摘要： A coiled tubing injector, rollers on the backside of grippers on a gripper chain pass over at least one shallow groove or depression formed in, or gap between segments of, a planar roller contact surface of a skate, thereby momentarily removing or reducing the force being applied by the skate to the grippers as the grippers pass through at least one predetermined location within a gripping zone of the coiled tubing injector. The reduction or removal of the force on the grippers allows the grippers to reset their positions on the tubing at one or more predetermined locations in order to accommodate changes in the strain caused by changes in stress as the tubing moves through the injector.
摘要翻译：连续油管注射器，夹持器链上的夹持器背面的辊通过在滑冰板的平面辊接触表面上形成的或在间隔之间形成的至少一个浅槽或凹槽，从而瞬间去除或减小力当夹具穿过连续油管注射器的夹紧区域内的至少一个预定位置时，该滑板由滑板施加到夹具。夹持器上的力的减少或去除允许夹具在一个或多个预定位置处重新设置在管道上的位置，以便适应当管道移动通过喷射器时由应力变化引起的应变变化。

摘要： A mast for lifting and suspending over a wellhead a coiled tubing injector and blow out preventer is pivotally mounted on a rear portion of a truck. The mast has two side-by-side telescoping legs that extend and retract synchronously. When in a retracted position, the blow out preventer and coiled tubing injector are attached to the mast, between the legs, and legs of the mast extended to lift the equipment.
