Overhead hoists are typically utilized in factories or industrial facilities where heavy objects need to be lifted and moved. These electric hoists are typically attached to horizontal beams which pass over top of several different work stations. These beams also serve as a track for the hoist to travel along. Once an object has been lifted in one location, the hoist can carry the object to another work station and lower it for additional work or processing.
There are many different types of control systems used to operate overhead hoists. Some hoists are operated manually, others use wireless control systems, and still others are operated from a control cabin attached to the hoist. Manually operated hoists are generally used for much smaller loads while the biggest hoists typically require the operator to use an electronic or pneumatic control system.
In addition, hoists may use various types of lifting methods depending on the application. Steel cable and rope are often used since these can stand up to the heavy-duty lifting required in many manufacturing applications. These cables or ropes can be fitted with hooks or clamps to accommodate many different objects and equipment.
Since they are usually bolted to the walls or into large load-bearing columns, overhead hoists are not as mobile as other types of hoists. For this reason, they are most often found in workshops where they are not required to frequently change positions. Overhead hoists are available in multiple configurations. They differ by load capacity, line material, line length, and maximum loaded line speed. Choosing the machine that fits the needed specifications is important, because safety issues can arise if overhead hoists are misused.
