Soil Pressure & Lift Plans: What Changes Between a 50-Ton and 500-Ton Crane?
How to read outrigger pressure and operating radius when scaling from a 50-ton to a 500-ton crane on Jubail and Dammam sites.
The Load Chart reading guide explains the symbols. Here we connect the numbers to real fleet classes: a 50-ton crane suffices for a mid-size steel frame, while a 500-ton is booked for plant shutdowns, not building facades.
Operating Radius Eats Capacity
A 40-ton piece at a 22 m radius can require a 160–200-ton crane class, not a simple 80-ton. Always send a site plan with the crane's standing position and the load's pick and set locations.
Outriggers Are Not Decoration
Classes from 200 tons upward place concentrated point loads that crack poor asphalt. Use engineered steel mats and calculate bearing pressure before the crane arrives on site.
Crane Class Ladder to 500 Tons
25, 50 & 80 tons for urban works. 130–160 tons for bridges and precast units. 200–400 tons for refinery vessels. 500 tons reserved for industrial emergency lifts.
