EH range of air operated monorail hoists from J D Neuhaus has been enhanced with added emergency lowering device. With this feature, the hoists comply with such standards as NORSOK, which specifies an emergency device for the safe lowering of loads in the event of a cut in the mains supply. The new device supplements an existing fail-safe disc brake, which is activated in the immediate event of a power failure, ensuring that suspended loads are held safely and securely at their above-floor level until mains power is made available. Company’s hoists with 25-60t capacity may be equipped with the latest safety development. This comprises an additional separate pressurized air reservoir tank (maintained at 6 bar at mains), with a purpose built hand controller incorporating two additional pushbuttons. The controller provides two-handed 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. The air reservoir, which is protected by a check valve, is topped-up during normal hoist operations, and contains sufficient air supply to complete the controlled lowering of a suspended load in the event of a loss of mains air pressure. Det Norske Veriras certification of the emergency device can be supplied where required.
