Climbing up the device - After the cut scene, go around the support and approach the edge of the ledge facing the device.

When a platform passes in front of you, jump onto it.

Facing the device, wait for another platform to pass just above you and jump to grab it.

Pull up and approach the device. Jump to grab one of the handholds of the first ring on the device. When one of the handholds of the second ring above is ready to pass, jump straight up to grab it.

Wait until the ring passes beneath a series of handholds. When it does so, climb up the first set of handholds.

Jump straight up to grab the second set of handholds and traverse to the left.

Climb up until the third handhold and traverse around the corner to the left. Then jump up to grab the lone handhold.

Again, jump straight up to grab the last set of handholds and traverse to the right around the corner. Now climb to the top.

At this point, a situational adrenaline begins. Natla flies behind Lara and throws many fireballs. Quickly jump up to grab one of the handholds of the ring above in order to avoid the bolts.

Destroying the third power mechanism (and angled support) - Wait for the ring to rotate and bring you above the third angled support.

When it does so, release to land on the support.

You will start sliding down and end up in front of the third power mechanism. Press the Interact button to use the Hammer and smash the mechanism.
