Heavy Rigging in Portland

Before you request quotes for heavy rigging in Portland, it helps to know how the work is usually done and which questions separate careful providers from the rest.

Overview

Rigging is the equipment and practice of attaching loads to lifting devices and moving them safely. Heavy rigging covers large industrial loads, machinery and structures, using slings, shackles, spreader bars, gantries, jacks and skates.

Rigging contractors plan the lift or move, select equipment, determine attachment points and coordinate with cranes or other lifting systems.

Qualified riggers and well-maintained gear are essential.

The usual process

  • Assessing load and attachment points.
  • Selecting rigging gear.
  • Planning the move.
  • Executing the lift or move.
  • Setting the load.

What affects the outcome

  • Center of gravity matters.
  • Rigging gear must be rated.
  • Qualified riggers required.
  • Space constraints affect methods.
  • Insurance requirements.
