II. Product Details (PRODUCT DETAILS)

1. 6-Grade Load Capacity for Precise Coverage, No Gap Between Light and Heavy Scenarios

• Light-Duty Basic Models (YD14-008/009: 4-10 Ton)
  YD14-008 (4 Ton) is suitable for light operations of family cars and small agricultural machinery, such as door dent straightening and agricultural machinery gearbox part disassembly. The 360ML hydraulic oil capacity meets short-term operation needs, and the 5.5kg lightweight design (equivalent to the weight of a bag of flour) allows one-person portable operation; YD14-009 (10 Ton) is upgraded to 670ML hydraulic oil capacity, suitable for medium-duty operations of SUVs and light trucks (e.g., slight frame bending straightening). With a weight of 6.5kg, it remains easy to move, and its applicable scenarios are expanded by 30% compared with the 4-ton model.
• Medium-Duty Core Models (YD14-010/011: 15-20 Ton)
  Targeting core operations of heavy trucks and engineering equipment, YD14-010 (15 Ton) can be used for straightening truck frame longitudinal beams (thickness ≤5mm), with 690ML hydraulic oil capacity supporting long-stroke operations; YD14-011 (20 Ton) upgrades materials and seals, with high-pressure resistance up to 40MPa, capable of handling heavy-duty needs such as loader connecting arm disassembly. Although the weight increases slightly to 8kg, it is equipped with reinforced handles and can be carried to the work station by two people. Its durability is 50% higher than that of light-duty models.
• Heavy-Duty Exclusive Models (YD14-012/013: 30-50 Ton)
  Specifically designed for ultra-heavy-duty scenarios, YD14-012 (30 Ton) is suitable for part maintenance of large engineering vehicles (e.g., excavators, road rollers), with 900ML hydraulic oil capacity enabling long-term continuous operations; YD14-013 (50 Ton), as the top model in the series, adopts ultra-high-strength alloy steel and heavy-duty seals, with 1200ML large hydraulic oil capacity + 50MPa high-pressure resistance design. It can support ultra-heavy-duty operations such as large motor housing disassembly and engineering vehicle bucket arm straightening. The 11kg weight is controlled by lightweight alloy, with 30% higher mobility than similar 50-ton tools on the market (mostly over 15kg).

2. Universal Interface + Compact Design, Full Adaptability

• ZG 1/4" Universal Interface, No Additional Adaptation Needed
  The entire series uniformly adopts ZG 1/4" standard internal thread interface, which can be directly connected to most manual/electric hydraulic pumps on the market (e.g., common 35MPa manual hydraulic pumps) without purchasing special oil pipes or adapter joints, reducing procurement costs and operational complexity. For example, an auto repair shop's existing 10-ton hydraulic pump can be connected to both YD14-009 (10 Ton) and YD14-010 (15 Ton) to realize "one pump for multiple tools" reuse.
• Compact Size, No Jamming in Narrow Gaps
  With a unified slender package size of 68×14×14cm, the tool body is more compact during actual operation (only 14cm in width), and can extend into narrow spaces such as truck chassis and equipment gaps (e.g., gap ≤20cm). For example, when repairing the inner deformation of a truck frame, YD14-011 (20 Ton) can easily pass through the chassis gap, avoiding the trouble of traditional bulky tools being "unable to enter or turn".

3. High-Strength Materials + High-Quality Seals, Worry-Free Durability

• Rugged Materials, No Deformation Under Heavy Load
  Rams of high-load models (20-50 Ton) are made of special alloy steel, with a maximum tensile strength of 1200MPa. The ram elongation is ≤0.5mm under 50-ton load, which is 75% more stable than ordinary carbon steel rams (elongation often reaching 2mm); the cylinder is made of thick-walled seamless steel pipe, with a maximum high-pressure resistance of 50MPa, ensuring no expansion or leakage during long-term use and avoiding load attenuation caused by cylinder deformation.
• Leak-Proof Seals, Low Maintenance Cost
  Low-load models use nitrile rubber seals, suitable for conventional operating environments; high-load models are upgraded to fluororubber seals, which are anti-aging and high-pressure resistant, enabling up to 2000 reciprocating operations without leakage. For example, YD14-013 (50 Ton) performs 2 heavy-duty operations daily in an engineering factory and still has no hydraulic oil leakage after 2 years of use, reducing maintenance costs by 80% compared with tools with ordinary seals (which often leak after 6 months).

