Safe load lowering November 1st 2011 J D Neuhaus has introduced an
emergency lowering device for its EH
range of air operated monorail hoists.
With this feature JDN complies with
standards such as NORSOK,
specifying an emergency device for
safe lowering of loads in the event of
a cut in the main power supply.
The device supplements an
existing fail-safe disc brake, which is
activated in the immediate event of a
mains power failure, ensuring that
suspended loads are held safely and
securely at their above-floor level
until mains power is again available.
JDN monorail hoists with lift
capacities from 25 to 60t can now be
equipped with the latest safety
development. This comprises an
additional separate pressurised air
reservoir tank (maintained at a
mains air pressure of normally 6
bar), with a purpose-built hand
controller that gives positive twohanded
lowering control, while
eliminating the potential for
unintended load movement. More articles from J.D.Neuhaus Limited: |
