Electric drive
An electric drive converts electrical energy into mechanical energy. This makes it possible to put parts of machines in motion. The big advantage of electric motors is that they can be connected to mains power. In addition, electrically powered machines can be fitted with a battery. Tail lifts make use of an electric motor to power the hydraulic pump.
Electric drive
The electrical components are controlled by switching components.
Switching components regulate the flow of current:
- NO (normally open) switching components prevent current flow when they are not operated
- NC (normally closed) switching components allow current flow when they are not operated
Switching components provide control:
- The main power relay.
- The hydraulic valves.
- The control relay.
- Switching components control the tail lift electrically.
Electrical parts
An electrical control converts electrical energy into mechanical energy. This makes it possible to put parts of machines in motion. Haco Tail Lift Parts sells electrical parts under its own HACO label that are 100% interchangeable with the electrical parts of all brands of tail lifts. These include: battery cables, cable harnesses, cables and plugs, electric motors, kostal cables, plugs, spiral cables, trailer cables, battery terminals, flasher relays, fuse holders, fuses, mini relays, platform lights, printed circuit boards.
Mercury switch
When the angle adjustment is controlled electronically the tail lift is fitted with an inclination switch/mercury switch. Sometimes also in combination with an oil pressure switch.
The mercury switch is also used for:
- Switching on and off the manual- and foot control.
- Switching on and off the platform lights in the open position.
- Switching on and off the electric motor for the opening function.
- For safety: if the tail lift is open, the light in the cab switch is generally flashing.
Electric motor
An electric motor converts electricity to motion. The electric motor can move because the coils are placed in a magnetic field. An electromagnet (coil) produces an electromagnetic field. This field causes the rotor to turn slightly: the coil is electrically charged, and the charge is attracted or repelled in the magnetic field.
Maintenance of electrical parts
- Visually inspect the motor for damage.
- Check the plug connections and cable eyes in the power pack for corrosion and secure connection.
- Check the power supply cabling for cracks in the insulation, cable eye connections, corrosion of the fuse, and corrosion of the battery terminal clamps.
- Check the voltage at the motor and the current draw.
- Listen for any irregularity during operation of the motor (the bearings).
