As soon as Lara has obtained Rope Arrows, she can perform the rope pull. This can be used to tear down blockades, supporting beams or simply pull objects or - only in Tomb Raider (2013) - enemies.
Tomb Raider (2013)
Rise of the Tomb Raider
In Rise of the Tomb Raider Lara obtains the rope arrows during her trip to the Gulag in the level Prison Break. Immediately after finding these she will have to use the rope pull to escape her prison cell. She will be using it a couple of times in the Soviet Installation region to optionally tear down watchtowers when escaping the Gulag, to open caves and to open the entrance to the Copper Mill.
Shadow of the Tomb Raider
One of the first opportunities to use Rope-Pulling is during the level Hunter's Moon.
