Electric hoist pulley daily inspection includes pulley inspection, hook inspection, wire rope inspection, etc., electric hoist pulley maintenance precautions include regular lubrication, check the crack, check the degree of wear and so on.
Electric hoist pulley daily inspection content:
1.Pulley inspection:
Check whether the pulley rotates flexibly, without blocking and collision phenomenon.
Check whether there is severe friction between the pulley groove and the wire rope or whether the wire rope is out of the groove.
Check the wear degree of pulley, beyond the design allowed wear range should be scrapped.
Check whether the pulley shaft is firmly connected, whether the rolling is flexible, and whether there is abnormal noise.
2.Hook inspection:
The hook should be flexible in the circle 360 degrees and vertical 180 degrees.
Check that the hook nut locking device is normal and the hook mouth locking device is normal.
3.Inspection of wire rope:
Check the fixing of the end of the wire rope and must always be in a good state of lubrication.
According to the GB5972-83 standard, if there is a dense wire break or a strand break, it should be scrapped.
4.Electrical part inspection:
Check whether the suspension cable of the flashlight door is firm and reliable, and there is no damage.
Check whether the operation button interlock device is reliable to ensure that the electric hoist action is accurate.
5.Inspection of safety devices:
Check whether the brake and limit are sensitive and reliable to ensure the safe use of the electric hoist
Electric hoist pulley maintenance precautions:
1.Regular lubrication:
Fixed check once a month, and lubricate the pulley to ensure its good working condition.
2.Check for cracks:
Focus on checking whether there are cracks in the pulley, if so, it should be scrapped immediately, and it is prohibited to continue to use through welding cracks.
3.Check the degree of wear:
If the pulley has severe friction or wear beyond the range allowed by the design, it should be scrapped immediately and replaced with a new pulley.
4.Strong connection:
Check whether the pulley shaft is firmly connected. If there is any problem, it should be repaired or replaced in time.
5.Avoid hanging for long periods:
When the electric hoist stops working, it is strictly prohibited to suspend the heavy object in the air to prevent the parts from permanent deformation.
In addition to daily inspection and maintenance, it is also necessary to carry out more in-depth maintenance and troubleshooting of the electric hoist. For example, for problems found in daily inspections, timely maintenance or replacement of parts is required; For the electric hoist with frequent work, minor repair, medium repair and major repair should be carried out according to the maintenance cycle, and the maintenance content should be recorded in detail.
