In the early 1930s Vickers Armstrong designed the Carden-Loyd carrier from the Carden-Loyd light tank.
It could carry a machine gun or tow a light gun.
In 1939 Captain Vivian Loyd developed a simple cross country vehicle primarily from existing parts from different manufacturers. The main components was a 4x2 Fordson truck that had tracks and suspension from a Vickers light tank added.
The Carriers were easy to drive as they had a steering wheel like a truck.
The suspension was a two-wheel Horstmann type. On each side was a large coiled spring with a single unit behind. The drive sprocket was located in the front while the idler was in the rear.
The Carden-Loyd Universal Carrier was driven by rear sprocket and had a 5.83:1 gear ratio.
The Carrier, Tracked, Loyd was driven by a front sprocket and had a 6.6:1 axle gear ratio.
The driver was on the right side with the machine gunner on the left. Four passengers could be carried in the rear area.
When the Carrier was towing a light gun the four man crew would be located in the Carrier.
The Carriers were powered by a Ford V-8 engine which was considered unreliable.
The Carrier, Tracked, Loyd had a British built Ford V-8 engine. This engine was mounted in the rear.
