There are some advantages and disadvantages to both internal combustion (IC) and electric trucks.
Electric engines need less maintenance, and therefore they cost less to maintain over their life span. The battery should last at least five years if the manufacturer's guidelines for maintenance and charging are followed. Expenses for overnight charging are usually low. Electric trucks tend to be very maneuverable and compact units, specially the three-wheel models. Drive, tilt, lift, acceleration and auxiliary speeds are adjustable and can be changed depending on the application and the driver's preferences. Electric trucks are quiet, and are easier on the natural environment.
Electric trucks are not suitable for use during wet conditions. Because of the need for battery recharging, they cannot be continuously used. They are not suitable on rough terrain. The energy consumption is high on continuous high lifts and ramp work.
Suitable to be continuously used outdoors and on surfaces that are uneven is the advantage of an IC engine diesel/LPG. With no requirement for battery charging, the forklift can be utilized 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 than electric, but less adaptability. LPG could be used in several indoor applications. IC Engine diesel/LPG produces more noise and higher emissions compared to electric. LPG has lower emissions than diesel.
