An overhead crane, which is sometimes known as a hoist overhead crane or a hoist bridge crane, is a type of crane that operates in one location for long periods of times. They are typically used in manufacturing, warehousing, or shipping locations but can be found in other places as well. The name overhead crane comes from the fact that they move around on a metal beam that is above the main working area. This allows the crane to take heavy objects from one area, and bring them to another area, very efficiently.
Components of an Overhead Crane
Frame of the Crane: The main frame of the crane will be the metal beam on which it travels, and the support structure on which it rests. This support structure can be a part of the overall construction of the facility, or a separate structure used exclusively for the crane itself. Either way, the frame must be able to hold the total weight of the crane, plus anything that it will be lifting, to operate safely.
Lifting Mechanism of the Crane: The lifting mechanism is the hoist itself, which can be a hook, a grabbing device, or some other type of device. This is what will attach to the objects that need to be moved so that they can be lifted. This lifting mechanism needs to be able to hold the weight of the objects being moved and keep them steady while in motion.
Drive System: The drive system are the motors that are used to move the crane and lifting device to the location where it is needed. Depending on the design, this may be one motor that moves the lifting mechanism back and forth or could include multiple motors that potentially move the support beam as well. This would allow a greater range of motion for the crane. In most situations, the drive system is powered by electric motors.
Control System: The control system is where the crane operator will be located. It allows the operator to make the crane move, raise or lower the load, and perform other tasks. In addition, the crane’s safety and protection system are typically centered in the control system. This can help to protect the crane from being overloaded, having electrical problems, and more.
