Product Details
The YD21-007 to YD21-010 Economic Toe Jack Series addresses challenges in low-clearance lifting, high-clearance support, and extreme environment adaptability with dual-mode load-bearing, full-scenario adaptation, and enhanced safety durability.
Dual Load-Bearing Modes + Wide Height Range
- Toe Lifting as Low as 17mm: Directly extends into tight spaces under houses (15-20mm clearance) and mechanical bases (20-30mm clearance)
- Head Support as High as 510mm: Provides over 40cm operating space for bridge component splicing and large machinery installation
High-Strength Structure + Full Temperature Range Adaptation
- Special Steel Ram: ≤0.1mm permanent deformation after 100,000 fatigue tests
- Welded Base: No cracking when supporting 14T bridge components
- Wide-Temperature Hydraulic Oil: Operates from -30℃ to 80℃ without solidifying or leaking
Lightweight Design + Safety Protection
- Lightweight: Starting from 8.5kg (YD21-007), operable by one person
- Safety Features: Overload safety valve and diamond-pattern anti-slip base (friction coefficient ≥0.8)
Application Scenarios
Small House Translation (YD21-007)
Scenario: Translating a 15-ton house with 18mm foundation clearance
Result: 40% efficiency increase by eliminating foundation damage
Machine Tool Installation (YD21-008)
Scenario: Installing 8-ton machine tool with 25mm base clearance
Result: 50% efficiency increase with dual load-bearing modes
Bridge Component Splicing (YD21-009)
Scenario: Splicing 12-ton bridge components with 30mm clearance
Result: 30% accuracy improvement with rust-resistant design
Hull Section Support (YD21-010)
Scenario: Supporting 18-ton hull sections with 30mm clearance
Result: Reduced equipment needs with 510mm maximum height
Frequently Asked Questions
Q1: Can the YD21-008 (5T toe load) lift an 8-ton machine tool?
Answer: No, the overload protection will trigger at 5.5T. For 6T loads, use YD21-009 (10T) or higher models.
Q2: What causes the toe/head to stick during operation?
Solution: Check hydraulic oil level, clean oil circuit, or treat ram rust with 400-grit sandpaper and anti-rust oil.
Q3: How to carry the 48.5kg YD21-010 efficiently?
Tips: Use a flat cart, proper lifting posture, or hoisting assistance through the top hole.
Q4: How to handle fine cracks at base welds?
Action: Stop use immediately and contact manufacturer for professional arc welding repair.
