The following is a detailed explanation of the function and working principle of the dual speed electric hoist (a lifting mechanism that may be included in the electric basket):

1、 Function

The dual speed electric hoist has two speed modes, usually including fast and slow. This design allows the gourd to flexibly adjust its operating speed according to different work requirements, improving work efficiency. Specifically, the fast mode is suitable for fast lifting over long distances and light loads, while the slow mode is suitable for precise control, smooth lifting over short distances or heavy loads.

2、 Working principle

The working principle of a dual speed electric hoist is mainly based on the speed regulation mechanism of the electric motor and the coordination of the transmission mechanism. The following is a detailed explanation of its working principle:

Motor speed regulation:

The electric motor of a dual speed electric hoist usually adopts a special speed regulation design, such as a dual winding or multi pole motor, to achieve different speed outputs.

By changing the power supply mode of the motor (such as changing the winding wiring or adjusting the output frequency of the frequency converter), the speed of the motor can be switched to achieve both fast and slow working modes.

Transmission mechanism:

The transmission mechanism of an electric hoist mainly includes components such as a reducer, sprocket, and chain.

The power output by the motor is reduced by the reducer and transmitted to the sprocket and chain, thereby driving the lifting mechanism of the hoist.

In a dual speed electric hoist, the transmission mechanism needs to be able to adapt to changes in motor speed to ensure smooth and reliable operation at different speeds.

Control system:

The control system of a dual speed electric hoist usually includes components such as an electrical control box, operation buttons, limit switches, etc.

The operator sends instructions to the electrical control box through the control button, and the electrical control box controls the start stop and speed regulation of the motor according to the instructions.

The limit switch is used to restrict the lifting range of the hoist and prevent it from operating beyond the safe range.

Working process:

When rapid lifting is required, the operator switches the control button to fast mode, and the motor runs at a high speed, driving the hoist to quickly rise or fall through the transmission mechanism.

When precise control or smooth lifting is required, the operator switches the control button to slow mode, and the motor runs at a lower speed to ensure that the hoist can reach the designated position smoothly and accurately.
