3-Wire Forward and Reverse Mini Electric Hoist Remote Connection

By Nazakat Ali – Watt Vission

The mini hoist’s control system is simple and effective, using a remote with only three wires to control the forward, reverse, and stop functions. Below is a detailed guide on the key components found inside the remote and how they work together to control the hoist.

Key Components Inside the Remote:

1. Forward Button (Black Arrow):
   • This button controls the forward motion of the hoist, allowing it to lift or pull. When pressed, it activates the wiring connection that supplies power to the motor in the forward direction.
2. Reverse Button (Orange Arrow):
   • This button controls the reverse motion of the hoist, allowing it to lower or release the load. When pressed, it activates a different wiring connection that powers the motor to spin in reverse.
3. Emergency Stop Button (Red Button):
   • The emergency stop button is a safety feature built into the remote. When pressed, it cuts off power to the hoist motor, instantly stopping the movement in both directions.
4. Internal Switch Mechanism:
   • Inside the remote, there is a switching mechanism that directs the electrical flow to the motor. Depending on whether the forward or reverse button is pressed, the switch changes the wiring connection to move the hoist in the desired direction.
5. Wiring Connections:
   • The remote contains three main wires:
     • Wire 1: Connects to the forward control circuit for lifting.
     • Wire 2: Connects to the reverse control circuit for lowering.
     • Wire 3: Links to the emergency stop function, ensuring immediate power cut-off when required.

Wiring Process:

• Forward Motion: Press the black arrow button, and the remote sends power to the motor to move the hoist in the forward (lifting) direction.
• Reverse Motion: Press the orange arrow button, and the remote activates the reverse circuit, making the hoist move backward (lowering).
• Emergency Stop: Press the red emergency stop button, which cuts the power supply and stops all hoist operations instantly.

Capacitor (Outside the Remote):

• The remote connects to a capacitor (80 µF), which helps give an extra boost to the motor during startup, making the motor run smoothly and efficiently.
