Proven and Innovative Energy Systems from Linde

Energy Systems for Every Occasion

The choice of energy system has become an increasingly important factor in intralogistics, with particular attention being paid to Total Cost of Ownership, or TCO for short. With this in mind, it is not just the purchase price that plays an important role when buying a forklift truck but also the operating costs and therefore the energy costs. Each application has its own requirements. These include aspects such as space requirement for refueling or charging, energy costs, and environmental sustainability.

This is why, alongside combustion engines and lead-acid batteries, lithium-ion batteries and fuel cells are increasingly being mentioned among the preferred solutions. Linde Material Handling offers the latest technology for every energy system, along with a wide range of models and comprehensive advice and services.

Combustion Engine

Strong Performance up to 18 Metric Tons

Combustion engines have proven themselves for use in intralogistics. For decades, Linde Material Handling has been setting the standards for productivity and cost-effectiveness in the development of internal combustion (IC) trucks. Users can choose between diesel engines or gas power with propellant or natural gas. In the case of diesel, IC trucks are used outside the covered business premises; propellant and natural gas trucks are also suitable for use for a variety of indoor applications.

Trucks with combustion engines offer a particular advantage over other systems: their large ground clearance means they can handle even the most uneven ground conditions. Above all, they also impress thanks to their powerful engine performance. They can handle load capacities up to 18 metric tons and are suitable for heavy-duty applications.

Linde forklift trucks have low-noise and economical engines and can be used for many operating hours without interruption. The service intervals are impressively long, and easy to access service modules ensure that maintenance processes are quickly dealt with.

A Sensitive Powerhouse

Linde was the first company to use a hydrostatic drive for IC trucks. This features a pump which is powered by the internal combustion engine. This pump transmits power in the form of oil pressure via a closed circuit linked to the two hydraulic engines in the drive axle. The driver controls the volume and direction of the oil flow—and therefore the speed and direction of the truck—using two pedals: the Linde dual pedal control.

The truck’s direction can be changed simply by switching pedals. When doing so, the closed oil circuit brakes the truck, meaning the braking system is just as superfluous as a clutch and transmission. This way, Linde’s hydrostatic drive is able to work continuously, entirely uniformly, and smoothly. This innovative form of transmission is what gives Linde’s internal combustion trucks their dexterity and efficiency.

Lead-acid Batteries

Ideal for light- to medium-duty applications

Electric forklift trucks and warehouse trucks with lead-acid batteries remain a good alternative for reduced utilization. This applies, for example, for retailers who only need the truck for loading and unloading for a few hours each day. Investment costs are similar for both IC trucks and electric forklift trucks with lead-acid batteries. Lead-acid trucks are generally somewhat more economical in terms of servicing and are also suitable for indoor use. This technology has proven itself over decades of use.

In order to ensure accurate operational planning, the remaining battery level display on Linde electric forklift trucks and warehouse handling equipment is accurate to the minute. In multi-shift operation, a battery change is generally required but, with a total of five options for Linde electric forklift trucks, this process is particularly flexible. There is also the option of ordering the truck with an integrated charger. Since the truck’s applications are extremely varied, Linde offers a variety of different battery capacities for the relevant intensity and duration of use.

Lithium-ion Batteries

Flexibility Is Key

One challenge in electromobility is ensuring that the trucks have the same availability as they do with combustion engines. This is where lithium-ion (Li-ION) technology comes into play, providing a whole range of advantages for electric forklift trucks and warehouse trucks alike compared to lead-acid batteries.

Costly and time-consuming battery changes are no longer required, as the battery can also be charged in the interim during short breaks. The combination of Li-ION battery and Linde charger increases the overall level of efficiency by up to 30 percent compared to lead-acid batteries. This leads to lower energy costs. A constant voltage means there is no performance loss even when the battery’s charge level is dropping. Also, since there are no longer any battery gases emitted, additional investment in battery charging areas and ventilation is no longer required.

The Linde Li-ION solution increases truck availability and makes operation more cost-effective, safer, and more sustainable. It is generally suitable for all applications. Its advantages really come into play for intensive applications, such as multi-shift operation, use in cold stores or in the beverage industry for example, but also for particularly sensitive working areas such as in the pharmaceutical and food industries. Different battery capacities are also available in combination with different charging capacities, ensuring a high level of flexibility.

For companies looking for an emissions-free alternative, forklift trucks and warehouse trucks with Lithium-ion batteries are a good option. Linde provides an advisory tool for calculating the Total Cost of Ownership (TCO) and which can be customized for different applications. Based on the individual customer application, the calculator shows which energy package is most suitable.

Fuel Cells

Lightning-Fast Refueling

In addition to the application requirements, aspects such as the space required for refueling or charging, energy costs, and environmental sustainability play an important role when searching for the right energy system. Fuel cells offer an interesting alternative here. In the fuel cell, hydrogen and oxygen react to produce electricity, heat and water.

Forklift trucks with fuel cells can be refueled with hydrogen in just one to three minutes. The high availability of the trucks is a major advantage in tough multi-shift operation. This makes the technology of interest for use in production environments as well as intensive logistics services. The infrastructure for hydrogen refueling can also be implemented in space-saving fashion.

As the costs for hydrogen have fallen significantly in the last few years this has also brought advantages in terms of operating costs. The fact that time-consuming battery changes are no longer required, coupled with the fast refueling times, has enabled an increase in productivity, safety, and hygiene.

Infrastructure Requirements

Depending on the operating requirements, fuel cell technology already represents the ideal energy system for some companies today. Linde can develop a suitable solution concept on an individual basis. In order to guarantee efficient usage, certain requirements, such as fleet size, hydrogen infrastructure, and conveyors must be taken into account.
