Single Drum Winches (Models WS250, WS400 and WS500)

HyQuest Solutions’ stream gauging winches are hand-operated single drum winches capable of handling gauging weights using a winch board or bridge crane (up to 70 kg (154 lb) with HyQuest Solutions’ 4 wheel bridge crane 4WBC). The winches are designed for ease of operation and serviceability in the field: robust, compact, portable, light-weight, and handled easily and safely by one person. They can be deployed from boats or bridges.

Special attention is paid to safety: An automatic Weston Brake locks the drum if the handle is released. This holds the load in any position - for safe and smooth sounding operation.

HyQuest Solutions’ winches are equipped with Amergraph cables. The special construction of Amergraph cables combines two purposes: They permit the suspension in the stream of the current meter and heavy Columbus weights and at the same time they are the medium for carrying the meter signals to a counting device.

The winches’ depth counters register in centimetres and are protected within the frame.

Use with current meter

Some elaborate features support current metering: A silver-plated slip ring conducts the signal from the sounding drum to the current meter counter. The counter can be installed at the winch itself, i.e. close to the winch operator instead of deep in the water at the current meter. The single layer of the signal cable on the drum prevents damage of the internal conductor and premature replacement.
