Several factors should be considered, including: A special deep reach truck is required for double deep rack applications Widening the rack bay – The outriggers of a deep reach truck must be able to straddle the floor level pallets in order for the reach truck to reach the rear position.  As a result, the bay width needs to be slightly wider to allow room for the pallets and outriggers.  This option will slightly reduce the warehouse density. Adding a beam level at the floor – An alternative solution to making the bays wider would be to add a beam level at the floor, getting the bottom level pallets off the floor so that the outriggers can go under the pallets instead of around them.
