Years ago, pendant controls used to go out with just about all types of overhead crane systems. As the prices of radio control systems dropped, they became more widely-used. Pendant systems are still very popular today because of their reliability and ergonomic design changes to make them more comfortable for the operator to use. Today’s pendant design is a much smaller and lighter piece and can be operated using one hand.
The most important advantage that pendant controls have is their reliability. Because they’re hard wired into the hoist or a festoon system, there is no interference between a remote radio transmitter and the receiver.
Due to their rugged design, pendant controls are highly resistant to mechanical damage and contaminants. Some of the benefits of their design include:
Although pendant controls can be used on almost any type of overhead crane, they are ideal for cranes that are in lower duty cycle classes. Because it is hardwired into the electrification system, the crane controls will always have power, so the operator doesn’t have to worry about replacing or charging batteries for a crane that doesn’t get used too often. Often, pendant controls are the preferred control method for explosion proof cranes.
Compared to radio controls, the pendant is always readily available since it hangs down from the crane itself. The operator doesn’t have to worry about finding it or keeping track of it like they would with a radio transmitter.
