YD23-004 1Ton Hydraulic Coil Spring Compressor (with Fork Adapter & Grid Guard) Webpage Detail Page (English)

I. Product Specifications (SPECIFICATION)

1. Basic Information & Core Parameters

II. Product Details (PRODUCT DETAILS)

1. Foot-Operated Hydraulic Operation + Hands-Free, Dual Improvement of Efficiency and Convenience

(1) Foot-Operated Drive Saves Effort, Easy for Beginners

1. Fix the spring on the adjustable yoke and confirm the parameters are within the adaptation range;
2. Step on the pedal with one foot, the hydraulic push rod automatically advances for compression, and observe the length through the scale line;
3. Release the pedal when reaching the target length, and open the pressure relief valve for quick reset after completion.
   The operation only requires 25N foot force (equivalent to the pressure of a 2.5kg weight), 50% more labor-saving than manual compressors (needing 50N hand force). Operators show no fatigue after continuously compressing 10 springs, and even beginners with no maintenance experience can master the operation proficiently within 10 minutes.

(2) Hands Assist in Fixing, More Accurate Spring Positioning

2. 360mm Grid Guard + Triple Safety Design, Zero Risk in Operation

(1) Full-Enclosure Guard, Eliminating Splashing Hazards

(2) Triple Safety Protection, Dual Guarantee for Equipment and Personnel

• Overload Protection: The hydraulic safety valve automatically relieves pressure when the compression resistance exceeds 1Ton. For example, if a spring with 18mm coil diameter is mistakenly compressed, the equipment shuts down immediately to avoid cylinder bursting or yoke deformation;
• Anti-Slip Yokes: The yoke surface is treated with diamond anti-slip patterns (friction coefficient ≥0.9), combined with adjustable spacing design, preventing spring sliding and deviation during compression. The anti-slip effect is 80% higher than that of smooth yokes (friction coefficient 0.5);
• CE Compliance: CE certified, the equipment materials contain no toxic or harmful substances, and the hydraulic oil meets environmental standards, eliminating compliance concerns for auto repair shops' export procurement.

3. 2 Sizes of Yokes + Wide Parameter Coverage, Suitable for Multiple Scenarios

(1) Dual-Size Yokes, No Additional Purchase Needed

(2) Wide Parameter Compatibility, Adapting to Springs of All Vehicle Models

III. Application Scenarios (APPLICATION SCENARIOS)

1. Shock Absorber Spring Replacement for High-End Vehicles in Car 4S Stores (YD23-004)

1. Two people carry the equipment (35kg) to the lift, select 100-158mm adaptive yokes, fix the spring, and put on the 360mm guard.
2. Step on the hydraulic pedal, and the 315mm stroke compresses the spring from 400mm to 220mm in 20 seconds. Both hands assist in aligning the shock absorber strut.
3. Remove the old spring, install the new one, and open the pressure relief valve to reset. The whole process takes 40 minutes. No debris splashes due to the guard, meeting the 4S store safety standards.
   Result: Full protection and precise operation are suitable for high-end vehicle maintenance, improving customer trust compared to traditional equipment (without protection), while increasing efficiency by 30%.

2. Batch Car Maintenance in Professional Auto Repair Shops (YD23-004)

1. Fix the equipment at a dedicated workstation, use the built-in yokes (100mm size) to quickly fix the spring, compress it with foot stepping (25 seconds per unit), and prepare new springs with both hands simultaneously.
2. The 360mm guard wraps the spring throughout the process, eliminating concerns about debris splashing. One person can operate the equipment and assist in disassembly/assembly at the same time, saving 1 labor force.
3. 192 springs can be processed in 8 hours a day, 60% more efficient than traditional manual equipment (120 units/day), reducing labor costs by 50%.
   Result: Foot-operated labor saving and batch efficiency are suitable for high-frequency operations in auto repair shops, while triple protection ensures employee safety.

