What is the primary purpose of load limiting devices on cranes?

The primary purpose of load limiting devices on cranes is to prevent overload and protect the equipment. These devices are designed to monitor the load being lifted and ensure it does not exceed the crane's rated capacity. When the load approaches or exceeds this limit, the device activates to alert the operator, and in some cases, may automatically restrict further lifting actions. This crucial safety feature helps to avoid catastrophic failures that could result from lifting excessive weights, thereby protecting both the crane itself and personnel working in the vicinity.

While enhancing lifting speed, increasing load capacity, and improving operator visibility are important aspects of crane operation, they do not serve as the fundamental purpose of load limiting devices. Proper load management through these devices is vital for safe crane operation and is an essential responsibility for operators.
