Professional hydraulic pull back rams designed for multi-scenario applications in automotive, agriculture, and engineering industries.

• YD14-004 (2T): Lightweight (18kg) with 120mm stroke for family cars and small equipment
• YD14-005 (5T): 5-ton force for SUVs/light trucks with reinforced handles
• YD14-006 (10T): Upgraded materials for heavy trucks/engineering equipment
• YD14-007 (20T): Special alloy construction for ultra-heavy-duty applications

• Rams with tensile strength up to 1100MPa (YD14-007)
• Honed cylinder inner walls (surface roughness ≤0.8μm)
• NBR seals for 2T/5T models, FKM seals for 10T/20T models
• No leakage after 1000+ operations (10T/20T models)

• Compact sizes for narrow spaces (e.g., 575mm length for YD14-004)
• Detachable connectors for multiple operation types
• Lightweight construction for easy mobility

Repairing inner door dents (4cm depth) on Honda Civic without paint damage. Operation time reduced by 50% compared to traditional methods.

Disassembling stuck gear shafts in tractor gearboxes. Prevents shaft deformation with 100% reuse rate.

Straightening loader bucket connecting arms (8mm thickness). On-site repair saves transportation costs.

Removing cast iron motor housings (100kg weight). Eliminates housing damage common with traditional methods.

A1: No - ordinary single-acting hydraulic pumps (30-40MPa) can be used universally.

A2: Special alloy material and optimized structure provide both lightweight and high strength. Safety ensured when used within 90% of rated capacity.

A3: Check hydraulic oil level, seals, and return spring. Add oil if low, inspect seals for damage, and verify spring function.
