Boomer news

Boomer L2D was introduced in Indian Underground Civil Engineering in 1999. Since its inception, it has been a workhorse for tunnelers in India, Bhutan and Nepal. Contractors has reaped enormous benefits on account of dramatic increase in productivity, mainly due to faster rockdrill COP1838 (18 kW) backed up by 75kW power packs generating 190 cc/rev. This giant leap in power in twin boom one service platform Drill Jumbo, Boomer L2D enabled us to develop features gradually complying with NATM and NTM tunnelling methods
