There are some advantages and disadvantages to utilizing both internal combustion (IC) and electric trucks.
Electric engines cost less to maintain during their lifetime as they need less maintenance. The battery must last at least five years if the guidelines of the manufacturer for maintenance and charging are followed. Overnight charging costs are usually low. Electric trucks tend to be compact units and highly maneuverable, specially the three-wheel models. Drive, lift, tilt, auxiliary and acceleration speeds are adaptable and can be changed depending on the driver's preferences and the application. Electric trucks are easier on the environment and are quiet.
Electric trucks are not best to use in 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.
Best to be continuously utilized outdoors and on surfaces which are not even is the advantage of an IC engine diesel/LPG. With no requirement for battery charging, the forklift can be used throughout the evening and overnight. Supply and transport of fuel must be factored into costs. Initial costs are less than for an electric truck, but long term expenses connected to maintenance and fuel are higher. IC engines have larger capacities than electric, but less adaptability. LPG could be used in some indoor applications. IC Engine diesel/LPG produces more noise and higher emissions than electric. LPG has lower emissions than diesel.
