Using both internal combustion (IC) and electric trucks have various advantages and disadvantages.
Electric engines require a lot less maintenance, and therefore they cost less to maintain during their lifetime. The battery should last five years minimum if the manufacturer's charging and maintenance guidelines are followed. Overnight charging expenses are generally low. Electric trucks tend to be compact units and highly maneuverable, specially the three-wheel models. Drive, tilt, lift, auxiliary and acceleration speeds are adaptable and could be changed depending on the driver's preferences and the application. Electric trucks are not noisy, and are easier on the natural environment.
Electric trucks are not best to use in wet conditions. Due to the need for battery recharging, they cannot be used continuously. They are not suited to rough terrain. The energy consumption is high on continuous high lifts and ramp work.
Best to be continuously utilized outdoors and on surfaces which are uneven is the advantage of an IC engine diesel/LPG. With no need for battery charging, the forklift could be utilized throughout the evening and overnight. Transport and supply of fuel needs 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 produces higher emissions and more noise compared to electric. LPG has lower emissions than diesel.
