The GTR 780 is the ideal entry into the world of crawler-mounted probing rigs. It can be operated intuitively by a single person and stands out благодаря its compact and lightweight design. The unit is designed for dynamic probing in accordance with DIN ISO 22476-2 and DIN ISO 22476-3 (formerly DIN 4094), and enables the execution of light (DPL), medium (DPM), heavy (DPH), and super heavy (DPSH / SPT) tests through simple on-site adjustment of the hammer unit.
The machine is also ideally suited for core penetration testing. Depending on the application, either the hammer unit or an optional hydraulic hammer can be used, ensuring fast and comfortable operation.
The machine is mounted on a self-propelled rubber track undercarriage, providing excellent off-road capability. The mast can be adjusted in six directions, even on uneven terrain, and precisely aligned vertically using an integrated level. This ensures accurate vertical operation at all times, regardless of the machine’s position.
The system is fully hydraulic and equipped with an integrated automatic extraction system. For easy and compact transport, the mast is foldable, and the low overall weight provides an additional advantage.
The machine is equipped with storage compartments for rods and tools, as well as mounts for the hydraulic extraction cylinder, base plate, and clamps. This eliminates the need to manually carry heavy drilling equipment from one test point to another, as all necessary equipment is stored directly on the machine.
