Working Principle of Electric Hoist

An electric hoist is a device used to lift and move heavy loads. It uses an electric motor to power the gear and pulley system that allows the crane to lift and lower heavy loads. The electric hoist works by converting electrical energy into mechanical energy, which is used to lift and move heavy loads.

 
 


The following are the main components of an electric hoist and how they work together:

  • Electric motor: The electric motor provides the power needed to drive the hoist's gears and pulleys. It converts electrical energy into mechanical energy to lift the load.
  • Gears: The gears in an electric hoist help transfer power from the motor to the reel. They increase the torque and reduce the speed of the motor.
  • Lifting drum: The lifting drum is a cylindrical spool around which the lifting cable is wrapped. As the reel turns, the cable winds or unwinds, depending on the direction of the motor.
  • Lifting cable: The lifting cable is the rope or wire that is wrapped around the lifting drum. It is used to lift and lower the load.
  • Pulleys: Pulleys are used to change the direction of the lifting cable. They help guide the cable and prevent it from becoming tangled.
  • Control System: The control system allows the operator to control the movement of the hoist. It includes buttons or switches for starting, stopping, lifting, and lowering the load.


When the operator activates the control system, the motor begins to turn the gears. The gears increase the torque and reduce the speed of the motor, allowing it to lift heavy loads. As the motor turns the lifting drum, the lifting cable wraps around it, pulling the load upward. To reduce the load, the motor reverses direction and the cable is released from the drum.

Precautions for Using Electric Hoist

Electric hoists make it easier to lift and move heavy loads. But, they can also be dangerous if used improperly. Here are some things to keep in mind when using electric hoists:

  • Follow the manufacturer's instructions:
    Before using an electric hoist, read the instructions carefully to make sure you understand how to operate it safely.
  • Inspect the hoist before use:
    Inspect the hoist for any signs of damage before use. Make sure all components are in good working order, including the cables, hook, and control system.
  • Do not overload:
    Electric hoists are designed to lift specific weights. Make sure you know the load rating of the hoist and never exceed it.
  • Use proper rigging:
    Use proper hoisting techniques when securing the load to the hoist. Make sure the load is securely fastened and balanced.
  • Needs to be attended to:
    Always keep an eye on the load when it is being lifted or moved. Never leave it unattended.
  • Keep the area clear:
    Keep the area around the hoist clear of people and other objects. Make sure there is enough room for the load to move safely.
  • Use proper protective equipment:
    Wear proper protective equipment, such as gloves and helmets, when operating the electric hoist.
  • Regular maintenance:
    Inspect and maintain the hoist regularly to ensure it is in good working order.

Using lifting equipment requires caution, attention to detail, and proper training. By following these precautions, you can use your electric hoist safely and effectively.

Common Electric Hoists and Different Applications

  1. Chain hoists: Chain hoists are the most common type of electric hoist. They use a chain to lift and move heavy loads. They are suitable for a wide range of applications, from construction and manufacturing to warehousing and logistics.
  2. Wire rope hoists: Wire rope hoists use a wire rope instead of a chain to lift and move heavy loads. They are often used in industrial applications where heavy loads need to be lifted to a great height, such as in the construction of tall buildings.
  3. Explosion-proof hoists: Explosion-proof hoists are designed for use in hazardous environments where there is a risk of explosion. They are often used in chemical plants, refineries, and other industrial settings where explosive gases or vapors may be present.


Why Custom a Crane Solution?

At Yuantai, we know that there is no "one size fits all" in the lifting field. Universal cranes are suitable for general factories, warehouses, etc. Besides, different applications have different needs for cranes. For example, steel industries often lift steel plates, so need electromagnetic cranes. Ports and docks often need to load ore, gravel, and other bulk goods, so need to grab bucket cranes. Chemical dangerous places often need to carry flammable and explosive materials, so need explosion proof cranes.

So, we provide customized cranes according to the special needs of our customers. Custom crane solutions offer many benefits in a variety of applications:

  • Improve efficiency: Cranes can use automatic controls, and special accessories to improve efficiency.
  • Break space constraints: In limited spaces, standard cranes may not fit due to their size. Custom cranes can be designed as compact or lightweight cranes.
  • Cost savings: Customized cranes can lead to long-term cost savings. Customized crane solutions ensure crane's performance is all necessary for your business.
