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.
Types of Double Girder Overhead Cranes for Sale
The following overhead double girder crane designs listed below are commonly used for double girder overhead cranes. Our most popular double girder overhead cranes are the QD and LH. Our company also sells European overhead cranes such as the QDX and NLH overhead cranes. The European overhead crane structure is much more compact and beautiful, the dead weight is lighter, and the entire crane uses frequency conversion and double speed lifting, making it more stable for your use.
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.
