Hoist & Winch designs bespoke electric winch system for ‘wet room’

The company wanted a bespoke electric-powered winch lifting system to raise and lower large vinyl-type sheets in a purpose-built ‘wet area’. With no challenge too demanding, Hoist & Winch stepped up to the task.

At the heart of the Hoist & Winch system are four floor-mounted Yale RPE 400V three-phase winches offering 150kg swl (safe working load) and 20 Pfaff roof-mounted diverter pulleys coupled to four 12m long tubular spreader beams. Each winch raises and lowers one of the 12 m long spreader beams which attach to the vinyl sheet via load-bearing karabiner clips. Each vinyl sheet weighs approximately 60kg.

The innovative winch system raises the vinyl sheets safely and in a level position. This capability permits easy drying of the vinyl sheets after pressure washing, a process that removes any unwanted residual substances from the most recent hire job.

Each winch sits in purpose-manufactured mounting frames secured to the floor using four Hilti expansion anchors. The frame design allows orientation of the winch rope pay out at 90° to the first diverter pulley.

Ultimately, the system designed by Hoist & Winch Ltd significantly improves the whole operation to facilitate a quicker and far less labour-intensive turnaround of the vinyl sheets during busy periods of hire.

The company also provided installation (using electric scissor lifts for working at height) over a seven-day period and subsequent commissioning. Further responsibilities included all wiring and load testing of the whole system. Once complete, Hoist & Winch Ltd issued a LOLER (Lifting Operations and Lifting Equipment Regulations) ‘Thorough Examination’ report.

To ensure smooth handover, Hoist & Winch Ltd undertook comprehensive operator training covering: overview of the winch units and main components; operating controls and features; periodic checks and lubrication; annual inspection, service and certification requirements; and practical operation by each operator.

Hoist & Winch Ltd Director Andy Allen says: “This project set out a number of important stipulations to which we had to respond comprehensively and efficiently. A successful outcome that meets with the project’s ambitions, delivered on-time and on-budget, is our primary aim. Once again our professional and experienced team of engineers here at Hoist & Winch Ltd came up with a safe, reliable, high-performance solution to the satisfaction of our valued customer.”
