What's a double girder overhead crane?With double girder overhead crane design, the overhead cranes adopts two girder beams to make up the crane travelling overhead which are supported by an end truck / end carriages on each side. Frequently, the double girder overhead crane are designed in top running crane configuration in which the hoist trolley or open winch trolley run on a rail or track installed on top of the overhead girders. With a double beam design, the double girder overhead cranes help to gain the depth of the cross girder if the hoist is placed between or on top of the cross girders.Double girder overhead cranes are widely recommended for heavy-duty material handling with heavier lifting capacities and longer spans. Because of this, the crane parts and components of the double girder overhead crane system, including the hoist trolley and open winch trolley, are more complex in design which makes double girder overhead cranes more expensive than a single girder overhead crane.
Main Specifications of Double Girder Overhead Crane
Double girder overhead cranes are designed for heavy material handling with capacity of more than 20 tons, thus, a double girder overhead overhead cranes also can be referred as a heavy duty overhead crane. Double girder overhead cranes can be designed with various top running crane configurations, including hoist trolley & open winch, equipped with various overhead crane attachments and below the hook lifting devices, such as grabs, tongs, magnets, spreader beams, C hook or other process lifting devices for heavy loads handling, featured as high safety, reliability, and durability, etc.

Top running vs. Under hung double girder overhead cranes
Double girder overhead cranes can be designed either in top running crane or under running crane configurations. A top running double girder overhead crane will provide the most overhead room, as well as the greatest hook height. An under running double girder overhead cranes are mounted on a runway structure that has been integrated into the ceiling structure of the building which are an effective solutions for low headroom or tight headroom clearance applications.
Usually, the double girder underhung overhead cranes are difficult and expensive. For various conditions, the double girder overhead cranes usually are adopted the top running crane designs.
Double girder overhead cranes are the first choice for heavy duty material handling in workshops which needs a very large range of crane spans, hook height and travelling speed range. Generally, the double girder eot cranes are available with multiple hoisting systems including Hoist trolley system & Open winch trolley system, depending on the wight of lifting loads and lifting requirements.
Hoist trolley for double girder overhead cranes
Crane hoist trolleys are designed for double girder overhead crane and are widely used for heavy duty lifting operations with higher safety and stability. The hoist trolley are runs on along the top of edge of two girders and the wire rope with hook will descend between the two girders to handle the load, which enables the maximum possible height of lift under the beam girder, however, on the hand more roof space will be required above the crane beams or girder, due to it sits on the top of crane beam girders.
