Load Restraint System

The Transking Tightwinder (Truck Winch / Loadbinder) is a carefully engineered piece of equipment designed to give years of service and reduce manual input effort from drivers and operators.

Reduce the risk – protect against the risk of injury, reduce OH&S claims, and no more of that ever annoying winch bar kick back.

Tightwinder’s  robust construction consists of a heavy-duty cast gearbox with machine finished surfaces and a heavy duty pressed body designed to eliminate twist and distortion in normal operating conditions.

The strap through shaft is machined to take 2 interference fitting pressed strap guide plates to ensure smooth, reliable operation. The heavy-duty, bevelled gears are machine finished to the through shaft, which eliminates gear run out and enables smooth gear mesh.

Transking Tightwinder installed under the goose neck and over the drive for easier and safer access.

The Transking Tightwinder was originally developed to access difficult to get to places.

After many years Transking have further developed the world’s first two to one reduction angle drive load binder for trucks and trailers, it fits into a standard slide track and has a rotating gear head if required.

It has been the load security system of choice of many transport operators. It is up to four tonne rated to Aus standards and will take 50 mm 75m and 100mm strap. It has very little kick back when releasing tension, further reducing the possibility of injury and insurance claims, Its 32mm (wheel nut socket) virtually eliminates the possibility of bar slippage its two to one reduction gear box makes it so easy to obtain strap tension safer.

Transking Tightwinder makes it easier, safer and faster to secure your load when your trailer is fitted with under-run protection.

Feedback from week 1 of Transking Tightwinder trial by Pickering Transport Group

You have made a great change to peoples lives already ~ Tony Ray

Just made the job so much easier, as stated over drive and tri axles particularly. Used to bring my electric drill with a socket on 150mm extension and wind up straps automatically. Tightwinder has made unstrapping safer and winding straps in better for my old arthritic hands, am very impressed and very happy ~ Steve Kallisch

Tightwinder is great, the load hadn’t moved… they’re excellent over the drive guards where you can struggle with a bar to get in the binder hole. 10 out of 10! ~ Pongo
