7 Benefits. Zero Compromise.

RO50 is the hero product. Every benefit is engineered for commercial towing — with 40 mm variants covered in the comparison below.

Self-Centering

Benefit 7

Benefit 1

Modern Design

Minimalist. Premium. Timeless.

Holistic design concept with ROCKINGER's signature look
Proven rotating coupling pin for 40 mm and 50 mm
Opens at rotated funnel in all possible angles
Simplified retrofit system

Benefit 2

Modular Architecture

One product. Endless safety, comfort & maintenance upgrades.

One-fits-all upgrade kits across product lines
Remote indication, remote control, LubeTronic, Drawbar Finder
Same functionalities with fewer article numbers for spare parts
From basic to high-class coupling without extra effort

Benefit 3

Ergonomic Hand Lever

Comfortable operation with optimal force transmission.

Wider handle for improved power transfer
Easier opening compared with standard round handle
Radius optimization for smoother manual operation
Reduced physical strain for drivers

Benefit 4

Reinforced Funnel

Extra strength for safer, tougher performance.

Up to 5 mm strengthened wall thickness (max. 11 mm) on 50 mm
Radius optimization to optimize force transmission
Proven technology to open with rotated funnel at all angles

Benefit 5

Damage Protection

Maximum protection even under the highest demands.

Innovative bumper design protects the coupling mechanism
Effective force absorption in case of towing eye impact
Replaces direct force transmission to the mechanism on legacy designs
Helps prevent costly repairs from misalignment and impact

Benefit 6

Built-in Security Devices

The most reliable indication that the hitch is securely closed.

Built-in technology for security devices
Reliable status indication at any time
Supports rear-end and in-cab remote indication options
Clear feedback for drivers, fleet managers, and workshops

Benefit 7

Compact Self-Centering Funnel System

Reliable automatic centering with minimal installation height.

Well-known ROCKINGER self-centering system
Lowest profile on the market
Even more reliable thanks to the Pre-Mount concept
Crucial for vehicle builders with tight installation space
