II. Product Details (PRODUCT DETAILS)

1. Graded Thrust Design, Suitable for Both Light and Heavy Repairs

• YD14-001 (4T): First Choice for Light Repairs of Family Cars
  The 4-ton thrust is perfectly suitable for light damages of family cars (e.g., Toyota Corolla, Volkswagen Lavida), such as autobody door dents (depth ≤5cm) and bent bumper bracket straightening. The 120mm ram lifting height covers most shallow autobody repairs without disassembling original vehicle parts; the 18kg lightweight design (equivalent to one 10kg bag of rice + one 8kg bag of flour) allows one person to carry it from the tool room to the repair station, or even place it in the trunk of a car for "on-site repair". Compared with traditional manual hammering, repairing a slightly dented door takes only 40 minutes (vs. 2 hours for traditional methods) without hammer marks on metal parts.
• YD14-002 (10T): Core Tool for Heavy-Damage Repairs
  The 10-ton high thrust targets heavy damages of SUVs (e.g., Haval H6, Changan CS75) and light trucks, such as slight bending of frame longitudinal beams (deformation ≤8mm) and dents on autobody A-pillars (steel plate thickness ≤1.5mm). The 2-speed ram height (130mm/150mm) flexibly adapts to deformations of different depths: 130mm gear for shallow dents (avoids reduced stability due to overlong rams); 150mm gear for deep deformations (no need for additional heightening of equipment). Equipped with a pressure regulating valve, the thrust error can be controlled within ±0.5 tons—for example, precise force application during frame repair prevents metal fatigue caused by over-straightening.

2. Hydraulic Power Drive, Both Labor-Saving and Efficient

• Labor-Saving Operation, Reduces Repair Intensity
  With a manual hydraulic pump design, the operating force of YD14-001 is ≤40N (equivalent to lifting a 4kg object), allowing adult women to operate continuously for 1 hour without obvious fatigue; although YD14-002 has higher thrust, its operating force is still controlled within 50N—60% more labor-saving than repeated manual hammering (single force ≥100N), reducing waist and arm strain of repair personnel.
• Efficient Repair, Shortens Vehicle Delivery Time
  Stable hydraulic power output enables the ram to push metal parts back to their original position at a constant speed, avoiding "repeated adjustments" in manual hammering. For example, when repairing an autobody door dent, the hydraulic ram can push the dent flat in one go without repeated supplementary hammering; when straightening a frame longitudinal beam, 10-ton thrust achieves uniform correction in 15 minutes (vs. 1 hour for traditional methods). This helps auto repair shops improve "quick vehicle delivery" capability, especially meeting the demand during peak accident vehicle repair periods.

3. Thoughtful Detail Design, Suitable for All Scenarios

• Portability Adapts to Multiple Scenarios
  YD14-001 (18kg) can be carried by one person for on-site repairs (e.g., repairing slight dents of cars in residential areas without requiring customers to drive to the repair shop); YD14-002 (33kg) is equipped with reinforced handles and can be carried by two people to work under truck chassis. Compared with heavy fixed hydraulic equipment (mostly over 50kg), its mobility is increased by 100%.
• Durability Ensures Long-Term Use
  The inner wall of the hydraulic cylinder is chrome-plated or honed to reduce hydraulic oil friction—both YD14-001 and YD14-002 can achieve "no leakage after 500 repair operations"; the ram is made of high-strength material, with a bending amount ≤0.5mm even under long-term rated thrust. Its service life is 3 times longer than ordinary carbon steel rams (prone to deformation), reducing later accessory replacement costs.

III. Application Scenarios (APPLICATION SCENARIOS)

1. Light Dent Repair of Family Cars in Community Auto Repair Shops (YD14-001 + Blowed Model Case)

1. Select the blowed model case (lightweight for carrying to the repair station, avoiding extra movement burden from heavy iron cases);
2. Connect the hydraulic pump to the ram, adjust the ram to the minimum height of 278mm, and extend it into the position corresponding to the dent from the gap inside the door;
3. Manually press the hydraulic pump, and use the 120mm ram lifting height to push the dent flat at a constant speed—no hammering or secondary damage during the process;
   Result: Repair time is 40 minutes (1 hour and 20 minutes shorter than traditional manual methods); no traces remain on the door surface, improving customer satisfaction.

