Hand-guided marking machine RP30/50

The Hofmann RP30/50 is a hand-guided indirectly heated thermoplastic screed box machine for repair, rework, intersection marking, and car park surface marking operations. The machine is available in two standard line width configurations — 30 cm and 50 cm — with an adjustable-width chassis that accommodates different screed shoe widths across the full 10 to 50 cm marking width range. Dimensions for the 30 cm configuration are 1,600 mm (L) x 1,000 mm (W) x 1,000 mm (H); the 50 cm configuration is 1,500 mm (L) x 1,200 mm (W) x 1,000 mm (H). Operating weight with glass bead spreader and without gas cylinder is approximately 120 kg (30 cm) and 130 kg (50 cm); without bead spreader, approximately 95 kg and 105 kg respectively. The screed box is indirectly heated via thermal oil, with a gas burner maintaining temperature at the material reservoir, slide runners, and material outlet flap throughout the operation. The slide runners on the screed box closure are made from wear-resistant hard metal alloy. Layer thickness is adjustable at the screed box closure. Chassis contact pressure on the road surface is also adjustable to distribute weight between runners and wheels, allowing light and smooth pushing by the operator.

The indirect thermal oil heating system maintains consistent temperature across the full screed shoe assembly — preventing temperature drops caused by wind exposure or work interruptions that would cause thermoplastic material to stiffen and produce irregular layer thickness or incomplete surface adhesion. The three-wheel chassis design keeps the machine running straight without operator guidance correction during marking passes. The RP30 Klappensatz variant replaces the standard fixed-width 30 cm screed shoe with a sectional flap shoe — individual flap sections of 3 cm to 30 cm total width can be opened or closed independently, allowing complex marking patterns such as tactile guidance markings for the visually impaired to be applied in a single pass. Optional accessories include a battery-powered bead centrifuge (18V, 5Ah), a glass bead spreader with up to 20-liter container, and a tactile marking configuration.

The Hofmann RP30/50 is deployed by road marking contractors for thermoplastic marking repair and rework, stop line and give-way line marking at intersections, car park bay markings, pedestrian crossing refreshes, cycle path symbols, and tactile guidance path markings — wherever a self-propelled machine would be inefficient for the work area size or layout, and where heated screed application is required to meet thermoplastic film thickness and bonding standards.

Leader Infra supplies this indirectly heated hand-guided thermoplastic screed box machine for road marking contractors — delivering adjustable-width gas burner heated screed marking from 10 to 50 cm line width in a 95 to 130 kg three-wheel chassis suited for repair, intersection, and car park thermoplastic marking operations.

FAQ — What is the operational advantage of the Klappensatz sectional flap shoe over the standard fixed screed shoe on the RP30? The Klappensatz sectional flap shoe divides the full screed width into individual independently controlled sections, each switchable open or closed from the machine handle. This allows the operator to apply complex multi-strip patterns — such as the raised dot rows of tactile guidance path markings, or multi-stripe crossings of specific widths — in a single forward pass without requiring multiple passes with different fixed-width screed shoes, significantly reducing marking time and repositioning effort on complex surface layouts.
