In this article, we will explore the key features of bridge cranes and their various applications in heavy lifting. Understanding how these cranes work and their benefits will help businesses choose the right equipment for their specific needs and improve their overall operational efficiency.
1. What is a Bridge Crane?
A bridge crane, also known as an overhead crane or a traveling crane, consists of a hoist, bridge, trolley, and supporting structure. It is designed to lift, move, and lower materials from one point to another within a designated area. Unlike traditional cranes, which are often stationary or mobile, bridge cranes are designed to move along a set of rails or tracks, often positioned above the workspace, hence the term “overhead.”
Key Components of a Bridge Crane:
-
Bridge: The horizontal beam that spans the workspace and moves along the rails. The bridge provides the structure for the crane to move and carry the load.
-
Trolley: The mechanism that moves the hoist along the length of the bridge. The trolley is responsible for positioning the load along the bridge.
-
Hoist: The lifting device that raises and lowers the load. The hoist is usually powered by an electric motor, though manual hoists are also available for lighter loads.
-
Rails or Tracks: The tracks along which the bridge moves, providing the necessary space for horizontal movement within the crane’s operating area.
-
Supporting Structure: This is the foundation or framework that holds the entire crane system in place, often mounted on the building’s ceiling or on large columns.
bridge crane are available in a variety of configurations to suit different lifting needs and facility layouts. Some cranes are designed for light loads and small spaces, while others can handle extremely heavy materials in large, open environments.
