There are some disadvantages and advantages to utilizing both internal combustion (IC) and electric trucks.
Electric engines require less maintenance, and thus they cost less to maintain over their life span. The battery should last five years minimum if the guidelines of the manufacturer for charging and maintenance are followed. Costs for overnight charging are normally low. Electric trucks tend to be very maneuverable and compact units, especially the models with three wheels. Drive, tilt, lift, auxiliary and acceleration speeds are adjustable and can be changed depending on the driver's preferences and the use. Electric trucks are quiet, and are easier on the natural environment.
Electric trucks are not best to use during 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 ramp work and continuous high lifts.
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 could be used throughout the evening and overnight. Transport and supply of fuel should be factored into expenses. Initial expenses are less than for an electric truck, but long term expenses connected to fuel and maintenance are higher. IC engines have larger capacities than electric, but less adaptability. LPG can be used in some indoor applications. IC Engine diesel/LPG makes more noise and higher emissions than electric. LPG has lower emissions than diesel.
