The GeoMil 100 kN penetrometer pusher is mounted parallel to the long axis of the crawler and the operator has easy access to the pusher and to the tube rack to the left, hosting 20 standard sounding tubes. The high end model comes with a waterproofed operation control box providing a joystick for the soundimg contol and a swingable tube rack that can be turned by 90° allowing for a perfect working position. The basic model is operated by manual levers and the tube rack is in a fixed position. The LWC has been designed for a CPT operation with either the GeoMil analogue electrical CPT cones, mechanical cones or the Geotech cordless digital CPT system. |
| Anchoring will be performed by a hydraulic and synchronised down-force/rotation gear positioned at the rear of the rig (see right pictures). To ensure for a total reaction force of max. 100 kN up to three anchors are placed in an alignment along the long axes of the LWC. Two anchors at the front end of the adjustable sounding beam take up to 75% of the achievable reaction force. A third anchor at the rear of the LWC can be applied if necessary. Due to the paralled anchor alignment a minimum manoevering effort is necessary for placing the anchores and once cable or pipe obstacles are located in the ground anchoring can be achieved without renewed ground control. |

The Hatz silent-pack Diesel engine ensures for a low noise level so that the operator as well as the environment will suffer less from machine noises. A cardan shaft with 2 U-joints actuates the hydraulic axial piston pump incorporated in the hydraulic tank (150 litres) for less noise. |
| Four hydraulic jacks with a stroke of 500mm guarantee for a perfect horizontal levelling of the LWC and even small height differences of the ground can be compensated. While the front jacks are attached to a single foot plate and lowered simultaneously, the rear jacks can be lowered independently. For the high end model jacking is done by means of the remote control and the rear jacks can be laterally extanded, according to the chosen track width. |

Each Light Weight Crawler comes with a set of high performance proportional valves. For the high end model 11 sections of electrical valves are mounted in a manifold block. 2 sections for penetromter pusher, 3 sections for jacking, 2 sections for anchoring, 2 sections for track speed and 2 sections for extanding the jacks and tracks. The basic model comes with 8 sections of mechaniacl proportional valves. 2 sections for the penetrometer pusher, 3 sections for jacking, 2 sections for anchoring and 1 section for track speed. |
