An electric hoist is a device powered by electricity used to lift, lower and even move heavy objects or locomotion difficult. Its main function relieve tension and prevent possible injury to any person who needs to lift a heavy object, or in situations where the object is simply too heavy to be lifted by a human without help.
The electric hoists are found in several areas of work. They are commonly used in construction, warehouses, workshops, garages, car maintenance, shipyards and large vessels, but there were several other assignments for equipment, such as lifting tree trunks or download a large chandelier for maintenance and cleaning.
How does an electric hoist
Initially, the hoist is attached to a solid support load, such as a mobile gantry crane jib or steel beam or even just a sturdy hook stuck firmly. Once attached, the chain hoist system can be lowered when using the control pad near the item to be lifted that is then attached to the load, but if necessary, a current or suspenders can be used and found near the center of gravity of the object, which ensures a balanced suspension and resilient. The sling (suspenders) is connected to the hook chain hoist and then the item is ready ready to be lifted slowly until you are sure of its stability.
Electric hoists are used to lift heavy objects
Most electric hoists incorporates some sort of safety mechanism to prevent sliding loads and overload, which can be extremely dangerous. Pulley usually work with a clutch system, which allows the chain between a programmed torque which prevents any overload. In some electric hoists, the overload limit is mechanically operated by chain involved with a switch mechanism. Hoists have modern safety switches that cut the power automatically if there is a problem with the system.
There are several reasons to use an electric hoist. The main thing is safety, because this equipment can greatly reduce the risk of injury due to the fact that it is the elevator that takes all the weight, not the individual. Are notorious problems of job security due to the lifting or moving heavy objects or until soft.
Advantages of electric hoist include cost savings and greater safety
This leads to the next advantage of cost efficiency. Electric hoists are economically efficient because, firstly, can sustain objects would need 3, 4 or more men to lift, reducing the manpower required. Secondly, the reduction of injuries, fewer absences and sick leave among employees.
If the electric hoist receive maintenance care, so she must have a great life. The problems are easily repaired. Make tests every 6 to 12 months and inspections conducted by a qualified engineer to ensure your safety at time of use.
