There are some advantages and disadvantages to both internal combustion (IC) and electric trucks.
Electric engines cost less to maintain during their lifetime as they require less maintenance. The battery should last five years minimum if the manufacturer's guidelines for charging and maintenance are followed. Overnight charging expenses are normally low. Electric trucks tend to be highly maneuverable and compact units, particularly the types with three wheels. Drive, tilt, lift, auxiliary and acceleration speeds are adaptable and can be changed depending on the driver's preferences and the application. Electric trucks are not noisy, and are easier on the natural environment.
Not suitable to be used in wet conditions are electric trucks. Because of the need for battery recharging, they cannot be utilized 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 use and uneven surfaces. With no requirement for battery charging, the forklift could be utilized during the evening and overnight. Supply and transport of fuel should be factored into expenses. Initial expenses are less than for an electric truck, but long term costs related to maintenance and fuel are higher. IC engines have bigger capacities than electric, but less adaptability. LPG could be used in some indoor applications. IC Engine diesel/LPG makes more noise and higher emissions compared to electric. LPG has lower emissions compared to diesel.
