Hammerless drain valve cuts vibration
October 1st 2007 The McKenna hammerless
drain valve from Alcoa World
Alumina Australia was
awarded 'Highly Commended'
in Western Australia's
Chamber of Minerals &
Energy Occupational Safety
and Health Innovations
awards.
Based on the Pneutorque
PTM-52 pneumatic torque
wrench (torque gun) from
Norbar Torque Tools, the
valve is a tool that makes
the task of opening refinery
drain valves easier and safer
at Alcoa World Alumina
Australia's mines and
refinery operations.
The torque gun runs a
couple of gears that turn a
larger gear that operates the
valve. In effect, a simple
push of the trigger replaces
the need for repetitive
hammering to get valves to
open and close.
Vibration levels of less
than 1.5m/s2 mean the
operator can use the tools
for extended periods with
negligible risk of hand-arm
related health issues. Sound
levels are less than 85dB(A)
when under load. More articles from Norbar Torque Tools Limited: |
