What is the wiring configuration utilized to connect interlocks in lifting equipment?

The series wiring configuration is commonly utilized to connect interlocks in lifting equipment due to its ability to ensure that all interlocks must be satisfied for the system to operate. This arrangement creates a single path for current flow; if any interlock is disengaged or defective, it breaks the circuit, which directly prevents the operation of the equipment. This safety feature is crucial in lifting operations, as it provides a fail-safe mechanism that helps prevent accidents by ensuring that the equipment can only function when all safety conditions are met.

In contrast, a network configuration might complicate the interlock system, while a parallel arrangement may allow for operation even if one interlock is bypassed or fails, which is not ideal for safety in lifting applications. A hybrid system could combine both methods, but for basic interlock applications, the simplicity and reliability of a series configuration is preferred.
