There are some advantages and disadvantages to utilizing both internal combustion (IC) and electric trucks.
Electric engines cost less to maintain over their life span as they need much less maintenance. The battery must last five years minimum if the guidelines of the manufacturer for maintenance and charging are followed. Overnight charging expenses are usually low. Electric trucks tend to be compact units and highly maneuverable, specially the three-wheel models. Drive, tilt, lift, acceleration and auxiliary speeds are adaptable and could be changed depending on the preferences of the driver and the application. Electric trucks are quiet, and are easier on the natural environment.
Electric trucks are not best to use during wet conditions. Due to the need for battery recharging, they cannot be utilized continuously. They are not suited to 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 used during the evening and overnight. Supply and transport of fuel must be factored into costs. Initial costs are less than for an electric truck, but long term costs connected to maintenance and fuel are higher. IC engines have bigger capacities compared to electric, but less adaptability. LPG could be utilized in some indoor applications. IC Engine diesel/LPG makes more noise and higher emissions compared to electric. LPG has lower emissions compared to diesel.
