Using both internal combustion (IC) and electric trucks have various disadvantages and advantages.
Electric engines need much less maintenance, and thus they cost less to maintain over their life span. The battery must last five years minimum if the manufacturer's maintenance and charging guidelines are followed. Costs for overnight charging are generally low. Electric trucks tend to be compact units and very maneuverable, particularly the types with three wheels. Drive, tilt, lift, auxiliary and acceleration speeds are adaptable and could be changed depending on the application and the driver's preferences. Electric trucks are easier on the natural environment and are quiet.
Electric trucks are not best to use in wet conditions. Due to 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 utilized outdoors and on surfaces which are uneven is the advantage of an IC engine diesel/LPG. With no need for battery charging, the forklift can be used throughout the evening and overnight. Supply and transport of fuel needs to be factored into expenses. Initial costs are less than for an electric truck, but long term expenses related to maintenance and fuel are higher. IC engines have larger capacities than electric, but less adaptability. LPG can be utilized in some indoor applications. IC Engine diesel/LPG produces more noise and higher emissions compared to electric. LPG has lower emissions compared to diesel.
