How to Rate UHMWPE Crane Outrigger Pads Against Load Chart

Overview

This guide covers the practical steps to rate uhmwpe crane outrigger pads against load chart. JSLT GroundMat produces engineering plastic components in UHMWPE, HDPE, PA, POM and PTFE — full-process fabrication from raw sheet to CNC-machined parts.

Step-by-step procedure

1. Pull crane load chart. OEM load chart shows outrigger reaction at boom angle and radius.
2. Find worst-case pick. Identify lift configuration with maximum outrigger load.
3. Calculate pad ground pressure. Outrigger load ÷ Pad area = pad ground pressure.
4. Confirm < ground capacity. Pad ground pressure must be < soil bearing capacity with 2× safety factor.
5. Document and certify. Issue lift plan with pad calculation; site supervisor signs.
