Dry feed (jacks)

Veldman Techniek is your supplier for various types and sizes of dry feed jacks.

If you want to fill your feed troughs, feeding stations, wheelbarrow or feed cart in a simple way, you can use a jacks system. These can be supplied as a flex jack, this is a jack with plastic jack tubes and as a rigid jack, these are steel tubes and screws.

Rigid jacks / screw conveyors

In addition to flex jacks, we can also supply transport screws. These consist of a steel tube containing a screw conveyor.

The standard dimensions of these transport screws are:

The length of 1 part of the screw is 6 meters. The jack can also be made shorter or longer at your request. The rigid jack can be shortened if it is 6 meters too long and can be made longer with the help of connecting pieces.
