The Hill AWS (Automatic Warning System)
Advanced fault detection
Following extensive research we have developed a product that continuously monitors the hydraulic system of the coupler, helping to prevent common failures and incidents.
AWS actively monitors the excavator and coupler hydraulics to ensure they they are functioning correctly. Advanced early warning is given to indicate any changes in system performance ahead of conventional signs of failure, such as external oil leaks or loss of coupler engagement forces. The sophisticated AWS hydraulic solenoid monitors not only pressure, but critically oil flow. Possible problems are identified long before they become visible to the operator.
The valve is connected to the control system, which triggers an audible warning. This alerts the operator and all persons at risk in front of the machine.
AWS has been designed for excavators fitted with any type of hydraulic coupler, regardless of their manufacturer.
AWS Detects & alerts:
- Internal hydraulic oil leaks, not visible externally, for example the seals within the coupler cylinder.
- External hydraulic oil leaks in cylinders or hoses
- Faulty solenoid valves
- Failure of the primary engagement system
- Incorrect use due to insufficient operator training
The Hill ECS (External Coupler Sounder)
Alerting individuals in the area that an attachment change is taking place.
Using the same external sounder as the superior AWS system, the ECS monitors coupler pressure only, alerting individuals in the area that an attachment change is taking place, without the constant monitoring of the excavator and coupler hydraulics.
ECS Detects & alerts:
- Major external hydraulic oil leaks in cylinders or hoses
- Complete failure of the primary engagement system
- Incorrect use
The Hill Reverse Hose system
A system to maintain correct hose positioning
It’s long been an issue that coupler hoses are vulnerable due to their location. They can easily become entangled in the excavator linkage, causing rapid wear and tear, often causing major damage to the hoses.
But, when the hoses are positioned between the bucket link they can’t be damaged.
They can easily become entangled in the excavator linkage, causing rapid wear and tear, often causing major damage to the hoses.
The only logical solution is to prevent the hoses from moving out of position in the first place.
The Hill Reverse Hose System consists of a specially designed manifold block and hoses encased in a protective sleeve that ensures they stay in the correct position at all times.
