Supplement Fail-Safe Hoist Brakes

Supplement Fail-Safe Hoist Brakes

J D Neuhaus offers 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. This new 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 made available.

JDN monorail hoists with lift capacities from 25 to 60 tons can now be equipped with this device which comprises an additional separate pressurized 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. One button switches between normal and emergency lowering operations. The second button activates the integrated safety brake enabling the safe controlled lowering of a deadweight load.
