Using both internal combustion (IC) and electric trucks have different advantages and disadvantages.
Electric engines need less maintenance, and hence they cost less to maintain over their life span. The battery must last five years minimum if the guidelines of the manufacturer for maintenance and charging are followed. Costs for overnight charging are usually low. Electric trucks tend to be compact units and highly maneuverable, especially the types with three wheels. Drive, lift, tilt, auxiliary and acceleration speeds are adaptable and can be changed depending on the use and the preferences of the driver. Electric trucks are not noisy, 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 suitable on rough terrain. The energy consumption is high on ramp work and continuous high lifts.
Suitable to be continuously used outdoors and on surfaces that are uneven is the advantage of an IC engine diesel/LPG. With no requirement for battery charging, the forklift could be utilized during the evening and overnight. Transport and supply of fuel has to be factored into expenses. Initial costs 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 higher emissions and more noise than electric. LPG has lower emissions than diesel.
