Using both electric and internal combustion (IC) trucks have various disadvantages and advantages.
Electric engines need much less maintenance, and thus they cost less to maintain during their life span. The battery must last at least five years if the guidelines of the manufacturer for maintenance and charging are followed. Costs for overnight charging are usually low. Electric trucks tend to be compact units and highly maneuverable, specially the three-wheel models. Drive, tilt, lift, acceleration and auxiliary speeds are adaptable and can be changed depending on the driver's preferences and the application. Electric trucks are easier on the natural environment and are not noisy.
Electric trucks are not suitable for use during wet conditions. Because of the need for battery recharging, they cannot be used continuously. They are not suited to rough terrain. The energy consumption is high on ramp work and continuous high lifts.
Best to be continuously used outdoors and on surfaces which are uneven is the advantage of an IC engine diesel/LPG. With no need 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 expenses are less than for an electric truck, but long term expenses related to fuel and maintenance are higher. IC engines have larger capacities compared to electric, but less adaptability. LPG could be utilized in some indoor applications. IC Engine diesel/LPG produces higher emissions and more noise compared to electric. LPG has lower emissions compared to diesel.
