Werkstattzug: Work Shop Train

Werkstattzug Machine Shop Truck

The German workshop train is reported to consist of eight vehicles, among which are (1) the spare parts truck which has a stake body and canvas top and carries various types of spare parts for automotive equipment stowed in cabinet bins; (2) the machine shop truck which has a van-type body and is equipped with electrically driven lathe, drill press, bench grinder, and valve grinding-machine, together with various tools used for automotive repair; (3) the electrical repair truck which has a van-type body and is equipped with armature grinder, battery chargers, soldering irons, spark plug tester, etc. The electrical repair truck is used in conjunction with automotive repair work as it is also equipped with wheel aligner and diesel injector testing machine.

The electrical motor-driven units of the two van-type trucks require an external source of current, believed to be either 220 volts or 380 volts inasmuch as the trucks have no generating equipment except for the starter and light circuits. By means of an electrical control panel, switches, and circuit breakers the correct voltage for use by the electric motors is selected from the external current, believed to emanate from a truck-drawn trailer fitted with generating equipment.

All three vehicles have the Bussing Nag 4½-ton truck chassis, Model 4500A four wheel drive.

The personnel of the entire train, including the foreman, drivers, electricians, tinsmiths, blacksmith, saddlemaker, painter, carpenter, and mechanics, numbers about thirty.

Portable Gantry Crane

Portable Gantry Crane

The portable Gantry Crane was manufactured in 1942 by J.S. Fries & Son, Frankfurt, Germany. It has a capacity of 33,000 pounds, and is used by field tank maintenance units in removing turrets and engines from heavy German tanks.

With a crew of eight men, the crane can be erected from traveling position to the operating position in an estimated time of twenty minutes. When the crane is in the operating position, it can be moved on its bogies on hard surface ground, or it can be run on rails that engage the flanges on the inside of the bogie wheels.

The equipment has a tendency to be top heavy in the traveling position. It is easily erected to the operating position because of its jack-knife tubular legs which are equipped with wire cable tackle blocks and manual winch.

The bridge is fabricated from welded “I” beams and angle iron shapes. The hoisting winch and motor assembly are permanently mounted at one end of the bridge. The motor, a ten-horsepower, three-phase, fifty-cycle 220/380-volt squirrel cage induction type, is equipped with magnetic friction brake and a two-station start-and-stop starter.

The hoisting block, a twin sheave type using a six-37-strand three-quarter-inch galvanized cable, can be raised or lowered manually when power is off.

The trolley is supported by four ball bearing flanged wheels and has ball bearing equipped sheaves. The trolley is traversed manually by a chain.
