As these one-piece machines are also easy
to assemble and disassemble, service is
expedited, thus maximizing uptime.
Operators have full control thanks to the
two-step “softstart” trigger which enables
them to start a cut with surgical precision,
allowing for seamless operation even in
difficult working conditions.
High vibration and noise levels are
leading causes of operator fatigue which in
turn, increases the risk of injury and curbs
productivity.
The company introduced a hand
and arm protection system (HAPS) to
substantially reduce vibration levels on
our SRD pneumatic handheld tool range.
Furthermore, the tool’s piston switches on
aircushions on both ends of the cylinder,
thereby almost fully eliminating metal-to-
metal contact when working off-load and
subsequently further shrinking vibration
as well as reducing wear. This substantial
reduction in vibration makes it possible to
extend working hours up to six-fold. The
vibration levels of the new generation SRD
25 rock drill is 50% lower compared to its
predecessor.
Atlas Copco has also diminished the
noise levels of the SRD tools by up to 75%
with the development of the wear-resistant
polyurethane silencer. Putting this into
perspective, this equates to a 2 dB reduction
in noise which can make a substantial
difference, especially when several drills are
operating simultaneously.
Taking further cognisance of operators’
health, Atlas Copco has developed a
pneumatic dust collector for the efficient
removal, directly at the source, of silica