2. Slight Frame Deformation Straightening of SUVs in Auto 4S Shops (YD14-002 + Iron Case)

1. Select the iron case (fixed in the 4S shop repair workshop for long-term use, impact-resistant and durable to protect internal accessories);
2. Adjust the ram to the 150mm gear (adapting to the depth of the frame longitudinal beam), align it with the deformed position, and set the thrust to 8 tons (lower than the rated 10 tons for safety margin) via the pressure regulating valve;
3. Slowly press the hydraulic pump, and the ram applies force uniformly for straightening; use a level to monitor flatness in real time, completing straightening in 15 minutes;
   Result: The flatness error of the frame longitudinal beam is 0.2mm, meeting the original factory standard without metal fatigue risk—repair quality is recognized by the customer.

3. On-Site Repair of Light Truck Bumper Brackets (YD14-001 + Blowed Model Case)

1. Place the 18kg YD14-001 (in a blowed model case) into the trunk of a family car and transport it to the customer's parking lot;
2. Adjust the ram to the minimum height of 278mm, extend it from the gap under the bumper, and align it with the bent bracket;
3. Manually press the hydraulic pump, and the 4-ton thrust easily straightens the bracket—no external power supply required, completing repair in 30 minutes;
   Result: Solves the customer's "difficulty in using the vehicle" problem, improves the reputation of on-site services, and avoids additional costs of the truck traveling to and from the repair shop.

4. Autobody A-Pillar Dent Repair in Sheet Metal Workshops (YD14-002 + Iron Case)

1. Select the pointed repair head of YD14-002 (adapting to the narrow space of the A-pillar) and adjust the ram to the 130mm gear;
2. Extend the head from the inside of the A-pillar, control the thrust to 6 tons via the pressure regulating valve (avoiding A-pillar deformation due to excessive thrust);
3. Slowly press the hydraulic pump, and the ram pushes the dent uniformly; use a paint film gauge to monitor paint thickness, avoiding paint cracking caused by over-repair;
   Result: The A-pillar dent is completely restored without paint damage; the strength test meets safety standards, and the customer accepts the repair result with confidence.

IV. Frequently Asked Questions (FAQ)

Q1: Can YD14-001 (4T) repair slight frame deformation of SUVs? Will it damage the equipment?

Q2: With a net weight of 33kg, can one person carry YD14-002 to the repair station? How to carry it labor-savingly?

• Short-distance carrying: Hold the reinforced handles on both sides of the equipment with both hands, keep the waist straight, and avoid one-hand lifting (to prevent waist strain);
• Long-distance carrying (e.g., ≥20 meters from the warehouse to the repair workshop): Place the equipment in the iron case and transport it on a small trolley—this is both labor-saving and avoids accessory damage (the iron case has built-in card slots to fix accessories and prevent shaking during carrying);
• Special scenarios (e.g., working under truck chassis): Two people cooperate to lift and place the equipment—one person supports the base, and the other holds the ram to ensure stable placement and avoid tipping and injury.

Q3: During use, the hydraulic ram gets stuck and cannot expand/contract smoothly. What is the reason and how to solve it?

1. Check hydraulic oil level: Close the hydraulic pump valve—check the oil level via the sight glass for YD14-002, or open the oil tank cover for YD14-001. If the oil level is below the scale line, add 46# anti-wear hydraulic oil to the standard position (do not mix other types of hydraulic oil to avoid damaging seals);
2. Discharge air from the system: Loosen the air release valve of the hydraulic pump, press the pump body repeatedly 10-15 times (until no bubbles emerge from the air release valve), then tighten the valve and test;
3. Check oil pipe status: If the ram is still stuck, check if the hydraulic oil pipe is bent (bending blocks oil flow). Arrange the oil pipe to a smooth state to restore normal expansion and contraction.

Q4: After long-term non-use, oil leakage occurs in the hydraulic system. How to handle it?

1. Drain hydraulic oil: Open the oil drain valve of the oil tank, drain all hydraulic oil from the system, and collect it in a dedicated container (to avoid environmental pollution);
2. Replace seals: Disassemble the seals at the connection between the hydraulic cylinder and the oil pipe (seals for YD14-001/002 are universal and can be purchased from the manufacturer, priced at approximately 5 yuan per piece). Wipe the installation groove with alcohol to remove oil stains, install new seals, and apply a small amount of hydraulic oil for lubrication;
3. Test sealing performance: Refill hydraulic oil, press the hydraulic pump to 80% of the rated thrust (3.2 tons for YD14-001, 8 tons for YD14-002), and keep it for 5 minutes—if no leakage occurs, the repair is completed. If leakage persists, check if the inner wall of the hydraulic cylinder is worn (slight wear can be repaired by chrome plating; severe wear requires contacting the manufacturer to replace the cylinder).
