G20 fixed-mount hydraulic-crane simulator
A fixed-mount hydraulic-crane simulator with accurate load physics. Built to keep practicing after the G20 Fastmontert hydraulisk kran course ended.
These tools were built with desktop in mind and may not work well on mobile.
Overview
A browser-based G20 fixed-mount hydraulic-crane simulator I built with accurate load physics. I use it to keep practicing after the G20 Fastmontert hydraulisk kran course ended, when I no longer had access to a real crane but still wanted to sharpen the feel.
My focus was the behaviour of the load: swing, momentum, anticipation, stopping a swing cleanly during slew and luff. Things that only really click with hours on the controls. A place for me to put those hours in, where mistakes cost nothing.
What it taught me
Writing the physics forced me to understand why the load behaves the way it does on a slewing boom: how the hook responds to rotation, why a smooth swing comes from anticipation rather than reaction. A place to keep the feel alive between sessions, where mistakes cost nothing.
