Air knife producing vortex sheet.

Resistance to flow; controlled by temperature and flux content for sprayability.

A viscosity cup is a measuring tool used to assess the flow characteristics of liquids such as paints, binders, or sealants before application. It provides a quick field check so material condition aligns with specification and equipment settings. The cup is filled and allowed to drain through a calibrated opening. Drain time is used as…

Metal cup used to measure bitumen or paint viscosity. Ensures fluid meets specification before spraying.

A viscous coupling is a mechanical device that transmits torque between rotating components using a viscous fluid. It provides smooth, progressive torque transfer as speed differences occur between the driving and driven components. As slip increases, fluid resistance rises and torque transfer increases, helping reduce shock loading and vibration compared with rigid couplings. Viscous couplings…

Thermostatic fan coupling on chassis engine.

Recorded video stream for QA evidence.

Camera system observing shoes/nozzles.

Port to momentarily increase suction.

Valve adjusting hydraulic-oil flow for broom circuits. Gives the operator precise control of broom speed from the cab.
