Rail Mounted 20 Ton Single Girder Gantry Crane

A crane is a machine used to lift objects or people. Some can also make these items or personnel move horizontally or spatially within their working range. A crane whose hoisting device is suspended on a trolley or traveling hoist that can run along the gantry is called a "gantry crane."

A rail mounted 20 ton single girder gantry crane generally consists of a gantry of a cart operating mechanism, a hoisting trolley equipped with a hoisting mechanism and a trolley operating mechanism, electrical equipment, and a driver's cab.

Main features of rail mounted 20 ton single girder gantry crane:

1. The box-shaped main beam welding structure is adopted to increase the working space and facilitate transportation, installation and maintenance.

2. The trolley conducts electricity using a special-shaped rail cable conducting device.

3. Standardization, serialization and generalization of parts and components.

4. There are two types of crane power supply: cable reel type (divided into left and right ends) and sliding contact type (divided into left and right ends), which can be selected by users.

5. The driver's cab has a wide field of vision and a built-in linkage console. Which is flexible, stable and comfortable to operate. Fans, air heaters, air coolers, air conditioners, walkie-talkies, etc. can also be added according to user requirements.

The division of the working class is determined by the utilization class U and the load state Q of the crane. Rail mounted gantry crane working level A: It reflects the working characteristics of the crane in terms of load status and utilization busyness.

The working level of the 20 ton gantry crane, that is, the working level of the metal structure, is determined according to the lifting mechanism and is divided into A1-A8 levels. it is roughly equivalent to: A1-A4-light; A5-A6-medium; A7-heavy, A8-extra-heavy.
