Sealing over cracks/utility cuts with bitumen band to prevent water ingress.

An optical level sensor detects the presence or level of liquids using light-based sensing. It provides non-contact level detection without moving parts, reducing mechanical wear and routine maintenance demand. The sensor emits light and monitors changes in reflection or refraction to determine whether material is present at a set point. This approach suits tanks and…

Weir preventing foaming overflow back to return.

Sensor tracking contrast for auto steering.

Lamp fitted above the gully boom for visibility during night work. Improves accuracy when positioning the suction hose.

Porous aggregate mix encouraging binder penetration and retention.

Gauge for wet film in transparent coatings.

Structural mount supporting the gully-suction boom at roof level. Designed to pivot for stowage and includes a safety-locking pin.

Gauge displaying hydraulic-oil temperature on the control panel. Prevents overheating and indicates when the system is ready for heavy use.

Valve regulating flow through the hydraulic-oil cooler. Keeps fluid within the 40–70 °C optimum temperature range for long component life.
