Product Introduction
1. Product Introduction:
Double girder cranes generally refer to double girder bridge cranes. The crane's double-girder design has greater stability and support, reducing the risk of accidents and equipment damage.
50 ton Double Girder Bridge Crane With Double Winch Trolley are generally composed of three major parts: mechanical, electrical and metal structures. According to different utilization levels and load conditions, it is divided into two working levels: A5 and A6. This crane has two trolleys. The two trolleys can be used at the same time or separately. They are used in workshops or open-air warehouses of factories and mines to lift long materials.The shape of the bridge crane is like a single-span flat bridge whose two ends are supported on two parallel overhead rails.
Different from ordinary double girder overhead cranes, it has two running winches devices, it is used in indoor and outdoor industrial and mining enterprises, iron and steel chemical industry, railway transportation, port terminals and logistics turnover and other departments and places. According to the frequency of use, it is divided into three working Class: A5-A8. Its action manipulation is all done in the driver's cab.

3. Component:
Double Girder Overhead Crane with Double Winch Trolley is currently widely used lifting machinery, 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 bridge 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:
Double Girder Overhead Crane With Double Winch Trolley equipped with hooks are suitable for lifting work in machining, assembly workshops, metal structure workshops, metallurgy and foundry workshops and various warehouses; Equipped with grab buckets, it is suitable for metallurgical, cement, chemical and other industrial sectors or open-air fixed-span handling of bulk materials. In addition to being suitable for the loading, unloading and handling of ordinary heavy objects, the Double Girder Overhead Crane with Double Winch Trolley can also be equipped with a variety of spreaders for special operations.
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 (A5) and heavy (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 double overhead crane is ideal for lifting heavy loads on construction sites, including steel beams, concrete panels, and other building materials.
Manufacturing: Our bridge crane can be used in manufacturing plants to move and position heavy machinery, parts, and components.
Mining: Our double bridge crane is well-suited to mining operations, where it can be used to move heavy equipment and large quantities of raw materials.
Warehousing: Our crane can be used in warehouses and distribution centers to move and stack heavy pallets, containers, and other materials.
5. Wearing Parts:
The wearing parts of Double Girder Overhead Crane with Double Winch Trolley include Load limiter, Coupling, limit switch and buffer.
6. How to operate
Aerial operation refers to cab operation.
Under the premise of strictly abiding by various rules and regulations, the crane driver should do the following five points in operation.
(1) In the process of operating the crane, the driver must start, brake smoothly, and the hook, spreader and hanging objects do not swing.
(2) On the basis of stable operation, the hook, spreader and hanger should accurately stop and land above the designated position.
(3) On the basis of stability and accuracy, coordinate the actions of corresponding crane mechanisms, shorten the working cycle time, ensure the continuous operation of the crane, and improve production
efficiency.
(4) Make sure that the crane works reliably and effectively when it is in good condition. During the operation, strictly implement the safety technical operation regulations of the crane, and prevent any personal and equipment accidents.
(5) On the basis of understanding the performance of the crane and the mechanical characteristics of the motor, operate the controller correctly and achieve reasonable control according to the specific conditions of the hanging objects.
