III. Application Scenarios (APPLICATION SCENARIOS)

1. Family Car Tire Replacement in Auto Repair Shops (YD21-019)

1. One person carries the YD21-019 (17kg) to the bottom of the front wheel; the minimum height of 150mm easily extends into the chassis and aligns with the support point.
2. Connect to the workshop air compressor (0.8MPa pressure), open the air valve, and lift to a height of 300mm in 4 seconds (the tire is 10cm off the ground), then close the air valve to fix the position.
3. After removing the old tire and installing the new one, slowly open the pressure relief valve to lower the jack to its original position. The whole process takes 8 minutes, and it can serve multiple vehicles continuously.
   Result: Second-level lifting improves workshop turnover efficiency. Compared with traditional tools (15 minutes per vehicle), the efficiency is increased by 47%, suitable for high-frequency tire replacement scenarios in auto repair shops.

2. Emergency Flat Tire Handling for SUVs in Road Rescue (YD21-020)

1. The rescue personnel takes the YD21-020 (with a portable storage bag) from the trunk, carries it to the bottom of the flat tire wheel by one hand, and extends it into the chassis at a height of 150mm.
2. Connect to the on-board air pump (adjusted to 0.9MPa), open the air valve to lift the vehicle in 4 seconds, and fix the wheel with a wheel chock after the tire is off the ground.
3. After replacing with the spare tire, slowly release the pressure to lower the jack to its original position, fold it for storage and put it back into the trunk. The whole process takes 12 minutes, and the balloon does not harden in the -15℃ environment.
   Result: Lightweight and low-temperature resistance adapt to outdoor rescue. Compared with traditional jacks (requiring two people to cooperate), it saves 50% of labor, ensuring the car owner gets out of trouble quickly.

3. Chassis Cleaning of Family Cars by Individual Car Owners (YD21-019)

1. The car owner takes the YD21-019 from the garage, carries it to the bottom of the vehicle by one hand, and extends it into the chassis support point at a height of 150mm.
2. Connect to a household small air compressor (0.7MPa), lift to a height of 250mm in 4 seconds to leave cleaning space.
3. Rinse the chassis impurities with a high-pressure water gun; after cleaning, slowly release the pressure, fold the jack, and store it in the corner of the balcony. The whole process takes 30 minutes.
   Result: Simple operation adapts to individual users, and lightweight storage saves space. Compared with paid on-site cleaning (50 yuan per time), it saves costs and offers flexible timing.

4. Shallow Chassis Inspection of SUVs in Car 4S Stores (YD21-020)

1. The maintenance personnel pushes the YD21-020 to the bottom of the SUV, extends it into the chassis at a height of 150mm, and aligns with the support point.
2. Connect to the workshop high-pressure air source (1.0MPa), lift to the maximum height of 400mm in 4 seconds, and the wide balloon fits the chassis without paint scratches.
3. The maintenance personnel inspects and tightens the chassis bolts; the jack shows no settlement during the 45-minute process, meeting the professional inspection standards of 4S stores.
   Result: Stable load-bearing and chassis protection are balanced. Compared with traditional tools (prone to paint scratches), the service quality is improved, and customer satisfaction is increased by 30%.

IV. Frequently Asked Questions (FAQ)

Q1: Can the YD21-019/020 (3T load capacity) lift a 1.8T SUV? Will it be overloaded?

Q2: When using an on-board air pump for connection, the balloon lifting speed slows down (exceeding 10 seconds). What is the reason and how to solve it?

1. Check the air pump pressure: Confirm whether the output pressure of the on-board air pump reaches 0.7-1.0MPa (some small on-board pumps are only 0.5MPa). If the pressure is insufficient, replace it with a high-pressure air pump (it is recommended to choose a model ≥0.8MPa);
2. Check the air circuit seal: Apply soapy water to the air pipe interface and air valve connection. If bubbles appear, it indicates air leakage. Reinsert the interface tightly or replace the sealing ring (the manufacturer provides spare sealing rings);
3. Clean the balloon air inlet: If there is no air leakage in the air circuit, check whether the balloon air inlet is blocked by dust and impurities. Blow it clean with compressed air (0.3MPa) or wipe it with a cotton swab before trying again.

Q3: With a net weight of 17kg, can female car owners carry it to the bottom of the car alone? Are there any labor-saving tips?

1. Correct carrying posture: Hold the plastic handles on both sides of the equipment (located above the balloon) with both hands, bend the knees slightly and keep the waist straight, and stand up with the help of leg strength. Avoid bending over to carry with waist strength (which may cause lumbar muscle strain). This posture can reduce physical consumption by 30%;
2. Use ground sliding: If the distance from the trunk to the bottom of the car is ≤3 meters, lay the jack flat on the ground and push it gently to the bottom of the car before lifting, saving 60% of effort compared to carrying it the entire time;
3. Use vehicle support: Lean the jack against the side of the vehicle tire, hold both sides with hands and slowly slide it to the bottom of the car, avoiding excessive arm force when lifting directly from the ground.

Q4: After long-term use, the balloon has slight air leakage (dropping 5mm 10 minutes after lifting). How to handle it?

1. Repair surface scratches: If there are shallow scratches on the balloon surface (not penetrating), apply the "balloon repair glue" provided by the manufacturer to the scratches, let it dry for 24 hours, and test—90% of the sealing performance can be restored;
2. Replace the air valve seal ring: If air leaks at the air valve, disassemble the air valve (with a special wrench), take out the internal seal ring, replace it with a spare seal ring from the manufacturer (priced at 10 yuan/set), and tighten the air valve after reassembly;
3. Handling severe air leakage: If the balloon has a penetrating damage (air leakage speed faster than 5mm per minute), contact the manufacturer to replace the original balloon (priced at 150-200 yuan/piece) to avoid safety risks caused by continued use;
4. Daily maintenance: After each use, wipe the surface of the balloon with a dry cloth to remove dust and oil stains, avoid scratches by sharp objects, and store it away from direct sunlight to extend the
