Notes
1Pallets must be handled by the open side, without the lower planks.
2Can be used in the flow rack system, adapting the entry and exit areas of the racking units using split rollers.
3These forklifts must be guided, either mechanically (rail located on the floor), or wire guided (wire buried in the ground).
4Pallets cannot be picked up directly from the ground. Another forklift or reach truck is required to place or remove the pallet at the aisle entrance, or a mechanical transfer and positioning system can be used (roller conveyor, drag chains, shuttles, etc.).
5Guided at the top and bottom. Some machines are guided only at the bottom.
6When the pallets are moved sideways or are wider than the distance between the front skids of the forklift, the movement must be with these on said skids, having to increase the clearance between the ground and the first load level to the height of the chassis plus 7.9 inches.
