electric single girder cranes and bridge gantry cranes

When the enterprise uses bridge cranes and gantry cranes, it is necessary to do a good job of daily maintenance of the equipment, which can not only reduce the failure rate of the equipment during use, but also extend the service life of the crane. The editor of our factory introduces the daily maintenance work of the under-bridge (gantry) crane, electric single-beam crane and กึ่ง gantry รถเครน:

Daily maintenance of bridge (gantry) crane:

1.  During the no-load test, whether each mechanism can operate normally and whether there is any abnormal noise.
2.  Check whether the travel switches at both ends of the large and small cars are complete and reliable, and whether the buffer device is intact, and pay special attention to whether the rising limit is reliable.
3.  Whether the brake is braked reliably; the brake shoe contacts the brake wheel well and smoothly during braking; the brake shoe gap is even when the brake shoe is loosened; the brake wheel has no cracks or damage, and no friction caused by the fixed rivets of the shim Scratches.
4.  Check whether the wire rope winding on the drum and pulley is normal, whether there is de-grooving, stringing, knotting, twisting, etc., whether the wire rope pressing plate bolts are fastened, and whether there is a double nut anti-loosening device.
5.  Check the wear and tear of the wire rope, whether there are broken wires, etc., and check the lubrication condition of the wire rope.
6.  Check whether there is any foreign matter obstructing the operation on the track.
7.  The hook is fixed reliably, the rotating part is flexible, there is no crack, no peeling, whether the anti-loosening device of the hook nut is complete, and the dangerous section of the hook is not more than 5% of the original height.
8.  The pulley has a device to prevent the wire rope from falling off the groove, the cover is intact and undamaged, the pulley has no cracks, and the rim has no defect.
9.  Check the fastening of the metal structure and the connecting parts of the transmission part.
10.  Whether the bracket of the collector and the flexible cord are stuck or jammed.
11.  The movable parts exposed on the traffic that may hurt people have protective covers
12.  The interlocking switches of the platform hatch, end beam door, and platform railing door of the cab on the cab are normal and effective
13.  Whether the anchor and rail clamp are in good condition
14.  There is no suspended matter on the road
15.  No dust in the cab, no cigarette butts, and no damage to the glass. 16 Clean the dust of the crane every shift, and clean the crane once a week to remove the dirt on it.

Daily maintenance of electric single-beam (or half-door) crane:

1.  During the no-load test, whether each mechanism can operate normally and whether there is any abnormal noise.
2.  Check whether the brake of the cart is good, the travel switches at both ends are complete and reliable, and the buffer device is intact, pay special attention to whether the rising limit is reliable.
3.  Check whether the main hook is slipping during operation, and report for repair and adjustment in time.
4.  Check the wear and tear of the wire rope, whether there are broken wires, etc., and check the lubrication condition of the wire rope.
5.  The hook is fixed reliably, the rotating part is flexible, there is no crack, no peeling, the insurance is intact, the anti-loosening device of the hook nut is complete, and the dangerous section of the hook is not more than 5% of the original height.
6.  Visually inspect the fastening of the metal structure and the connecting parts of the transmission part.
7.  Whether the bracket of the collector and the flexible cord are stuck or jammed.
8.  Check whether the remote control or hand-operated controller is in good condition.

The daily maintenance of the crane is very important, and it is hoped that the user should pay attention to it.
