Double Girder Bridge

1. Product Introduction:
 

QE bridge Overhead Crane with double trolley is a specialized crane for lifting and moving length products. The double girder bridge overhead crane is an exceptional piece of equipment for various industries. The two beams that run parallel to each other provide a stable platform for the trolley to move along and lift heavy objects. This design also reduces the stress on the crane, increasing its lifespan and reducing maintenance costs.

 

Two electric trolleys of the bridge Overhead Crane can work together or independently.

Assemble the moving table on the outside of the two main girder, one side is prepare for the assemble and maintenance the crane move device, another side is prepare for the assemble of the trolley conductor device.

There are full field of view Cabin suspend under the main girder, there are joint control desk or single control box packed within the Cabin, assemble the sidelong ladder between the Cabin and moving table, The main girder joint with the two side end carriage which with the joint point in the middle.

 

Double girder bridge Crane Working Class A5~A6 is suitable to lift long materials(wood, paper tube, pipe and bar) in workshops or outdoors to store in factory and mines. The two trolley could work separately and at the same time.
QE bridge Overhead Crane are mainly consists of Girder frame, Crane travelling device, two lifting trolley and electrical parts. Bridge adopts box welded structure, high degree of vertical and horizontal rigidity; crane travelling mechanism adopts separate drive. It has a strong beam and a stable travelling mechanism; the emergency switch can stop any movement once any dangerous happened. It is rely on the bridge frame along the workshop rail direction moving longitudinal, the trolley along the main beam direction moving transverse and the hook lifting movement to work. It is an excellent choice where high speeds and heavy service are required. As the widely used hoisting machinery currently especially is suitable for working at warehouses and freight yard and other department it is prohibited to use the equipment in the combustible, explosive or corrosives environment.

3. Component: 

 

Double girder bridge Crane is currently widely used lifting materials, which is mainly composed of box bridge, hoisting trolley, cart operating mechanism and electrical control system. The retrieval device is two winches.

A track is laid on the main beam for the trolley to move laterally along the direction of the main beam. The main beam and the box-shaped end beam are welded, and the end beams are arranged with joints and bolted connections for the overhead frame to be disassembled and transported. The walking platform is used to place the cart running mechanism, electrical equipment and for maintenance.

 

4. Applicable Environment: 

 

Applicable Industries

Building Material Shops, Machinery Repair Shops, Manufacturing Plant, Construction works , Energy & Mining

Crane working class: A5 crane (used for less frequent work, such as general machining and assembly workshops).
 

Crane working class: A6 crane (used for more frequent work, such as auxiliary lifting in metallurgy and foundry).
 

When used in the open air with rain-proof equipment, the total weight and wheel pressure of the outdoor crane will increase by about 5%. The crane is divided into two working systems: intermediate duty (A5) and heavy duty (A6) according to the busyness of use. When selecting, the technical requirements such as working system, working environment, temperature and type of power supply should be indicated.

 

Construction: Our QE Double girder bridge Crane is ideal for lifting heavy loads on construction sites, including steel beams, concrete panels, and other building materials.

 

Manufacturing: Our Double girder Crane can be used in manufacturing plants to move and position heavy machinery, parts, and components.

 

Mining: Our QE Overhead Crane is well-suited to mining operations, where it can be used to move heavy equipment and large quantities of raw materials.

 

Warehousing: Our QE  bridge Crane can be used in warehouses and distribution centers to move and stack heavy pallets, containers, and other materials.
