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. Costs for overnight charging are generally low. Electric trucks tend to be very maneuverable and compact units, specially the models with three wheels. Drive, tilt, lift, acceleration and auxiliary speeds are adjustable and could be changed depending on the driver's preferences and the application. Electric trucks are not noisy, and are easier on the environment.
Not suitable to be used in wet conditions are electric trucks. Due to the need for battery recharging, they cannot be used continuously. They are not suited to rough terrain. The energy consumption is high on continuous high lifts and ramp work.
Suitable to be continuously used outdoors and on surfaces which are uneven is the advantage of an IC engine diesel/LPG. With no requirement for battery charging, the forklift can be used throughout the evening and overnight. Supply and transport of fuel must be factored into expenses. Initial costs are less than for an electric truck, but long term expenses related to fuel and maintenance are higher. IC engines have bigger capacities compared to electric, but less adaptability. LPG can be utilized in several indoor applications. IC Engine diesel/LPG makes more noise and higher emissions than electric. LPG has lower emissions than diesel.
