There are advantages and disadvantages to using both internal combustion (IC) and electric trucks.
Electric engines cost less to maintain over their lifetime as they require less maintenance. The battery should last at least five years if the manufacturer's maintenance and charging guidelines are followed. Costs for overnight charging are normally low. Electric trucks tend to be compact units and highly maneuverable, especially the models with three wheels. 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.
Not suitable to be utilized in wet conditions are electric trucks. 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 best for continuous outdoor use and uneven surfaces. With no requirement for battery charging, the forklift could be utilized during the evening and overnight. Transport and supply of fuel should be factored into costs. Initial costs 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 several indoor applications. IC Engine diesel/LPG produces higher emissions and more noise than electric. LPG has lower emissions than diesel.
