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.

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.
