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