Completion of data :
The working equipment of the machine is mounted on a two-axle wheeled chassis. The machine chassis is two-piece. Its rear part is composed of a frame and a rear axle. The front part consists of a cab and a front axle. The two parts are connected by a joint. This allows it to turn easily and to be used as a loader. On the rear part there is an engine with generator and pump drive, on the front part there are working aggregates : loader, winch and cab.
The cab is equipped with a filter-ventilation device and is heated. In the cab there are two seats for the driver and the helper. There is a warning beacon on the roof of the cab.
The Electric traction allows smooth forward and reverse travel in two driving modes, does not require mechanical gears and automatically adapts the tractive force to the driving resistance.

The change of travel is achieved by rotating the front relative to the rear around a vertical pivot of the linkage. The axles are not sprung.
The wheel dozer has universal use. It can work in rocks of class 1 to 3 and partly in class 4. The shovel can be used to excavate the soil with the scarifying blades, it can be raked like a bulldozer, and soil and other loose material can be scooped up like a double-faced dredge and loaded with the shovel. The soil can be moved short distances in the shovel.

The DOC provides the following engineering work:
- digging of trenches, construction pits, shelters for live force and equipment,
- road modification and construction, levelling uneven ground, covering craters, pits, slope improvement, vegetation clearance, and more,
- removing cave-ins, debris from roads, clearing equipment on forest roads,
- bank treatment on watercourses to ensure water entrances, bottom treatment of water obstacles for wading up to 1.25 m high,
- freeing equipment using winch, towing trailers,
- moving large diameter logs clamped between the jaws of a shovel,
- electric arc metal cutting or welding,
- lifting loads by the teeth of the shovel up to 3000 kg.

Engine : T 930-42 - 12-cylinder, four-stroke, fork-ignition, direct fuel injection diesel engine, turbocharged by two turbochargers.
Cylinder capacity :17628 cm3
[Generator :TD-830 A - DC derivative,
Power : 160 kW
Fuel and oil fillings : fuel tank 480 l - engine oil tank 40 l - hydraulic fluid tank 500 l.

Attachments : snow extender for snow removal. Mounted on the shovel. It consists of an arrow plough, a skid steer, 2 fixing tugs and 2 tug holders.

On the basis of the format requirements WELL-Management Ženijného troops to the executive, viacúčelový machine pre ground work sa started in half to 60.years 20. day in cooperation VVTÚ and Stavostroj n. c. Nové Město nad Metují the development of a new ženijného engine, and the pre needs ČSĽA. Výsledkom vývoja bol chain-link harrow ženijný machine, called aj ako "UŽAS" (chain-link harrow ženijný armádny machine). Machine bol under the designation Dozer rotary paddle (DOC ) established in the arsenal of the ČSĽA in 1967.

Upgraded verzia is referred to as a dozer paddle DOCK-M. Since 1978 it gradually vo vojskách nahradzoval more modern, but change powerful wheeled loader CN-251.
