In accordance with embodiments of the present disclosure, a travel joint includes a tube disposed at one end of the travel joint and a mandrel disposed at an opposite end of the travel joint. The mandrel is partially disposed in a hollow portion of the tube, and the tube and the mandrel are axially slidable relative to each other to extend or compress the travel joint. The travel joint also may include a housing coupled to the tube and disposed around the mandrel and a locking mechanism between the housing and the mandrel disposed in a position to selectively lock the mandrel and the tube in an axial position relative to each other to partially compress the travel joint. In some embodiments, the travel joint may include a fluid brake having a fluid chamber disposed between the mandrel and the tube to dampen axial movement between the mandrel and tube. |
