GearTopper November: Winches

GearTopper: Winches

In this monthly recurring column we would like to put a transmission or related product into the spotlight, our GearTopper. In this way, we like to share our product knowledge with our readers. We are looking forward to Offshore Energy 2022 later this month and that's why we focus on winches in this edition.

Winches are made to move an object by pulling on a rope which is spooled on the winch drum. Basically a winch exists of a frame, drum, rope and mostly a transmission. Of course there are winches that have hundreds of parts to make all required options possible, but they can also be very small and simple, even manually driven. The size of a single winch can vary from a pulling load of less than 100kg up to hundreds of tons. They can be driven manually, by hydraulic motor, electric motor, pneumatic motor or combustion motor. Mostly these motors drive a transmission to decrease the motor speed and increase the motor torque to reach the required line pull.

"The options and possibilities with Dinamic Oil winches are endless"

​Depending on the line pull, numbers of rope layers, application and customer wishes, the drum of a winch can be smooth, grooved or even made with Lebus grooves. The frames of smaller winches are both welded or bolted but for the big winches the frames are almost all welded. Options on winches seem more or less unlimited but common ones are pressure roller, limit switch, encoder, spooling device, load measurement system, double brake etc.

Winches are used for many different applications for hoisting and pulling and depending on the application the design rules, certifications or classifications can be different. Herewith a short list of common winches which is only a small part of all types of winches ever build: Main hoist winch, Boom winch, Tugger winch, Mooring winch, Auxiliary winch, Umbilical winch, Spud pole winch, A&R winch, Traction winch, Anchor winch, Capstan winch, Ladder winch, etc.

Aandrijf Technisch Buro supplies many different kind of winches, the relative small and more standard winches are mostly made by our partner Dinamic Oil in Italy but we also have several other solutions for more special or bigger winches which are mostly build in The Netherlands.
