Lift Trucks

Lithium batteries and high-efficiency chargers for lift trucks save time, money and the environment. When compared to traditional lead-acid technology, lithium batteries charge faster, last longer and deliver more usable energy with each discharge. With batteries charging faster and lasting longer, there’s less downtime. Li-ion batteries don’t need to be swapped, watered, or equalized, which streamlines operations and increases efficiency.

There are many different types of material handling lift trucks, from large sit down counter balance trucks to walkie pallet jacks. These industrial trucks are divided into classes, of which four are relevant to conversion to Li-ion based power systems:

  • Class I: Electric Motor Rider Forklifts
  • Class II: Electric Motor Narrow Aisle Forklifts (Reach Trucks, Order Pickers)
  • Class III: Electric Pallet Jacks, Stackers, and Tow Tractors
  • Class IV: Internal Combustion Cushion Tire Forklifts

CLASS I: ELECTRIC MOTOR RIDER FORKLIFTS

Class I Forklifts are electric motor riders. These electric-powered forklifts are ideal for loading and unloading tractor-trailers, handling pallets, and a number of other applications in industries ranging from cold food and beverage storage, retail, manufacturing and warehouses.

By definition, Class I forklifts are powered by a battery, which has historically been Flooded Lead Acid. As compared to Internal Combustion Engine (ICE) forklifts Class I forklifts are much quieter and create no emissions, making them a popular choice for indoor applications. Forklifts in this class, ranging in lift capacity from 3,000 to 40,000 pounds.

Electrical systems for Class I forklifts range between 24V and 80V, but they tend to require larger capacity and higher voltages than the other classes. Most will require a 48V or 80V Lithium SAFEFlex battery and a 30kW Lithium SAFEFlex charger to fast charge one or more forklifts simultaneously. Batteries on Class I forklifts also function as part of the counterweight to help maintain lifting capacity, so Green Cubes offers batteries with extra weight ballast in order to be a drop-in replacement for lead acid batteries.

CLASS II: ELECTRIC MOTOR NARROW AISLE

Class II lift trucks are electric, narrow aisle models. They are designed with maneuverability that allows them to operate in tight spaces and narrow aisles, picking and putting away inventory, and these trucks provide enterprises the ability to increase vertical racking space without expanding their current warehouse footprint. Some examples or Class II industrial trucks are reach trucks and order pickers.

Reach trucks and order pickers usually require Lithium SAFEFlex batteries in the middle sizes and voltages offered by Green Cubes. They range from 24V to 48V. Customers can choose a 15kW or 30kW Lithium SAFEFlex charger, depending on their requirements.

CLASS III: ELECTRIC PALLET JACKS / STACKERS / TOW TRACTORS

Class III equipment includes electric pallet jacks, stackers, and tow tractors, which come in both rider and walk behind (“walkie”) models. They are generally used for unloading deliveries and moving loads to a staging area where they can be handled by other types of forklifts.

Pallet jacks and stackers require smaller batteries than Class I and II equipment and usually operate at 24V. For these applications we recommend our 15kW charger, which can charge three pallet jacks at a time.

CLASS IV: INTERNAL COMBUSTION ENGINE CUSHION TIRE

Class IV Forklifts are ICE cushion tire trucks. This class of sit-down forklifts is designed for indoor use but run on diesel fuel, LP gas, gasoline, or compressed natural gas. Lithium SAFEFlex batteries are an appropriate replacement for ICE powered forklifts because they are emissions free and often provide an economic benefit over diesel or propane.

ABOUT LITHIUM SAFEFLEX BATTERIES:

Lithium SAFEFlex is the most advanced motive power lithium batteries for all electric material handling (MHE) classes 1-3, including small pallet jacks, end riders, center riders, narrow aisle forklifts, 3-4 wheel forklifts, large turret trucks and other material handling vehicles.

Lithium SAFEFlex is the integration of Lithium Iron Phosphate cells, electronics, packaging and a software platform that was designed specifically for the rugged requirements of material handling. The advanced mechanical packaging meets the impact forces of a large forklift and the rugged automotive-grade Battery Management System (BMS) makes Lithium SAFEFlex the most reliable lithium battery for the material handling industry.

Benefits of Lithium SAFEFlex batteries:

  • One battery per vehicle – Designed for opportunity charging and much higher cycle life means battery swapping is a thing of the past. Reclaim your battery room and free up floor space
  • Safety and reliability – Our motive power batteries are constructed from UL approved components. Voltage, current and temperature are continuously monitored while safety is controlled through contactors. Lithium Iron Phosphate chemistry is the saftest chemistry in the lithium-ion battery category
  • Flexible applications – Available for all electric material handling classes 1-3, small Pallet Jacks, End Riders, Center Riders, Narrow Aisle Forklifts, 3-4 Wheel Forklifts, large Turret Trucks. Lithium SAFEFlex batteries are ballasted for heavy counterbalance applications when necessary
  • Energy and cost savings – Recharge efficiency of 98%+ drives electrical savings and reduces damaging effects of heating batteries
  • Plug and play – Single point battery connection replicates today’s lead acid batteries without any special modifications. Drop-in replacement happens once and battery swaps are eliminated forever
  • Maintenance free – Weekly watering and equalization is not required. Lithium motive power batteries are sealed and do not require acid. The BMS automatically monitors and conditions the battery

Benefits of Lithium SAFEFlex Chargers

  • CAN communication and voltage detection – enables charging multiple trucks simultaneously for lower utility cost
  • High efficiency – small and light for wall mount or ceiling placement and low footprint
  • Modular design allows for charging 1, 2 or 3 batteries from a single charger

Customer Ratings and Reviews

Green Cubes is a great company, great engineers, great product. That’s been kind of my number one go to [lithium] battery.

President, Industrial Power Company

The thing I like about Green Cubes is that they have other lines of business outside of material handling batteries, they have been in the lithium world for a long time. I can trust they will likely stay in business

VP, Industrial Battery Company

Green Cubes [differentiates] on its capability to custom design for things like the hardware, the firmware, and inverters. They also have economies of scale because they make battery systems for things like forklifts.

VP, Powered Cart OEM

I am doing some work with them right now. We’re learning their products, and looking at demos. They have good people. They seem like they know the technology well – they say they’re a technology company. I like that they’ve been in the lithium business a long time. I can trust they will likely stay in business.

Sales Manager, Industrial Battery Company

Green Cubes Technology would be my go-to for lithium applications.

Branch Manager, OEM

I’ve told my friends at Green Cubes, I don’t plan on going anywhere. I believe in loyalty.
