Utilizing both internal combustion (IC) and electric trucks have different disadvantages and advantages.
Electric engines cost less to maintain during their life span because they need less maintenance. The battery must last at least five years if the manufacturer's maintenance and charging guidelines are followed. Costs for overnight charging are normally low. Electric trucks tend to be very maneuverable and compact units, specially the three-wheel models. Drive, lift, tilt, auxiliary and acceleration speeds are adjustable and could be changed depending on the preferences of the driver and the use. Electric trucks are easier on the natural environment and are quiet.
Electric trucks are not suitable for use in wet conditions. Because of the need for battery recharging, they cannot be constantly used. They are not suitable on rough terrain. The energy consumption is high on ramp work and continuous high lifts.
Best to be continuously used outdoors and on surfaces which are not even is the advantage of an IC engine diesel/LPG. With no need for battery charging, the forklift could be utilized throughout the evening and overnight. Supply and transport of fuel should be factored into costs. Initial costs are less than for an electric truck, but long term expenses related to fuel and maintenance are higher. IC engines have bigger capacities compared to electric, but less adaptability. LPG can be used in some indoor applications. IC Engine diesel/LPG makes more noise and higher emissions than electric. LPG has lower emissions than diesel.
