Compact Lift Tables

Introduction

This power unit is designed for lift tables and integrates a high-pressure gear pump, AC motor, multifunctional manifold, valves and tank. Starting the motor raises the platform. Lowering is activated by the solenoid valve, with lowering speed regulated by the pressure-compensated flow control valve.

Precautions

  1. S3 intermittent duty: 1 minute on and 9 minutes off. Continuous operation is not permitted.
  2. Clean all hydraulic components, cylinders, hoses and fittings before installing the power unit.
  3. Use clean hydraulic oil free of impurities, with a viscosity of 15-68 cSt. N46 hydraulic oil is recommended.
  4. Change the hydraulic oil after the first 100 operating hours and every 3,000 hours thereafter.
  5. Mount the power unit horizontally.
