What is the difference between overhead cranes and gantry cranes?

Overhead cranes and gantry cranes are two common lifting equipment, mainly used for handling heavy objects in industrial and construction fields. Their main differences are as follows.

Overhead Crane

Structure:

Overhead cranes typically consist of a bridge spanning across a factory or warehouse. The two ends of the bridge are supported on a high track. There is a small car on the bridge, which is equipped with a lifting mechanism (crane) that can move horizontally along the bridge.

Usage environment:

Bridge cranes are commonly used in indoor environments, such as factory workshops, warehouses, etc. Suitable for places that require frequent and precise handling of heavy objects.

Operation mode:

The bridge of the overhead crane is fixed on the high track of the building. The car can move along the bridge. The bridge itself can also move along the track. So as to cover the entire work area.

Gantry Crane

Structure:

The gantry crane consists of a bridge and two supporting legs, which are installed on the ground track. There is a small car on the bridge, which is equipped with a lifting mechanism that can move horizontally along the bridge.

Usage environment:

Gantry cranes are commonly used in outdoor environments, such as docks, storage yards, etc. It can also be used indoors without fixed support structures. Suitable for working conditions that require movement, such as places where heavy objects need to be transported in multiple locations.

Operation mode:

The supporting legs of the gantry crane are installed on the ground track and can move along the track. The trolley on the bridge can move horizontally, covering the entire working area.
