Mobile Crane SGC 120
Driverless container transport system AGV
Secondary controlled drive, automated transport operation, position determination via sensors in the road bed. High positioning accuracy.
- load capacity: 50t
- power: 275 kW
- speed: 25 km/h
Torsional load test bench RWTH Aachen
Dynamic coupling test bench, consideration of the torsion angle of both coupling halves, energy recovery via the load unit.
- Feed-forward control
- torsion angle measurement
- energy recovery
Highly dynamic real crash test bench
The required acceleration power of 530 kW can be lowered to only 30 kW primary power due to the use of hydraulic accumulators.
- energy recovery
- power reduction
- rotational speed difference < 0.3 km/h
Driverless container transporter CT60
More than 200 vehicles in use at the container terminals in Rotterdam and Hamburg. Position determination via sensors in the road bed.
- load capacity: 60t
- positioning accuracy < 1cm
- high speed accuracy irrespective of loading
Centrifugal force – simulation test bench
For 3000 kW acceleration power only 800 kW primary power required. Up to 60% of the energy is recovered.
- moment of inertia 35000 kgm2
- 24 * A4VSO250DS1 units
- 30 times acceleration due to gravity attainable
Telecommunication cable-laying ship
The ship pulls a plough, opens the sea bed, lays the cable in and closes the trench. The high dynamic of the secondary controlled system prevents the break away of the plough rope while get stuck.
- Down to 1500 m water depth
- 4 * 355 A4VSO
- 130 t load capacity
Tensioner drive of a pipeline-laying system
Up to 16” rigid or flexible pipelines are lowered to a depth of 2500 m with the help of two series-connected tensioners.
- load capacity: 2 * 275 t
- laying depth up to 2500m
- laying of pipelines up to 16”
Active heave compensation
Secondary controlled drives work together with conventional hydrostatic drives in a single system. While the conventional hydrostatic drive carries out the lifting function, the superposed secondary controlled drives perform the active heave compensation.
- compensation value > 90%
- load capacity 160t
- working depth of up to 2100 m
Deep sea winch
Conventional winch systems with their heavy steel ropes reach their limits at depths greater than 2500 m. Synthetic fibre ropes, however, are lighter, although more difficult to handle due to their stretching. With the aid of six secondary controlled drives this problem has been solved successfully for the first time.
- synthetic fibre rope
- loading capacity 50 t
- working depth > 2500 m
Crane drive for oil tank platform
Both mounted cranes are used for transferring relief supplies on and off cargo ships. Without the active heave compensation loading and unloading would be impossible. The hoist gear is solely secondary controlled. The slewing gear is also secondary controlled but is additionally supported by a conventional hydraulic rotating drive.
- active heave compensation with overload protection
- load capacity 5 t
- lifting speed 100 m/min
Underwater robot winch drive
The secondary controlled winch drive lowers the supply unit with the underwater robot (ROV) to the sea bed. In active heave compensation mode the ROV undocks and can be remotely controlled for maintenance or monitoring operations.
- active heave compensation with energy recovery
- load capacity 20 t
- lifting speed 140 m/min
Bow thruster for towboats
The integration into an existing hydraulic supply system on board is a cost-effective alternative to conventional bow thruster systems. The power limitation of the secondary controlled drive allows maximum utilization of the primary station.
- 300 kW bow thruster
- retrofit project with integration into an existing hydraulic system
- independent parallel operation with other drive systems on board
Universal Hydraulic Test Bench
The test bench can be operated at 160 kW from both drive and load sides. The variety of configuration possibilities enables a multitude of tests to be carried out, ranging from component tests right through to efficiency measurement tests of complete systems.
- 160 kW installed power
- Energy recovery of up to 60%
- Flexible configuration allows different test possibilities
Rail Milling Machine
The rail milling machine will be used for the maintenance reprofilinig of rails. For this the complete rail milling machine must be driven in speed synchronisation.
- Secondary controlled drive of two milling wagons
- Synchronisation of 4 chassis with 8 secondary controlled units
- Traction control over 66 m train length with 300 t total weight
- At 0,3 – 2 km/h from 0,3 up to 10 mm milling depth
