Final answer:
Bridge Cranes and Gantry Cranes are essential for moving heavy loads in various industrial settings. Bridge Cranes operate on runways and allow three axes of hook motion, while Gantry Cranes are supported by freestanding legs and are highly mobile, suitable for outdoor use.
Step-by-step explanation:
The Bridge Crane and the Gantry Crane are two types of material handling equipment used in various industries for moving heavy loads.
Bridge Crane
A Bridge Crane, also known as an overhead crane, consists of parallel runways with a traveling bridge spanning the gap. A hoisting system, the trolley, travels along the bridge. This type of crane is commonly used in industrial environments and can move loads up and down, as well as back and forth, providing three axes of hook motion. Bridge Cranes can be very large and are often used in settings such as warehouses and manufacturing facilities to move heavy materials.
Gantry Crane
A Gantry Crane is similar to a bridge crane, but instead of moving on suspended runways, it is supported by freestanding legs and moves on wheels or along a track at ground level. It is versatile and can be used indoors or outdoors. The mobility of the Gantry Crane makes it ideal for use in shipyards, rail yards, and other outdoor areas where large and heavy loads need to be moved in different directions.
