Methods and apparatuses for mounting and/or removing carrier blocks from coiled tubing injector chains are needed. The carrier blocks are operable for supporting coil tubing grippers. The method and/or apparatus utilizes an assembled coiled tubing injector head chain assembly and/or mounting or removing the carrier blocks with respect to the coiled tubing injector head chain assembly.

A system for processing a cable end of a cable. The system includes: a pallet delivery system; a cable processing module; a pallet supported by the pallet delivery system; an on-pallet dual-belt cable feed mechanism configured for linear feeding of the cable end into the cable processing module; and an off-pallet electric motor operatively coupled for driving circulation of a pair of belts of the dual-belt cable feed mechanism. The cable processing module includes cable processing equipment configured to perform an operation on the cable end and a computer. The computer is configured to: (a) cause the dual belts to circulate in respective cable pushing directions to cause a specified length of cable to be inserted into the cable processing equipment; (b) activate the cable processing equipment to perform an operation on the inserted end of the cable; and (c) cause the dual belts to circulate in respective cable pulling directions to cause the specified length of cable to be withdrawn from the cable processing equipment.

An electric wire processing apparatus includes a gripping mechanism that grips a part of an electric wire, a driving mechanism that drives the gripping mechanism, an electric wire winding mechanism that winds the electric wire, and a rotating mechanism that rotates and drives the electric wire winding mechanism. The electric wire winding mechanism includes a winding drum, an electric wire clip provided on the winding drum to hold a leading end of the electric wire, and a holding member that holds an electric wire bundle. The driving mechanism moves the gripping mechanism toward the electric wire clip to hold the leading end on the electric wire clip, the rotating mechanism rotates the winding drum so that the electric wire is wound around the winding drum, and the holding member holds the electric wire bundle wound around the winding drum in the annular shape.

A device for towing very long tubular objects, comprises: pulling means capable of driving, by friction, the object in a towing direction, gripping means capable of exerting a load on the pulling means to keep the pulling means and the towed object in continuous contact; the gripping means being driven by a relative movement relative to the towed object in a direction opposite to the towing direction, driving means, capable of driving the pulling means and the gripping means in a coordinated manner to ensure a continuous and uniform pulling of the object, further comprising setting means, capable of adjusting the load exerted on the pulling means.

A device for towing very long tubular objects comprises a casing and an assembly which can be fixed removably to the casing. The removable assembly comprises: pulling means capable of driving in their movement, by friction, the object in a towing direction, gripping means capable of exerting a load on the pulling means to keep the pulling means and the towed object in continuous contact; the gripping means being driven by a relative movement relative to the towed object in a direction opposite to the towing direction. The casing comprises driving means, connected removably to the pulling means and gripping means and configured to drive in movement the pulling means and the gripping means in a coordinated manner to ensure a continuous and uniform pulling of the object.

A tensioner pad assembly is adapted to be mounted on an endless track of a tensioner to frictionally clamp an elongated product supported and moved by the tensioner. The pad assembly includes a carrier member and a pair of gripping members, which gripping members can with their carrier member mating surfaces be mounted in multiple discrete gripping positions on gripping member mating surfaces of the carrier member. The mating surfaces form interlocking structures adapted to transfer a squeeze force from the carrier member to the gripping members. The interlocking structures provided on the carrier member define the multiple discrete gripping positions. The gripping member mating surfaces extend at an angle relative to each other, such that the multiple discrete gripping positions differ in their distance to the base portion as well as in their distance to the imaginary plane of the carrier member.

A cable engine module for conveying cables or pipes includes a frame, traction wheels, and drive means for driving the traction wheels. The frame has a longitudinal direction between a first and second longitudinal end, a traverse direction between a first side a second side, and a front side. The frame supports the traction wheels on the front side of the frame, and the traction wheels are spaced apart in the longitudinal direction of the frame and convey a cable or pipe in the transverse direction. The frame is provided with first connection means on the first side of the frame and second connection means on the second side of the frame. The first connection means are attached to a second connection means of an identical cable engine module, and the second connection means are attached to a first connection means of an identical cable engine module.
