![]() ![]() They have more wheel travel and ground clearance than the camelback. Struts go from the bottom of the bogey pivot out and under the axle. ![]() The mRIDE tandem has tapered leaves that rock above the bogey pivot then go out and above 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. These have front mounted carriers and in tandems the two axle housings are different. Other powered axles are available from Dana-Spicer and Meritor. This lets the driveshafts be in line from the transmission to and between the axles at a higher level above the ground. Mack powered axles have the drive carrier on top of the housing instead of the front of it like other manufacturers. Wheelbases are from 173 to 246 inches (440 to 620 cm) and 250 inches (640 cm) with a drop frame.ĭana-Spicer and Meritor supply air brakes, steering systems, driveshafts, and other components.įront axles are rated at 20,000 pounds (9,100 kg). The LR has more frame options than other Mack trucks, with drop frames available. The base rear suspension is a Mack tandem but other axle/suspension types are available. Front axles are on semi-elliptical leaf springs. The RDS is a fully automatic planetary gear transmission with a lock-up torque converter.Ī ladder frame with beam axles is used. Transmission Īllison RDS 6-speed transmissions are used on all models. It develops 329 horsepower (245 kW) and 1,000 pound force-feet (1,400 N⋅m) of torque. The Cummins Westport L9N is a 543 cubic inches (8.9 L) turbocharged inline six-cylinder natural gas engine. It is a 659 cubic inches (10.8 L) overhead cam turbocharged inline six-cylinder diesel engine. The Mack MP7 is the base engine in the LR. In 2020 an all-electric models was available. The LR is available with a Mack MP7 diesel and a Cummins Westport natural gas engine. Most other vendor components are also available but engine choice is very limited. Mack builds their own major components (engines, axles, and suspensions) and promotes an integrated design but all LRs use a vendor transmission. There are locations for a joystick and other controls. This system can also shift the transmission into neutral when it is applied. The service brakes can be electrically applied, allowing the driver to exit leaving them on. Total loaded weight can be up to 72,000 pounds (33,000 kg).Īdvanced electronics are used for engine, chassis, and body controls, as well as maintenance. It has a stand-up right-side (curb) driving position. The cab is mounted very low and forward, allowing a step up from the ground to the cab floor of only 17 inches (43 cm). ![]() The LR is a forward control cab-over-engine type. All three models are mechanically and visually similar. The LR is a direct evolution of the 1994 model LE and the upgraded 2007 TerraPro LE. Introduced in 2015 it remains in production in 2020. It is used in refuse service with front, side, and rear-loading refuse compactor bodies. The cab is very low-profile and has dual driving controls with a stand-up driving position on the right side. They are a forward control cab-over-engine type, where the driver sits in front of the axle. The Mack LR (Low Ride) is a series of heavy-duty ( Class 8) trucks built by Mack Trucks. If you experience difficulties with separating standard parts we are more than happy to give you qualified assistance.We greatly appreciate you choosing our 3D models and hope they will be of use.We look forward to continuously dealing with you.38,000–52,000 lb (17,000–24,000 kg)(tandem) It’s created accurately, in real units of measurement, qualitatively and maximally close to the original.Model formats:- *.max (3ds Max 2008 scanline)- *.max (3ds Max 2008 vray)- *.fbx (Multi Format)- *.obj (Multi Format)- *.3ds (Multi Format)- *.mb (Maya 8.5)- *.lwo (Lightwave 6)- *.c4d (Cinema 4D 11)* tire’s texture is not included in the set.* renders Are made in 3ds Max 2008 using vray 1.5 (studio environment is not included in the set)If you need any other formats we are more than happy to make them for you.The model is provided combined, all main parts are presented as separate parts therefore materials of objects are easy to be modified or removed and standard parts are easy to be replaced. The 3D model was created on real car base. ![]()
