There are some disadvantages and advantages to both internal combustion (IC) and electric trucks.
Electric engines require less maintenance, and hence they cost less to maintain over their lifetime. The battery should last at least five years if the manufacturer's maintenance and charging guidelines are followed. Expenses for overnight charging are usually low. Electric trucks tend to be compact units and highly maneuverable, especially the types with three wheels. Drive, tilt, lift, acceleration and auxiliary speeds are adaptable and could be changed depending on the preferences of the driver and the application. Electric trucks are easier on the environment and are not noisy.
Not suitable to be used in wet conditions are electric trucks. Due to the need for battery recharging, they cannot be constantly utilized. They are not suitable on 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 application and uneven surfaces. With no requirement for battery charging, the forklift can be utilized throughout the evening and overnight. Supply and transport of fuel needs to be factored into expenses. Initial costs are less than for an electric truck, but long term costs related to fuel and maintenance are higher. IC engines have bigger capacities than electric, but less adaptability. LPG can be used in several indoor applications. IC Engine diesel/LPG produces higher emissions and more noise compared to electric. LPG has lower emissions than diesel.
