Choosing the Right Road and Highway Line Marking Machine
Road and highway line marking is governed by Austroads ATS 4110 (Longitudinal Pavement Marking, May 2021) and the relevant state-body specification (TMR, Main Roads, VicRoads, RTA NSW). The contractor needs current PCCP accreditation under Category B (Class 20 long-run major roads, Class 21 short-medium minor roads, Class 22 audio-tactile, Class 27 removal). The equipment needs to meet ATS 4110 Clause 6 capability: automatic pattern control (skip-line), the ability to mark a double one-way or double two-way barrier line concurrently, dual-angle bead delivery producing similar retroreflectivity in both directions (within 15%), and calibration to achieve required application rates.
Walk-behind ATS 4110 units. Graco LineLazer V 200HS HP Reflective (Honda GX200 6.5 HP, 2.15 GPM, 3,300 PSI, 0.034 inch max tip on 2-gun, dual auto guns plus dual 120 lb pressurised bead tanks, 3/8 inch x 22 ft BlueMax II hose, 189 kg) is the standard council and contractor entry. LineLazer V 200DC HP Reflective Dual Colour adds a second pump for centre + edge in one pass. For councils running smaller-scale public-road work, the LineLazer 130HS Standard (1 auto gun or 2 manual variants) is the entry walk-behind in this collection.
Self-propelled long-line. Graco LineLazer V 250SPS HP Reflective (Honda GX390 13 HP, 2.5 GPM, 3,300 PSI, 0.039 inch max tip, dual 120 lb pressurised bead, 10 mph operating speed, 302 kg, RAC 5 321/425/627 in kit) handles bigger flows and longer runs. Pair with LazerGuide 3000 for highway work where line straightness over distance matters. The V 250DC Reflective Dual Colour adds the dual-pump dual-colour delivery on the same self-propelled unit.
Truck-mount. For state-body highway, regional council fleet, and B-double depot work, the Graco RoadLazer RoadPak module (4-gun capable, belt-mounted with Taper-Lock pulley swap for drive-train matching) is the production unit. Three RoadPak configurations: standard System, HD (heavy-duty), and Tow-Behind T4. Plus the RoadLazer HPS with Dura-Flo XL pump for high-flow protective coating work. Custom GO truck builds add the tray, handrails, stairs, arrow boards, 200-650 kg pressurised bead tanks, and Skip-Line NZ camera and laser layout systems for runway-grade precision (~$300k+ inc GST, 4-month build cycle).
Bead, paint, training. ATS 4110 Annexure B Table B1b mandates 350 mcd/m²/lx dry retroreflectivity for white longitudinal markings within the first 30 days, dropping to 200 between days 365-395, with intervention required below 150. Yellow tracks lower (200/150/100). Achieving and holding those targets requires the right bead dispensing kit (Type B-HR 0.5-1 mm or Type C-HR 0.85-1.4 mm or Type D-HR coarse with adhesive coating, all per APAS 0042) at 50-60% bead embedment in the wet paint film at 350-400 micron WFT for waterborne paint with Type B beads. Every council and contractor purchase includes operator training, on-site commissioning, and the Stripe More Kit + spare Endurance Pump (Graco 246428) + Pump Armour 1 gallon (Graco 245133).
