There are quite a few reach trucks manufactured today that lift to 12M that require a stacking aisle greater than 3M. Many of these are being replaced with articulated man down machines that lift to 12M and that operate in aisles of approx 2.1M. These are working with better performance results than reach trucks because of their reduced aisle size, greater lifting capacity, high performance lift and lower speeds and the ability to work indoors and out.
