III. Application Scenarios (APPLICATION SCENARIOS)

1. Chassis Overhaul of Light Trucks in Auto Repair Shops (YD19-004)

1. One person pushes the jack to the bottom of the truck; the 125mm minimum height easily extends under the chassis and aligns with the beam support point.
2. Press the handle to lift; the roller-cam plunger design reduces operating intensity, lifting to 400mm height.
3. Maintenance personnel disassemble components; no shaking during the 2-hour process, and the vehicle is slowly lowered after completion by releasing pressure.
   Result: 50% more efficient than ordinary jacks; no operator fatigue after maintaining 5 vehicles a day, adapting to high-frequency operations.

2. Tire Replacement of Heavy SUVs in Logistics Parks (YD19-004)

1. Push the jack to the bottom of the SUV's rear wheel; the 125mm height is compatible with the chassis without heightening.
2. 30 pumps lift the tire 8cm off the ground; the overload protection monitors the load (2.3Ton ＜ 3.3Ton).
3. Complete tire replacement in 10 minutes; push the jack to the next vehicle for continuous operation.
   Result: Convenient roller movement and labor-saving design shorten time; 15 vehicles can be serviced a day, meeting the fast turnover needs of logistics parks.

3. Installation of Small Equipment by Engineering Teams (YD19-004)

1. Push the jack to the bottom of the generator; the 125mm height extends into the equipment base.
2. Lift to 350mm height; the double-sealed hydraulic system prevents dust intrusion.
3. No jamming or displacement during the 1-hour installation, ensuring equipment stability.
   Result: Dust-resistant design adapts to outdoor environments; zero failures compared to ordinary jacks, improving installation safety.

4. Outdoor Vehicle Maintenance in Northern Winter (YD19-004)

1. Push the jack to the bottom of the truck; the 125mm height extends under the chassis.
2. The hydraulic system works normally at low temperature; the labor-saving structure easily lifts to 300mm.
3. No jamming during the 40-minute maintenance; the vehicle is slowly lowered after completion.
   Result: Strong low-temperature adaptability avoids maintenance delays caused by tool jamming, improving winter operation efficiency.

IV. Frequently Asked Questions (FAQ)

Q1: Can YD19-004 (3Ton) lift a 3.2Ton medium truck? Will the overload protection be triggered?

Q2: The rollers are stuck and cannot be pushed flexibly. What is the reason and how to solve it?

1. Clean impurities: Use a screwdriver to remove stones, wires, etc. from the roller gaps, then test pushing;
2. Rust removal and lubrication: Disassemble the roller shaft, polish rust with sandpaper, apply lithium-based grease, and reassemble;
3. Replace worn parts: If the roller surface is uneven, replace it with a roller of the same specification (40-60 yuan/piece);
   It is recommended to clean and lubricate the rollers monthly to ensure flexible movement.

Q3: With a shipping weight of 45.5kg, can one person unload and carry it to the workshop?

1. Unloading: Use a forklift to place the package on the ground, or pad 3 logs to push the package to the workshop (reducing sliding friction);
2. Unpacking: Unpack directly in the workshop, use the jack's rollers to push it to the operation point without lifting;
3. Short-distance carrying: Hold the hidden handles on the chassis, lift with knee strength instead of waist strength to reduce strain.

Q4: After long-term non-use, the hydraulic pressure relief is slow. What is the reason and how to solve it?

1. Clean the pressure relief valve: Disassemble the valve core, rinse impurities with alcohol, and reassemble after drying;
2. Activate seals: Press the handle repeatedly 5-10 times (without lifting) to relieve seal sticking;
3. Replace hydraulic oil: If idle for more than 1 year, drain old oil and add 46# anti-wear hydraulic oil to the scale line;
   It is recommended to lift and lower the jack once every 3 months to prevent oil aging and seal sticking.
