An overload limiter is a safety feature in lifting machines that stops them from lifting loads heavier than they're meant to. It does this by measuring the weight being lifted and comparing it to a set limit. When the weight nears or exceeds this limit, it triggers a warning, stops the lifting, or even shuts off the machine. This helps prevent accidents caused by lifting too much weight and keeps everyone safe.

The wire rope guide is a component designed to guide and control the wire rope's movement. It helps maintain the rope's alignment and prevents it from deviating from its intended path during lifting and lowering operations. The guide ensures that the wire rope wraps around the drum uniformly, minimizing the risk of rope slippage or jamming.

Wire Rope:

The wire rope is a key component responsible for lifting and supporting the load. It consists of multiple strands of metal wires twisted or braided together to form a strong and flexible rope. These ropes are typically constructed from high-strength steel wires that provide durability and resilience.

Functions of Wire Rope:

• Load Bearing: The primary function of the wire rope is to bear the weight of the load during lifting operations.
• Transmission of Force: It transmits the lifting force from the hoist's drum to the load being lifted.
• Flexibility and Strength: Designed for flexibility, durability, and high tensile strength to withstand heavy loads and repeated use.

Wire Rope Guide:

The wire rope guide is a component designed to guide and control the wire rope's movement. It helps maintain the rope's alignment and prevents it from deviating from its intended path during lifting and lowering operations. The guide ensures that the wire rope wraps around the drum uniformly, minimizing the risk of rope slippage or jamming.

Functions of Wire Rope Guide:
