Walkie stackers have several advantages over forklifts. Often more affordable and agile, walkie stackers give off no exhaust pollution and have fewer licensing requirements. They are ideal for indoor spaces, smaller capacities, and projects with shorter durations and lower budgets. In other circumstances, forklifts make a better option. Because of their size, walkie stackers are not suitable for heavy-duty loads. For projects with higher load capacities, larger transport distances, longer durations, and outdoor environments, you may be better off renting a forklift.
