Propane forklifts are perfect for multiple shift operations. A propane fuel cylinder packs enough fuel for up to two shifts under heavy operation. And cylinders can be changed out in less than five minutes.
Electric-powered models use batteries, which must be changed out, cooled, and then recharged for up to eight hours. Warehouses with more than one shift must invest in extra batteries and a battery hoist, because electric forklift batteries weigh 2,400-3,500 lbs.
