Utilizing both internal combustion (IC) and electric trucks have various disadvantages and advantages.
Electric engines cost less to maintain during their lifetime because they require less maintenance. The battery must last at least five years if the manufacturer's maintenance and charging guidelines are followed. Overnight charging costs are normally low. Electric trucks tend to be compact units and highly maneuverable, particularly the models with three wheels. Drive, tilt, lift, acceleration and auxiliary speeds are adjustable and could be changed depending on the application and the preferences of the driver. Electric trucks are easier on the environment and are quiet.
Electric trucks are not suitable for use in wet conditions. Because of the need for battery recharging, they cannot be continuously utilized. They are not suitable on rough terrain. The energy consumption is high on ramp work and continuous high lifts.
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 during the evening and overnight. Transport and supply of fuel should be factored into costs. 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 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 than diesel.
