  • Page 5: General Introduction

    Except for model DH-AR4*, which is also suitable for the use at loading docks, DHOLLANDIA hydraulic ramps should be used exclusively to transfer wheeled equipment or machinery from the ground to the vehicle floor or vice versa. This means the platform, its outboard platform edge and mechanical support legs and hydraulic stabilising legs MUST be in firm contact with the ground.

  • Page 6: Identification

    5 IDENTIFICATION  Every DHOLLANDIA hydraulic ramp is identified by and labelled with a unique 8-digit serial number (with or without a space between the first and last 4 digits). Use this number for any inquiry on a particular hydraulic ramp, or when ordering replacement parts.

  • Page 7: Description And Hydraulic Ramp Terminology

    GENERAL  DHOLLANDIA hydraulic ramps are developed and manufactured using state-of-the-art technology, high quality materials and components and highly skilled workmanship. They comply with the European CE safety regulations mentioned in the Declaration of Conformity issued with each lift (unless agreed otherwise for hydraulic ramps exported outside of CE region).
