Using both internal combustion (IC) and electric trucks have various 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 charging and maintenance guidelines are followed. Expenses for overnight charging are generally low. Electric trucks tend to be very maneuverable and compact units, especially the three-wheel models. Drive, lift, tilt, auxiliary and acceleration speeds are adaptable and could be changed depending on the driver's preferences and the use. Electric trucks are quiet, and are easier on the environment.
Electric trucks are not suitable for use in wet conditions. Due to 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 used during the evening and overnight. Transport and supply of fuel must be factored into costs. Initial expenses are less than for an electric truck, but long term expenses related to maintenance and fuel are higher. IC engines have bigger capacities compared to electric, but less adaptability. LPG can be utilized in several indoor applications. IC Engine diesel/LPG makes higher emissions and more noise compared to electric. LPG has lower emissions than diesel.
