There are disadvantages and advantages to utilizing both internal combustion (IC) and electric trucks.
Electric engines require less maintenance, and hence they cost less to maintain during their life span. The battery should last five years minimum if the guidelines of the manufacturer for maintenance and charging are followed. Overnight charging costs are usually low. Electric trucks tend to be highly maneuverable and compact units, especially the models with three wheels. Drive, lift, tilt, auxiliary and acceleration speeds are adjustable and can be changed depending on the preferences of the driver and the application. Electric trucks are quiet, and are easier on the natural environment.
Electric trucks are not best to 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 best for continuous outdoor application and uneven surfaces. With no need for battery charging, the forklift can be used throughout 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 expenses connected to maintenance and fuel are higher. IC engines have bigger capacities compared to electric, but less adaptability. LPG can be used in several indoor applications. IC Engine diesel/LPG makes more noise and higher emissions compared to electric. LPG has lower emissions than diesel.
