The CPT crawler-truck is a CPT penetrometer rig based on a truck-chassis provided with a crawler undercarriage. The crawler-truck has been designed to execute soil mechanical research based on static Cone Penetration Testing (CPT) techniques in an efficient manner. By means of the penetrometer pusher, installed in the centre of gravity of the CPT crawler-truck, either an electrical or mechanical probe (called a cone) is pushed into the ground and the mechanical resistance and friction of the soil is recorded. The CPT crawler-truck itself has a relatively high own weight and serves as counterweight to provide the required penetrative force.
