The HiSpec Demountable range covers both a demountable Kompactor and Demountable Vacuum Tanker which can both be used with the same chassis and running gear. Mounting or demounting is quick and simple via a hydraulic sprung draw-bar and twist locks. This offers the user a unique opportunity in transforming an already versatile vehicle into a multi-purpose, multi-functional trailer

Reduced Maintenance Costs

The demountable Kompactor provides significant savings through sharing the cost of the running gear and chassis between multiple platforms. This also reduces maintenance costs over the cost of maintaining two separate units.
