There are disadvantages and advantages to both internal combustion (IC) and electric trucks.
Electric engines require a lot less maintenance, and hence they cost less to maintain over their life span. The battery must last five years minimum if the guidelines of the manufacturer for maintenance and charging are followed. Costs for overnight charging are generally low. Electric trucks tend to be compact units and very maneuverable, particularly the three-wheel models. Drive, lift, tilt, acceleration and auxiliary speeds are adjustable and can be changed depending on the application and the preferences of the driver. Electric trucks are easier on the environment and are not noisy.
Electric trucks are not suitable for use in wet conditions. Because of 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 suitable for continuous outdoor application 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 expenses. Initial expenses are less than for an electric truck, but long term expenses related to maintenance and fuel are higher. IC engines have larger capacities compared to electric, but less adaptability. LPG can be utilized in several indoor applications. IC Engine diesel/LPG produces more noise and higher emissions compared to electric. LPG has lower emissions compared to diesel.
