The major disadvantage of using a pendant control is that it puts the operator close to the load at all times. Especially when working with heavy loads and/or hazardous materials like hot metals or chemicals, putting the operator near the load can increase the chance of an accident or exposure to harmful materials.
Another major disadvantage is that the operator has to follow the load along the floor of the facility, and this can increase the risk of a trip or fall hazard. The operator has to be aware of material or obstacles on the floor and also know where their co-workers are working and what machinery or equipment is operating nearby.
Overhead cranes that are in high-use duty cycles, can move up and down the runway quickly and it can be difficult or impossible for the operator to keep up using a pendant system. In situations where a process crane or a Class D, E, or F crane are being used, it’s much more practical for the operator to control the crane from a cab or by using a radio control.
Finally, the pushbutton controls can get caught on machines or other obstructions within a crane bay, which can cause the pendant to become disconnected from the crane. In addition, the wires inside the pushbutton cable can break over time due to pulling and catching on obstructions and obstacles as it moves down the crane bay.
