Fork Lift Jacks (4-7T): Chrome-Plated, 2-Position Pad for Fork Lift Service
| Common Parameters | Specific Description |
|---|---|
| Product Type | Fork lift jacks, covering three rated load specifications (4T/5T/7T). Specially designed for fork lift maintenance and servicing scenarios. |
| Core Common Configurations |
|
| Common Applicable Scenarios | Tire replacement, chassis components maintenance, fork arm height adjustment, and daily maintenance of 4-7T fork lifts |
| Model | Rated Capacity | Min. Height (mm) | Max. Height (mm) | Weight (KG) | Core Adaptable Scenarios |
|---|---|---|---|---|---|
| YD21-014 | 4T | 65 | 406 | 33/35 | Light 4T fork lifts maintenance |
| YD21-015 | 4T/5T* | 65/350 | 406/710 | 42/48 | Standard fork lifts and heavy-duty fork arm adjustment |
| YD21-016 | 7T | 65 | 420 | 48/51 | Large fork lifts heavy-component replacement |
The YD21-014 to YD21-016 Fork Lift Jack Series provides professional solutions for fork lift maintenance with three core advantages:
- Two-Position Design: Switchable lift pad adapts to different fork arm spacings (200mm wide position / 150mm narrow position)
- 65-710mm Height Coverage: 65mm low-clearance access eliminates guard plate removal; 710mm high-height support for in-depth operations
- Fully Chrome-Plated Core: Three-layer chrome plating with surface hardness ≥HRC60 resists scratches, moisture, and dust
- Integrated Welding: Robotic automation welding with flaw detection ensures no leakage under heavy load
- Dual Safety Protection: Overload protection valve and anti-slip base with friction coefficient ≥0.85
- Lightweight Operation: 4T model weighs only 33kg; 7T model 48kg for easy manual handling
Process: One person carries jack (33kg) → 65mm low-clearance access → Lift to 406mm → Complete tire replacement in 40 minutes
Result: 40% efficiency increase compared to traditional tools
Process: Switch to 5T mode → Lift to 710mm → Calibrate fork arm angle → Complete adjustment in 1.5 hours
Result: 50% efficiency increase with no fork arm shaking
Process: Two-person carry → 65mm access → 420mm lift height → 3-hour maintenance with no leakage
Result: 80% safety increase for heavy-duty operations
Answer: Not recommended. Although 4.3T doesn't exceed the 4.4T threshold, it's close to the safety limit and may cause unstable operation and reduced component lifespan.
Solution: 1) Clean impurities 2) Add lithium-based grease 3) Check for buckle deformation
Tips: 1) Correct two-person carrying posture 2) Use flat cart for distances over 5m 3) Utilize small fork lift assistance
Solution: For mild scratches, polish with 800-1000 grit sandpaper and apply anti-rust oil. For deep scratches, contact manufacturer for professional chrome plating repair.
