There are disadvantages and advantages to both internal combustion (IC) and electric trucks.
Electric engines cost less to maintain during their life span because they require much less maintenance. The battery must last five years minimum if the manufacturer's guidelines for maintenance and charging are followed. Expenses for overnight charging are normally low. Electric trucks tend to be compact units and highly maneuverable, especially the three-wheel models. Drive, lift, tilt, acceleration and auxiliary speeds are adjustable and can be changed depending on the preferences of the driver and the use. Electric trucks are easier on the natural environment and are quiet.
Electric trucks are not suitable for use in wet conditions. Due to the need for battery recharging, they cannot be used continuously. They are not suited to rough terrain. The energy consumption is high on continuous high lifts and ramp work.
Best to be continuously used outdoors and on surfaces that are not even is the advantage of an IC engine diesel/LPG. With no requirement for battery charging, the forklift could be used during the evening and overnight. Supply and transport of fuel needs to be factored into expenses. Initial expenses are less than for an electric truck, but long term costs related to maintenance and fuel are higher. IC engines have larger capacities than electric, but less adaptability. LPG could be used in some indoor applications. IC Engine diesel/LPG makes more noise and higher emissions compared to electric. LPG has lower emissions than diesel.
