Yanmar’s Unique ∑ boom – A Breakthrough in the Concept of the Ultra Tight Turning Machine
The B7 is for users who want to dig deeper and more efficiently. It is ideal for jobs in restricted urban sites and densely built-up areas, for use in water, sewage and gas piping work and laying communications cables.
- Small jobs that had to be done by hand are mechanized now.
- The long third boom for deep and powerful left offset digging.
- The ∑ boom turns like magic in restricted sites.
- High tensile steel for superior work stability and weight reduction.
Efficiency and stability beyond your regular ultra tight turning machine.
Yanmar’s unique ViPPS and ViCTAS systems of the famous Super ViO series give work efficiency and power close to those of standard, non-ultra tight turning machines.
- ViPPS – Fast and smooth multiple job operation with Yanmar’s 3 pump hydraulic system. ViPPS has the arm preferential conflux hydraulic circuit. During multiple operation of the boom, arm, bucket and turning, the arm speed is ensured through the preferential flow of hydraulic oil to the arm circuit. The style of digging and unloading soil is smooth and efficient.
- ViCTAS – It grips a broad area of ground for higher stability. Yanmar’s ViCTAS undercarriage offers better stability without extending the machine width. The track rollers on the tipping line are installed further outwards than in conventional models to improve the sideways balance. The longer crawler ground contact enhances the longitudinal balance, so the ground is gripped well without increasing machine weight. The lifting capacity is boosted, too.
