Warehouse Use Double Girder Gantry Crane with Flexible Movement and High Precision Positioning System

What is an Double Girder Gantry Crane?

Double Girder Gantry Crane also double beam gantry crane is a type of heavy duty gantry crane, one of the most frequently used gantry crane. A double girder gantry crane is a type of overhead crane in which the bridge girder or beam is supported by gantry legs that moving on ground track at both ends or on one ends.

The gantry frame, consisted of main beams, end beams, legs, lower beam, trolley running track, and cab, hoist trolley, crane running mechanism, and electric control system are the main components.

The hoisting trolley is outfitted with a hoisting mechanism as well as a trolley running mechanism that runs laterally along the trolley track on the bridge's main girder.

The main girder of gantry cranes can extend out of the legs to one or both sides to form a cantilever to increase the gantry crane's lifting coverage, but the length of the cantilever is usually less than or equal to one-third of the span length.

Main Types and Configurations of Double Girder Gantry Cranes

Double girder gantry cranes are a type of overhead crane that features two girders supported by legs that run along rails or wheels. These cranes are used in a variety of industries for lifting and moving heavy loads over a wide area. There are several different types of double girder goliath cranes, each with its own unique design and application.

Box type double girder goliath crane -The box type double girder goliath crane is a common type of crane that features a box-shaped girder for added strength and stability. This design allows the crane to handle heavy loads with ease, making it ideal for applications such as steel mills and shipyards.

Truss type double girder goliath crane - The truss type double girder goliath crane features a triangular truss structure that provides additional support and stability. This design is often used in applications where the crane needs to be lightweight and portable, such as in construction sites and workshops.

Full gantry crane - The full gantry crane is a type of crane that is mounted on rails that are level with the ground, allowing the crane to move along the rails. This design is often used in outdoor applications such as shipyards and construction sites.

Semi-gantry crane - The semi-gantry crane features one end of the crane supported by a leg that runs along a rail at ground level, while the other end of the crane is supported by a structure such as a building or a mast. This design is often used in indoor and outdoor applications where space is limite. Check single girder semi gantry crane & double girder semi gantry cranes.

Rail mounted gantry cranes (RMG) - The rail mounted gantry cranes are designed to move along rails that are installed on the ground. They are typically used in container terminals and intermodal yards for loading and unloading shipping containers from trucks and trains.

Rubber tyred gantry cranes (RTG) - The rubber tyred gantry cranes are equipped with rubber tires that allow them to move independently of rails. They are commonly used in container terminals, but can also be found in manufacturing facilities and warehouses.
