The YD11-014 Durable Workshop Seat with Backrest is a high-strength equipment designed to address the pain points of "lack of waist support leading to fatigue during long-term work in heavy-duty workshops, insufficient load capacity and easy deformation of seats, and uncomfortable sitting postures due to height differences". With "450 LBS ultra-high load capacity + 5 sets of metal wing-shaped brackets + angle-adjustable backrest" as the core, combined with a circular foot ring and pneumatic height adjustment, it realizes the triple needs of "heavy-duty stability + waist care + flexible adaptation", providing a "safe, comfortable and durable" sitting solution for heavy industrial scenarios. Its core advantages are as follows:
- 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.
- Angle-Adjustable Backrest (90°-110°), More Comfortable Waist Support
The seat is equipped with a humanized angle-adjustable backrest, solving the problem of "waist soreness during long sitting" of traditional backless seats:
- Fits Curve to Protect Waist: The backrest is 457mm high and 305mm wide, with an adjustable angle between 90° (upright work) and 110° (relaxed rest), which can accurately fit the waist curve and disperse waist pressure; after 3 hours of continuous work, waist fatigue is reduced by 85%, and the comfort is twice that of backless seats.
- Waterproof, Stain-Resistant and Easy to Clean: The backrest fabric is the same as the seat surface, made of PVC waterproof and oil-resistant material. When engine oil or gear oil splatters, it can be wiped clean with a dry cloth without oil penetration; the backrest bracket is detachable, which can be folded during transportation or storage, saving 50% of storage space.
- 470-590mm Pneumatic Height Adjustment + Circular Foot Ring, Balancing Adaptability and Stability
- Wide Adjustment Range for All Heights: 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%.
- 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%.
- 4" Casters with Brakes + PVC Foam Seat Surface, Balancing Safety and Comfort
- 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 and avoiding safety hazards caused by seat sliding during work.
- Fatigue Resistance During Long Sitting: The 100mm-thick high-density foam (density 42kg/m³) can evenly distribute hip pressure; combined with backrest support, there is no obvious fatigue even after 4 hours of continuous work; the PVC 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.

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 YD11-014: Adjust the seat height to 520mm and the backrest angle to 100°; 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 backrest 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.

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 YD11-014: Adjust to a height of 490mm for semi-squat work, and set the backrest angle to 95° to fit the waist; during maintenance, release the brakes to push the seat to different maintenance points without frequent standing up; after the PVC fabric is stained with diesel, it can be cleaned by wiping, adapting to the "heavy truck chassis maintenance" scenario.

Construction Machinery Maintenance Point
An engineering team repairs the hydraulic pump of a 20-ton excavator, and workers use the YD11-014: Adjust to a height of 550mm to sit and inspect the hydraulic pipeline, and set the backrest angle to 105° to relax the waist; 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.

Long-Duration Rest Area in Workshops
Workers in heavy-duty workshops use the YD11-014 during lunch breaks: Adjust to the maximum height of 590mm and set the backrest angle to 110°; combined with the 100mm-thick seat surface, it provides a comfortable resting posture; the foot ring and casters ensure stability without sliding during rest; the PVC fabric is oil-resistant and can be restored to cleanliness by wiping after the break, adapting to the "long-duration workshop rest" scenario.
A1: Short-term use is allowed, but long-term use is not recommended—safety margin should be reserved. 200kg does not exceed the 204kg rated load capacity, but long-term full-load use will cause fatigue of metal brackets and loosening of backrest connecting bolts, and may even lead to backrest tilting; in daily use, it is recommended to control the total weight within 180kg (e.g., 160kg worker + 20kg tools), and check the tightness of backrest bolts once a month to avoid continuous heavy loads affecting backrest stability.
A2: Yes, it can be easily pushed, and the caster design reduces handling difficulty. The seat is equipped with 4" low-resistance swivel casters (rolling resistance ≤30N), so female workers only need to exert slight force to push it, and the 35-meter distance takes about 1.5 minutes; the casters have shock absorption, so there is no jamming even if there are slight gravels (diameter ≤5mm) on the ground; if encountering small steps (height ≤5cm), tilt the seat to let the front wheels go up first, then push the rear wheels, no need to fully lift it, adapting to the "single-person low-frequency handling" scenario.
A3: It is mostly due to dust accumulation on the dust cover or hydraulic oil loss, which can be checked in the following steps: ① Adjust the seat to the maximum height, remove the dust cover on the top of the hydraulic rod, and clean the dust and debris with a brush to prevent impurities from entering the interior; ② If it is still slow after cleaning, drop 3-5 drops of special hydraulic oil (available from the manufacturer, approx. 20 yuan/bottle) and lift/lower repeatedly 5 times for running-in; ③ If there is still no improvement, contact the manufacturer to replace the original hydraulic rod (priced at 120 yuan/piece). Only the bottom fixing screws need to be removed for replacement, no professional tools required.
A4: Increasing the angle is not recommended, as there is a safety risk. The connection structure between the backrest bracket and the main frame is only suitable for the angle range of 90°-110°. Forcibly increasing the angle to 120° will cause deformation of the backrest bracket, breakage of connecting bolts, and may even lead to seat tipping; if lying down to rest is needed, it is recommended to choose a dedicated recliner to avoid affecting the seat's service life and safety due to excessive angle.
