There are disadvantages and advantages to both internal combustion (IC) and electric trucks.
Electric engines cost less to maintain over their lifetime as they require a lot less maintenance. The battery must last five years minimum if the manufacturer's guidelines for maintenance and charging are followed. Costs for overnight charging are usually low. Electric trucks tend to be compact units and very maneuverable, particularly the models with three wheels. Drive, lift, tilt, acceleration and auxiliary speeds are adaptable and could be changed depending on the application and the preferences of the driver. Electric trucks are not noisy, and are easier on the 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 suited to rough terrain. The energy consumption is high on continuous high lifts and ramp work.
IC engine diesel/LPG has the advantage of being best for continuous outdoor use and uneven surfaces. With no requirement for battery charging, the forklift can be used during the evening and overnight. Supply and transport of fuel must be factored into expenses. Initial expenses are less than for an electric truck, but long term costs connected to fuel and maintenance are higher. IC engines have larger capacities than electric, but less adaptability. LPG could be utilized in some indoor applications. IC Engine diesel/LPG produces more noise and higher emissions compared to electric. LPG has lower emissions compared to diesel.
