There are some advantages and disadvantages to both internal combustion (IC) and electric trucks.
Electric engines cost less to maintain over their life span because they need less maintenance. The battery must last five years minimum if the manufacturer's charging and maintenance guidelines are followed. Costs for overnight charging are generally low. Electric trucks tend to be compact units and highly maneuverable, especially the kinds with three wheels. Drive, tilt, lift, auxiliary and acceleration speeds are adjustable and could be changed depending on the application and the preferences of the driver. Electric trucks are easier on the environment and are quiet.
Electric trucks are not suitable for use in wet conditions. Because of the need for battery recharging, they cannot be continuously utilized. They are not suited to rough terrain. The energy consumption is high on continuous high lifts and ramp work.
Best 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 could be utilized throughout the evening and overnight. Supply and transport of fuel should be factored into expenses. Initial costs are less than for an electric truck, but long term costs connected to maintenance and fuel are higher. IC engines have larger capacities than electric, but less adaptability. LPG can be used in some indoor applications. IC Engine diesel/LPG makes more noise and higher emissions than electric. LPG has lower emissions compared to diesel.
