Using both electric and internal combustion (IC) trucks have various advantages and disadvantages.
Electric engines cost less to maintain during their life span because they require less maintenance. The battery should last five years minimum if the manufacturer's maintenance and charging guidelines are followed. Costs for overnight charging are generally low. Electric trucks tend to be very maneuverable and compact units, specially the three-wheel models. Drive, tilt, lift, acceleration and auxiliary speeds are adjustable and can be changed depending on the preferences of the driver and the application. Electric trucks are easier on the environment and are quiet.
Not suitable to be used during wet conditions are electric trucks. Due to the need for battery recharging, they cannot be utilized continuously. 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 best for continuous outdoor use and uneven surfaces. With no requirement for battery charging, the forklift could be used during the evening and overnight. Transport and supply of fuel needs to be factored into expenses. Initial expenses are less than for an electric truck, but long term costs 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 makes higher emissions and more noise than electric. LPG has lower emissions than diesel.
