Steering Systems
DOLL's advanced steering systems enhance cornering, maneuverability, and reduce tyre wear, crucial for vehicles over 20 meters in length. Systems are tailored to each model series.

Overview of DOLL Steering Systems
DOLL provides precise and reliable steering systems for heavy haulage vehicles, including rigid and friction steering, hydraulic turntable steering, and hydraulic knuckle steering.

Rigid and Friction Steering
Used for minimal maneuverability needs, rigid steering involves the towed unit being drawn by the towing vehicle, while friction steering uses frictional forces during cornering.

Hydraulic Turntable and Knuckle Steering
These systems transfer the turning angle from the towing vehicle to the axles via hydraulic cylinders, offering excellent maneuverability and handling. The knuckle steering system includes a dual-circuit hydraulic system for enhanced safety.

DOLL Panther Features
The DOLL Panther is noted for its resilience, stability, and flexibility in heavy haulage, featuring split axle, hydraulic suspension, and innovative independent suspension.

DOLL Tronic System
This electronic operating and control system uses radio technology for efficient trailer function operation, including a CAN bus system, radio remote control, and visual feedback.

Service and Support
DOLL offers extensive service and support, including spare parts logistics, repair and maintenance, and a 24-hour service network. Training is provided to service partners to ensure familiarity with DOLL vehicles.

Conclusion
DOLL's expertise in steering systems and vehicle technology ensures high-quality, durable, and efficient solutions for heavy haulage needs, supported by comprehensive service and support networks.
