CPS Screening Tool
80% utilisation limit · final lift-plan verification required
Pad Size Calculator

Screen Pad Size
For Your Lift

Enter the verified maximum outrigger reaction and a site-assessed ground-capacity value. The tool screens candidate CPS pads against bearing area and manufacturer-listed pad capacity; it does not approve a lift or confirm the ground.

Verified Maximum Reaction Per Outrigger

Use the highest outrigger reaction for the planned lift from manufacturer data, the duty chart or the lift plan. Gross crane or vehicle weight divided by the number of outriggers is not a valid substitute.

Tonnes
Enter the load in tonnes (e.g. 12 for a 12-tonne outrigger load)

Ground-capacity input

Use the assessed allowable bearing pressure for the actual support and outrigger position. A surface name alone does not establish capacity.

Capacity unknown? Ask what information is needed. Do not select an assumed number as proof of suitability.

Still not sure which pad fits your job?

Ground and lift configurations vary. We can help shortlist a product, but the appointed person and competent ground assessment must confirm the final pad for the planned lift.

Already have a pad? Use the Ground Bearing Calculator to screen calculated pressure against an assessed ground input, then verify the final design.

Screening limitation: The selectable ground values are CPS examples, not site design values or a substitute for ground investigation. The calculation limits pressure to 80% of the entered value as a screening reserve; this is not a universal factor of safety. The lift plan must verify the reaction, ground, float geometry and exact manufacturer-listed pad capacity.
