How do overhead travelling cranes supply power ?

Aug 15, 2023

Overhead travelling cranes are an essential component of any industrial manufacturing unit. It provides a safe and efficient way to move heavy machinery and equipment from one location to another. But, with all that power and movement, one might wonder how these cranes actually get their own power.

Well, the answer is quite simple. Overhead travelling cranes are powered through electrical systems that connect to an external power source. The electrical system comprises of various components, such as conductors, breakers, transformers, switches, and control panels. Power is supplied to the crane through these components. And it is used to drive the crane's motor, which moves the crane along the gantry rail.

There are different methods of supplying power to overhead travelling cranes, depending on the crane's size and application. The most common method is through the use of insulated power conductors that are mounted above the crane's moving trolley. These conductors consist of copper wires that are insulated with heat resistant materials, and they provide a continuous supply of electrical power to the crane's motor.

Another method of supplying power to overhead travelling cranes is through a festoon system. This system uses a series of flat cables that are strung along the crane's gantry rail and connected to the crane's motor. The cables move along with the crane's motion and supply power to the motor as it moves.

In addition to providing power to the crane's motor, the electrical system also powers the crane's control panel. This control panel is the nerve center of the crane and is responsible for controlling the crane's movements, speed, and direction.

In conclusion, overhead travelling cranes receive their power through an electrical system that connects to an external power source. The method of power supply depends on the crane's size and application, but all cranes have a control panel that governs their movement and operation. These cranes play an important role in industrial manufacturing and have become an integral part of modern-day factories and warehouses.
