Boarding axle power unit

This boarding axle power unit is specially designed for fixed boarding ramps and integrates a high-pressure gear pump, an AC motor center valve block, a cartridge valve and an oil tank.The motor, pump, valve, oil tank, etc. in the design are closely matched, making the operation more stable and safe.

Start the motor to realize the rise of the main board. When the pressure of the main board reaches the design pressure of the sequence valve, open the lip plate. The lowering of the main board and lip is controlled by self-weight. The descending speed of the main board can be adjusted to make the descending speed within a reliable range. There are 0.75- 1.5kW optional motors, 220-380v optional voltages, and iron and plastic oil tanks to choose from.

SPECIAL FEATURES INCLUDE:
- Sequential valve set pressure control to ensure that the lip plate will automatically open only after the main board reaches the set pressure.
- Weight-controlled descent simplifies the control system and reduces energy consumption.
- Adjustable main board descent speed ensures safety and reliability during descent and avoids excessive speed or instability.
- Solenoid valve function allows the main board and lip plate to stop at any position, enhancing the flexibility of operation.
These designs take into account different practical needs and are a very flexible and comprehensive hydraulic unit. The boarding axle power unit provides multiple motor power options (0.75-1.5kW), and the voltage can be selected from 220V or 380V. For the oil tank, you can also choose iron or plastic tanks to adapt to different working environments.

SPECIAL NOTES

The power unit is S3 working system and can not operate continuously. It starts in 10 seconds and stops in 90 seconds.

Before installation, ensure that hydraulic components such as the oil cylinder, oil pipe, and joint are free of impurities.

The viscosity of hydraulic oil shall be 15- 68 st. No.46 anti-wear hydraulic oil is recommended in summer, and No.32 low temperature hydraulic oil is recommended in winter.

After starting the operating system for the first time, check whether the oil in the oil tank is sufficient, generally 2 / 3 of the oil tank.

After the system is used for the first 100 hours, the hydraulic oil shall be replaced, and then the hydraulic oil shall be replaced every 3000 hours.
