5 Types of Ceiling Mounted Bridge Cranes

According to the different lifting capacity, if the lifting capacity is larger, such as more than 2 tons, choose the double girder form than single girder operation is more stable and better performance

In more complex working conditions, such as the intersection of multiple equipment or extremely limited space in the area, you can choose to increase the telescopic beam to cover the area where the ordinary lifting machinery can not enter the area of the crane for lifting

If the requirements for positioning accuracy is not strict, it is recommended to use flexible connection ceiling-mounted overhead travelling crane, the cost is lower, the structure is more lightweight, and if there is a high requirement for precise positioning, it is recommended to choose rigid connection method to achieve accurate alignment. The cost is lower and the structure is lighter. If the requirement of positioning accuracy is high, it is recommended to choose the ceiling-mounted overhead travelling crane with rigid connection to realize accurate positioning.

Flexible Single Girder Ceiling Mounted Bridge Crane

Lifting capacity: 80 kg- 1 ton

The use of a single main beam and monorail running trolley form, suspended from the ceiling requires ground space, low cost, lightweight structure, suitable for small tonnage, and low-frequency lifting

Flexible Double Girder Ceiling Mounted Bridge Crane

Lifting capacity: 125kg-2ton

The two main girders are connected in a flexible way to span between the rails, compared with the flexible single girder, it can be more stable to lift the materials, with larger lifting capacity and better stability, and the electric hoist trolley moves between the two main girders to lift the goods.

Telescopic Beam Suspension Workstation Crane

Lifting capacity: 80 kg- 2 ton

Telescopic beams hanging below the main beam can expand the coverage area to a certain extent, suitable for short trips and workstation supplemental lifting operations

Rigid Connection Single Girder Ceiling Mounted Bridge Crane

Lifting capacity: 80kg-2ton

The rigid beam is relatively thick and has no elastic deformation. The electric hoist trolley runs smoothly along the track under the main beam and can accurately lift heavier goods.

Rigid Connection Double Girder Ceiling Mounted Bridge Crane

Lifting capacity: 125kg-3ton

The two main girders are rigidly connected to span between the rails, which provides a heavier load, high positioning accuracy, anti-swinging, anti-diagonal pulling phenomenon, and prevents the main girder from jamming while moving easily, supporting customization of medium-length travels and larger spans, and wider coverage areas.
