Track and Go Kit for 4×4 Trucks

A quick kit for converting road going 2 wheel drive trucks into tracked snow capable machines.

We've seen kits for 4x4 trucks, however, this one is the most convenient that I've seen. With a combination of skiis and tracks built into each wheel drive unit, the stock wheels can generate plenty of propulsion when paired with low ground pressure and high traction. I'm not sure if slippage of the tire on top of the track unit is a problem.

Each Track N Go kit comes with four track units and two loading ramps. To attach the tracks onto the vehicle, place the tracks in front of each wheel on the ground with the ramps leading up to them and simply drive forward onto the units and clamp them on. Rubber rollers integrated on the device ensures the tire stays aligned side-to-side for steering.

These look to be a bit less robust than other full track bolt-on kits; however, the convenience factor is high. I like that one could drive a truck to a location and then easily affix the tracks when the snow becomes deep enough to warrant it.

Golf Cart Frame Up and Running

We have found an old 3 wheeled golf cart and rebuilt all the required parts to make it a reliable machine for this year's Burningman event.

This platform has a good gas motor, large electric starter/generator, and solid variable speed transmission. Next year, we plan to remove the rear wheels, extend the back, and add tracks.

It's hard to look too serious while riding a 3 wheel golf cart with red fun fir seats . . .

Tank Tricycle

Given theĀ constraintsĀ of managing steering and traction, Dave and I have settled on a tracked tricycle design similar to that used in WW2.

Super High Rolling Efficiency Concept

This is Greg Montie's concept of a high rolling efficiency track.

The idea is to have a single V-belt for low weight, and a high efficiency linear (smooth) roll motion. A chain of aluminium cleats are riveted to the V-belt to complete the track. The cleats wings are curved to the diameter of the pulley wheel. This makes for a smooth rolling surface for the pulleys to travel on.

The cleats are made from 0.032" (or 1/32") aluminium. This aids in weight reduction and allows for each cleat's connector tabs to flex while following the V-belt around the pulley wheel. The cleat wings are not very strong as they are cantilevered on either side of the V-belt. However, the strength is improved by the general curved shape of the cleat. Furthermore, each cleat wing is protected during its most loaded duration - directly under the pulley wheel that carries the majority of the vehicle weight. This is accomplished by welding drums on either side of the pulley wheel, of equal diameter, that directly support the cleat wings under load.
