II. Product Details (PRODUCT DETAILS)

1. 4,500 LBS Strong Load-Bearing + Dual-Cylinder Drive, Stable Performance

(1) High-Strength Structure, Rugged and Impact-Resistant

• The bracket body is welded with Q235B carbon steel (key parts thickened to 12mm), with a tensile strength of ≥375MPa. When carrying a 4,500 LBS vehicle, the bracket bending is ≤0.3mm, far exceeding the shortcoming of "ordinary rotisseries deforming at 3,000 LBS";
• Connection parts are fastened with Grade 8.8 high-strength bolts (torque value 50-55N·m), with no false welds, no loosening risk during long-term use, and suitable for high-frequency maintenance operations.

(2) Synchronous Dual-Cylinder Lifting, Safe and Reliable

• The dual hydraulic cylinders are independently controlled but have a synchronization error of ≤0.5mm. The vehicle body remains horizontal during lifting, avoiding part slipping due to one-sided inclination;
• Built-in overload protection device: When the load exceeds 4,500 LBS, the hydraulic system automatically relieves pressure to prevent damage to the hydraulic cylinders and brackets, and simultaneously issues an audible and visual alarm to remind operators.

2. 360° Rotation + Flexible Movement, High Maintenance Efficiency

(1) All-Angle Operation, No Maintenance Blind Spots

• 360° free-rotation bearing: The vehicle body can be easily rotated manually. Whether it is chassis welding, body rust removal, or paint spraying, the maintenance part can be adjusted to the optimal operation angle (e.g., turning the chassis upward without bending or kneeling), increasing operation efficiency by 60%;
• Adjustable-length bracket: By telescoping the bracket rod, it is compatible with vehicles with wheelbases of 121.7-260 inches, eliminating the need for custom brackets for different vehicles and reducing maintenance costs.

(2) Caster Movement + Locking, Strong Scene Adaptability

• 8-inch polyurethane casters: High load-bearing capacity, rolling without scratches on concrete floors or tile floors in repair shops. When pushing the rotisserie with a loaded vehicle, the force required by a single person is ≤80N, making it easy to adjust the operation position;
• Caster locking function: After pressing the locking pedal, the brake pads closely fit the rim, with an anti-slip coefficient of ≥0.8. Even on a 5° inclined ground, the rotisserie has no displacement, ensuring maintenance safety.

3. Durable Coating + Humanized Design, Excellent User Experience

(1) Corrosion and Scratch Resistance, Low Maintenance Cost

• Surface powder coating: Cured at high temperature (180℃ for 20 minutes), with strong adhesion. No scratches from tool collisions or part friction, and no rust for 3 years of use in humid repair shop environments;
• Bearing waterproof design: The rotating bearing has built-in double-lip sealing rings to prevent dust and water from entering, eliminating the need for frequent grease addition and extending the maintenance cycle to once every 6 months.

(2) Detail Optimization, Low Operation Threshold

• Lifting height marking: Clear scales (accuracy 1cm) are printed on the side of the bracket, facilitating precise control of the lifting height and avoiding collision between the vehicle body and the ceiling;
• Lightweight design: Although the rated load is 4,500 LBS, the rotisserie itself weighs only 238 kg. With casters, 2 people can adjust the position without relying on large equipment;
• Accessory compatibility: The optional Rotisserie Leg Kit can be purchased to provide additional support when rotating the vehicle body, especially suitable for scenarios requiring stable operations such as body welding, increasing safety by 50%.

IV. Frequently Asked Questions (FAQ)

Q1: During use, the dual hydraulic cylinders lift asynchronously, with one side of the vehicle body higher than the other. What is the reason?

1. Check Hydraulic Oil Level: Turn off the hydraulic system, open the oil tank cap. If the oil level difference between the oil circuits connected to the two hydraulic cylinders is ＞1cm, add 46# anti-wear hydraulic oil to make the oil levels on both sides consistent, ensuring uniform oil supply;
2. Discharge Air from Hydraulic Cylinders: Lower the vehicle body to the lowest position, loosen the exhaust valve on the top of the hydraulic cylinder, and slowly lift the vehicle body to the highest position. At this time, air will be discharged from the exhaust valve (bubbles will appear). Close the exhaust valve after no more bubbles are released, and re-test the lifting synchronization;
3. Check Hydraulic Valve: If the above operations are ineffective, the hydraulic control valve may be stuck. Disassemble the valve body and clean it (flush the valve core with diesel to remove impurities), apply hydraulic oil for lubrication after re-installation, and ensure the valve core moves flexibly.

Q2: During vehicle body rotation, the resistance is too large and even rotation is impossible. How to handle it?

1. Add Grease: Turn off the rotisserie, disassemble the rotating bearing end cover with a wrench, apply lithium-based grease (thickness 2-3mm) between the bearing balls and raceways, and manually rotate the bearing after application to ensure uniform lubrication. The resistance will be significantly reduced;
2. Clean Impurities: If there are metal chips or dust in the bearing, blow off the impurities with compressed air, then apply grease to avoid bearing raceway wear caused by impurities (it is recommended to clean once every 3 months, and monthly in humid environments);
3. Check Vehicle Body Fixing: Excessively tight body fixing clamps will increase rotation resistance. Loosen the clamp bolts and adjust the clamping force (to the extent that the vehicle body has no wobble) to avoid excessive clamping causing rotation difficulties.

Q3: How to judge whether a vehicle is compatible with the YD42-002 Automotive Rotisserie?

1. Confirm Vehicle Weight: The vehicle's curb weight must be ≤2,025 kg (4,500 LBS). If it exceeds this weight (e.g., a medium-sized SUV with a curb weight of 2.2 tons), the rotisserie will be overloaded, and a model with higher load capacity is required;
2. Confirm Vehicle Wheelbase: The vehicle's wheelbase must be within the range of 121.7-260 inches (approx. 309-660 cm). If the wheelbase is too short (e.g., a micro-car with a wheelbase of 2.3m) or too long (e.g., a mid-to-large sedan with a wheelbase of 3.1m), a bracket adapter of corresponding length needs to be replaced (customization service is available from the merchant);
3. Confirm Body Structure: It is compatible with non-load-bearing bodies (with independent chassis) and load-bearing bodies (special chassis brackets need to be installed). For bodies with special structures (e.g., convertibles without a complete roof beam), additional auxiliary supports need to be installed to avoid body deformation during rotation.

Q4: After long-term use, the casters become stuck and cannot roll smoothly. How to solve this problem?

1. Clean Wheel Axle Impurities: Pry open the caster dust cover with a screwdriver, blow off the dust and debris in the wheel axle with compressed air. If there are tangled threads or hair, cut them off with scissors and clean to avoid hindering rolling;
2. Lubricate Bearings: Drop 3-5 drops of lubricating oil (e.g., sewing machine oil, light machine oil) into the caster bearings, manually rotate the casters 10-20 times to ensure the lubricating oil penetrates into the bearings, and the stuck feeling will be eliminated;
3. Replace Damaged Parts: If the caster tires are severely worn (tread depth ＜1mm) or the bearings are damaged (abnormal noise during rotation), replace them with casters of the same specification (8-inch polyurethane material, load capacity ≥1,000 LBS/piece). After replacement, test the rolling smoothness to ensure compatibility with the rotisserie.
