There are advantages and disadvantages to using both internal combustion (IC) and electric trucks.
Electric engines cost less to maintain during their lifetime since they need a lot less maintenance. The battery should last at least five years if the guidelines of the manufacturer for maintenance and charging are followed. Overnight charging costs are generally low. Electric trucks tend to be compact units and highly maneuverable, especially the three-wheel models. Drive, tilt, lift, acceleration and auxiliary speeds are adaptable and can be changed depending on the preferences of the driver and the application. Electric trucks are quiet, and are easier on the natural environment.
Electric trucks are not suitable for use in wet conditions. Because of the need for battery recharging, they cannot be used continuously. They are not suitable on 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 use and uneven surfaces. With no requirement for battery charging, the forklift can be utilized during the evening and overnight. Supply and transport of fuel has 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 bigger capacities compared to electric, but less adaptability. LPG could be used in several indoor applications. IC Engine diesel/LPG produces higher emissions and more noise compared to electric. LPG has lower emissions compared to diesel.
