Product Details
The YD21-014 to YD21-016 Fork Lift Jack Series provides professional solutions for fork lift maintenance with three core advantages:
Two-Position Lift Pad + Wide Height Range
- 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
Chrome-Plated Components + Welded Structure
- 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
Multi-Standard Compliance + Lightweight Design
- 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
Application Scenarios
Tire Replacement of 4T Fork Lifts in Logistics Parks (YD21-014)
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
Fork Arm Adjustment of 5T Fork Lifts (YD21-015)
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
Chassis Maintenance of 7T Fork Lifts (YD21-016)
Process: Two-person carry → 65mm access → 420mm lift height → 3-hour maintenance with no leakage
Result: 80% safety increase for heavy-duty operations
Frequently Asked Questions
Q1: Can the YD21-014 (4T) lift a 4.3T fork lift?
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.
Q2: What if the lift pad gets stuck when switching positions?
Solution: 1) Clean impurities 2) Add lithium-based grease 3) Check for buckle deformation
Q3: How to carry the 48kg YD21-016 efficiently?
Tips: 1) Correct two-person carrying posture 2) Use flat cart for distances over 5m 3) Utilize small fork lift assistance
Q4: How to handle scratches on chrome-plated ram?
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.
