The onsite yard

Three working scenes, drawn to scale at 1:250 with dimensions and a title block: a crawler crane with a hanging leader pitching and driving a precast concrete pile to a Hiley set, a rotary rig drilling, casing, caging and concreting a bored pile, and a crawler crane lift you can drag to any radius against its load chart. Change the inputs and watch the record build.

Scope & limitations

Illustrative simulations for teaching and planning conversations. Soil resistances, drilling rates and the load chart are typical values, not a design or a manufacturer's chart.