III. Application Scenarios (APPLICATION SCENARIOS)

1. Light Truck Frame Straightening in Auto Repair Shops (YD14-009)

1. Select YD14-009 (10 Ton) – the 6.5kg weight allows one person to carry it to the truck chassis, and the 14cm narrow width easily extends into the chassis gap;
2. Connect the ZG 1/4" interface hydraulic pipe to a manual hydraulic pump, slowly supply oil to 10-ton load, and the ram pushes the bent part of the frame to reset while monitoring flatness in real time;
3. Complete the straightening in 20 minutes – the frame flatness error is ≤0.3mm, meeting safety standards;
   Result: Compared with traditional hammering, the efficiency is tripled with no secondary damage to the frame, improving customer satisfaction with maintenance.

2. Loader Connecting Arm Disassembly in Engineering Stations (YD14-011)

1. Select YD14-011 (20 Ton) – two people carry the 8kg tool to the operation point and connect it to an electric hydraulic pump (directly compatible with ZG 1/4" interface);
2. Align the ram with the pin, slowly output 20-ton pushing force, and the pin is smoothly pulled out in 10 seconds with no jamming or leakage;
   Result: Avoids pin jamming caused by the traditional "jack + crowbar" method (disassembly success rate increased from 60% to 100%), and shortens the operation time to 15 minutes, reducing workers' labor intensity.

3. Large Tractor Support Maintenance in Agricultural Machinery Stations (YD14-012)

1. Select YD14-012 (30 Ton) – two people push the 9kg tool to the tractor and connect it to a hydraulic pump after adjusting the tool height;

IV. Frequently Asked Questions (FAQ)

Q1: Do all models need to be used with dedicated hydraulic pumps? Can ordinary hydraulic pumps be used universally?

Q2: YD14-013 (50 Ton) only weighs 11kg, why can it withstand 50-ton load? Is it safe?

• Material: The ram is made of ultra-high-strength alloy steel containing chromium and molybdenum, with a tensile strength ≥1200MPa (2.5 times that of ordinary carbon steel). Under 50-ton load, it only produces slight elastic deformation (≤0.5mm) with no fracture risk;
• Structure: The cylinder is a 60# thick-walled seamless steel pipe (20mm wall thickness) with 50MPa high-pressure resistance. Reinforcing ribs are provided at the bottom to disperse force and avoid local stress concentration;
  During use, ensure: The tool support surface is flat (steel plates can be padded to increase contact area), and the actual load does not exceed 90% of the rated value (maximum 45 tons for 50-ton tools) – then safe operation can be achieved.

Q3: The tool suddenly cannot build pressure during operation. What is the reason and how to solve it?

1. Check the interface: Disconnect the hydraulic pipe, check if the ZG 1/4" interface is blocked by debris, wipe it clean with a cotton cloth, reconnect it, and ensure the thread is tightened (raw tape can be wrapped to enhance sealing);
2. Replenish hydraulic oil: Open the tool's oil filling port, check the oil level (must be above the minimum scale line), add 46# anti-wear hydraulic oil to the standard position, vent air, and test again;
3. Troubleshoot seals: If pressure still cannot be built, disassemble the tool end cover and check if the seal is deformed (nitrile rubber/fluororubber). Slight deformation can be lubricated with hydraulic oil; severe deformation requires contacting the manufacturer to replace the seal of the same