3. Special-Shaped Spring Handling in Shock Absorber Repair Centers (YD23-004)

1. Select 158mm size yokes, adjust the spacing to fit the curved surface of the conical spring to ensure firm fixation, and put on the guard.
2. Drive compression with foot-operated hydraulic power, and the 315mm stroke compresses the spring from 450mm to 250mm in 22 seconds. The anti-slip yokes prevent spring deviation.
3. Disassemble the internal components of the shock absorber and replace the seals. The whole process takes 35 minutes. No equipment modification is needed to adapt to special-shaped springs, saving 200 yuan/unit cost compared to traditional equipment (needing custom yokes).
   Result: Adjustable yokes and wide adaptation cover niche vehicle models, expanding the business scope of the repair center while reducing customization costs.

4. Practical Teaching in Automotive Maintenance Training Schools (YD23-004)

1. Fix the equipment at the teaching workstation, explain the CE certification and triple protection principles, and demonstrate the replacement method of the 2 sizes of yokes.
2. During students' practical operation, foot-operated operation requires no force exertion, and the 360mm guard avoids risks from misoperation. Teachers can guide multiple students at the same time.
3. A single teaching session allows 10 students to take turns operating, doubling the teaching efficiency compared to traditional equipment (needing one-on-one teacher protection), with no safety accident risks.
   Result: Safety protection and easy operation are suitable for teaching scenarios, helping students master spring disassembly and assembly skills quickly while reducing teaching safety pressure.

IV. Frequently Asked Questions (FAQ)

Q1: Can the YD23-004 (10-16mm coil diameter) compress heavy-duty SUV springs with 17mm coil diameter? What problems will occur?

Q2: During use, after installing the grid guard, the spring compression progress is hard to see. How to solve this?

1. Adjust the guard position: The guard is designed to be slightly rotatable (±15°). During installation, align the grid gaps with the compression scale lines, and directly observe the length through the gaps to avoid the grid blocking the view;
2. Use a flashlight for assistance: If the light is dim, illuminate from the side of the guard with a flashlight. The spring compression scale will form a clear shadow, facilitating value reading;
3. Mark reference points in advance: Before compression, mark a reference point on the spring surface with a marker pen (e.g., "compress until the mark aligns with the yoke"), and judge the progress through the mark position without frequently checking the scale, improving operation efficiency.

Q3: With a net weight of 35kg, can two people carry the equipment onto the maintenance lift platform of the auto repair shop? Are there any labor-saving tips?

1. Correct carrying posture: Two people stand on both sides of the equipment respectively, hold the metal handles on both sides of the fuselage (load-bearing design area) with both hands, bend their knees slightly and keep their waists straight, and use leg strength to stand up. Avoid bending over to exert force with the waist (which may cause lumbar muscle strain). This posture can reduce physical consumption by 30%;
2. Use a ramp board: Place a ramp board with a load capacity ≥50kg (1.2 meters long) between the lift and the ground. Two people push the equipment from the front and rear respectively, and slide it onto the platform with the help of ramp rolling to save 60% of physical strength compared to direct lifting;
3. Use the lift hook: If the lift is equipped with a hook, bind the equipment handle with a sling with a load capacity ≥50kg, and lift it onto the platform via the lift, without manual carrying—suitable for operators with limited physical strength.

Q4: After long-term use, the two sizes of yokes are worn and cannot fix the spring firmly. How to handle this?

1. Mild wear (shallow anti-slip patterns): Polish the yoke surface with 800-grit sandpaper, re-engrave shallow patterns (0.5mm depth), and apply industrial anti-slip agent to restore 80% of the anti-slip effect;
2. Moderate wear (local deformation): Gently correct the deformed part of the yoke with a wrench (only applicable to slight bending), and use it with anti-slip rubber pads (2mm thick) after polishing to enhance fixity;
3. Severe wear (yoke cracking or severe deformation): Contact the manufacturer to purchase original yokes (100mm-158mm set priced at 120 yuan). After replacement, it is recommended to check the wear condition every 3 months to avoid spring slippage due to overuse;
4. Daily maintenance: After each use, wipe off oil stains and metal debris on the yoke surface with a dry cloth, avoid rust caused by humid environments, and extend the yoke service life.
