Undercarriages –  

An undercarriage is used to give additional traction for machines such as bulldozers. They also give superior all-terrain capability and are used extensively on excavators. Undercarriages with have wide pads give lower pressure and cause less ground disturbance and prevent machines from sinking on soft ground. Sigma also supply undercarriage sets for HitachiKomatsu and JCB equipment. Please contact the Sigma Plantfinder team today for more details.

Rippers – 

Rippers are often fitted to the rear of motor graders and heavy dozers, to loosen the surface ready for the next machine pass. Rippers consist of a steel frame with one (single shank ripper) or several (multi shank ripper) teeth which fit into the frame. The frame can then be lowered hydraulically to push the teeth into the ground. The machine weight and traction ensures that the ripper can pull through the ground, and rip out trees, roots, rocks and other obstacles.
Machines are often not fitted with rippers when new, and for applications later in life one needs to be fitted. Sigma can help with both new and used rippers, we have suppliers who stock and build both new and used equipment.
Ripper teeth and the ripper cutting edges are wearing parts, and can wear and fracture due to the high stress on the teeth. For this reason, the ripper teeth are replaceable, and can be easily replaced.
