There are some disadvantages and advantages to both internal combustion (IC) and electric trucks.
Electric engines need a lot less maintenance, and hence they cost less to maintain during their lifetime. The battery must last at least five years if the manufacturer's charging and maintenance guidelines are followed. Costs for overnight charging are normally low. Electric trucks tend to be compact units and highly maneuverable, especially the three-wheel models. Drive, tilt, lift, auxiliary and acceleration speeds are adjustable and could be changed depending on the application and the driver's preferences. Electric trucks are not noisy, and are easier on the natural environment.
Electric trucks are not best to use in wet conditions. Due to the need for battery recharging, they cannot be continuously utilized. 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 best for continuous outdoor use and uneven surfaces. With no need for battery charging, the forklift could be used throughout the evening and overnight. Transport and supply of fuel must be factored into expenses. Initial costs are less than for an electric truck, but long term costs related to maintenance and fuel are higher. IC engines have bigger capacities compared to electric, but less adaptability. LPG could be used in several indoor applications. IC Engine diesel/LPG produces more noise and higher emissions than electric. LPG has lower emissions than diesel.
