Automatic wire spooling control
Systems and methods can be used in connection with a wellbore environment for automatically controlling wire being spooled around a drum. A system comprising a spooler, a sensor assembly, and a communication link can be used to adjust the position of wire being spooled around a drum. A first motor can control the spooler and a second motor can control the sensor assembly. The spooler can be positioned to control spooling of wire around the drum as the drum rotates to reel in wire. The sensor assembly can be configured to detect a distance between the sensor assembly and the wire being spooled. A communication link can communicatively couple the sensor assembly with the first motor and the second motor to control movement of the spooler and the sensor assembly relative to the drum based on the distance detected by the sensor assembly.
Rope winch
The present invention relates to a hoisting winch, in particular to a hoisting gear winch, having a hoisting drum whose winding region is bounded by two lateral flanged wheels, wherein at least one further flanged wheel is provided between the lateral flanged wheels for dividing the winding region into at least two part winding regions, wherein the cable can be guided beyond the named further flanged wheel into the at least two part winding regions. It is suggested in accordance with the invention to move the hoisting drum and/or a transverse cable guide arranged in front of the hoisting drum transversely to the longitudinal direction of the running in/running off cable approximately in the longitudinal direction of the drum and/or to adjust the angular position of the hoisting drum transversely to the longitudinal direction of the drum with respect to at least one transverse axis.

RELIABLE SPOOLING FOR A MOTORIZED LIFTING/PULLING DEVICE
An apparatus for providing reliable spooling for hoists, winches, and other pulling and/or lifting devices is disclosed. In one embodiment, such an apparatus includes a motor and a drum rotated by the motor to draw in or let out a line from the drum. The drum includes a groove formed in an outer surface thereof to accommodate the line. A roller is provided to place pressure on the line against the drum. This roller is powered to assist the drum in spooling the line onto and off of the drum. In certain embodiments, the roller is driven by a gear that engages teeth on the drum. In other embodiments, the roller is driven by a wheel that is rotated by the drum. A corresponding method is also disclosed and claimed herein.
ROPE GUIDE OF ROPE DRUM IN CRANE
A rope guide of a rope drum in a crane surrounds the rope drum and keeps the hoisting rope in a spiral rope groove of the rope drum when the hoisting rope is wound into the rope groove or unwound from it. The rope guide includes a body that is made up of several parts and surrounds the rope drum; a rope guide element at a winding/unwinding point of the hoisting rope; a hoisting rope retainer for pressing the hoisting rope into the rope groove; and several guide members distributed on the circumference of the rope guide and arranged to move on a surface of the rope drum or the hoisting rope to guide the hoisting rope being wound onto the rope drum or unwound from it. The body is a chain-like entity including chain links interconnected to form a ring-like entity extending around the entire rope drum, to which entity the rope guide element, hoisting rope retainer and control members are installable.

LINE TRACTION FOR A MOTORIZED LIFTING/PULLING DEVICE
An apparatus for providing reliable line traction spooling for hoists, winches, and other pulling and/or lifting devices is disclosed. In one embodiment, such an apparatus includes a motor and a drum rotated by the motor to draw in or let out a line from the drum. The drum includes a groove formed in an outer surface thereof to accommodate the line. A roller is provided to place pressure on the line against the drum. A roller consists of at least one indentation or protrusion on an outer surface to assist the drum in spooling the line onto and off of the drum. In certain embodiments, the roller is patterned in order to improve line traction. In other embodiments, a line is compressible in order to improve line traction.

Portable winch
A portable winch and method of use is shown. One advantage of winches shown includes an ability to lower a boom or boom sections into limited access exit pit for winching operations such as pipe bursting. Sectional boom designs shown provide the ability to easily raise and lower a boom large distances without the need for a single long boom. Selected winch designs shown include flexible inserts between the boom and the winch frame that help resist damage from unforeseen shifting of the device during operation. Designs and methods shown also include multiple pulleys on a boom end unit. Fasteners are shown that reduce build up of debris.
