A dedicated climber tie-in for crane-assisted tree removals.
An arborist crane tie-in point gives a climber a dedicated, separate attachment on the crane line during crane-assisted removals. This version is built with Yale rope and is meant for crews who regularly work under a crane.
On crane jobs, a climber may need to ride or tie in to the crane line to reach the pick point. A dedicated tie-in point keeps the climber's connection separate from the rigging that holds the load, which is a core principle of crane-assisted tree work.
How and when a climber may be attached to a crane is governed by ANSI Z133, crane regulations, and the crane operator's procedures. Plan the job with the operator and qualified signal person before anyone ties in.
Crane-assisted removals can make dangerous trees much safer to take down, but only when the crane crew and tree crew share a clear plan. Agree on signals, load weights, cut sequence, and where the climber will be at every pick. Keep the tie-in point stored with your life-support gear and check it before every crane job.
Inspect the rope, terminations, and any hardware before every use. Retire it after a shock load or any damage. Never use it as a rigging sling, and keep it with your life-support gear, not the rigging kit.
See other friction savers and tie-in points. Life-support gear must meet the applicable standard (ANSI Z133 and the manufacturer's instructions), be inspected before every use, and be used only by trained climbers.

No. It is a climber attachment only. Keep life-support gear separate from rigging.
