• Ambient Temperature： -20~40℃

Components of electric hoist double girder overhead cane

The Electric Hoist Double girder Overhead crane is mainly consisted of the following crane components, such as, bridge frame, trolley, crane travelling mechanism, and electrical control system.

Application of electric hoist double girder overhead crane

As one kind of common material handling equipment, the electric hoist double girder overhead crane is widely used in machinery processing workshop, warehouses, yard, plants, and other places, etc. It also can be used as an alternative for double girder overhead crane, used in production workshop of textile industry and food industry, etc.

Advantages of electric hoist double girder overhead crane

• compact structure, good rigidity,
• easy operation, low noise,
• low building height clearance,
• light weight and small wheel pressure,
• safe and reliable,  
• Attractive appearance, etc.

Features of electric hoist double girder overhead crane

1.Double girder structure makes the crane bridge have sufficient strength, rigidity, and stability.
2.Rail-in-middle box girder design thoroughly meets the requirement to strength, rigidity and stability.
3.End beams designed with simple structure can be easily installed with main beam by high-strength bolts.
4.CD or MD high quality wire rope electric hoist is used as lifting mechanism.
5.Soft starting motors with light current is used with ground control.
6.Dual-motor independent drive device is adopted to reduce the wear of rail gnawing and reduce the possibility of wheel climb off track fault, etc.
7.Motor is directly controlled by contactor, which can make the motor achieve single and double speed and reversing control.
8.Frequency converter is used to change the frequency and voltage of motor power to realize the function of speed adjustment control of motor.
9.Multiple safety protection system is adopted, including short circuit protection, no-voltage protection, emergency power off switch protection, overload limit protection, travel limit protection, zero and chain protection, ground protection, etc.

Double girder electric hoist crane s VS Single girder electric hoist crane

• Structure - A double girder electric hoist crane has one more bridge beam than a single girder electric hoist crane. Because of the double girder, they can offer greater capacity than other cranes.
• Lifting height - The lifting mechanism, which travels on the two bridge beams, is a trolley. Because the hook can be pulled up between the two beams, double girder electric hoist cranes provide a higher hook height in the available space.
• Adaptability - Because of their flexible configuration, double girder electric hoist cranes are the ideal solution for meeting the demands of special working situations such as steel industry, explosion-proof location, isolated location, and so on.

How To Choose The Right Double Girder Crane?

• When choosing a crane, you will need to take several important aspects into consideration: your application, working environment, Applications: It is of great importance to make sure our engineer has known all the details of your requirements so that they can design or help your choose a crane that suits your application most, such as safe working load, where your want to move the load to, duty cycle and so on.
• Working environment: An ordinary double girder electric hoist crane will quickly scrap in an environment that filled with corrosive gas or of extreme temperatures. So, the environment is an important element to choose the suitable crane.
• Your facilities: A double girder electric hoist crane with the span of 30 m obviously can't be installed in the factory that the longest distance can be provided between two supporter is 20 m.
