1. Confirm the application: power up, gravity down

The Auto hoist power unit is designed only for auto hoists that use a power-up, gravity-down function:

• Starting the motor lifts the machine.
• Lowering is controlled by solenoid release valves.
• Each solenoid valve gives a separate lowering speed.

When it does not apply: If your equipment needs powered movement in both directions, or extra functions such as side-to-side swing, this unit is not the right choice. For example, the company's Snowplow power units are a separate product. They are built for trucks fitted with different types of skis and provide lifting plus left-right swing, with different loops and valves available as options. Choose the product that matches the motion your machine actually needs.

2. Check the listed specification values

The published Auto hoist power unit table shows these values:

The published table does not make clear exactly how these values combine into each model. Before you order, ask the supplier to confirm the full model configuration (voltage, motor power, displacement, relief pressure, tank and valve voltage) for your project.

If you need a different flow, pump pressure, motor power or other system parameter, the product notes point to the model descriptions of the company's other power unit series. Treat any value outside the listed table as something to confirm, not something to assume.

3. Match the duty cycle to your lift usage

The unit is rated for S3 duty: 30 seconds on, 270 seconds off. This suits intermittent lifting. If your application needs long or frequent continuous running, discuss it with the supplier before selecting this unit.

4. Plan for installation and oil requirements

The published notes list these requirements:

• Clean all related hydraulic parts before mounting the power unit.
• Mount the power unit horizontally.
• Use clean hydraulic oil with no impurities and a viscosity of 15-68 cSt. N46 hydraulic oil is recommended.
• Change the oil after the first 100 hours of running, then every 3000 hours.

If your installation space only allows a non-horizontal position, this is a limit to raise early in the selection.

5. Specify options when ordering

Manual emergency oil release is available if required, but you must ask for it when you place the order. Decide early whether your hoist design needs it.

Buyer checklist

1. Does the lift work as power up, gravity down, with solenoid-controlled lowering?
2. Which motor voltage (220V or 24V) does your power supply support?
3. Have you confirmed the full model configuration from the listed values?
4. Does your usage fit S3 duty (30 s on, 270 s off)?
5. Can the unit be mounted horizontally, and can you supply clean 15-68 cSt oil (N46 recommended)?
6. Do you need manual emergency oil release written into the order?
7. Have you confirmed price, lead time and any required certifications directly with the auto lift power unit manufacturer?

Working through these points first helps procurement teams and distributors compare Auto hoist power units based on how well they fit the application, not on catalogue numbers alone.
