With our agile electric forklift trucks, you can maximise your throughput performance in narrow-aisle warehouses. 3-phase AC motors combine impressive performance with minimal consumption. You also have the choice between innovative Lithium-ion technology or tried-and-tested lead-acid batteries.
Our agile electric forklift trucks shine in warehouses offering little room to manoeuvre. Thanks to their small and compact design, these trucks can easily navigate even the narrowest of aisles. The trucks are most at home on level indoor floors, but can also handle outdoor applications with ease. As a further benefit, the mast of the electric forklift trucks is ideal for both racking and stacking and can reach lift heights ranging from 2300 to 7500 millimetres. The capacity of the trucks is up to five tons. In daily use, your drivers will enjoy the many benefits offered by our electric forklifts, including extra seat comfort, a perfect all-round view and comprehensive assistance systems to protect the operator, load and warehouse.
Our innovative 3-phase AC technology also delivers a number of advantages. It ensures dynamic handling and maximum throughput performance, even under heavy loads. And increased performance does not necessarily mean greater consumption: Thanks to regenerative braking, for instance, 30 percent of the energy is fed back into the battery. This welcome energy boost allows our electric forklift trucks to complete even more work on a single charge. Our 3-phase AC motors also require very little maintenance, thus lowering your operating costs.
The right battery for your electric forklift truck depends on your individual requirements. Our pioneering lithium-ion technology offers rapid charging times and requires virtually zero maintenance. Moreover, our lithium-ion batteries last up to three times longer than conventional batteries. If you already have one of our electric forklift trucks, it can be easily retrofitted with lithium-ion power.
Our tried-and-tested lead-acid batteries on the other hand, are all about stamina. With these batteries, you benefit from our 2Shifts1Charge guarantee, which is unrivalled in the logistics sector: Our electric counterbalance trucks can complete two consecutive shifts without the need for battery replacement or top-up charging. This saves you time, energy and costs.
The ETR pantograph reach truck forklift series runs two shifts on one battery charge, guaranteed, allowing your operators to maximize their workday. Experience the industry-exclusive technology and world-class efficiency.
Electrically powered industrial trucks such as forklifts and pallet trucks require a drive battery for operation. These days, depending on the vehicle, these are either lithium-ion, lead-gel, nickel-cadmium or iron-phosphate batteries. In all these battery types, electrical energy is converted into chemical energy via a chemical process in the cells.
Batteries for electric stacker trucks and electrical pallet trucks are galvanic elements in which conductive objects are electrically separated. As such, each battery consists of individual cells connected in parallel.
Direct current is required to recharge the battery. The battery charger draws three-phase or alternating current from the mains. This transforms the mains voltage to the required battery voltage and rectifies the current. In the process, electrical energy is converted into chemical energy. The electrons detach from the anode, the original charge gradient is restored, and the acid density increases.
In order for the batteries to reach the nominal voltage required for the operation of forklifts and industrial trucks, several battery cells are connected in series to form the principle of a traction battery.
The battery technology for forklift trucks and industrial trucks described above is known as a traction battery. This differs from conventional starter batteries, used mainly in cars or for IC engine-powered forklifts. Starter batteries are primarily designed to deliver a high amount of electricity quickly, in order to start an internal combustion engine of a car or diesel forklift.
The principle here is the series-connected rows of individual battery cells. Since each cell has a nominal voltage of 2 volts, voltages add up when cells are connected in series. For example, this results in an operating voltage of 48 V for an electric lift truck with 24 x 2 volt cells. The cell types result from the number of plates in a cell and the forklift battery capacity is specified in Ah.
In a lead-acid battery, the anode consists of lead and the cathode of lead oxide. The electrolyte used is sulfuric acid diluted with distilled water. These types of batteries are powerful and significantly cheaper than lithium-ion batteries.
Due to comparatively long charging times and a low energy density, they are ideal in the 1-shift system and for occasional use industrial trucks. However, if electric forklifts or pallet trucks are used in high-performance warehouses, it is better to use the more powerful nickel-cadmium or lithium-ion batteries with a better forklift battery life.
Lead-acid batteries have other downsides. When charging, water in the battery cells evaporates and must be topped up regularly. You should check the electrolyte level no sooner than half an hour after charging is complete. If there is no longer enough solution in the cells, they must be refilled with distilled, demineralized water. In addition, the water level must be checked at least once a week.
Lead-gel and fleece batteries are maintenance-free. This means battery water refills are not required over the entire service life. The cells are sealed gas-tight, so there are no bad smells from hydrogen gas.
Nickel-cadmium batteries (Ni-Cd batteries) are more powerful and easier to handle than lead-acid batteries. With potassium hydroxide used as a catalyst, the overall cell stability is higher than that of lead-acid batteries. There is only minimal self-discharge and higher charging and discharging currents are generated. These batteries are also suitable for intermediate charging, making them ideal for use in industrial trucks in a multi-shift operation. Unlike lithium-ion, Ni-Cd batteries are also significantly less sensitive to temperature and operate better in extreme temperature ranges from -40 to +50C.
Lithium-ion batteries belong to a new generation of battery technology for forklifts and lift trucks. These powerful batteries have a high energy density, enabling them to carry high currents, and are comparatively compact. In lithium-ion batteries, ionized lithium atoms move in anhydrous electrolyte or polymer between a positive electrode made of metal oxide and a negative electrode made of graphite. Nonwovens or polymer films serve as separators.
The battery technology has a barely measurable memory effect and, with care, a long service life. In addition, unlike lead-acid batteries, they can be charged at any time. The shorter charging times also make them ideal for use in environments with multi-shift operations and high handling rates. Lithium-ion batteries require less frequent recharging thanks to their higher efficiency, with energy being recovered through braking. However, due to the temperature sensitivity, this can currently only be fully exploited for indoor electric stacker trucks.
