Economic Toe Jacks (2-15T): Low/High Clearance for House/Machinery/Shipyard Work
| Common Parameters | Specific Description |
|---|---|
| Product Type | Economic toe jacks, covering 2T/5T/10T/15T toe load specifications. Designed for dual scenarios of low-clearance lifting and high-clearance support, serving heavy-duty operations including house moving, machinery installation, shipyards, bridge construction, and plant construction. |
| Core Common Configurations |
|
| Model | Toe Capacity (TON) | Head Capacity (Ton) | Min./Max. Toe Height (MM) | Min./Max. Head Height (MM) | Core Adaptable Scenarios |
|---|---|---|---|---|---|
| YD21-007 | 2 | 3 | 17/132 | 235/350 | Light machinery installation, small house translation |
| YD21-008 | 5 | 6 | 27/147 | 293/413 | Medium-sized machine tool positioning |
| YD21-009 | 10 | 14 | 31/176 | 327/472 | Heavy equipment relocation, bridge component splicing |
| YD21-010 | 15 | 20 | 31/196 | 345/510 | Large machinery installation, hull section support |
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.
- 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
- 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: 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)
Scenario: Translating a 15-ton house with 18mm foundation clearance
Result: 40% efficiency increase by eliminating foundation damage
Scenario: Installing 8-ton machine tool with 25mm base clearance
Result: 50% efficiency increase with dual load-bearing modes
Scenario: Splicing 12-ton bridge components with 30mm clearance
Result: 30% accuracy improvement with rust-resistant design
Scenario: Supporting 18-ton hull sections with 30mm clearance
Result: Reduced equipment needs with 510mm maximum height
Answer: No, the overload protection will trigger at 5.5T. For 6T loads, use YD21-009 (10T) or higher models.
Solution: Check hydraulic oil level, clean oil circuit, or treat ram rust with 400-grit sandpaper and anti-rust oil.
Tips: Use a flat cart, proper lifting posture, or hoisting assistance through the top hole.
Action: Stop use immediately and contact manufacturer for professional arc welding repair.
