There are some disadvantages and advantages to using both electric and internal combustion (IC) trucks.
Electric engines cost less to maintain during their life span as they need much less maintenance. The battery must last at least five years if the guidelines of the manufacturer for charging and maintenance are followed. Overnight charging expenses are usually low. Electric trucks tend to be compact units and very maneuverable, especially the types with three wheels. Drive, lift, tilt, auxiliary and acceleration 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 environment.
Electric trucks are not best to use during wet conditions. Because of the need for battery recharging, they cannot be utilized continuously. 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 not even is the advantage of an IC engine diesel/LPG. With no need for battery charging, the forklift can be utilized during the evening and overnight. Transport and supply of fuel should be factored into expenses. Initial expenses are less than for an electric truck, but long term expenses related to maintenance and fuel are higher. IC engines have bigger capacities than electric, but less adaptability. LPG can be used in several indoor applications. IC Engine diesel/LPG makes higher emissions and more noise than electric. LPG has lower emissions compared to diesel.
