There are some advantages and disadvantages to using both internal combustion (IC) and electric trucks.
Electric engines cost less to maintain over their lifetime as they need a lot less maintenance. The battery should last at least five years if the manufacturer's charging and maintenance guidelines are followed. Overnight charging expenses are usually low. Electric trucks tend to be very maneuverable and compact units, especially the kinds with three wheels. Drive, lift, tilt, auxiliary and acceleration speeds are adaptable and can be changed depending on the application and the driver's preferences. Electric trucks are easier on the environment and are quiet.
Electric trucks are not suitable for use during wet conditions. Because of the need for battery recharging, they cannot be continuously used. They are not suitable on rough terrain. The energy consumption is high on continuous high lifts and ramp work.
IC engine diesel/LPG has the advantage of being suitable for continuous outdoor application and uneven surfaces. With no need for battery charging, the forklift could be used 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 related to fuel and maintenance are higher. IC engines have larger capacities than electric, but less adaptability. LPG could be used in some indoor applications. IC Engine diesel/LPG produces more noise and higher emissions than electric. LPG has lower emissions than diesel.
