Buel® G
The BUEL® Model G is a new family member of the DELLNER BUBENZER brand BUEL®. It is a compact thruster to feed active or passive hydraulic brakes and emergency brakes. It is also suitable for small capacity hydraulic cylinders. Operational pressure can be up to 250 bar.
- Compact design
- Fail safe principle
- Variable tank capacity, small filling quantity
- Use of bio-degradable oils possible
- Redundant valve system
- Energy saving by limited duty cycle
- Automatic compensation of pressure losses, by short time actuation
- Hydraulic parts protected inside the housing
- 2 pressure outlets
- Internal generation of the control voltage for valves and sensors
- Overload protection by monitoring of the working pressure
- External manual release incl. “dead-man-handle”
- Integrated bursting pressure protection
- Options for additional functions and monitoring
Electrical design All BUEL® thrusters are operated with 3-phase voltages between 220 V to 690 V @ 50 Hz or 60 Hz.
Protection class All electric components of the BUEL® thrusters are located inside, for best protection against environmental influences. BUEL® thrusters are rated IP 65. Protection class IP 67 is possible as an option.
Operating modes BUEL® Model G thrusters are designed for intermittent duty, independently from the required operating mode of the drive installed. There is no limitation of duty cycle. The motor is switched off after reaching the working pressure. In case the working pressure is not reached within 4 seconds, the motor is switched off internally.
Ambient temperature range BUEL® 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 G 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 oils can be used as an option.

These rail clamps are storm brakes suitable for high forces. They are self-blocking type; in case a force acts on the crane and tends to put the same into motion, they press on the rail sideways.

The DH hydraulic power packs deliver pressure up to 200 bar and can be delivered with optional hydraulic cabinets and electrical terminal boxes.
The EBA is a powerful drum brake with braking torques from 24 (ft-lb) to 9000 (ft-lb) that meets AISE (TR11) & NEMA (ICS 8) standards.
The EBH series is designed according to DIN 15435. This design is very compact and can be used in tight motor gearbox combinations.
The EBN series is designed according to DIN 15435 and has been in use in various industries for decades. EBN-2St modification: the drum brakes solution for Bridges and Sluice Systems
The FKE is best suited for applications with light starting and stopping loads. It is also commonly used as a slip clutch or tension brake within light horsepower and torque applications.
The FKR is often referred to as a coupling, as its expanding neoprene rubber facing engages the interior diameter of the drum directly. The resulting friction generates significant torque within a small package.
The FK is well suited as a clutch or brake for a variety of high speed and low to medium torque power transmission applications where high heat generation is not a factor.
The FKT is well suited for applications with the most demanding equipment where severe clutching and braking is required.
The FM is designed and manufactured for marine applications, mainly for use on diesel-driven reduction gears.
Our hand pump can be used to simply activate the Dellner brake calipers. It also acts as a back up system for the primary pressure supply system.
The hydraulic rotary actuator is a device which transform hydraulic power (pressure and flow) in mechanical power: torque and angular speed.
A hydraulic rotor lock offering up to 250 bar pressure with an activation time of 60 seconds.
We offer three models of the JHS-RLH-240 hydraulic rotor lock – the GL Type Certified JHS-RLH-240, the JHS-RLM-240 and the JHS-RLH-240-154. All these locks deliver up to 250 bar pressure with an activation time of just 35 seconds.
Manually activated rotor lock used for safety purposes during maintenance operations to stop the rotor mechanically. The maximum lateral force is 6400 N and the standard stroke is 95 mm. Other strokes are available upon request.
These couplings are for use in application with high dynamic loads. Damping of peak torques and vibrations as well as electrical insulation between motor and gearbox are further reasons for the use of this coupling type.
These couplings are for use in machinery where a torsionally rigid torque is required, especially on frequently varying loads and speeds.
