Energy systems for your intralogistics

Lead-acid battery, lithium-ion technology, fuel cell or the classic combustion engine? If you want to work economically and efficiently, you need to find the right energy system for your company. Every company has individual requirements for the energy supply of its industrial trucks. Not every technology is suitable for every company. The decision depends on various criteria and requires a high level of experience. As a genuine energy provider, GRUMA will help you find the perfect energy system for your intralogistics. We offer the latest technology, a wide range of models and comprehensive services for every energy system.

We will find the right energy system for you!

When selecting the right energy system, we examine the interaction of three main components: Vehicle, drive type and energy infrastructure. The decision for or against a particular energy system depends on the individual needs of a customer. The respective area of application, costs, necessary framework conditions and the future viability of the system must be considered. When selecting the right energy system, we examine the following six criteria.

Infrastructure & Vehicle Availability

First, the current energy supply (e.g. photovoltaic systems, filling stations, etc.) in the company is considered. Depending on the energy system, special infrastructure (e.g. space for battery charging stations, larger grid power cables, open spaces for filling stations, etc.) may first have to be created or the existing one expanded.

The point of vehicle availability also plays an important role. Long downtimes due to battery changes, charging processes or maintenance work can cause failures that can be kept to a minimum by choosing the right system.

Areas of application & future viability

The locations (e.g. indoor or outdoor) and conditions (e.g. food industry, chemical industry) of the vehicles are also considered in detail. Not every drive type is suitable for every application. For example, a diesel truck is not the first choice in enclosed halls due to the exhaust gases produced.

When a company invests in a new system, it often has a specific goal. Whether it is to meet society's desire for sustainable supply chains and climate neutrality, to save energy, or to optimize the process in the warehouse. Thus, the future viability of the technology is also an important selection criterion.

Safety & cost-benefit ratio

The topic of occupational safety and thus also driver safety are becoming increasingly important. A lack of knowledge about battery replacement, acid handling and the like can lead to unsightly accidents. Accordingly, many companies rely on technologies that are fast, safe and uncomplicated to use.

In the final evaluation, the acquisition costs (e.g. commissioning, construction or adaptation of the infrastructure) and operating costs (e.g. maintenance, servicing, energy costs) are still decisive. By means of a cost-benefit comparison, we help you find the right energy system for your individual needs.

Funding opportunities for forklifts

Do you want to get rid of the combustion engine or lead-acid technology and switch to more environmentally friendly alternatives, such as lithium-ion batteries or hydrogen? Then you should definitely take a look at the federal government's subsidy programs. The German Federal Office of Economics and Export Control (BAFA) currently offers a program in the field of energy efficiency that can be used for the purchase of new industrial trucks.

Our energy consultants will be happy to inform you about the various funding options and their requirements and support you in the application process.

Frequently asked questions about energy systems

All drive types still have their justification. The selection of the appropriate energy system for the future depends primarily on the area of application of the vehicles. Not every technology is suitable for every area of application. There are specific areas in which the internal combustion engine is still the most economical and technically best solution.

However, in addition to combustion engines and lead-acid batteries, more and more companies are turning to lithium-ion batteries or fuel cells. With the new drive technologies, exhaust gases are avoided and battery replacement or acid handling is no longer necessary. This in turn has a positive effect on occupational safety. As soon as customers' trucks are powered by hydrogen, the fuel cell drive will experience strong growth, as the changeover in the forklift will then take place in the same course.
