I can't do optional tomb becasue one cart is stuck

at hidden raven she says that i should be able to push the cart but i can't even tho i did pushed another one

Hidden Ravine? There is no tomb there. Do you remember the name of the Tomb? There's only 2 tombs with carts & that's the Red Mine in the Soviet copper mill & Pit of Judgment in Geothermal Valley. In Red Mine, you don't push the cart, you have to pull it down. In Pit there's 2 carts to push down. 1 is easy to figure out. The 2nd one you have to climb up above where the cart is located, lower the platform to the 1st level, turn the platform & push the cart on to that platform and turn back to the position is was in when you lowered it. Once you do that, you raise the platform back up to the 2nd level, the cart should already be in the correct position, and push it down. Cut scene does the rest.
Let me know if this helps or if you remember the name of the tomb

Check the platform! It has to face the right way because the other way has a little fence at the end that pops up when you're finished rotating it.

You hold the "C" button to get up out of the chair, for at least a second or 2.
Skyrime is correct, the platform the cart rests on, must be turned twice. Did you turn the wheel to the side of the platform. These wheels (3 in all) allow Lara to turn the platforms in order to push them off
