Hand-guided, self-propelled marking machine H9-1 Serie

The Hofmann H9-1 Series is a family of hand-guided self-propelled road marking machines for small to medium-scale marking operations across a broad range of material types and application technologies. All variants share a common Honda single-cylinder 390 cm³ petrol engine, air-cooled, delivering 8.4 kW at 3,200 rpm, with a stepless hydrostatic drive powering a differential front axle for uniform traction on both straight runs and tight curves. The vibration-isolated engine and compressor unit reduces operator fatigue across extended marking programs. The spray gun bracket mounts on both left and right sides. A rear wheel straight-line lock keeps the machine on course without constant steering input. An optional electronic line-spacing controller (ELC1plus or ELC4) automates gun firing sequences. Optional strobe warning lights are available. An optional ride-on seat trailer (23 kg, adjustable seat position, pneumatic tyres, 900×740×1,000 mm) converts the machine from push-guided to ride-on operation. Six application variants are available — H9-1 Airspray (cold paint, up to 48L single or 2×24L dual-colour, lines 10–60 cm), H9-1 Airspray 2K 98:2 (two-component cold plastic, 670 L/min compressor, 1.0–4.0 wt% hardener stepless), H9-1 Airless (cold paint/2K spray, up to 7.5 L/min pump, 260 L/min compressor), H9-1 Airless 2K 98:2 (1.2–3.0 wt% hardener, static mixer internal mixing, up to 6.0 L/min), H9-1 Airless 2K 1:1 (internal or external mixing, 2×3.5 L/min), and H9-1 Sprayplastik (spray thermoplastic, indirect propane gas thermal oil heating, 50L container, single or continuous double lines, optional pneumatic agitator). Non-Airspray line widths are 10–30 cm; the Airspray variant reaches 10–60 cm. Machine weights run from approximately 250–285 kg (Airspray/Airless) up to 370–400 kg (Airless 2K 98:2 and Sprayplastik). Glass bead pressure containers are available in 20L single or 2×20L dual configuration at up to 1.0 bar. Standard commercial material containers are compatible across all variants without proprietary packaging. The machine is confirmed deployed at the Nürburgring in Germany, Silverstone Circuit in the UK, and in South Africa and Djibouti.

The six application variants of the Hofmann H9-1 Series allow a single machine platform to cover the full spectrum of commonly specified road marking materials — from solvent-borne and water-borne cold paints through sprayable two-component MMA cold plastics at both 98:2 and 1:1 mixing ratios through to heated spray thermoplastics — without requiring separate machines for each material type. This breadth of material compatibility across a common mechanical platform substantially reduces capital investment for contractors who operate across multiple marking specification types, and allows a single machine to remain in deployment across multiple contract types within the same fleet year.

Leader Infra supplies this six-variant hand-guided self-propelled cold paint, sprayable 2K cold plastic, and spray thermoplastic road marking machine series — delivering Honda 8.4 kW hydrostatic differential-drive propulsion, vibration-damped engine isolation, and a ride-on seat trailer option across all variants for versatile small-to-medium scale marking programs globally.

FAQ — What is the operational difference between the H9-1 Airless 2K 98:2 and the H9-1 Airless 2K 1:1, and when would a contractor choose one over the other? The 98:2 variant mixes a large base component with a small hardener addition — the standard ratio for most MMA sprayable cold plastics — and uses a static mixer for internal blending at up to 6.0 L/min. The 1:1 variant handles equal-ratio two-component materials and offers both internal mixing via static mixer and external mixing in the spray fan, at up to 2×3.5 L/min per component. A contractor specifying standard MMA cold plastic road markings would select the 98:2 variant as it matches the dominant market product ratio. A contractor applying equal-ratio specialist materials — such as certain anti-skid coatings or specialist structural marking products — would select the 1:1 variant, with external mixing available where pot-life limitations make static mixer cleaning between passes impractical.
