V

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.

LED lighting kit improving visibility of sweep gear at night. Standard retrofit on many UK fleet upgrades.

Sweeping guided by AI vision.

Laminated sheet listing daily walk-round checks. Mandated by many UK councils for pre-shift vehicle safety inspections.

Camera aid that follows pre‑marks to keep applicator on line.

Extendable mirror enabling checks under the chassis. Allows safe inspection without crawling beneath the vehicle.

Rechargeable torch issued to each operator for pre-start checks. Guarantees consistent inspection lighting even in poor daylight.
