What is the difference between electric single beam and electric double beam cranes?

The editor of the electric single beam crane will explain to you the difference between electric single beam and electric double beam cranes:

An electric single beam crane has only one beam, and the electric hoist is directly hung upside down on the track directly below the beam; The electric double beam crane has two parallel beams, and the electric hoist is installed on the trolley, which is placed on the track directly above the beams.

The electric single beam crane is mainly composed of an electric hoist, a metal structure, a large vehicle operating mechanism, a power feeding device, and an electrical device. It is a light and small lifting equipment that operates on an I-beam track and is divided into electric and manual types. Heavy objects are hung on it, which is relatively simple and widely used.

Double beam crane generally refers to a double beam bridge crane, English name: Dual-beam Crane。  Double beam cranes generally consist of three main parts: mechanical, electrical, and metal structures. The external image of a bridge crane is a single span flat slab bridge supported at both ends on two parallel overhead tracks and running in translation. Double beam cranes are widely used in indoor and outdoor industrial and mining enterprises, steel and chemical industries, railway transportation, ports and terminals, as well as logistics turnover departments and places.

The above is the analysis provided by the electric single beam crane editor, hoping to be helpful to you.
