A decoupled battery-powered trailer treats track sections independently, improving maintenance flexibility while keeping operation emission-free.

Gear pumps and a mixer enable continuous ballast adhesive spraying with controlled ratios, uniform coverage, and precise penetration depth.

A charged onboard energy store lets a decoupled trailer wagon power its own traction and treatment devices for flexible, emission-free track work.

Pivoting front and rear assemblies with actuators control pitch and roll to keep boom lifts stable and maintain traction on uneven slopes.

Pivoting front and rear leveling assemblies keep the chassis level on uneven slopes, improving boom lift traction and stability.

Hydraulic multi-gate control enables real-time ballast placement across track or roadway areas while reducing operator exposure and material waste.

A base part and coupling part simplify seal assembly while maintaining tightness under vibration, wear, corrosion, and varying gap widths.

Microprocessor-controlled pumps and nozzles mix and spray two-component adhesive uniformly onto rail ballast for faster, more stable track bonding.

Direct hydraulic switching raises tamping tool vibration amplitude and frequency while keeping the unit compact enough for simultaneous sleeper tamping.

A guide chamfer ahead of angled guide rings prevents chip entrapment, preserves smooth cutting edges, and lowers drilling friction.

Separate piston surfaces and a pressure accumulator improve vibration control, energy use, and ballast compaction in track tamping.

A pultruded fiber-reinforced polymer shell with lightweight or concrete fill improves rail tie durability, weather resistance, and mass-production consistency.

A spring-mass vibration piston in a track tamper squeezing cylinder cuts hydraulic energy use and noise while maintaining oscillation amplitude.

Segmented guide rings, a helix-parallel guide bevel, and coolant grooves improve drill guidance while preventing chip entrapment and friction.

A sealed oil-bath eccentric drive improves tamping unit durability while external transmission elements let feed drives be replaced quickly.
