Abstract: The present application pertains to a system comprising a multi-axle trailer with a front and a rear. The a multi-axle trailer comprises at least one lift axle configured to be raised or lowered to distribute weight, to increase trailer deflection during a turn, or both. A jeep is mounted between the trailer and a tractor wherein the jeep is configured to decrease weight on one or more axles. A booster is mounted to the rear of the multi-axle trailer. The system is configured such that during raising of the at least one lift axle an increase in air pressure to one or more other axles is increased to offset weight.

Abstract: A roller assembly for a coiled tubing guide assembly has a roller having an interior; a shaft within the interior of the roller. The shaft is configured to attach to a coiled tubing guide assembly while allowing the roller to roll. One or more bearings are within the interior of the roller. A bearing retainer is configured to prevent bearing debris from leaving the roller interior. This prevents bearing debris from affecting or damaging other components of the coiled tubing unit.

Abstract: The present application pertains to a method and system for coiled tubing injector chain management on a coiled tubing unit. Advances in tubing technology combined with lack of operator training have been detrimental to injector longevity. Optimizing chain and equipment life requires operating parameter control. This method utilizes feedback from loads on the injector chassis to adjust chain traction and tension to optimal levels to extend equipment life.

Abstract: An auxiliary dolly is attachable to the rear of a primary trailer. The auxiliary dolly includes a first portion attachable to the primary trailer; a second portion comprising a chassis with one or more axles with wheels and a payload portion on the chassis. The payload portion is configured to pivot relative to the chassis with one or more axles with wheels of the second portion. A pivot point is at the point where the first portion is coupled to and movable relative to the second portion. Two or more cylinders are configured to pivot the payload portion of the second portion relative to the chassis with one or more axles with wheels of the second portion he pivot allows the payload portion to be substantially aligned with the primary trailer while turning.

Abstract: An injector tilt and stowage mechanism has a potential safety concern if retaining pins are not in place when the injector is tilted for stowage. A mechanical latching system is designed that secures the injector and simultaneously engages or disengages the hydraulic system to prevent movement in an unsecured condition.

Abstract: The present application pertains to an automated control system for controlling and adjusting reel tension on a coiled tubing unit. The system may comprise real time data received from one or more sensors, input by an operator, or calculated.
