Abstract
A vertical pipe handler with pivoting arms for a drilling rig can include a central support and a central support center line. The vertical pipe hander can grab a tubular with top and bottom pipe grabbers, and lift the tubular using a bottom non-rotating collar and a bottom rack and bottom pinion lift mechanism. The tubular can be vertically positioned before being moved downward; thereby allowing for a next tubular in a series to be positioned and inserted.
