The distance between two casters should ideally not exceed 48″ and should be greater than 24″.

For larger carts more than 48″ long, add two wheels to the center of the cart. Otherwise, the pipes could bend under weight.

For a fully efficient cart, swivel and fix casters position is very important.

For carts longer than 72″, swivel casters are at both ends of the cart and the fixed casters are at the center.

For carts shorter than 72″, the two rows of swivel casters are in the middle and at the end of the cart – where the handles are. The fix ones are at the opposite end.

It’s preferable to use 6″ casters or more in diameter when carts goes outside, uses ramps or are used on damaged floors.

We use rod wheels on narrow carts that does small trips, weight less than 400 pounds and that are unfrequently used.

We use plate-mounted wheels for larger carts that does longer trips at high frequency uses with heavy loads.

It’s advisable not to exceed 60″ in height in order to ensure that the driver has sufficient visibility for a safer work floor.

The height of the handles may vary.

For a horizontal handle, the heights range is from 36″ to 44″. For the best grip, the handle must be at least 20″ long.

Vertical handles are generally positioned between 36″ and 51″ in height.

To avoid excessive loads on the shoulders, the distance between the handles should not exceed 18″.
