There are some disadvantages and advantages to both internal combustion (IC) and electric trucks.
Electric engines need much less maintenance, and thus they cost less to maintain over their life span. The battery must last at least five years if the guidelines of the manufacturer for charging and maintenance are followed. Overnight charging expenses are normally low. Electric trucks tend to be compact units and highly maneuverable, specially the models with three wheels. Drive, lift, tilt, acceleration and auxiliary speeds are adjustable and could be changed depending on the use and the preferences of the driver. 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 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 during the evening and overnight. Supply and transport of fuel must be factored into costs. Initial expenses are less than for an electric truck, but long term expenses connected to fuel and maintenance are higher. IC engines have larger capacities compared to electric, but less adaptability. LPG can be utilized in some indoor applications. IC Engine diesel/LPG produces higher emissions and more noise compared to electric. LPG has lower emissions than diesel.
