About HKS
HKS Dreh-Antriebe GmbH manufactures hydraulic rotary actuators and related systems. Its official contact information lists facilities in Wächtersbach-Aufenau and Neukirch/Lausitz, Germany.
What does HKS manufacture?
The construction-equipment range includes three distinct positioning products: XtraTilt for tilting, RotoBox for continuous rotation and TiltRotator for combined tilt and rotation.

Choosing a configuration
Choose between tilt-only, rotation-only and combined functions before comparing individual models. Mounting arrangement, oil feedthrough and model-specific hydraulic requirements affect the complete installation.
Before selecting a HKS configuration, confirm the exact carrier, mounting interfaces, installed weight, hydraulic requirements and control functions with the manufacturer or supplier.
Product range in context
The HKS attachment range includes hydraulic rotary actuators, tilt units, hydraulic rotators, and tiltrotators. Typical applications include excavation and digging, forestry and tree care, grading and site preparation, material handling and lifting, and scrap, waste and recycling. Compatibility depends on the exact attachment model, carrier size, mounting interface, hydraulic system and intended duty cycle. Compare the relevant product family first, then verify model-specific dimensions, weight, oil flow, operating pressure and control requirements for the machine and job.
What to compare within the HKS range
Within the HKS range, specifications differ by product family. Compare the main dimensions, carrier requirements, hydraulic demands and working limits shown below before treating two models as direct alternatives.
| Product area | Typical role | Key specification checks |
|---|---|---|
| Hydraulic rotary actuators | Controlled rotary or tilting movement. | Torque, rotation angle, allowable loads, hydraulic demand and mounting dimensions. |
| Tilt units | Adding lateral tool articulation without full rotation. | Tilt angle, service weight, coupler interface, hydraulic plumbing and added build height. |
| Hydraulic rotators | Continuous rotation of grapples and handling tools. | Lifting load, torque, axial and radial loads, mounting pattern, ports and through-channels. |
| Tiltrotators | Combining continuous rotation with tilting for excavator tools. | Machine weight class, coupler standard, control system, hydraulic installation, tilt range and total installed weight. |
Where HKS products fit
Application context matters for HKS equipment because the same attachment category can be configured very differently for different jobs. Other applications can place different demands on geometry, wear protection, hydraulic capacity, cycle time and carrier stability, so the intended duty should be defined before selecting a model.
- Excavation & digging: bucket or tool geometry, breakout requirements, coupler dimensions and machine balance should be matched to the material and trench or loading task.
- Forestry & tree care: tree size, cutting or gripping capacity, rotation, hose routing and the carrier hydraulic system determine practical suitability.
- Grading & site preparation: working width, controllability, visibility, attachment height and fine movement influence accuracy and productivity.
- Material handling & lifting: rated loads, load centre, gripping geometry, rotation and the carrier lifting chart must be checked together.
