A powerful self‑propelled heavy‑duty trailer, the PST/SL‑6 combines robust traction and mechanical steering, enabling high precision positioning without a prime mover. With 200 kN pulling force per driven axle line, steep inclines are handled with fewer axles. The modular design supports 4–8 axle configurations and integrates seamlessly with towed modules or other PST/SL units. User‑friendly controls, reliable pendular axles, and compact width make it ideal for on‑site heavy moves and flexible fleet use.

Key Features:

• 200 kN traction per driven axle line delivers exceptional pulling power
• Mechanical pendular axle steering (±55°) ensures precise maneuvering
• Modular axle-count (4–8) scales with load demands
• 3 m width optimized for site navigation and rack shipping
• Compatible with PST PowerPacks (e.g. Deutz, Cummins up to 530 PS) and tow‑mode SPEEDRIVE

Safety Features:

• Twin‑tire pendular axles offer stability across terrain variations
• Mechanically robust pendular axle bearings reduce rollover risk
• Mechanical steering ensures fail‑safe control even without electronics
• Disengageable drive axles prevent wear and overheating during tow
• Radio/cable emergency remotes ensure immediate stop capability

Transport Specifications:

• Self‑propelled: no prime mover needed for millimeter‑accurate load placement
• Towed SPEEDRIVE mode supports road travel up to 80 km/h under regulations
• Compact width (3 m) enables flat rack or trailer transport without wide‑load permits
• Modular axle setup reduces total trailer count per move, improving efficiency
• Pendular axles with 600 mm compensation ensure smooth loading/unloading
