The good: Lift capacities up to 80,000 lbs. The operating costs can be lower than combustion engine forklifts. Electric forklifts charge at a station, so no need to store fuel on the premises. Cost for electricity can be a lot lower than fuel. Electric produces zero emissions. Noise reduction, and no propane tank at the rear of the forklift. The automatic braking reduces wear and reduces fatigue for the operator. Electric forklifts do not require engine oil or coolant. You can wait longer on your maintenance schedules.
The bad: You will need space to install a battery charging station. Voltage requirements could be an issue with older buildings. Most electric forklifts have a higher upfront cost to start with. Heavy batteries may require a special lift for changing them out.
