AQ-LH Electric Hoist Overhead Crane

The AQ-LH electric hoist overhead crane is a sort of double girder crane primarily used in mechanical processing workshops, metallurgical plants, warehouses, storage yards and power stations to fulfill a variety of lifting requirements, such as assembly, loading, unloading, overhaul and transferring operations. The overhead crane can also replace a conventional double girder bridge crane for workshops of textile industry and food industry.

AQ-LH type overhead crane is able to handle loads that range from 5 ton to 50 ton, and it is specifically designed for light and moderate service. The cranes cannot be used in flammable, explosive or corrosive environments.

2. Low headroom
3. Light dead weight and small wheel pressure
4. Long working life, reliable and stable performance
5. Minimal maintenance and easy installation
6. Simple operation
7. Customized design

AQ-LH Double Girder Overhead Crane Hoist Design

Electric hoist is the most critical component of overhead crane as it actually performs the lifting work. Depending on the lifting medium you use, the crane hoist falls in two main configurations, wire rope hoist and chain hoist.

The crane can be classified into double hoist overhead crane, chain hoist crane and wire rope hoist crane according to hoist configurations. Each type is designed for specific purposes.

Double hoist crane: it is equipped with two electric hoists for more efficient material handling. The rated capacity of two electric hoists cannot exceed that of double girder crane.

Chain hoist crane: it performs the lifting task by using metal chain as the lifting medium. The chain hoist crane is a cost-effective option for light duty lifting applications, such as maintenance tasks. This style of hoist and overhead crane requires little maintenance and relatively low cost.

Wire rope hoist crane: it is commonly found in a variety of lifting applications such as machine shop for production tasks as the wire rope hoist is able to handle heavier loads. This form of overhead crane and hoists can also reach a greater lifting height and speed.

Special Applications of Electric Overhead Crane

The overhead crane can be specially designed for varied lifting occasions. Examples include explosion proof hoist used in flammable and explosive environments and two hook hoists for balancing loads during lifting movement in textile plant and paper plant. The selection of electric hoist is highly determined by application, environment condition and ease of use.

The crane hoist is more often mounted to a trolley to form one unit that provides accurate positioning. With respect to crane work duty, load capacity, working environment and safety precautions, the electric hoist crane has multiple control systems for you to choose from, including pushbutton pendant control, wireless remote control and cabin control.
