Demonstrating a Marine Mooring Winch with the Buyer's Own Rope
A buyer should require a demonstration using their actual mooring rope, then verify line pull, line speed, and drum capacity against the reference values in the brief.
Ask the supplier to demonstrate the marine mooring winch with your own mooring rope rather than a sample line. Rope construction, diameter, and condition affect how the line spools and grips, so a demonstration on the buyer's material is the most useful test of whether the winch suits the material handling duty.
In the request for quotation, state the rope you will use and ask how the demonstration will be run. The brief lists reference values of 100 kN rated line pull, rated line speed of at least 15 m/min, drum capacity of 200 m of 30 mm diameter rope, and a 45 kW hydraulic motor. Treat these as catalog reference values, not as promises for the supplied model, and ask the supplier to confirm the figures for the configuration offered.
During the demonstration, watch how the rope winds onto the drum and whether it seats evenly. Ask what line pull and speed are measured, and at what rope layer, since drum build-up can change both. Agree in advance how the acceptance test will record pull, speed, and spooling with your rope.
Before requesting a quote, confirm with the supplier that the demonstration will use your actual rope, which reference values apply to the offered model, and how the acceptance test will be witnessed and recorded.
