Rigging 2

COURSE DESCRIPTION

Many jobs performed on transmission and distribution systems require heavy loads to be rigged so that they can be lifted, moved, and stabilized while work is being done. This course identifies basic rigging equipment and discusses guidelines for rigging a job safely. It also demonstrates rigging methods using different types of rigging equipment. The following procedures are covered: rigging a transformer, rigging a running corner, changing out a crossarm, and transferring secondary lines.

COURSE GOALS

  • Identify the safety concerns associated with rigging.

  • Describe how to use several types of rigging tools and equipment.

  • Describe rigging and work methods used to replace a transformer, secure a conductor in place on a running corner, change out a crossarm, and move secondary lines.
