The wheeled sampling and profiling rigs are primarily used for dynamic probing, an application where a continuous density profile of the soil is obtained. However these rigs can also be used for soil sampling where the fixed cone is replaced by sampling tubes.
These rigs are very maneuverable and can access almost any location including up and down flights of stairs, through doorways and up and down slopes. The rig is light enough to be carried over obstacles should the need arise. In order to maintain the maneuverability of the equipment all of the associated tools such as the jacking system are hand portable.
