Utilizing both internal combustion (IC) and electric trucks have various disadvantages and advantages.
Electric engines require much less maintenance, and hence they cost less to maintain during their life span. The battery should last at least five years if the guidelines of the manufacturer for maintenance and charging are followed. Costs for overnight charging are generally low. Electric trucks tend to be compact units and very maneuverable, especially the three-wheel models. Drive, lift, tilt, auxiliary and acceleration speeds are adjustable and could be changed depending on the application and the driver's preferences. Electric trucks are quiet, and are easier on the environment.
Not best to be utilized in wet conditions are electric trucks. 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 suitable for continuous outdoor application and uneven surfaces. With no requirement for battery charging, the forklift could be utilized 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 expenses related to maintenance and fuel are higher. IC engines have larger capacities than electric, but less adaptability. LPG can be utilized in several indoor applications. IC Engine diesel/LPG makes more noise and higher emissions than electric. LPG has lower emissions compared to diesel.
