The aisle width (Ast) of a forklift is the minimum width of a straight aisle in which a truck carrying a given load can turn 90°.
The Ast is defined by:
Powered pallet trucks powered stackers, reach trucks and low-level order picking trucks:
Ast = Wa +√((l6 - x)² + (b12/2)²) + a
3-wheel counterbalanced trucks, 4-wheel counterbalanced trucks (when b12 is larger than two times the internal turning radius b13) and high-level order picking trucks:
Ast = Wa +√((l6 + x)² + (b12/2)²) + a
4-wheel counterbalanced trucks (when b12 is equal/smaller than two times the internal turning radius b13):
Ast = Wa + x + l6 + a
Very narrow aisle trucks are more complex to calculate. Your Toyota expert can support you.
You want to buy a new truck or rent an extra one for your operation? Some tips to make sure the truck is suitable for the space:
The aisle width and the choice of forklifts are highly dependent on each other. Generally, you could say that the larger the space, the higher the flexibility of using different types of material handling equipment. The tighter the space, the more specific the model needs to be.
Defining the forklift with the right measurements can have a positive impact on your storage capacity. When aisles are narrower, more racking can be placed which increases storage space.
The right forklift
Forklifts that are suitable when space is key and high lifting heights are required, are reach trucks, 3-wheel electric counterbalanced trucks or very narrow aisle trucks. But finding the right model is not all about space requirement, it needs to match your applications and driver needs.
