In applications where the customer has a low level of load rotation and needs space optimisation, block stacking is the answer. Block stacking does not require any storage equipment, instead loaded pallets are placed directly on the floor and built up to a maximum stable height. Although it can optimize warehouse space up to 90%,
this type of storage is only applicable for loads with low handling frequency and/or a uniform load type. Lack of infrastructure also means that pallets needs to be placed precisely on top of each other for safety. This makes the manual operations tedious and time consuming.
