A Hook-lift Compactor is generally larger than a skip-lift compactor.
14-26m3 (18-34yd3) Portable Hook-Lift Compactors
To empty this type of compactor you will need a Hook-Lift Vehicle. The vehicle will remove the compactor from site, empty it of waste and return it empty.
A portable compactor is usually a benefit when a site is producing wet or contaminated waste. If the waste is dry and space is available Static Compactors can sometimes be a better option. A static compactor requires a bin which clamps on to the end of the compactor. When the bin is full it is exchanged.
