There are some advantages and disadvantages to utilizing both internal combustion (IC) and electric trucks.
Electric engines require less maintenance, and therefore they cost less to maintain during their lifetime. The battery should last five years minimum if the manufacturer's guidelines for charging and maintenance are followed. Costs for overnight charging are generally low. Electric trucks tend to be highly maneuverable and compact units, especially the kinds with three wheels. Drive, lift, tilt, acceleration and auxiliary speeds are adjustable and can be changed depending on the driver's preferences and the use. Electric trucks are quiet, and are easier on the natural environment.
Electric trucks are not suitable for use in wet conditions. Due to the need for battery recharging, they cannot be continuously used. 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 which are not even is the advantage of an IC engine diesel/LPG. With no need for battery charging, the forklift could be used during the evening and overnight. Transport and supply of fuel must be factored into costs. Initial expenses are less than for an electric truck, but long term costs connected 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 makes more noise and higher emissions than electric. LPG has lower emissions than diesel.
