A CIPP liner reel system for managing the utilization and deployment of CIPP liners. The CIPP liner reel system generally includes a frame connected to a reel and drive unit. The drive unit is connected to the reel to control the rotation of its core. This core contains an opening that provides access to a connector unit within the core. This connector unit can be used to connect the reel to the end of a CIPP liner using a strap. Rotation of the core causes CIPP liner to wind on to or unwind from the reel. The reel may also contain a left guide member and a right guide member to assist in controlling the process of winding and unwinding the CIPP liner. The frame may also include a tractor connector that enables the CIPP liner reel system to be coupled to and transported by a tractor without affecting its operation.

In a conventional method for extracting a cable, a power cable is reeled in by rotating a reel drum using a drive motor, and therefore there are cases where a power cable in a conduit cannot be extracted with the driving force of the drive motor when a large extraction force is required to extract the power cable from the conduit. The present invention is capable of directly transmitting, to a cable drum (5), a rotational force of rubber tires (9) whose outer circumferential portions are made of elastic rubber, by rotating the rubber tires (9) while bringing the rubber tires (9) into intimate contact with outer faces of the cable drum (5), and is capable of reliably rotating the cable drum (5).

The patent discloses a winding device with a speed regulating mechanism. The winding device with a speed regulating mechanism includes a device body and a winding wheel installed on the device body. The speed regulating mechanism is arranged on one side of the winding wheel and includes a transmission gear set and a speed regulating shifting rod. The transmission gear set includes a sliding output gear and a speed regulating transmission member. According to the winding device with a speed regulating mechanism, the speed regulating mechanism is installed in the winding device, through the regulation of the speed regulating shifting rod, the transmission efficiency of a water turbine can be changed, and the regulation of various winding speeds can be achieved. Moreover, an idling function can be fulfilled after an output shaft is pulled through a handle, which makes the winding wheel suspend moving.

The application relates to a cable drum support for rotatably supporting a cable drum, including a cross beam, on which two holding arms are arranged, which are aligned parallel to one another, wherein each holding arm has a respective laterally protruding and rotatably supported bearing pin on a free end, wherein the bearing pins are arranged aligned with one another on the holding arms so as to face one another and aligned parallel to the cross beam, and wherein at least one of the holding arms is shiftably supported along the cross beam. The cable drum support further including at least one actuatable actuator, which is formed to shift at least the one of the holding arms and/or to apply a torque to at least one bearing pin for rotating about its longitudinal central axis.

A manifold is part of the hydraulic system of a transport vehicle and controls both the product pump from the tank for unloading product and a hydraulically powered and controlled hose reel. The manifold includes a high pressure input port and a main return port tied into the hydraulic circuit on the vehicle, as well as two ports for the product pump and two ports for the hose reel. Control valves for both the product pump and the hose reel are mounted on and connected within the manifold block. The control valve for the hose reel preferably allows either forward (winding) or reverse (unwinding) of the hose reel under hydraulic power, as well as easy free spooling of the hose reel. A priority flow valve is also mounted on and connected within the manifold block, providing a higher flowrate to the product pump than to the hose reel motor.

A coiled tubing unit includes a coiled tubing assembly and a slickline assembly sharing an axis of rotation with the coiled tubing assembly. A shaft of the coiled tubing assembly is received by bearings on a slickline drum of the slickline assembly and extends through an interior of the slickline drum. A swivel joint connection is rotatably affixed on an end of the main shaft as it exits the interior of the slickline drum, thus allowing for introduction of fluid or cabling into the main shaft and into the coiled tubing. The coiled tubing drum and slickline drum can rotate independently and are powered independently of each other. The coiled tubing and slickline assemblies are preferably affixed to a removable module, the removable module being positioned on a skid having a power unit and appropriate controls.

In a reel assembly, a repositionable level wind may be selectively coupled to a drum to enable powered rotation of the level wind from a first position to a second position. In some embodiments, the assembly may include two arced guide rails, a rotating adjustment arm, a roller bracket, a winding assembly and two fork plates, which may be adjustably mounted on the drum. In operation, the fork plates may be moved to an engaged position that couples the adjustment arm and the roller bracket to the reel flanges so that rotation of the reel causes the winding assembly to be rotated along the guide rails. Once a desired position is reached, the adjustment arm and roller bracket may be bolted to the guide rails and the fork plates may be moved to a disengaged position to allow the reel to rotate independently of the winding assembly.

A system is provided including a coiled tubing reel apparatus including a reel drum for storing a coiled tubing string spooled on the reel drum and a hydraulic reel drive motor that controls rotation of the reel drum. The system further includes a reel controller that determines an estimated reel back tension for a portion of the coiled tubing string between the reel apparatus and the injector based on a set of parameters related to a coiled tubing operation. The reel controller determines a target reel back tension to be applied to the portion of the coiled tubing string by adjusting the estimated reel back tension based on a historical job dataset. The reel controller then determines and sets a target hydraulic pressure of the reel drive motor to achieve the target reel back tension in the portion of the coiled tubing string.
