There are disadvantages and advantages to utilizing both internal combustion (IC) and electric trucks.
Electric engines need much less maintenance, and therefore they cost less to maintain during their lifetime. The battery must last five years minimum if the manufacturer's guidelines for charging and maintenance are followed. Overnight charging expenses are normally 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 adjustable and could be changed depending on the driver's preferences and the application. Electric trucks are easier on the natural environment and are not noisy.
Not best to be used in wet conditions are electric trucks. Because of the need for battery recharging, they cannot be continuously used. They are not suited to rough terrain. The energy consumption is high on ramp work and continuous high lifts.
Suitable to be continuously utilized outdoors and on surfaces which are not even is the advantage of an IC engine diesel/LPG. With no requirement for battery charging, the forklift could be utilized during the evening and overnight. Supply and transport of fuel has to 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 higher emissions and more noise than electric. LPG has lower emissions than diesel.
