Using both internal combustion (IC) and electric trucks have various advantages and disadvantages.
Electric engines require much less maintenance, and thus they cost less to maintain over their lifetime. The battery should last five years minimum if the manufacturer's charging and maintenance guidelines are followed. Overnight charging expenses are generally low. Electric trucks tend to be compact units and highly maneuverable, especially the kinds with three wheels. Drive, lift, tilt, acceleration and auxiliary speeds are adjustable and could be changed depending on the driver's preferences and the application. Electric trucks are easier on the environment and are quiet.
Electric trucks are not suitable for use during wet conditions. Due to the need for battery recharging, they cannot be continuously used. They are not suited to rough terrain. The energy consumption is high on ramp work and continuous high lifts.
IC engine diesel/LPG has the advantage of being suitable for continuous outdoor use and uneven surfaces. With no need for battery charging, the forklift could be used during the evening and overnight. Transport and supply of fuel must be factored into costs. Initial costs are less than for an electric truck, but long term expenses connected to maintenance and fuel are higher. IC engines have bigger capacities than electric, but less adaptability. LPG can be used in some indoor applications. IC Engine diesel/LPG produces more noise and higher emissions compared to electric. LPG has lower emissions compared to diesel.
