Overhead bridge crane is commonly found in a wide variety of environments and industries. From the refinery floor or the fabrication shop to automobile assembly, manufacturing, and more, overhead cranes are expected to perform consistently and reliably. At crane manufacturer, we’ve built our reputation on assembling cranes that our customers can count on, day in and day out.

Manufactures a variety of overhead bridge cranes, offering a number of solutions for specific applications. Whether you require a crane that is ergonomic and manually operated or a crane that is power driven and can handle massive loads; we can help.

As good performance crane among types of electric overhead cranes. Our bridge crane can lift loads from 1 ton to 450 tons, you can find equipment fit for all workstations. As the outstanding light and medium duty machine, it has single girder and double girder type. If you want to use it in special occasions, for example, to transport high temperature fusion material on factory, you can choose a metallurgy bridge crane. We provide you electromagnetic crane for steel factory, grab lifting device with different grabs.

Overhead Bridge Crane Applications

With versatile design options and heavy lifting capabilities, bridge cranes are ideal for a wide variety of applications. Some key industries include:

Metal Refining : Overhead cranes handle raw materials and workpieces through every step of the manufacturing process.

: Overhead cranes handle raw materials and workpieces through every step of the manufacturing process. Automotive Manufacturing : Overhead cranes are critical in handling bulky molds, components, and raw materials.

: Overhead cranes are critical in handling bulky molds, components, and raw materials. Paper Milling: Bridge cranes are used in paper mills for equipment installation, routine maintenance, and the initial construction of paper machines.

Requirements of Overhead Bridge Crane Motor

Motor of crane is repeat and short time working system, which means that the FC of overhead crane motor is from 25% to 40%. And the feature of short repeat working system is that motor power on and power off frequently. Besides, the motor often in a start and brake state, and the loads of crane is not regular, sometimes carry light loads, and sometimes transporting heavy loads, as a result, overload and mechanical shock are huge. At the same time, because of the short time work of overhead crane motor, the temperature rise is lower than long time motor in the same power.

It has large start torque. Because overhead cranes usually are start with loads, a better start performance is necessary. In addition, the bigger the start torque, the lower current the crane needs.

AQ-NLH Double Girder Overhead Bridge Crane • Lifting Capacity: 3.2~80t

• Span Length: 10.5~31.5m

• Lifting Height: 6~18m

• Lifting Speed: 0.5/3.4~0.8/5m/min

This motor has electrical speed regulation. For the high accuracy of transporting and parking loads, overhead bridge crane should be able to change speed. However, because the speed change happens frequently when crane is working, it is inappropriate to use mechanical speed governors.To adapt hard working condition and mechanical shock, motor of bridge crane is closed, and has strong mechanical structure, besides, it adopts a higher heat insulation class.

All in all, to meet the need of listed factors, manufacturer designs special AC asynchronous motor for overhead bridge crane. And this motor has two types including AQ-YZR (phase-wound type) and AQ-YZ (cage model) series. This series of motor has a good overloading ability, start performance, high mechanical strength and soft mechanical properties. Moreover, crane nameplate marks the output power when JC＝25％
