Wire rope breakage in low clearance electric hoists can occur due to various reasons. Here are some of the primary factors that contribute to this issue:

Overloading:

Operating the hoist beyond its rated capacity can cause excessive stress on the wire rope, leading to breakage.

Overload protection mechanisms, if not properly functioning or ignored, can fail to prevent overloading.

Wear and Tear:

Over time, the wire rope undergoes wear and tear due to friction with pulleys, sheaves, and other components.

Excessive wear can weaken the rope's structure, making it susceptible to breakage.

Improper Use:

Twisting, kinking, or abrupt stopping of the wire rope during operation can cause internal damage and increase the risk of breakage.

Using the hoist in a manner that exceeds its design specifications, such as operating at extreme angles or speeds, can also lead to rope failure.

Defective Manufacturing or Material:

Defects in the manufacturing process, such as poor welding or improper heat treatment, can weaken the wire rope.

Inferior materials used in the production of the wire rope can also reduce its durability and strength.

Environmental Factors:

Exposure to corrosive environments, such as chemicals or moisture, can degrade the wire rope's material and reduce its lifespan.

Extreme temperatures can affect the rope's tensile strength and flexibility, increasing the risk of breakage.

Maintenance and Inspection Neglect:

Failure to regularly inspect and maintain the wire rope can lead to undetected wear, damage, or corrosion.

Inadequate lubrication can increase friction and wear on the rope, accelerating its deterioration.

Design Limitations:

The low clearance design of the electric hoist may limit the space for proper rope management and inspection.

Compact designs may also require the use of smaller diameter wire ropes, which may have lower tensile strengths compared to larger ropes.
