Bridge Crane System

1. Product Introduction:

 

QB bridge crane system is composed with Girder frame, Crane travel device, and the trolley with lifting and moving device. There are Pave the rail for the trolley move on the main girder.

 

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 is a full-view Cabin suspend under the main girder, and a combined console or a single control box is installed in the cabin, assemble the sidelong ladder between the Cabin and moving table, The main girders are connected with the end carriages on both sides.

3. Component:

 

The advantages of QB bridge crane system are: The bridge frame adopts box-shaped main beam, which is automatically welded by submerged arc welding; The electric conduction of the trolley adopts a new I-beam track cable conduction device; The hoisting mechanism can also be provided with a second set of reliable devices according to requirements; Standardization, serialization and generalization of parts and components.

 

QB bridge crane system is made from high-quality materials designed to withstand extreme weather conditions and harsh environments. The crane is also equipped with advanced safety features such as overload protection, emergency stop, and warning devices, ensuring the safety of the user and the load.

 

4. Applicable Environment:

The QB bridge crane system is an explosion-proof bridge crane suitable for working in Zone 1 and Zone 2 of the explosive gas environment or Zone 21 and 22 of the combustible dust environment. It is suitable for general hoisting operations in places such as machinery, chemical workshops, warehouses, stockyards, loading, unloading and maintenance of medium and light duty flammable and explosive mixtures.

 

Explosion-proof Double Girder QB bridge crane system Overhead Cranes generally work indoors, the working environment temperature is -20°C~+400°C, the relative temperature is not more than 90% (when 250°C), and the working environment air pressure is 0.08MPa ~ 0.11MPa.
