RUBAG standard equipment

• Design: Neither the counterweight nor the parts in front of the uppercarriage protrude beyond the track width. As a true short-tail excavator, the B7 Sigma has an extremely small swing radius.
• Undercarriage: Maximum stability and exceptional lifting capacity thanks to the VICTAS® system. Overall width 2270 mm.
• Boom: Adjustable boom with dipper 1680 mm
• Hydraulics: The B7 Sigma-6 is equipped with a hydraulic circuit with total power control consisting of three variable axial piston pumps and a distributor with a wide range of combinations. The pumps activate automatically depending on the work to be carried out and are user-friendly. On the one hand, the working speed can be increased by summing up the pump delivery rates and, on the other hand, the system functions smoothly even when driving and can carry out all movements simultaneously
