Utilizing both internal combustion (IC) and electric trucks have various advantages and disadvantages.
Electric engines cost less to maintain during their life span because they need a lot less maintenance. The battery should last five years minimum if the manufacturer's guidelines for charging and maintenance are followed. Costs for overnight charging are normally low. Electric trucks tend to be very maneuverable and compact units, specially the models with three wheels. Drive, lift, tilt, acceleration and auxiliary speeds are adjustable and could be changed depending on the preferences of the driver and the application. Electric trucks are not noisy, and are easier on the natural environment.
Electric trucks are not best to use in wet conditions. 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 ramp work and continuous high lifts.
Best to be continuously utilized outdoors and on surfaces which are not even is the advantage of an IC engine diesel/LPG. With no need for battery charging, the forklift can be utilized throughout the evening and overnight. Transport and supply of fuel needs to be factored into costs. Initial expenses are less than for an electric truck, but long term costs related to maintenance and fuel are higher. IC engines have bigger capacities than electric, but less adaptability. LPG could be used in some indoor applications. IC Engine diesel/LPG makes more noise and higher emissions than electric. LPG has lower emissions than diesel.
