Hooklift Lorry: Difference between revisions

The skip has a 'bar' at the front which is used for lifting and pulling the skip onto the lorry. The lorry has an arm with a 'hook' on the end that is hydraulically powered such that the arm can pivot and move over the back of the lorry for the hook to locate on the bar of the skip (hence the name 'Hooklift'. Once engaged, the arm is reversed in it motion to firstly draw the bid towards the lorry (the skip has small metal wheels at the opposite end of the skip to the bar) and then up and onto the lorry (see picture below). The arm then moves forward and the skip moves into the correct position on the lorry (with wheels on the lorry to allow the smooth movement of the skip) before being locked into place via a set of automatic fixings on the body of the lorry. The use of the wheels to roll the skip onto and off the body of the lorry is why it is often referred to as a 'Roll-on Roll-off' lorry (or 'Ro-Ro' for short).
