The 817 Electro Battery battery-powered electric material handler is the first of the freely movable battery-powered models that SENNEBOGEN will be adding to its electric range in the future. Thanks to dual power management, these models continue to offer the advantages of cable-based electric material handlers.

Emission-free electric material handlers have been available in a wired form for many years. SENNEBOGEN has been building electric material handlers, which are used stationary or with limited mobility due to a cable, and provide a solution for a wide range of applications. Pure battery-powered devices already on the market have proven to be disadvantageous so far due to the limited operating time of the batteries. SENNEBOGEN's 817 Electro Battery mobile electric material handler with battery technology combines the advantages of both solutions. With the SENNEBOGEN battery-powered material handler, operators can continue working even when it is connected to the main power for charging.

In main power operation, dual power management ensures that the power supply from the mains is used for the work movements, while the excess power fed in also recharges the batteries so that the machine can then work independently again. With an assumed 2,000 operating hours per year and energy generation from renewable energy sources, the battery-powered material handler saves an average of 31,800 kg of CO2 per year compared to its diesel-powered counterparts. In the future, the battery option will be available for the entire electric series of the 817 to 825 models.

Dual power management enables zero-emission mobility

The battery-powered version of the SENNEBOGEN 817 E electric material handler with a nine-metre reach and an operating weight of 18 tons combines the advantages of two machine concepts. If the material handler is connected to the main power, it uses the wired power supply for the work movements without restricting the freedom of movement of the uppercarriage and equipment. Because the charging power is supplied to the undercarriage, the machine can continue to swivel and work 360 degrees. If more power is supplied to the machine than it consumes, this is used to charge the batteries at the rear. If the main power connection is disconnected, the 817 Electro Battery automatically detects this and works autonomously in battery operation with the same performance data. Depending on the power requirement, the battery pack enables working times of six hours without recharging.

If the machine is in a working position for one hour it can be connected to the power supply via a standardized CE plug and charged without having to stop work. The capacities of the battery are easily charged so that the machine can be operated continuously over a complete shift and does not need to be switched off for charging.

Battery technology for every operation

The machine also impresses with its practical design. Thanks to the CEE 63 A connector system, the 817 Electro Battery can use the existing industrial company infrastructure. Investments in expensive charging stations can be avoided because of the 44 kW onboard charger. Charging the batteries at any location is also an option, as a simple industrial socket is sufficient.

Current peaks when working with the machine can be avoided via peak shaving, i.e. if more power is required during combined movements and a full grab, this can be covered by the battery. The connected load is thus reduced to 44 kW without further restrictions. The integrated power electronics also ensure a gentle motor start that is particularly gentle on the mains power grid.

SENNEBOGEN's high-voltage battery systems, which were developed for off-road applications and are already used in many e-mobility applications, are also used for the batteries themselves with 3,000 full charge cycles guaranteed.

Reduced service requirements of the SENNEBOGEN 817 E electric material handler

The battery model offers the advantages of SENNEBOGEN's electric material handler in terms of operator comfort and service. All applications in the hall will be emission-free in the future. The machine operates with less vibration and noise, does not need to be refuelled, and has reduced service requirements because there is no need to change the engine oil and other components found in diesel machines. The operator can conveniently see the charge level indicator via the SENCON control system, does not have to carry out any separate settings even if the power supply is changed, and therefore does not come into contact with the high-voltage technology used in normal operation. The dual power management system automatically detects the energy source and switches to the corresponding working mode automatically. In addition to regular diagnosis, the machine detects faults and interventions in the high-voltage system and then switches off in a controlled manner.

The premiere of the 817 E Electro Battery will take place at IFAT in Munich.
