Buel® S
The BUEL® Model S is a brand new family member of the DELLNER BUBENZER brand BUEL®. It is designed for wheel brakes on rail mounted cranes, where high pulling forces for mechanical wheel brakes are required. The patented cylinder system generates pulling forces up to 40.000 N. It has a robust, but also compact design for rough environmental conditions.
- Pressure generation by centrifugal gear pump
- Energy saving by intermittent duty
- Fail safe principle
- Redundant valves
- Terminal box with control board
- Automatic pressure drop compensation
- Low heat generation
- Huge temperature range in standard execution
- Little oil volume
- Low ecologic risk
- High protection category
- Infinitely variable setting time
- Hand pump with shut-off valve
- Low weight, excellent mass/performance ratio
- Limit switch release control off the shelf
Electrical design All BUEL® Model S units are operated with 3-phase voltages between 220 V to 690 V @ 50 Hz or 60 Hz.
Protection class The electric components of the BUEL® Model S thrusters are located inside, for best protection against environmental influences. BUEL® thrusters are rated IP 65.
Protection class IP 67 is available as an option.
Operating modes BUEL® Model S thrusters are designed for intermittent duty, independently from the required operating mode of the drive installed. There is no limitation of the duty cycle.
After reaching the working pressure, the motor is switched off. In case the working pressure is not reached within 4 seconds, the motor is switched off internally.
Ambient temperature range BUEL® Model S thrusters are suitable for ambient temperatures between -30°C to +60°C. For deviating ambient temperatures, please contact us for support.
Protection against moisture For applications in maritime or tropic environments, the optional use of a small heater to protect the motor windings from moisture is recommended.
Heater voltages can be:
- 110 to 120 V AC 50 Hz or 60 Hz
- 220 to 240 V AC 50 Hz or 60 Hz
Hydraulic media BUEL® Model S thrusters are filled with a high performance synthetic oil, type Fuchs Titan CHF 11S. This oil insures a trouble-free operation in the entire temperature range, indicated above.
Biodegradable oil is available as an option.
