Analysis Series, Chapter 4: Trends in Materials Handling

HCO Innovations is publishing this eight-part series as an in-depth comparative analysis and discussion on Compressed Natural Gas (CNG) Internal Combustion (IC) motors and Alternating Current (AC) Eletric lift truck engines, Comparison Analysis of CNG (IC) vs. AC Electric Lift Trucks, by Will Van Ness, VP of Fleet Management at HCO Innovations. 

Comparison Analysis of CNG (IC) vs. AC Electric Lift Trucks (AC)

The materials handling industry continues to evolve at a rapid pace, particularly in the area of motive power propulsion. Tremendous technological advancements have been made over the past decade to directly address the rising cost of petrol (fossil fuels) along with stricter emission standards. Today’s MHE acquirers have more choices than ever when it comes to motive power propulsion and with the success seen amongst fleets utilizing alternative fuel sources such as lithium ion (LION) and Hydrogen Fuel Cell (HFC), the choices will most likely increase as time goes on. For the purpose of this discussion document, our focus will be on comparing AC Electric (AC) to Internal Combustion powered lift trucks (IC), specifically compressed natural gas (CNG).

Chapter 4: Trends in Materials Handling

A trend to increasingly narrower aisles in warehouses and distribution centers reflects the need to store more goods in the same amount of space than in the past (“cube utilization”). In addition to aisles shrinking, storage racks are being raised higher; meaning a lift truck working in these evolving environments must maneuver in smaller areas and lift loads higher.

Lift trucks also must be able to turn within tight spaces like the inside of half-full trailers where stacked goods reduce maneuvering space. In response, lift truck manufacturers are now making their products more compact. AC electric lift trucks designed specifically for narrow aisle applications are now serving areas where counterbalanced lift trucks cannot go. Electric lift trucks are most commonly used in indoor environments and regulated areas, such as refrigerators and freezers in grocery and food distribution centers. These are arenas where exhaust emissions in confined spaces would be a problem. Therefore, electric lift trucks excel in environments with medical and food products, which largely dominate the grocery industry, and in enclosed areas where toxic emissions like carbon monoxide would be a concern. Another strong niche for electric lift trucks is working around explosives and chemicals.

Evaluating only the market for 5,000-6,000 lb. capacity sit-down counterbalanced lift trucks, approximately 25 percent of the 80,000 of those lift trucks currently being used are electric. The remainder of the total are internal combustion lift truck models (LPG, diesel, gasoline, CNG, etc.), with LPG lift trucks owning the majority of that share.

Conclusions & Final Recap

We're Here To Help

Our customers are at the center of everything we do. HCO knows that many of you are navigating unprecedented challenges and we’re here to help.

The current economic environment has created stress on many of the core industries that this country relies on to thrive.
- Corporate liquidity is at a premium and the management of your balance sheet is critical.
- Bank and vendor leasing for equipment is tightening as corporate credit ratings are in flux and lenders are focused on securing their own capital.

HCO is leading through this disruption with customized forklift fleet programs that allow companies to 1) replace fleet assets and 2) service those assets without relying on banks or vendors for leasing. Our managed service programs allow companies to secure assets and service programs with no upfront capital, and no end of term lease obligations. We are reinventing the way companies access equipment and service. Please reach out to discuss whether this would be valuable to your company.

As we execute our business continuity plan, we will rely on the guidance from the Center for Disease Control, federal, state, and local governments to guide our decisions to keep our employees and our customers’ employees safe. We are committed to continuing to provide clients with our valuable services.
