GENERAL INTRODUCTION 

 

This  OPERATION  MANUAL  explains  how  the  DHOLLANDIA  hydraulic  ramp  is  manufactured;  what  safety  devices  are 
incorporated in its design; and how to use the hydraulic ramp in a correct manner, that preserves the integrity of the machine over 
the intended lifetime and helps maximize the safety of the operator and any bystanders. 

 

The  MAINTENANCE  AND  REPAIR  MANUAL  (separate)  explains  how  to  maintain  and  service  the  hydraulic  ramp  in  the 
appropriate manner, maximizing the safety of the operator and any bystanders, and ensuring the reliability of the hydraulic ramp 
over the intended lifetime. 

 

The CE IDENTIFICATION AND INSPECTION LOGBOOK (separate) contains the serial number identification, the CE Declaration 
of Conformity, the Fitting Declaration to be filled out by the installer of the hydraulic ramp, and an overview of the owner’s legal 
obligations in terms of periodic testing and certification. 

 

The manuals must be kept with the  hydraulic ramp at all times, as a reference book for the operators and technical service 
personnel.

INTENDED USE 

DHOLLANDIA hydraulic ramps are designed to be fitted to commercial vehicles (commercial trucks, trailers and semi-trailers), and 
shall be used exclusively to load and unload the goods transported on the vehicle they are fitted to, within the limits of the load chart, 
in compliance with the operator instructions and safety instructions described in this manual. 

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. 

 

 

 

 

WARNING 

 

Improper use of the hydraulic ramp will put the operator and other parties at great risk of serious bodily injury and death. 
Therefore, the use of the hydraulic ramp is restricted to skilled operators only; who have been properly trained, and who know 
and understand the full contents of this manual. 

 

Unauthorized modifications to the hydraulic ramp can put the operator and other parties at great risk of serious bodily injury 
and death. Therefore, it is strictly forbidden to modify the hydraulic ramp and its safety devices in any way. 

 

Use of aftermarket or non-OEM replacement parts to repair or maintain the hydraulic ramp is strictly prohibited and may result 
in serious bodily injury or death to the operator or any bystanders. 

WARNING 

 

Improper  use  of  the  hydraulic  ramp  will  put  the  operator  and  bystanders  at  great  risk  of  serious  bodily  injury  and  death. 
Therefore, it is strictly forbidden to use the hydraulic ramp in a different way, or for different purposes than described in the 
operation manual. 

 

The hydraulic ramp must NEVER be used as an elevated work platform, to push loads, or to carry people. 

 

DHOLLANDIA disclaims liability for any personal injury and / or property damage that results from improper use.
