A Schnabel car or Schnabel wagon is a specialized type of railroadfreight car. It is designed to carry heavy and oversized loads in such a way that the load makes up part of the car. The load is suspended between the two ends of the cars by lifting arms; the lifting arms are connected to an assembly of span bolsters that distribute the weight of the load and the lifting arm over many wheels.
When a Schnabel car is empty, the two lifting arms are connected to one another and the car can usually operate at normal freight train speeds. Some Schnabel cars include hydraulic equipment that will either lift or horizontally shift the load while in transit (at very low speeds) to clear obstructions along the car's route. As of 2012, there were 31 Schnabel cars operating in Europe, 30 in North America, 25 in Asia, and one in Australia.[1]
Types of wagons according the manner in which they are loaded A: Not self-supporting with low-loading bridge B: Self-supporting load C: Not self-supporting with through-loading bridge
The largest Schnabel car in public railroads operation, reporting number WECX 801, was completed in 2012 by Kasgro Railcar for Westinghouse Nuclear and is used in North America primarily to transport reactor containment vessels.[1] It has 36 axles (18 for each half). Each half contains nine trucks which are connected by a complex system of span bolsters. Its tare (unloaded) weight is 399.6 short tons (362.5 t; 356.8 long tons) and has a load limit of 1,017.9 short tons (923.4 t; 908.8 long tons) for a maximum gross weight of 1,417.5 short tons (1,285.9 t; 1,265.6 long tons). WECX 801 has the ability to shift its load 44 inches (112 cm) vertically and up to 40 inches (102 cm) laterally on either side of the car's center line.[2] When empty, this car measures 231 ft (70 m) long; for comparison, a conventional boxcar currently operating on North American railroads has a single two-axle truck at each end of the car, measures 50 to 89 feet (15.24 to 27.13 m) long and has a capacity of 70 to 105 short tons (64 to 95 t; 63 to 94 long tons). The train's speed is limited to 25 mph (40 km/h) when WECX 801 is empty, but only 15 mph (24 km/h) when loaded, and the system requires a crew of six operators in addition to the train's crew.[1]
The second largest Schnabel car in service, owned by ABB, bears the CEBX 800 registration, and is used in North America. Built by Krupp AG, it has 36 axles (18 for each half). Each half has 9 bogies linked together by a complex system of span bolsters. Its tare weight (empty mass) is 370 tonnes (360 long tons; 410 short tons). When empty, this wagon is 70.6 m (232 ft) long. It can carry a load of 34.5 m (113 ft) long and 852.3 tonnes (838.8 long tons; 939.5 short tons). By comparison, a classic boxcar has only one bogie with two axles at each end, is about 15 meters (49 ft) long and carries a load that does not exceed 80 tonnes (79 long tons; 88 short tons).[3]
Historyedit
A Karl-Gerät self-propelled siege mortar with its pair of Schnabel-cars on rails
The word Schnabel is from German Tragschnabelwagen, meaning "carrying-beak-wagon", because of the usually tapered shape of the lifting arms, resembling a bird's beak.
In World War II the German Wehrmacht used Schnabel cars for transporting the Karl-Gerät heavy-calibre (54 cm and 60 cm calibre) siege mortars. These were self-propelled with a continuous-track suspension chassis of substantial length to maneuver into a firing position over a short range, but depended on a pair of purpose-designed Schnabel cars for long-range transport by rail.[4] The same system was also used at the same time for the rail transport of the French FCM 2C super-heavy armoured fighting vehicle.
In the United States, the first Schnabel car, WECX 200, was built for Westinghouse Nuclear by manufacturer Greenville Steel Car in the 1960s.[1]
The Class Uaai low-loading wagon with special equipment is marketed Europe-wide exclusively by the heavy load department, Heavy Cargo + Service, of Nuclear Cargo + Service.[15][16]
