Crane Stability & Ground Pressure: CICA & CANZ Guidance
Ground pressure is one of the most critical aspects of crane operations — poor stability can lead to tipping, structural damage or catastrophic failure. Cranes for You includes this CICA & CANZ guidance in its Knowledge Centre because rigorous understanding and strict application of ground-pressure principles are fundamental to achieving Goal Zero in lifting, rigging and transport.
Key Principles in the Guidance
- Bearing pressure limits — CICA & CANZ define maximum permissible ground pressure under outriggers and crane mats.
- Soil classification & assessment — Guidance on determining soil type, compaction, and subsurface conditions to evaluate capacity.
- Skidding and cribbing — Recommended practices for cribbing, mats or timber support to reduce point load impact.
- Slope and surface checks — How to evaluate ground slope, side-slope stability, and travel path integrity for cranes.
- Load monitoring and verification — Techniques for measuring load distribution and verifying that ground pressure stays within safe limits.
Practical Relevance for Lifting Operations
Adhering to this guidance ensures that cranes operate safely—especially during outrigging and heavy lifts. Using correct ground-support systems and understanding soil behaviour protects against excessive settlement, equipment damage, and catastrophic incidents. This knowledge allows crane engineers, lifting supervisors and site managers to plan lifts more reliably, reduce risk, and ensure compliance with recognised best practices.
