Using both electric and internal combustion (IC) trucks have different disadvantages and advantages.
Electric engines need less maintenance, and thus they cost less to maintain during their lifetime. The battery should last five years minimum if the manufacturer's guidelines for charging and maintenance are followed. Overnight charging costs are usually low. Electric trucks tend to be highly maneuverable and compact units, specially the kinds with three wheels. 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 easier on the natural environment and are not noisy.
Not suitable to be utilized in wet conditions are electric trucks. Because of the need for battery recharging, they cannot be continuously used. 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 need for battery charging, the forklift can be utilized throughout the evening and overnight. Supply and transport of fuel needs to be factored into costs. Initial costs 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 can be utilized in some indoor applications. IC Engine diesel/LPG makes more noise and higher emissions than electric. LPG has lower emissions compared to diesel.
