A purpose built drill rig unit can be fitted to a mobile two-wheel trailer to form a specialist trailer drilling rig capable of being towed behind a van or car. These drilling rigs are used for specialist operations such as core sampling in roads, drilling and installation of motorway barriers and runway lights etc. They are generally self-contained units, with their own water tank and power source which is driven by an engine, mounted on the trailer chassis.
