Ruhrwerke Zugmaschine – traction engines of 15, 30 and 50 hp, two- to four-cylinder engines, weights of around 1,800 to 6,000 kg, 600 to 800 rpm
The Ruhrwerke traction engines are recorded in the register in three power steps whose type designations directly name the engine power in hp: 15 hp, 30 hp and 50 hp. Cylinder count rises with the power step, from two on the smallest to four on the largest version, a principle common on traction engines of this type, raising output through displacement rather than a higher engine speed.

The register lists here 3 versions with 15 to 50 hp from two- to four-cylinder engines, weights from around 1,800 kg on the 15-hp version to around 6,000 kg on the 50-hp version, and a rated speed of 600 to 800 rpm.
With a rated speed of only 600 to 800 rpm, these traction engines rank among the slow-running, robustly built engines typical of continuous pulling and drive duty in agriculture and industry in the first half of the 20th century; the weight, rising sharply with power, points to a correspondingly massive design built for durability.
On a used example of these traction engines, the condition of the crankshaft and bearings of the slow-running engine, the tightness of the cylinders and cooling system, rust on the frame and sheet-metal parts, and the condition of the drive belt or clutch all count; given the high age and limited spread of these machines, spare parts can usually only be sourced through specialist collectors or by remanufacture.
