There are some disadvantages and advantages to using both internal combustion (IC) and electric trucks.
Electric engines need less maintenance, and therefore they cost less to maintain during their lifetime. The battery should 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 compact units and highly maneuverable, especially the kinds with three wheels. Drive, lift, tilt, acceleration and auxiliary speeds are adjustable and could be changed depending on the preferences of the driver and the application. Electric trucks are not noisy, and are easier on the environment.
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 continuous high lifts and ramp work.
IC engine diesel/LPG has the advantage of being best for continuous outdoor use and uneven surfaces. With no requirement for battery charging, the forklift can be utilized during 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 costs related to fuel and maintenance are higher. IC engines have larger capacities compared to electric, but less adaptability. LPG could be utilized in several indoor applications. IC Engine diesel/LPG produces more noise and higher emissions than electric. LPG has lower emissions than diesel.
