Overhead cranes are lifting devices that are used to lift materials over the workshops, warehouses and stockyards. Because its two ends are located on tall concrete pillars or metal brackets, it looks like a bridge. The bridge crane's bridge runs along the rails laid on both sides of the elevated bridge, which can make full use of the space under the bridge to lift materials and is not obstructed by the ground equipment. It is the most widely used material lifting appliances.
The soft start motor driven material handling bridge crane uses variable-frequency technology, run with heavy load at low and high speed. The adjustable speed ranges from 1:10, which ensures crane run steadily and reduces impact on factory building. Combination of swing-proof technology achieves a high accuracy position of lifting items.
Type of Material Handling Overhead Crane
Single Girder Cranes: As you mentioned, these cranes consist of one bridge girder supported by two end trucks. They are generally used for light to moderate lifting tasks. Their design makes them more cost-effective and easier to install and operate than some other crane types.
Double Girder Cranes: These cranes have two bridge girders and two end trucks. They are typically used for heavier lifting tasks, as they are more efficient and durable than single girder cranes. They can also accommodate larger hooks and hoists, which can be beneficial for certain applications.
Top Running Cranes: These are the most common type of overhead crane. They are designed to run on a rail installed on top of the runway beam, allowing them to lift heavier loads than underhung cranes. They can handle several hundred tons and offer larger spans and higher lifting heights.
Underhung Cranes: These cranes are hung from the ceiling or roof structure, allowing for better utilization of space. They provide excellent side approach and maximize the width and height of the building. Underhung cranes are typically used for lighter loads and are often found in smaller factories and workshops.
