Lifting Equipment Service: How does a hoist work?

 Dongqi chain hoist  can supply many types of lifting hoists which will be operated manually, electronically, to help to raise and lower heavy loads and is usually used to transport objects from one location to a different.

This hoist device most frequently features one or multiple fixed pulleys, a moving pulley with a hook or other component for attaching loads, and a braided rope/ aluminum alloy chain between them.

Hoist components:

• Traveling Machinery: Made from a motor, gear, and brake, the traveling machinery allows for the horizontal movement of the hoist.
• Trolley: A trolley may be a support structure that the hoisting machinery is attached to. it’s composed of a load beam and end carriages.
• Rope: The rope of a hoist features strong metal wires that are laid together sort of a helix or braid.
• Hook: The hook features a clamp that connects the load to the hoist. The clamp or other locking mechanism is important to support the thing moved by the hoist.
• Controller: A radio or pendant operates the system , which directs the vertical movement of the hook also because the horizontal movement of the hoist.

How to operate a hoist work?

Operating a hoist includes knowing the load restrictions and requirements also as built-in safety features. The operator may set operating limits of a hoist, which limit movements under certain circumstances. A hoist also comes with safety features that prevent overloading a lift, limit travelling movement, or prevent all movements with an emergency stop button.

Once all regulations and requirements are set, the operator uses the controller to activate the relevant button or joystick to maneuver the hook vertically. The signals given by the operator, along side any safety devices or sensors, control the break and motor. When the hoist receives the signal, power is supplied to the motor, releasing the break. The motor drives the hoisting gear, which reduces the rotation speed and increases torque so as to lift the load.

The rope is fixed to the hoisting drum on one end and connected to the rope anchorage on the opposite . because the hoist drum rotates, the rope winds or unwinds and is guided into the right groove of the drum, allowing the hook to boost or lower. There are two ways to prevent a hoist: by releasing the up or down controls on the controller, or by activating the emergency stop button.
