Function:

The crane height limiter mainly has the following functions:
1. Preventing the hook from rising over the limit: when the hook slides up to the limit position, the height limiter can act in time to hold up the lever or touch the related device and press down the limit switch, thus cutting off the electric circuit and stopping the hook from rising, avoiding the hook from continuing to rise and pulling off the steel wire rope, which may lead to the accident of falling heavy objects.
2. Safeguard the safe operation of the crane: By restricting the hoisting height of the hook, it ensures that the crane can work in a safe operation range and prevents various dangerous situations caused by the hook rising too high, such as collision with high buildings and equipments, etc., so as to safeguard the safety of the crane and the surrounding personnel and equipments.
3. Protecting the wire rope: avoiding the wire rope from being overstretched or even broken due to excessive rise of the hook, thus prolonging the service life of the wire rope and reducing the safety hazards and economic losses caused by the damage of the wire rope.
4. Auxiliary operator: Provide the operator with a clear operating height restriction, enabling him to control the operating height of the crane more accurately, facilitating precise lifting operations and improving work efficiency.
5. Compliance with safety regulations: The installation and use of crane height limiters is a way to meet the requirements of relevant safety regulations and standards, helping companies to comply with safety regulations and avoid facing penalties for non-compliant operation.
To summarize, the crane height limiter has an irreplaceable and important role in safeguarding the safety of crane operation, which effectively prevents accidents from occurring in many aspects, and is one of the important safeguards for the safe operation of cranes.
