Conceived by Hoist & Winch, one of the UK's leading lifting equipment companies, a 400 V three-phase Haacon wire rope winch providing a swl (safe working load) of 1,500 kg sits at the heart of this innovative solution. The advanced winch offers a special triple rope lead-off design that raises and lowers the export chute via one vertically and two horizontally orientated diverter pulleys. A purpose-made frame and bolted connections facilitate mounting of the winch to the steel floor, ensuring level rope pay-off from the winch drum to the three diverter pulleys serving the system.
The final wire rope connection to the export chute is via adjustable turn-buckle jacking screws and swivelling eye bolts, a design that not only provides accurate chute levelling adjustment, but also extends the service life of the wire rope by eliminating any twisting action.
Winch control arrives courtesy of a switchgear enclosure and a two-button, single-speed, hard-wired pendant control station located remotely in an environmentally protected operating cubicle. Environmental protection is vital due to operating temperatures of over 40°C in summer months, as well as excessive dust in the atmosphere and surrounding work areas.
The new winch system, which replaces an original obsolete solution that had reached the end of its service life, offers a number of further beneficial features to the customer, many relating to safety. For instance, the winch has a pressure roller to ensure secure retention of the wire rope on the drum. This capability is particularly important in the event of a slack wire rope, which might occur due to accidental over-lowering of the chute on to the HGV bed, for example.
