There are some disadvantages and advantages to using both electric and internal combustion (IC) trucks.
Electric engines cost less to maintain over their lifetime because they require much less maintenance. The battery must last five years minimum if the manufacturer's guidelines for charging and maintenance are followed. Expenses for overnight charging are usually low. Electric trucks tend to be very maneuverable and compact units, especially the three-wheel models. Drive, tilt, lift, auxiliary and acceleration speeds are adaptable and could be changed depending on the driver's preferences and the use. Electric trucks are easier on the natural environment and are not noisy.
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 suitable on rough terrain. The energy consumption is high on continuous high lifts and ramp work.
Best to be continuously utilized outdoors and on surfaces which are uneven is the advantage of an IC engine diesel/LPG. With no requirement for battery charging, the forklift can be used throughout the evening and overnight. Supply and transport of fuel must be factored into costs. Initial costs are less than for an electric truck, but long term expenses connected to maintenance and fuel are higher. IC engines have larger capacities than electric, but less adaptability. LPG could be used in several indoor applications. IC Engine diesel/LPG produces more noise and higher emissions compared to electric. LPG has lower emissions compared to diesel.
