Actually this is such a big cost that about two weeks ago the shop held a training course for "Lulls" ( A brand name for all terrain telescoping forklifts).
In MA a hydraulic operators license is needed to operate these machines, but the up side is you can pick up a pallet deep in a trailer from the ground drive it across deep mud and stick it in a 5th floor window.
Fixtures, cable panels etc all get places on the their floors or the highest floor we can reach usually 3rd to 5th depending on pallet weight and access to the building.
