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.
