Utilizing both internal combustion (IC) and electric trucks have various disadvantages and advantages.
Electric engines need less maintenance, and thus they cost less to maintain during their life span. The battery should last five years minimum if the manufacturer's maintenance and charging guidelines are followed. Overnight charging costs are usually low. Electric trucks tend to be highly maneuverable and compact units, especially the types with three wheels. Drive, lift, tilt, acceleration and auxiliary speeds are adaptable and can be changed depending on the application and the preferences of the driver. Electric trucks are quiet, and are easier on the environment.
Electric trucks are not suitable for use in wet conditions. Due to the need for battery recharging, they cannot be used continuously. 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 suitable for continuous outdoor use and uneven surfaces. With no requirement 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 expenses 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 several indoor applications. IC Engine diesel/LPG produces more noise and higher emissions compared to electric. LPG has lower emissions than diesel.
