The M915A2 had a 775 cu in (12.7 L) Detroit Diesel Series 60 DDEC II developing 400 hp (300 kW) at 2100rpm and 1,400 lbf⋅ft (1,898 N⋅m) of torque at 1200rpm. Both are turbocharged inline 6 cylinder 4-stroke diesel engine, both engines are intercooled. The Cummins uses a water to air after-cooler while the Series 60 uses an air to air after ...
TTI HS-20 allowed shorter trucks to have higher weight limits than Formula B. For a 3-axle truck with an axle length of 14 feet (4.3 m), the weight limit increased from 46,500 pounds (21,100 kg) to 54,000 pounds (24,000 kg). [29] TTI HS-20 also failed to address the problem of multiple-span bridges. [28]
Flat wagons for carrying timber: the Class Snps 719 (front) and the Class Roos-t 642 (behind). Flat wagons (sometimes flat beds, flats or rail flats, US: flatcars), as classified by the International Union of Railways (UIC), are railway goods wagons that have a flat, usually full-length, deck (or 2 decks on car transporters) and little or no superstructure.
A flatcar (US) (also flat car, [1] or flatbed) is a piece of rolling stock that consists of an open, flat deck mounted on trucks (US) or bogies (UK) at each end. Occasionally, flat cars designed to carry extra heavy or extra large loads are mounted on a pair (or rarely, more) of bogies under each end.
A flatbed truck (or flatbed lorry in British English) is a type of truck the bodywork of which is just an entirely flat, level 'bed' with no sides or roof. This allows for quick and easy loading of goods, and consequently they are used to transport heavy loads that are not delicate or vulnerable to rain, and also for abnormal loads that require ...
A multi-axle bus is a bus or coach that has more than the conventional two axles (known as a twin-axle bus), usually three (known as a tri-axle bus), or more rarely, four (known as a quad-axle bus). Extra axles are usually added for legal axle load restriction reasons, or to accommodate different vehicle designs such as articulation, or rarely ...
The frame is usually fabricated steel. The primary flatbed surface can be constructed from wooden boards, plastic, steel or mesh. Flatbed casters can vary dramatically, made of solid rubber, air filled pneumatic or cast iron. The caster is generally the component on the flatbed trolley that limits the safe working capacity.
The axle load of a wheeled vehicle is the total weight bearing on the roadway for all wheels connected to a given axle.Axle load is an important design consideration in the engineering of roadways and railways, as both are designed to tolerate a maximum weight-per-axle (axle load); exceeding the maximum rated axle load will cause damage to the roadway or railway tracks.
