The inspection methods and standards for Steel Wire Rope Electric Hoists can be summarized as follows:

Inspection method

Manual inspection:

Wire breakage inspection: Check the condition of broken wires inside and outside the steel wire rope through visual inspection and caliper measurement.

End breakage: Check for wire rope breakage caused by wear and tear.

Broken wire growth rate: Analyze the accumulation of broken wire quantity over time.

Rope diameter reduction: Check for rope diameter reduction caused by damaged core.

Internal and external wear: observe the wear of the steel wire rope during repeated contact with the drum groove and pulley groove.

Rust: Check for rust on steel wire ropes caused by environmental factors such as high temperature and humidity.

Deformation: Check for changes in the shape of the steel wire rope and possible sudden fractures.

Inspection of supporting connectors: Check the firmness of various supporting devices during the operation of the steel wire rope head connection.

Instrument inspection:

Use professional instruments for more accurate measurements and evaluations, such as flaw detectors.

Inspection standards

Steel wire rope quality: Steel wire ropes should have a product qualification certificate and comply with relevant national or industry standards.

Broken wire situation: The number and growth rate of broken wires should be controlled within a safe range. If there is any exceeding the standard, it should be replaced in a timely manner.

Wear and rust: The degree of wear and rust on the steel wire rope should not affect normal use, otherwise it should be replaced.

Matching connectors: The connectors should be firm and reliable, without any looseness, damage or other phenomena.

Other precautions

Safety devices: Electric hoists should be equipped with necessary safety devices, such as lifting limiters, overload limiters, etc.

Operation and maintenance: Operators should receive professional training to understand the safe operation and maintenance requirements of the equipment.

Regular inspection: Electric hoists should be inspected and maintained regularly to ensure the safety and reliability of the equipment.
