Using both internal combustion (IC) and electric trucks have different disadvantages and advantages.
Electric engines require much less maintenance, and therefore they cost less to maintain over their life span. The battery must last at least five years if the manufacturer's charging and maintenance guidelines are followed. Expenses for overnight charging are generally low. Electric trucks tend to be very maneuverable and compact units, especially the types with three wheels. Drive, lift, tilt, acceleration and auxiliary speeds are adjustable and can be changed depending on the application and the preferences of the driver. 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 constantly utilized. They are not suitable on rough terrain. The energy consumption is high on ramp work and continuous high lifts.
Suitable to be continuously utilized outdoors and on surfaces which are uneven is the advantage of an IC engine diesel/LPG. With no need for battery charging, the forklift could be utilized during the evening and overnight. Transport and supply of fuel needs to be factored into expenses. Initial costs are less than for an electric truck, but long term costs related to fuel and maintenance are higher. IC engines have larger capacities compared to electric, but less adaptability. LPG can be used in some indoor applications. IC Engine diesel/LPG produces higher emissions and more noise than electric. LPG has lower emissions than diesel.
