2.0 General instructions
2.1 Technical description
The BELUGA, SQUATINA, KOGIA and the ESPADA represent a whole new generation of drive units for
stone cutting. The exceptionally comprehensive modular system offers the flexibility needed today when
performing cutting work in concrete and stone. To achieve this, newly developed high-frequency motor
parts are used in the motor. The frequency range is controlled by the frequency converter from 0 - 1000 Hz
integrated into the Powerbox. The Powerbox can be operated on a single-phase 230 V mains supply as
well as on a 400 V mains supply with up to 12 kW. Our motors automatically detect the correct voltage and
then work at the allowed power rating for the voltage. At 1000 Hz, the rotor reaches a speed of 30.000 min

. A major benefit lies in the exceptional weight / power ratio (motor power output = 8 kW / weight = 12.5 kg
-> 0.64). Using conventional technology e.g. type BBM33extra (motor power output = 2.4 kW / weight =
13.5 kg -> 0.17). This means that the weight of the machine has been reduced fourfold using the high-
frequency technology. Further benefits lie in the stepless speed control. This enables the best speed to be
assigned to each tool diameter in order to attain the best possible cutting speed on the tool. During work,
the speed can be steplessly reduced if you come up against steel reinforcements and thus can be opti-
mised according to the progress of the work. Here, you can run the unit at much higher cutting speeds (At-
tention! depends on the tool) and in doing so, the progress of the job can be speeded up by up to 200 %.
With conventional machines, the torque drops very sharply at the higher speeds and therefore, this ad-
vantage does not apply here.
2.2 Applications
All attachments can be used with drive units, which are fitted with the DR. BENDER quick release system.
If you are using custom-built machines, the details on the quotation and the order confirmation also apply.
When suitable saw blades and drill bits are used, a wide range of materials can be cut:
- Concrete (even with strong reinforcement)
- Sandstone and limestone
- All building materials for solid walls
- Asphalt road surfacing
3.0 Transport and storage
3.1 Transport
Warning
The attachments must be inspected for transport damage after receipt. Any
damage present must be recorded in writing.
3.2 Storage
The storage location should be dry, clean, and at a constant temperature wherever possible. To keep the
lubrication film in the bearings and the seal systems from separating, the drive shaft should be turned
several times manually after a lengthy storage period, e.g. at monthly intervals. The roller bearings of the
devices should be replaced (or re-lubricated) if the period between delivery and commissioning is more
than 4 years. This period will be significantly reduced if the storage conditions are unsuitable.
