The Drawworks

The big hoist that raises and lowers tons
of drill pipe and other tools out of and
into the hole is a vital piece of equipment
in the hoisting system. This program
explains that while the drawworks is a
large, rugged, and dependable device,
the rig crew must properly maintain it
to provide reliable day-in-and-day-out
service. Besides covering conventional
DC drawworks, this audiovisual also
shows the latest AC drawworks. Produced
