Be let down gently by J D Neuhaus
November 1st 2011 As part of an ongoing safety
evaluation for its products,
J D Neuhaus has introduced
an emergency lowering device
for its EH range of air
operated monorail hoists.
With this feature JDN
complies with the leading
standards like NORSOK,
specifying an emergency
device for the safe lowering of
loads in the event of a cut in
the main power supply.
The new device
supplements an existing failsafe
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 made 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
incorporating two additional
pushbuttons.
The controller provides
positive two-handed lowering
control, while eliminating the
potential for unintended load
movement. More articles from J.D.Neuhaus Limited: |
