I. Product Specifications (SPECIFICATION)

II. Product Details (PRODUCT DETAILS)

1. 42-54cm Pneumatic Height Adjustment, Adapting to All-Scenario Sitting Postures
   Equipped with a high-quality pneumatic hydraulic rod and a side lever adjustment structure, no power supply is required. The height can be smoothly adjusted by manually pulling the lever, covering two core scenarios:

• Low Height (42-46cm): Suitable for "semi-squat inspection" scenarios, such as brake line inspection of car chassis and disassembly/assembly of small parts of agricultural machinery gearboxes. Mechanics can bend their knees naturally and keep their upper bodies close to the equipment, avoiding waist soreness caused by long-term bending;
• High Height (48-54cm): Suitable for "sitting work" scenarios, such as parts assembly, maintenance recording, and tool organization. Feet can stand firmly on the ground, knees bend naturally at 90°, and there is no leg numbness even after sitting for more than 1 hour.
  The hydraulic rod has passed 12,000 lifting tests and still maintains stable performance without "oil leakage or jamming". It is suitable for mechanics with heights of 1.55-1.9m, and the scenario coverage rate is increased by 70% compared with fixed-height stools.

2. Fully Padded Foam Cushion, Balancing Comfort and Durability
   The stool surface adopts a combined design of "6cm high-density foam + PVC waterproof and oil-resistant fabric":

• Comfort and Fatigue Resistance: The foam density reaches 35kg/m³, balancing support and softness. When sitting, the hip pressure is evenly distributed, and the waist fatigue is reduced by 60% after 2 hours of continuous work. The comfort is 3 times higher than that of ordinary hard stools;
• Oil Resistance and Easy Cleaning: The outer PVC fabric has an IPX4 waterproof rating. Engine oil and gear oil can be wiped clean with a dry cloth without oil penetration. It has passed the friction test (no pilling after 500 rubs), and the fabric will not be damaged after long-term use, adapting to the "oily and dusty" harsh environment of auto repair shops.

3. Built-in Tool Tray, No Loss of Parts and Tools
   A detachable tool tray (size 20×15cm) is integrated on the side of the stool surface, with three advantages:

• Convenient Storage: It can hold small tools and parts such as wrenches, screwdrivers, and screw washers, avoiding tools falling into the car bottom or ground during inspection, reducing the time for "finding tools", and increasing the maintenance efficiency of a single vehicle by 25%;
• Flexible Disassembly: The tray is connected to the stool surface via a buckle, which can be quickly removed when lying down for inspection without affecting operation; it can also be used alone as a parts tray, adapting to the "multi-station parts transfer" scenario;
• Reliable Load Capacity: The tray is made of ABS engineering plastic, with a rated load capacity of 5kg. It will not deform when holding a full set of commonly used tools (about 3kg), and the edge is designed with a 2cm-high flange to prevent small parts from slipping.

4. 4 Swivel Mute Casters, Unobstructed Movement in the Workshop
   Equipped with 4 3-inch high-elastic rubber swivel casters, balancing "muteness" and "smoothness":

• Mute Work: The friction noise between the casters and the ground is ≤48 decibels (equivalent to library ambient volume), which will not interfere with customer rest or the work of adjacent stations even in the indoor maintenance area of 4S stores. Compared with traditional metal casters (noise ≥75 decibels), the noise is reduced by 36%;
• Flexible Movement: It supports 360° omnidirectional rotation, with a minimum turning radius of only 28cm. In areas with dense equipment in the workshop (such as between tool racks and multi-station maintenance areas), it can be adjusted by gently pushing, with a rolling resistance of ≤28N. Compared with stools without casters, the movement efficiency is increased by 500%, reducing the physical consumption of mechanics moving back and forth to pick up items.

III. Application Scenarios (APPLICATION SCENARIOS)

1. Car Chassis Inspection in Auto Repair Shops
   An auto repair shop conducts chassis abnormal noise inspection on a Toyota Corolla (chassis clearance 14cm), and the mechanic uses the YD11-006: Adjust the height to 45cm, approach the chassis in a semi-squat posture, and place a stethoscope and small wrench on the tool tray; flexibly adjust the position via swivel casters during inspection without frequent standing up; after finding the abnormal noise point, adjust to a height of 50cm to record data. The inspection time for a single vehicle is shortened from 80 minutes to 55 minutes, adapting to the "seamless connection between inspection and recording" scenario.
2. Vehicle Maintenance Workstation in 4S Stores
   A 4S store conducts regular maintenance on a Mercedes-Benz E-Class, and the mechanic uses the YD11-006: Adjust to a height of 48cm, sit by the workstation to replace the oil filter, and store the filter element and sealing ring in the tool tray; there is no need to stand up during maintenance intervals, and maintenance documents can be organized directly on the stool. The oil-resistant fabric prevents oil stains on the body from contaminating the stool; customers can also use the stool temporarily when checking the maintenance progress, improving the brand service experience, adapting to the "4S store professional maintenance + customer experience" scenario.
3. Precision Component Assembly in Agricultural Machinery Repair Stations
   An agricultural machinery repair station assembles hydraulic joints for a Dongfanghong tractor, and the mechanic uses the YD11-006: Adjust to a height of 46cm, place joints, sealant, and wrenches on the tool tray; approach the workbench via swivel casters during assembly without frequent bending to pick up parts; after engine oil splatters on the stool surface, it can be cleaned by wiping with a cloth without residual stains, adapting to the "precision agricultural machinery assembly + oil stain protection" scenario.
4. Parts Maintenance of Small Construction Machinery
   An engineering team repairs the fuel injector of a small generator (chassis clearance 16cm), and the mechanic uses the YD11-006: Adjust to a height of 44cm, disassemble the injector in a semi-squat posture, and place disassembly tools and small parts on the tool tray; after maintenance, remove the tray to transfer parts to the cleaning area, and push the stool to the corner for storage without occupying inspection space, adapting to the "construction machinery maintenance + space saving" scenario.

IV. Frequently Asked Questions (FAQ)

Q1: The tool tray can bear 5kg of tools. Will placing a 6kg heavy wrench damage the tray?

Q2: With a net weight of 5.7kg, can female mechanics carry it alone from the warehouse to the maintenance workstation (30 meters away)?

Q3: The pneumatic hydraulic rod becomes slow in lifting after 1 year of use. How to handle it?

Q4: When used on uneven concrete ground (protrusions ≤4mm), will the casters be stuck?
