Conestoga wagon toolbox painting, held at the National Gallery of Art. Note the heart motif at the toolbox's lid. Conestoga wagon production depended largely on the labors of blacksmiths and similar occupations since the colonial era of the United States, coinciding with increased land colonization and the rise of the American iron industry ...
An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
A round plate with a hole in its centre is located on the underside of the wagon. The plate on the wagon, in turn, sits on the plate on the axle between the wheels. This arrangement allows the axle and wheels to turn horizontally. The pin and hole arrangement could be reversed. The horse harness is attached to this assembly.
Therefore, the same wheel defect will register a much larger impact when a wagon is loaded, versus when it is empty. [4] A wheel condition monitoring detector monitors the condition of the wheel independent of sprung mass – independent of load. They do this by subtracting the wheel mass to get the normalized impact value.
Chuckwagon is a wagon working as a field kitchen. Conestoga wagon: A large, curved-bottom wagon for carrying commercial or government freight. See covered wagon. Float: A light, two-wheeled domestic delivery vehicle with the centre of its axle cranked downward to allow low loading and easy access to the goods. It was used particularly for milk ...
A trial in January 1952 saw a 52-wagon, 850 ton coal train run 127 miles (204 km) at an average of 38 miles per hour (61 km/h), compared to the usual maximum speed on the Midland main line of 25 miles per hour (40 km/h) for unfitted freight trains. [16] In 1952, 14% of open wagons, 55% of covered wagons and 80% of cattle trucks had vacuum brakes.
The Conestoga wagon was a heavy American wagon of English and German type from the late 18th century and into the 19th century. It was used for freight and drawn by teams of horses or oxen depending on load. The covered canvas top was supported on eight to twelve angled bows, rather than upright. Capacity was around 4 to 5 tons with no springs.
The axle box suspension usually consists of a spring between the bogie frame and axle bearings to permit up-and-down movement, and sliders to prevent lateral movement. A more modern design uses solid rubber springs. Brake equipment: Two main types are used: brake shoes that are pressed against the tread of the wheel, and disc brakes and pads.
