The MD1 electric hoist is a dual speed wire rope electric hoist, and its dual speed operation mechanism mainly relies on the coordinated work of the dual electric units. The following is a detailed analysis of the dual speed operation of MD1 electric hoist:

Dual electric unit composition

The dual electric unit of MD1 electric hoist consists of the following parts:

Main lifting motor: responsible for the main lifting power of the electric hoist.

Slow lifting motor: provides lifting power for the electric hoist in slow mode.

Slow drive device: used to drive the conical rotor of the main lifting motor to rotate in slow mode, achieving slow lifting.

Dual speed operation principle

Quick mode:

When the main lifting motor is working, the slow lifting motor is in a non working state (i.e. not powered, in a braking state), and the slow driving device remains stationary.

At this time, the electric hoist runs quickly under the drive of the main lifting motor, suitable for scenarios where heavy objects need to be lifted quickly.

Slow mode:

When slow lifting of heavy objects is required, the slow lifting motor starts working.

The slow lift motor drives the conical rotor of the main lift motor to rotate through a slow drive device. At this time, the main lifting motor is not powered and is in a braking state to avoid interference with slow lifting.

Driven by a slow lifting motor, the electric hoist runs at a slower speed, suitable for scenarios that require precise control of lifting speed, such as precise loading and unloading, sandbox stacking, machine tool maintenance, etc.

Advantages and Applications

The dual speed design of MD1 electric hoist has the following advantages:

Improving work efficiency: The fast mode is suitable for a large number of fast lifting operations, while the slow mode is suitable for work scenarios that require precise control, thereby improving overall work efficiency.

Enhanced safety: The slow mode reduces the lifting speed, which helps operators better control heavy objects during the lifting process and reduces the possibility of accidents.

The MD1 electric hoist is widely used in factories, mines, ports, warehouses, cargo storage areas, and shops, and is one of the important equipment for improving work efficiency and working conditions.
