摘要： An improved cable feeder uses tractor type drive belts and compressed air to propel cable through a conduit. The axial force applied to the cable is sensed with a strain gauge near the conduit or a pressure detector in a hydraulic system powering the drive belts. If excessive force is applied, hydraulic fluid is diverted from the drive belts. The radial force applied to the cable is limited by a calibrated spring. The feeder can also be arranged in a mid-assist configuration. Conduits and the cable are sealed to maintain air pressure. A by-pass pipe is provided to convey pressurized air from a first conduit to a succeeding conduit.

摘要： A gripper block for use in grippingly engaging coil tubing, pipe, rod, cable, or like objects having various outside dimensions for ultimately applying a longitudinal load thereto. The subject gripper block has an attachment point preferably at or near the center of the block body to enable attachment to at least one endless chain of an injector apparatus. The gripper block further has a pair of gripper surfaces formed thereon, these gripper surfaces are generally planar and tilted away from each other so as to diverge away from the tubing to be gripped at approximately 90 degrees. The gripper surfaces thus preferably provide a V-shaped engagement configuration which is quite effective in gripping objects of differing outside dimensions with no or minimal scarring of such objects.

摘要： A method and apparatus for the transfer of loads from a vessel that moves with heavy seas to a stationary or mobile installation by the use of at least one lifting cable and at least one hoisting mechanism, where the load, in a starting position, stands on a rack on the vessel. The load transfer takes place at an instant when the load has only insignificant kinetic energy, as the gripping mechanism is activated in a controlled manner at the instant to lock the load to the lifting cable. At the same instant the rack collapses and immediately establishes a distance between the load and the vessel, thereby suspending the load on the lifting cable.

摘要： An electrically powered oil well pipe extractor includes a standard well servicing rig having a winch driven by a combustion engine. An auxiliary vehicle has an electric motor connected through a transmission or torque convertor, through a drive shaft, to the winch on the well servicing rig. The combustion engine is disengaged from the winch and the winch is driven by the electric motor on the auxiliary vehicle during pipe extraction operations at a well site having electric power available. Exhaust emissions and noise are significantly reduced.

摘要： An apparatus for increasing the available hook raising and lowering distance is attached to a crane or other lifting structure having a boom and at least one lifting tackle utilizing at least one lifting line connected to a prime mover. The apparatus utilizes a support means attached to the crane boom substantially at the connection point of an existing upper tackle. A fixed, lower gripper platform is suspended from the support means and has at least one linear winch grip mounted thereon. A movable, upper gripper platform is connected to at least one lifting line associated with the lifting tackle. The upper gripper platform has at least one linear winch grip mounted thereon. The upper gripper platform is also adapted to reciprocate between the lower gripper platform and the upper tackle in response to the prime mover drawing in or paying out the lifting line. At least one extended load line for attachment to a load passes through the linear winch grips on the lower and upper gripper platforms. Take up reels or other such means take up and let out the extended load line. A control means connected to the linear winch grips mounted on the upper and lower platforms causes these grips to individually and selectively release or grip the extended load line.

摘要： An apparatus for pulling an electric cable or wire between two locations such as along the length of a pipeline is described including an engine mounted in the box of a truck and having a pinch wheel operatively connected thereto. A torque balanced pulling rope is extended around the pinch wheel and passes through spaced-apart sheaves mounted on the pipeline. The free end of the rope is connected to the electric cable which is to be pulled along the length of the pipeline. The rope passes from the pinch wheel to an automatic rope tender mounted on a trailer positioned rearwardly of the truck. The automatic rope tender is operated at a slightly greater grade than the sheave wheel and deposits or drops the rope into a storage container. The automatic rope tender includes means for lifting the storage container from the ground to enable the container to be moved from one location to another.
