Outrigger Pad
Request InformationProduct Details
Outrigger pads are high-performance engineering components designed to distribute ground pressure from hydraulic outriggers on heavy equipment—including cranes, concrete pumps, and aerial work platforms (AWPs). Manufactured from HDPE or UHMW-PE, they replace traditional steel or wooden pads with superior strength-to-weight ratios, corrosion resistance, and lifecycle efficiency.
1. Core Applications & Solutions
| Scenario | Pain Points | Solution | Case Example |
|---|---|---|---|
| Construction | Sinking/tilting on soft ground (silt/sand) | Load distribution via UHMW-PE pads | Crane stabilization on riverbanks |
| Ports/Docks | Saltwater corrosion of metal pads | 0% moisture absorption; corrosion resistance | 80% maintenance cost reduction |
| Mining/Quarrying | Rapid wear; heavy repositioning burden | UHMW-PE: 8× steel wear resistance; 70% lighter | Rapid deployment in rocky terrain |
| Bridge/Tunnel | Ground pressure damages structures | Custom sizes for precise load distribution | Foundation protection near piers |
| Emergency Ops | Slow deployment of wooden pads | Modular/foldable designs for stacking | Disaster response mobility |
2. Material Comparison: HDPE vs. UHMW-PE
| Property | HDPE | UHMW-PE | Advantage |
|---|---|---|---|
| Density (g/cm³) | 0.93–0.94 | 0.93–0.94 | 70% lighter than steel |
| Load Capacity | Standard | ↑ 50% vs. HDPE (same thickness) | Handles ultra-heavy equipment |
| Wear Resistance | High | 8× steel; 4× nylon | Ideal for abrasive surfaces |
| Impact Resistance | Good (−40°C to +80°C) | Excellent (−169°C to +80°C) | No brittle fracture in extreme cold |
| Cost Efficiency | Lower upfront cost | 3–5× longer lifespan | 60% lower lifecycle cost vs. steel |
3. Technical Specifications & Load Table
Max loads assume firm ground; soft ground reduces capacity by 30–50%. All dimensions customizable.
