Drive system:

The VAKO covering system can be operated directly from the truck.
There should be a hydraulic pump unit with valves for actuating the cover system.
The unit can also be equipped with a radio remote control.
Both cover halves will open and close simultaneously. Separate operation is also possible.
Sometimes, the hydraulic supply to the cover system is yet to be built on the truck/trailer.


The VAKO cover system is hydraulically driven. The tractor, truck or trailer must be equipped with a hydraulic system first. Sometimes the system is provided by the manufacturer allready. You can choose for an optional powerpack as well. VAKO does supply a optional retrofit kit with all hydraulic components to equip your vehicle yourself.


The specific components used for driving the covers are:

2 hydraulic drive units with 50mm shaft completely pre-assembled.
2 overcenter valves to prevent accidents due to unforeseen movements caused by leakage.
2 restrictor valves so that both cover halves move together. They come in 2 speeds.Other hydraulic components are standard on the market. We recommend to use pipes of 12mm. These components are not included in the drive units. We can offer a optional complete kit with all suitable parts.


  • Hydraulic pressure: 180bar (min.)
  • Flow 10L / min. (min.)

Building up the system:

The entire construction can be done at VAKO’s, but also at manufacturers, distributors and customers themselves.
The cover system is tested on proper working and approved when it’s builded onto the vehicle at VAKO.
When the Drive Kit, covers and possibly the headboard are provided by VAKO, the client construct them onto the dump body and is responsible and should take care for a proper working of the covers. Work instructions and drawings are included made by VAKO engineering.
The hydraulic components are not included. We can supply it optionally, and their installation will be done by the customer. Fitting from truck or tractor to the headboard of the dumper body.
