Electric Hoists are a type of lifting equipment that is used for lifting, lowering, and moving heavy and large objects. The main types of electric hoists are Electric Chain Hoists and the Electric wire Rope Hoist. There are always newer designs and technological advances in progress and are ones to look out for.
Thanks to their flexibility and versatility they are able to adapt to many lifting operations. While onsite the Electrical Hoists may be used as standalone equipment such as when it is anchored to an existing structure or as part of a lifting system such as with a trolley on a lifting gantry or Jib crane perhaps. The type of hoist will affect the travel speed and lifting speed of the electronic hoist and therefore, will influence the production rate and turnaround time of the operation.
Electric chain Hoists must be compatible with the beams of the lifting system’s structural frame as well as the electrical hoist. The Trolley is a vital part of the production process because they are responsible for transporting the Electric Hoist across the length of the beam. There are various types of Electric Hoist Trolleys, such as:
· The Push Trolley
· Geared Trolley
· Electric Travel Trolley
The Electric Hoist comes with lifting regulations that must be observed to uphold safety. These regulations are based around their rated capacity, working load, and duty cycle which are the critical specifications of Electrical Hoists.
Many Electric Hoists have built-in safety features, and the hooks will have catches for safety so the lead will not become disengaged. There are clutch systems on most electrical hoists which slip at a pre-set torque, this prevents the device from overloading which can become very dangerous.
Electrical Hoists are made with a switch mechanism, this is where the chain will mechanically engage when an overload occurs. New Electric Hoists will come with a safety cut-out switch for emergencies, these are extremely important for safety reasons.
