There are disadvantages and advantages to both electric and internal combustion (IC) trucks.
Electric engines require much less maintenance, and therefore they cost less to maintain over their lifetime. The battery should last at least five years if the manufacturer's maintenance and charging guidelines are followed. Overnight charging costs are generally low. Electric trucks tend to be very maneuverable and compact units, especially the types with three wheels. Drive, tilt, lift, acceleration and auxiliary speeds are adjustable and can be changed depending on the use and the driver's preferences. Electric trucks are easier on the environment and are not noisy.
Electric trucks are not suitable for use in wet conditions. Due to the need for battery recharging, they cannot be continuously utilized. 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 application and uneven surfaces. With no requirement for battery charging, the forklift can be utilized throughout the evening and overnight. Supply and transport of fuel must be factored into costs. Initial expenses are less than for an electric truck, but long term expenses related to fuel and maintenance are higher. IC engines have bigger capacities than electric, but less adaptability. LPG could be utilized in some indoor applications. IC Engine diesel/LPG makes more noise and higher emissions than electric. LPG has lower emissions than diesel.
