摘要： Method and apparatus for handling a supported tubular string with a string elevator and a spider on a rig to prevent damaging contact between the string elevator and spider while facilitating further connections of add-on tubular segments. The string elevator and supported tubular string descend toward the spider until reaching a predetermined position. The process of setting the spider into engagement of the tubular string is automatically initiated in response to detecting the predetermined position of the string elevator. With the spider set, the string elevator can be unloaded. Optionally, the method may also automatically terminate the string elevator descent in response to detecting that the spider has been set. A preferred apparatus for detecting the position of the elevator includes a tilt switch secured to a fixed position along the length of the Kelly hose.

摘要： A tubular grip interlock system for ensuring that a tubular string is gripped by at least one of a first tubular gripping device and a second tubular gripping device includes a console having a panel forming a track having a first leg and a second leg; a first actuator operating the first tubular gripping device between an open and a closed position; a second actuator operating the second tubular gripping device between an open and a closed position; and a single control device movable along the track, the single control device operationally connected to the first actuator and operationally disconnected from the second actuator when the single control device is disposed along the first leg and wherein the single control device is operationally disconnected from the first actuator and operationally connected to the second actuator when the single control device is disposed in the second leg.
