The SKF HCC (Hose Connection Control) system is a vital safety component for automated lubrication systems, particularly in heavy industries such as mining, construction, and large-scale manufacturing. In these environments, the failure of a single lubrication hose can lead to catastrophic bearing damage, unplanned downtime, and significant environmental cleanup costs. The HCC system provides a proactive solution by continuously monitoring the connection between the main pump unit and the individual lubrication points.

Reliable Failure Detection

The core principle of the HCC system is its ability to recognize the electrical or physical continuity of the hose connection. Unlike pressure sensors, which might give false readings due to grease viscosity changes or temperature fluctuations, the HCC specifically detects if the hose has physically failed or detached from its fitting. This is achieved through integrated conductive elements or smart sensors that trigger an immediate alarm if the circuit is interrupted, regardless of the system pressure or grease flow state.

Engineered for Extreme Conditions

SKF Lubrication Systems Germany has designed the HCC to withstand the toughest industrial conditions. The units are encased in rugged housings with high IP ratings (IP67 or IP6K9K), ensuring they remain functional even when exposed to high-pressure cleaning, corrosive lubricants, and extreme vibrations. This makes the HCC system ideal for mounting on excavator arms, crushing plants, or wind turbine bearings where manual inspection is difficult or impossible.

Key Features and Benefits

• Instant Alarm Feedback: Provides real-time notification to the machine PLC or operator display, allowing for immediate corrective action.
• Prevention of Lubrication Failure: Ensures that grease actually reaches the bearing, rather than leaking into the environment.
• Reduced Environmental Impact: Minimizes the risk of grease soil contamination by stopping the pump or alerting operators as soon as a leak is detected.
• Modular Integration: Can be easily integrated into existing SKF or Lincoln lubrication systems with minimal reconfiguration.
• Versatile Mounting: Supports monitoring of multiple hose lines simultaneously depending on the control unit configuration.

Typical Applications

• Construction Machinery: Monitoring lubrication lines on excavators, wheel loaders, and tunnel boring machines.
• Mining & Quarrying: Ensuring reliable grease delivery to high-vibration equipment like crushers and screens.
• Wind Energy: Protecting critical pitch and yaw bearings where hose access is restricted.
• Automated Manufacturing: Safeguarding precision machines and conveyor systems in automotive assembly lines.
