30 kN Electric Slipway Hauling Winch
30 kN Electric Slipway Hauling Winch
A 30 kN electric slipway hauling winch built in Yatala to replace outdated machinery on a commercial slipway, hauling a 250 kN rolling load up a 5 degree incline on a single line, with variable speed and single-phase power.
Slipway Upgrade Project Overview
A custom-built 30 kN electric hauling winch replacing outdated slipway machinery
A one-off 30 kN electric hauling winch designed to replace outdated machinery on a commercial slipway. The old winch had reached the end of its life and the yard needed a modern, certified replacement that would fit the existing winch house and haul its heaviest vessels. The new winch pulls 30 kN on a single line, which over a rolling load on the slipway incline hauls a 250 kN vessel and cradle up a 5 degree grade. It is variable speed, powered from a single-phase supply, and carries 150 m of rope. The winch, control cabinet and pendant were engineered, built and tested at our Yatala, Queensland workshop.

Operational & Technical Breakdown
An in-depth look at the 30 kN electric slipway hauling winch's performance and technical capabilities
ACW started from the slipway itself: a 250 kN rolling load on a 5 degree incline, with cradle friction, resolves to a line pull well within 30 kN, so the winch was sized with margin rather than oversized. The drum stores 150 m of rope for the full slipway length, mounted in a fabricated marine steel frame with a gearbox and single-phase motor and a footprint arranged to bolt down where the old winch stood.
The control cabinet carries a variable speed drive and a panel with local and remote selection, in and out controls and a speed dial, plus an emergency stop, so the operator can haul from the winch house or from a remote position with a view of the cradle. A spring-applied brake holds the vessel on the grade whenever the winch stops. The complete system was load tested at Yatala with certificates supplied for the yard.
Other Winch Applications
Versatile winching solutions across multiple industries.
Beyond marine, replacement winch packages with modern variable speed controls suit any site running ageing hauling machinery on ramps, inclines and rail tracks.
Hauling survey and maintenance boats up ramps at hydro dams and pumped storage schemes – single-phase electric winches with variable speed for controlled recovery.
Launching and recovering work boats and pontoons on tailings dams and mine water storages – compact electric hauling winches that run off site power.
Project Conclusion
The 30 kN electric slipway hauling winch replaced outdated machinery with a right-sized, certified winch and modern controls in the same winch house. Designed, built and tested in Yatala by Australian Certified Winches.
Like every winch we build, it was designed to AS 1418, the Australian Standard for cranes, hoists and winches, and signed off by our RPEQ-registered engineers before load testing in Yatala.

Frequently Asked Questions
Common questions about replacing an existing slipway winch.
How was the winch size worked out?
From the slipway, not the old winch. ACW took the heaviest vessel and cradle, about 250 kN, the 5 degree grade and the rolling friction of the cradle, and calculated the line pull needed. 30 kN on a single line covers it with margin.
Will a new winch fit the existing winch house?
Yes. The frame footprint, rope exit height and cabinet position were designed around the existing winch house so the new machine bolted down where the old one stood, with minimal civil work.
Why single-phase power?
The slipway only had single-phase supply at the winch house. The motor and variable speed drive were chosen to deliver the required pull from that supply, avoiding the cost of running three-phase cabling.
How is the haul controlled?
A variable speed drive gives smooth starts and adjustable speed, and the panel offers local operation at the cabinet or remote operation from a station with a view of the cradle. A spring-applied brake holds the load whenever the winch stops.
Is the replacement winch certified?
Yes. The winch was designed and load tested to AS 1418 at Yatala and delivered with test certificates and RPEQ sign-off, giving the yard current compliance documentation that the old machine lacked.
Upgrading a Slipway Winch?
Tell us the vessel weight, the slipway grade and the power you have on site. Our RPEQ engineers will size a certified replacement slipway winch for it.
