PSC1794

Overview
PSC1794

The AxleTech International PSC1794 planetary steerable axle is engineered to meet the increasing powerful demands of heavy duty rough terrain cranes. With an axle capacity range up to 58,000 lb (26,300 kg), this axle has meets the requirements for larger RT cranes. 

The PSC1794 planetary steer axle series offers a wide selection of overall gear reduction options that can be tailored to your specific needs. Engineered for compatibility with demanding traction conditions, the PSC1794 meets the trend of increased driveline torque, tire sizes, and loading requirements that provide an extra ruggedness for prolonged life. DCDL (driver-controlled differential lock) and NoSPIN® differential options are also available for improved traction vocational requirements. 

The PSC1794 design helps reduce OEM/end-user maintenance costs. A standard input pinion unitized seal reduces the likelihood of oil leaks. Permanently lubricated steering axle shafts are standard; eliminating this maintenance requirement. Extra axle housing magnets are optional to help reduce any metallic contamination between scheduled lubricant change intervals. Wheel mounted dual hydraulic 4 piston caliper/wheel end dry disc brakes are standard. Carrier input pinion mounted spring applied / hydraulic release park brake option is also available.
