H
Hydraulic Return Filter
Filter protecting components from contamination.
Hydraulic-Flow Divider
Valve dividing oil flow between broom and suction systems. Maintains balanced performance when multiple circuits operate simultaneously.
Hot Box (Thermo)
Insulated box keeping pre-formed thermoplastic warm on site.
Hydraulic-Line Quick Coupler
Standard ISO-type coupler allowing hoses to be connected or removed rapidly. Speeds up broom-arm replacement and reduces oil spillage.
Hot Melt Filter Basket
A hot melt filter basket is a high-temperature filtration component used within thermoplastic road marking systems. It filters molten material before it reaches applicators or nozzles, helping reduce blockages and flow disruption. Filter baskets are inspected and cleaned as part of routine equipment checks, particularly where material contamination or reheating affects quality. This component is…
Hydraulic-Oil Sampling Kit
Portable kit for drawing oil samples safely from pressurised lines. Enables predictive-maintenance analysis without downtime.
Hot Pressure Test
Pressure test at temperature to confirm seals.
Hot Tape Markings
Preformed thermoplastic sheets/tape applied with heat for quick symbols/legends.
Heated Spray Bar
Bitumen sprayer bar fitted with electric or fluid heat tracing. Ensures all nozzles deliver binder at a constant temperature for uniform coverage.
Hopper Overload Alarm
Sensor-based alarm that sounds when the hopper reaches its maximum safe load. Prevents overfilling which can reduce suction efficiency or damage hydraulic rams.
