On tracks
Although you are looking for a speedy, ergonomic solution for unloading unit goods, you may also need to consider forklift traffic.
Increase your flexibility by installing a Caljan BeltTrack telescopic boom conveyor fitted on tracks.
Lying flush in the floor, the tracks allow the boom to swing away from the door in a slewing movement - shown here - so that forklift traffic can access the door. Alternatively, you can save costs by fitting tracks parallel to the door allowing a single boom to serve multiple doors, by simply traversing along the tracks at the press of a button.
The conveyor pictured here is fitted with a portal tube light to optimise visibility inside the trailer.
