Walking beams are very stable at low speeds and when stopped.įront loaders drive directly up to a container. They can have leaf springs or be solidly mounted. Walking beams have low bogie pivots with a balance beam going out and under the axles. The Camelback has multiple leaves that rock above the bogey pivot then curve down and under the axles. The Camelback tandem is the base rear suspension. Single rear axles rated at 18,500 pounds (8,400 kg) were used in small MC models, but most were 23,000 pounds (10,000 kg) and later MR models could be up to 30,000 pounds (14,000 kg). Steering could have up to a 45 cut, allowing very tight turning radius.

They direct full transmission output to either the drive-line or the pump, but not both at the same time.įront axles were rated at 10,500 or 12,000 pounds (4,800 or 5,400 kg) in light MC models but most models had between 12,000 to 20,000 pounds (5,400 to 9,100 kg). Transfer cases are used on concrete pumps.

Spicer 5-speed transmissions were available in 400 series trucks. They had 10 highway speeds and an optional low range. They are fully automatic planetary gear transmissions and later models have lock-up torque converters.įuller Roadranger transmissions are multi-range and suited for non-Maxidyne engines, which need more speeds.

Early models had 4 or 5 speeds and evolved with 5 or 6 speeds.

Other Mack manual transmissions have 5-10 speeds.Īllison automatic transmissions are widely used on refuse trucks. They originally had 5 speeds and developed into 8 speeds with low range gears. Mack Maxitorque transmissions are designed to work with Maxidyne engines and have fewer and wider-spaced gears than more conventional models. The lowest transmission gear can be either an on-road or very low off-road ratio. Each was suited for different applications.Īll manual transmission except the 6-speed had a 5-speed transmission, additional speeds were made with combinations of ranges. Mack, Allison, Fuller, and Spicer transmissions have been available, evolving over time. It developed 175 to 210 horsepower (130 to 157 kW) and 400 to 485 pound force-feet (542 to 658 N⋅m) of torque. The Caterpillar 3208 was a 636 cubic inches (10.4 L) V8 engine. The Mack E7 was a 728 cubic inches (11.9 L) turbocharged inline six-cylinder engine. it developed 200 to 350 horsepower (150 to 260 kW). The Mack E6 was a 672 cubic inches (11.0 L) turbocharged inline six-cylinder engine. This allows less shifting and smoother power "on the ground" when accelerating. Maxidyne high-torque engines have a wide power band and can develop maximum power below the governed speed they are rated at.

The MR was available with the E6 series and E7 series diesel engines. The MC was available with Mack E6 series and mid-range Caterpillar 3208 series diesel engines. The dashboard is lit from a single source through fibreoptics, this being a very early example of such an application. The cab tilts through a full 90 degrees, allowing for the radiator to be removed without first removing the cab. The engine intrudes considerably into the low cab. The low profile cab is of steel, while the doors are fibreglass. Export models are coded MCE and MRE respectively. The right-hand drive models also have the exhaust relocated to the left, while the turbocharger is mounted behind the engine so as to provide more space and less heat soak. This allowed Mack to market the truck in the United Kingdom without costly conversions, and also opened the trash truck market at home. The MC/MR was designed from the beginning to be available in right-hand drive as well as left-hand drive. The MR was widely used in refuse applications and continued in production until up-graded as the MRU TerraPro in 2007. The MC was used for custom-built fire equipment, when Mack exited the market in 1990 they discontinued the MC.

It is of a distinct "set back front axle" design (first seen on the Mack FM), with the driver compartment mounted ahead of the front axle and with a large, flat, divided windscreen covering almost half of the truck's frontal aspect. The Mack MC/MR series, also known as the "Cruise-Hauler", is a cabover truck first introduced in 1978.
