Princeton PIGGY BACK®The advantages really add up with the PiggyBack PB55.3X.
The 5,500 lb. capacity PB55.3X is the first unit in the industry equipped with a standard “Double Reach” feature. This unique feature, which adds an extending scissors reach system to the standard moving mast, doubles the length of the reach of the PB55.3X+ across the bed. With the PB55.3X+, your driver now can unload an entire truck or trailer from one side, even from positions where tanks or tandems are located.
The new PB series machines have been redesigned with new features on the inside and out to increase performance, safety, options, and simplify maintenance. The advantages really add up with the PiggyBack PB55.3X.
