Electric Overhead Crane

electric overhead crane, also known simply as an overhead crane or bridge crane, is a type of industrial lifting equipment commonly used in manufacturing, construction, and other heavy industries. These cranes are designed to move heavy loads horizontally along a track or runway, with a hoist mechanism that can lift and lower objects vertically.

Here are some key components and features of electric overhead cranes:

Bridge: The bridge is the horizontal beam or girder that spans the width of the working area. It is supported by end trucks on either side, allowing the crane to travel along the length of the runway.

End Trucks: These are wheeled assemblies mounted on either end of the bridge. They support the bridge and allow it to move along the length of the runway. End trucks are typically powered by electric motors.

Runway: The runway is the elevated track along which the crane travels. It is typically installed on steel columns or beams attached to the building structure.

Hoist: The hoist is the lifting mechanism mounted on the bridge. It consists of a motorized drum or winch with a hook or other lifting attachment. The hoist can raise and lower loads vertically.

Trolley: The trolley is a mechanism that moves along the length of the bridge, allowing the hoist to position loads anywhere within the crane's working area. The trolley may be manually operated or powered by electric motors.

Controls: Electric overhead cranes are typically operated using a pendant control or a cab-mounted control panel. These controls allow the operator to move the crane, raise and lower the hoist, and position loads with precision.

Safety Features: Electric overhead cranes are equipped with various safety features to prevent accidents and protect personnel and equipment. These may include overload protection, emergency stop buttons, limit switches to prevent over-travel, and collision avoidance systems.

Electric overhead cranes offer several advantages, including high lifting capacities, precise positioning of loads, and the ability to cover large working areas. They are widely used in industries such as manufacturing, steel production, shipbuilding, and logistics, where heavy loads need to be lifted and moved efficiently and safely.
