PLANETARY RIGID AXLES
PRC1756 W3H SERIES
PRODUCT SUMMARY
The AxleTech International PRC1756 W3H series planetary rigid axle is engineered to meet the rugged demands placed on heavy-duty off-highway and specialty vehicles. Typical applications include heavy-duty lift trucks, dock spotters, loaders, mining and specialty vehicles. Axle capacities are vocation dependent and range from 37,500-110,000 lbs. (16,900-50,000 kg.) depending on vehicle vocation.
The PRC1756 W3H planetary rigid axle offers a wide selection of gear ratios, load capacities and track widths. The PRC1756 W3H is engineered for demanding traction conditions, and offers increased torque capacity versus previous models which increases life in rugged environments. A limited slip differential, as well as NoSPIN, DCDL and HDL, are available as options for improved traction. A right hand hypoid carrier option is also available for optimized driveline angles.
The PRC1756 W3H design helps reduce maintenance costs. Standard axle housing and wheel end magnets help reduce metallic contamination between scheduled lubrication intervals and eliminates initial drain requirement. A carrier input mounted caliper disc park brake option is available.
AxleTech International planetary rigid axles are tough, dependable, and thoroughly proven under the most severe conditions.
AxleTech International is the former ArvinMeritor Off-Highway and European Specialty Products Group.
