In the material handling sector, electrification is an increasing trend, especially in mobile applications. Electric drives are dynamic, efficient, powerful and above all reliable. They are therefore suitable for forklifts, automated guided vehicles (AGVs) or for lift trucks. ABM Greiffenberger supplies the appropriate motors, gearboxes and electronics from its own development and production - individually adapted to the application. The drive specialist from Marktredwitz is therefore a valued partner of customers with diverse intralogistics applications.
A lot moves in and around a logistics center - and drives are required everywhere. This starts with employees arriving at work in electric buses. Trucks transport goods to the receiving point - here, drives are needed for auxiliary units such as hydraulic pumps, compressors and fans. When the vehicles dock, roller shutter doors open and close so that employees can load or unload. Lift trucks, forklifts or AGVs take the goods to pallet and accumulation roller conveyors, which transport them to the high-bay warehouse. Ergonomic lifting aids for goods handling and machines for cleaning the hall floors are used. "We supply the right motors, gear units, brakes and converters for all these applications - from a single source," explains Michael Lühmann, Head of Sales & Marketing at ABM Greiffenberger. "This makes us a system supplier for complete intralogistics."
The drive specialist offers ready-to-install systems for the mobile sector according to the plug-and-play principle, which are available in modular form within a platform concept. "This allows us to easily combine gear ratios and motor sizes together with brakes and sensors to optimize customer applications. The finished solutions can be integrated into different vehicle types," reports Lühmann. This is not a matter of course on the market.
ABM Greiffenberger can completely cover the functions of driving, lifting and steering in the mobile sector with its solutions. They also meet strict environmental and emission requirements, are particularly safe and allow sensitive movements even at low speeds. "We are responding to a growing market. This is because electrification in mobile applications in intralogistics is increasingly advancing," says Michael Lühmann. Electric drive systems are more sustainable and efficient. They run reliably and quietly, are dynamic, durable and offer safety. It is therefore only logical that electric drives are increasingly being used in many applications.
Wheel hub drives with electric steering
The drive specialist offers three gear unit types for mobile applications - these include the robust wheel hub drives of the TDH series. These are extremely compact because the drive components are integrated into the drive wheel. The user benefits from high static and dynamic contact forces. With the large wheel torques at low speeds, he can use them to maneuver pallet trucks, aerial work platforms, AGVs or cleaning machines with precision and for inclines, for example. "We also offer the wheel hub in an electrically steered version," explains Dipl. Ing. Mayk Krüger, Head of Mobile Drive Technology.
With its low overall height, this version is ideal for forklifts and automated guided vehicles. With the electrically steered wheel hub, the user benefits from precisely controllable and efficient AC motor technology. It delivers up to 300 Nm of torque to the wheel and has a drive torque of 360 Nm. The redundant steering sensor system enables precise steering. The drive is also durable, maintenance-
Bevel gear units: innovative platform concept
With the bevel gear units of the TDB series for wheel sizes of 230 and 254 mm, the system provider has efficient components in its range that are powerful and consume little energy. The ready-to-install systems have a modular design and are available as a platform concept. The complete solution consisting of motor, gear unit and sensors can be easily integrated into different types of vehicles. In industrial trucks, the bevel gear units of the TDB series ensure high gradeability and acceleration. They can be controlled sensitively and dynamically over the entire speed range.
The bevel gear unit is available in three versions - for example with integrated electric steering drive. In this case, the travel motor is vertically mounted in a fixed version. Among other things, the operator benefits from redundant steering monitoring, the highest degree of integration, and great driving comfort with high safety.
ABM Greiffenberger also supplies the bevel gearbox for manual steering. The vertical mounting of the traction motor in co-rotating design is prepared for direct drawbar mounting. This robust and durable solution is characterized by space-saving installation.
"Application-specific steering is also possible, and customers can also combine the TDB bevel gearboxes with their own steering drives," says Mayk Krüger. This makes them suitable for electric power steering systems and they can be controlled via spur gearing. Optionally, a zero position sensor can be fitted to calibrate the steering positions.
Speed detection in this series is via an incremental encoder with up to 64 pulses per revolution. In addition, it is possible to use regenerative AC technology. An electromechanical holding brake is integrated for parking and emergency stops.
Parallel shaft gear unit: quiet and efficient
The flat gear units of the TDF series offer particularly high efficiency, low wear and quiet running even under heavy loads. "We achieve this via the highly toothed spur gear technology," describes Lühmann. The gearboxes are suitable for use in pallet trucks and three-wheel forklifts, among other applications. ABM manufactures the gearboxes from die-cast aluminum. This enables customer-oriented solutions with a good price/performance ratio at the same time. The design and the material specially adapted to the application make the 200 mm and 230 mm sizes light and stable. Speed is recorded via incremental encoders with up to 64 pulses per revolution.
System supplier with high development competence
ABM Greiffenberger scores with a lot of know-how and experience in the development of application or customer specific drives as well as with its platform concept. With this, the customer quickly receives a cost-optimized solution. "But we can also respond very specifically to customer requirements," says Krüger. "This means we are not a standard supplier and offer our customers measurable added value."
One example of individual developments is an electric differential axle for forklifts and transport systems. Precisely adapted to the application, the differential axle has optimized interfaces and can thus be easily implemented in the vehicle.
All products, motors, gearboxes as well as the appropriate electronics, are supplied by ABM from a single source. Additive manufacturing allows even complex prototypes to be produced at short notice.
"Our drives offer high performance and system availability," emphasizes Lühmann. This is especially important in material handling, because the vehicles are often in two- or three-shift operation. Reliability is extremely relevant here. Operators therefore rely on drives that are maintenance-free, robust and durable. "We are consistently pursuing our goal of not only supplying high-quality drive solutions, but also supporting our customers as partners with engineering and manufacturing expertise," Michael Lühmann promises.
