I. Product Specifications (SPECIFICATION)

II. Product Details (PRODUCT DETAILS)

1. 450 LBS Ultra-High Load Capacity + 5 Sets of Metal Wing-Shaped Brackets, No Collapse in Heavy-Duty Work

• Strong Support Against Deformation: 5 sets of laser-cut metal wing-shaped brackets are distributed in a "radial" pattern, forming a triangular stable structure with the seat surface and foot ring, with an overall load capacity of up to 450 LBS (204kg); even when carrying a 180kg worker + 24kg heavy tools (such as heavy socket wrenches), the brackets show no bending and the welding points show no cracking. Compared with ordinary workshop seats (mostly 150kg load capacity), the stability is improved by 36%.
• Anti-Rust and Durable: Both the brackets and foot ring undergo electrostatic spray-painting treatment, with no rust in 200-hour salt spray tests. In dusty and humid environments of heavy machinery factories, the service life can reach 10-12 years, which is 2.5 times the durability of ordinary painted brackets.

2. 470-590mm Pneumatic Height Adjustment, Suitable for All Heights
   Equipped with a high-quality pneumatic hydraulic rod and a side lever adjustment structure, it has two advantages:

• Wide Adjustment Range for Strong Adaptability: The minimum height of 470mm is suitable for "semi-squat maintenance" (such as disassembly and assembly of heavy truck chassis components), and the maximum height of 590mm is suitable for "sitting work" (such as equipment control panel debugging and maintenance recording), covering the needs of workers with heights of 1.55-1.95m. Compared with fixed-height seats, the scenario adaptability rate is increased by 90%.
• Smooth Adjustment Without Jamming: The lever control force is ≤15N, allowing smooth height switching with one hand. The hydraulic rod has a uniform lifting speed (5mm/s) without "sudden lifting or dropping". It still maintains stable performance after 15,000 cycle tests, avoiding frequent maintenance and replacement.

3. 580mm Circular Foot Ring + Casters with Brakes, Balancing Stability and Flexibility

• Circular Foot Ring Prevents Tipping: The 580mm-diameter circular rail structure increases the bottom support area (ground contact area up to 0.27㎡). Even on sloped ground (slope ≤3°) or when workers lean sideways to pick up tools, the seat has no tipping risk. Compared with seats without foot rings, the stability is improved by 60%.
• Casters with Brakes Control Displacement: The 4" rubber swivel casters support 360° rotation for flexible movement and are equipped with independent brake devices—after pressing the brake lever, the caster locking force is ≥80N, keeping the seat fixed. It is suitable for scenarios where "stable support is needed during maintenance and flexible switching is needed during movement", avoiding safety hazards caused by seat sliding during work.

4. 100mm-Thick PVC Foam Seat Surface, Balancing Comfort and Stain Resistance

• Fatigue Resistance During Long Sitting: The 100mm-thick high-density foam (density 42kg/m³) can evenly distribute the pressure on the hips and waist. After 3 hours of continuous work, the waist fatigue is reduced by 80%, and the comfort is twice that of seats with 50mm-thick cushions.
• Oil Resistance and Easy Cleaning: The outer PVC fabric has an IPX4 waterproof rating. When engine oil, gear oil, or coolant splatters, it can be wiped clean with a dry cloth without oil penetration. The fabric is resistant to high and low temperatures (-30℃~100℃), suitable for special environments such as high-temperature metallurgical workshops and low-temperature cold chain warehouses, with no need for additional protection.

III. Application Scenarios (APPLICATION SCENARIOS)

1. Equipment Maintenance Workstation in Heavy Machinery Factories
   A heavy machinery factory performs spindle maintenance on a 50-ton CNC machine tool, and workers use the YD11-013: Adjust the seat height to 520mm, and the 450 LBS load capacity supports workers carrying 20kg maintenance tools (such as hydraulic pullers) for work; the circular foot ring ensures no tipping when operating sideways next to the machine tool, and the seat is stably fixed after the caster brakes are locked; the 100mm-thick seat surface relieves fatigue from long-term bending, shortening the maintenance time of a single machine tool from 180 minutes to 140 minutes, adapting to the "heavy-duty equipment maintenance" scenario.
2. Heavy Truck Maintenance Area in Auto Repair Shops
   An auto repair shop performs transmission maintenance on a Dongfeng Tianlong heavy truck (chassis height 800mm), and the mechanic uses the YD11-013: Adjust to a height of 490mm for semi-squat work, and 5 sets of metal brackets support the weight of the body + tools; during maintenance, release the brakes to push the seat to different maintenance points without frequent standing up; after the PVC seat surface is stained with diesel, it can be cleaned by wiping, adapting to the "heavy truck chassis maintenance" scenario.
3. Construction Machinery Maintenance Point
   An engineering team repairs the hydraulic pump of a 20-ton excavator, and workers use the YD11-013: Adjust to a height of 550mm to sit and inspect the hydraulic pipeline; the circular foot ring maintains stability on the uneven ground of the construction site; sitting on the seat with 15kg hydraulic testing tools, the brackets show no deformation; after work, push the seat to the tool storage area and lock it with brakes to avoid sliding, adapting to the "outdoor construction machinery maintenance" scenario.
4. Heavy-Duty Shelf Organizing Workstation in Logistics Warehouses
   Workers organize 3-meter-high heavy-duty shelves (storing 50kg/unit parts boxes) in a logistics warehouse, using the YD11-013: Adjust to the maximum height of 590mm to stand and assist in picking and placing parts on the middle layer of the shelves; the foot ring provides stable support to avoid tipping when standing on tiptoes; release the brakes when moving to easily shuttle between shelves, adapting to the "high-load warehouse work assistance" scenario.

IV. Frequently Asked Questions (FAQ)

Q1: Can the 450 LBS load capacity support a long-term weight of 200kg (e.g., 180kg worker + 20kg tools)? Will it affect the service life?

Q2: With a net weight of 15kg, can female workers push it alone from the warehouse to the maintenance workstation 35 meters away?

Q3: The pneumatic hydraulic rod becomes slow in lifting after 3 years of use. How to handle it?

Q4: When used in a high-temperature metallurgical workshop (ground temperature 60℃), will the rubber casters melt?
