Heavy-duty roller-cam plunger hydraulic jack with double-sealed system, designed for trucks, SUVs, and engineering equipment. Rated capacity: 6,666LBS (3,000KGS/3Ton) with overload protection.

• Heavy Gauge Steel Construction: 12mm cold-rolled steel with tensile strength ≥1000MPa
• Roller-Cam Plunger Assembly: Reduces operating force by 40% with chrome-plated plunger
• Double-Sealed Hydraulic System: Works normally at -20℃ with dust/water protection
• Flanged Side Plates: 30% increased bending strength
• Built-in Overload Protection: Automatic oil cut-off when load exceeds 3.3Ton

Main body made of 12mm thick cold-rolled steel with no permanent deformation after 100,000 fatigue tests. Front-narrow-rear-wide chassis layout provides 15% larger grounding area than symmetric chassis jacks.

Rolling friction reduces operating force to ≤55N. Chrome-plated plunger extends service life by 2* with wear ≤0.02mm after 500 consecutive lifts.

Nitrile rubber main seal + PTFE auxiliary seal prevent oil leakage. Low-temperature hydraulic oil maintains fluidity at -20℃.

1. Push jack to truck bottom (125mm min height)
2. Lift to 400mm height with roller-cam plunger
3. Complete maintenance with stable lifting

Result: 50% more efficient than ordinary jacks with no operator fatigue.

1. Position jack under SUV's rear wheel
2. 30 pumps lift tire 8cm off ground
3. Complete tire replacement in 10 minutes

Result: 15 vehicles can be serviced daily with convenient roller movement.
