The Walkie Stacker is a battery-powered alternative to hand trucks and manual pallet jacks. These motorized hand trucks are found in virtually every manufacturing and distribution operation performing loading, unloading, order picking, stacking, staging, and internal transportation duties.

The motorized vehicles allow the operator to deliver or store the load much faster than using manual equipment. At the same time, operator fatigue is reduced and the possibility of injury associated with manually moving heavy materials is virtually eliminated.

On the down side, the vehicles typically have lower travel and lift speeds, which may limit their productivity in demanding operations or those covering greater distances. Capacity is limited to about 8000 lb (4000 lb for higher lifts); however, specially designed and constructed versions can go much higher. Gradeability is also a concern for some equipment.
