After parking, repair the contactor or stopper, severely damaged and cannot be repaired, and must be replaced. 7 reducer oil leakage The reasons for the oil leakage of the reducer are as follows: 1) Between the reducer case and the cover, the seal ring is poorly assembled or damaged, and the seal should be removed or replaced.

My Tip: Cut off your hoist rope – Liebherr

• The hoist rope must be secured before it is released • It must be shortened by 20 times the rope diameter • It must be welded or soldered expertly • The rope binding must not come loose whilst the rope is being cut. The Liebherr Customer service team will then reset the safety cut off. After that the hoist rope must be recoiled under

Possible Solution: Whenever the frame shows evidence of damage, the hoist should be completely dismantled, all parts inspected and damaged or worn parts replaced as outlined in owners manual. Hoist control lever sticks. Possible Cause: Direct inside handle or lack of lubrication. Possible Solution: Replace handle. Hoist will not freewheel.

The damage that occurs can never be corrected and the rope must be replaced. High Stranding. High stranding may occur for a number of reasons such as failure to properly seize the rope prior to installation or maintain seizing during wedge socket installation. Sometimes wavy rope occurs due to kinks or a very tight grooving problem.

Wet ropes are going to be perma- nently damaged and will have a dras- tically shortened lifespan. No method or application that could potentially reduce the corrosive effects of humidity or condensation on an elevator rope will be able to restore a hoist rope to its original state or prolong its life.

It is a good idea to check the entire rope for wear and re spool it neatly after every use. Check the winch rope for any cut strands, fraying parts, abrasion, or heat damage from the winch. After use, all winch lines will get a little "fuzzy" from abrasion. This is normal, but if an entire strand is cut the winch line needs to be replaced or fixed.

If, however, the temperature within the rope wires exceeds approximately 300 deg C, the microstructure of the cold drawn wires will recrystallise, losing about two-thirds of the wire tensile strength in the process.

• The wire rope on a hoist must be replaced with the same part number and the same brand as originally provided on the hoist. • For maximum safety, the wire rope must be replaced when even one strand of wire is broken. Refer to OSHA guidelines for construction for more
