Princeton's new PB50.4+ Forklift adds 4-way functionality to our medium-duty machine and offers 5000 lbs of lifting capacity in a compact, yet powerful package. With the flip-of-a-switch the PB50.4+ converts into side-directional mode permitting the unit to be driven sideways to maneuver through restricted areas. Customers delivering lighter building materials, roofing, insulation, tile and agricultural products will find this new forklift to be everything they need and more. The PB50.4+ forklift has excellent stability. While weighing in at only about 5,000lbs, the machine feels sure footed and rugged. Engineers designed the machine to have excellent ground clearance AND a low center of gravity. Even more impressive, the machine was designed to have a shorter overall length. The PB50.4+ can be configured to a 56” overhang which allows for mounting to even 48 foot-long trailers.
