- Up to 285 000 Nm
- Turning:
- 227 000 Nm
- Locking:
- 600 000 Nm
The STL Systems are "multi-function" units, all contained within one interface. It is indeed a modular system that you can choose the function(s) needed. All from single, S (Stopping) T (Turning) or L (Locking) functions. Combined dual or triple functions in terms of SL, ST, TL, to a complete STL system can be selected. Each system contain a unique control system that communicate and integrate with superior system for easy operation and control.
- Individual stopping, turning and locking functions
- Dual functions: Stop and Turn, Stop and Lock, Turn and lock
- A complete, turning and locking system
- Control systems designed and/or customized to meet platform unique integration
- Hydraulic
- Electric
- Manual
- Standard or Custom packages
- Shock and vibration approved configurations
- Hand held control units
Whether at sea or based on land, STL Systems give you complete control over your stopping, turning and locking functions.
Stopping, Turning and Locking (STL) systems are precision engineered and fully modular, making it possible to choose from the functions to create a system which fits your application:
- Individual Stopping, Turning or Locking functions
- Dual Functions:
- Stopping & Turning
- Stopping & Locking
- Turning & Locking
- Complete STL-System with all functions
- Fully automatic control
- Semi-automatic control
- Fully manual control
Stopping, index Turning and Locking (SiTL)
Advantages:
- Easy engagement and disengagement even with residual forces present
- Turning function is index turning with hydraulic cylinders
- Controlling can be done fully remotely, locally with push button interface, or as combination of the two controls
- Low maintenance overtime with increased personnel safety
Stopping, continuous Turning and Locking (ScTL)
The electric powered continuous STL could be a preferred selection in low-range to midrange torque applications when a continuous turning operation is required and/or when manual operating has limited possibilities.
Advantages:
- Easy engagement and disengagement even with residual forces present
- Turning function is continuous turning with electric motor and gearbox
- Controlling can be done fully remotely, locally with push button interface, or as combination of the two controls
- Low maintenance overtime with increased personnel safety
Stopping, continuous Turning and Locking (ScTL) with BUEL®
DELLNER BUBENZER’s compact, self contained BUEL® STL systems combine elements from STL with DELLNER BUBENZER’s patented BUEL® electrohydraulic thruster/power package.
Needing no external piping, the systems are compact, easy to install, and with the BUEL® using only half a litre of high performance synthetic oil (compared to up to 30 litres of hydraulic oil in standard hydraulic power units), are cheaper to run and enviromentally-friendly too.
Fully Manual Stopping, index Turning and Locking (SiTL)
The electric powered continuous STL could be a preferred selection in low-range to midrange torque applications when a continuous turning operation is required and/or when manual operating has limited possibilities.
Advantages:
- Easy engagement and disengagement even with residual forces present
- Turning function is indexed turning with fully manual control
- Controlling is done fully locally, with provision for instruments for status detection (interlock)
- Fully independent from external power sources
- Low maintenance overtime with increased personnel safety
