Narrow, Manoeuverable Machine H16-3

The Hofmann H16-3 is a narrow, manoeuvrable ride-on road marking machine with a five-technique material capability, designed for contractors who need compact dimensions combined with broad material flexibility. The engine is a Kubota water-cooled four-cylinder 1,500 cm³ diesel delivering 26.2 kW at 3,000 rpm (EU Stage IIIA / US EPA Tier 2), with a turbo diesel option available at 33.0 kW under the same emission class. The two-cylinder compressor delivers up to 1,000 L/min at 6 bar. A 70L glass bead container is fitted as standard. Overall dimensions are 3,950×1,325×1,650 mm, with the narrow 1,325 mm width being a defining attribute for access on restricted carriageways. Hydraulic wheel motors provide stepless speed control; a hydraulic multi-disc parking brake holds the machine on gradient.

The Hofmann H16-3 supports five application techniques from a single chassis: cold paint (up to 225L), screed-box or sprayable 2K cold plastic (up to 225L), screed thermoplastic via pull-shoe or open screed box (up to 200L), and spray thermoplastic (up to 200L). Stochastic 2K cold plastic application with a spike roller for anti-skid surface profiles is also supported. Line widths are 10–50 cm depending on equipment. Application units are positioned at the rear of the machine for clear operator sightlines during all marking passes. An optional supplementary cold paint container (24L or 48L) mounts alongside the main material tank for hand-spray work at the same location. Optional ELC1plus or ELC4 electronic line-spacing controllers and a reversing camera are available. The machine is confirmed deployed at the FIFA World Cup 2022 stadium in Al Wakrah, Doha, Qatar.

The long wheelbase and play-free front wheel steering system give the H16-3 stable straight-line tracking at marking speeds, which directly determines whether successive parallel lines remain parallel over long runs. A short wheelbase machine with steering play accumulates small heading errors with every correction, producing visually non-parallel lines on long road sections — a critical quality failure on dual carriageway lane marking contracts where line parallelism is measured and specified.

Leader Infra supplies this narrow five-technique ride-on road marking machine for cold paint, 2K cold plastic (flat, stochastic, and sprayable), screed thermoplastic, and spray thermoplastic — delivering Kubota 26.2–33.0 kW diesel power, 1,000 L/min compressor, and 10–50 cm line widths in a 1,325 mm wide chassis for versatile road marking programs globally.

FAQ — What is the practical difference between the standard 26.2 kW Kubota engine and the 33.0 kW turbo diesel option on the H16-3? Both variants use the same 1,500 cm³ four-cylinder Kubota block under EU Stage IIIA / EPA Tier 2 emission certification. The turbo diesel adds approximately 26% more power output, which becomes significant when the machine is operating heavy thermoplastic or 2K cold plastic configurations — where the combined weight of a full 200–225L material container, heated equipment, and hydraulic loads puts a heavier demand on the engine. Contractors specifying the machine primarily for cold paint or light material applications may find the standard engine adequate, while those running thermoplastic or 2K cold plastic programs at full container capacity, particularly on uphill carriageway sections, would benefit from the turbo diesel’s additional reserve.
