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 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). | The skip has a 'bar' at the front which is used for lifting and pulling the skip onto the lorry.

If the lorry is moving a skip with no lid or top (an open bin/skip) | If the lorry is moving a skip with no lid or top (an open bin/skip) which risks material blowing away during transit, there is a separate automatic 'sheeting system' operated via a separately driven arm that unrolls a sheet of fabric over the container from front to back. | ||
During tipping the container doors are opened at the rear manually and the sheeting system is rolled back (if used), and the skip is fixed at the rear whilst the lifting arm then pushes the skip upwards to facilitate the material in the skip sliding out. | During tipping the container doors are opened at the rear manually and the sheeting system is rolled back (if used), and the skip is fixed at the rear whilst the lifting arm then pushes the skip upwards to facilitate the material in the skip sliding out. | ||
