A spindle can include a rotation element for rotating the spindle; a spindle lock and safety latch to limit rotation of the spindle; a wire guide to guide the wire; a pipe guide to guide a water pipe connected to the pump; a pipe catch to catch the pipe if the wiring fails; and a drill abutment that can abut a drill used to rotate the rotation element. | 11-07-2013 |
| 20130292618 | Well pump extractor - A well pump extractor, which includes a base rotably supporting a spindle, a pipe guide, and a pipe catch, extracts a well pump from within a well by winding electrical wiring attached to the pump around the spindle. During an extraction, a pipe guide guides the path of water pipe connected to a pump. If the electrical wiring fails mechanically during an extraction, the pipe catch catches the water pipe, which prevents the pump from falling to the bottom of the well. | 11-07-2013 |
| 20130334479 | Rope Anchor For A Winch - A winch includes a motor and a rotatable drum drivingly attached to the motor. The rotatable drum includes an anchor pocket therein. A cable includes a proximal end connected to the rotatable drum by an anchor received in said anchor pocket with the cable wrapped around the anchor. The anchor includes a first slot in a surface thereof and the rotatable drum includes a second slot therein adjacent to the anchor pocket that allows access to the first slot in the anchor. An edge of the second slot forms a fulcrum point for a pry tool inserted into the first and second slots for freeing the anchor from the anchor pocket. | 12-19-2013 |
| 20140034887 | BRAKE, SHEAR AND CABLE MANAGEMENT SYSTEM AND METHOD - The invention relates to a brake, shear and cable management system and method, which is attachable adjacent to a reeling-type drum to effectively brake and cut cable, such as drilling line, boring line, electrical line, fiber optic line or the like. The brake, shear and cable management system includes a cable management assembly, a cable brake assembly and a cable cutting assembly used in conjunction to manage, retain and sever a spent portion of cable upon the drum. | 02-06-2014 |
| 20140166952 | HOIST - A hoist includes a cable configured to lower and to raise a load, and a drum arranged to be rotatably seated about an axis of rotation and configured to wind up and to unwind the cable. The drum comprises a flanged wheel which comprises a securing device configured to secure the cable. The securing device comprises a cable-accommodating block comprising an abutment surface, and a cable clamp. The cable-accommodating block is affixed to the flanged wheel in a direction of tension of the cable and is configured to have the cable be passed there-through. The cable clamp comprises a counterpart abutment surface. The cable clamp is configured to be affixed to the cable. The abutment surface of the cable-accommodating block is configured to be contacted with the counterpart abutment surface of the cable clamp under an effect of a tensile force. | 06-19-2014 |
| 20140264209 | HOIST AND WINCH CABLE ANGLE SENSOR - An assembly includes a hoist or a winch, a cable, and a fleet angle sensor. The fleet angle sensor includes a frame disposed around an opening. A first photodetector with multiple light-receiving zones is mounted on the frame. A first light source is mounted on the frame opposite the first photodetector. The first light source directs a first light beam across the opening to the multiple light-receiving zones of the first photodetector. The cable extends through the opening and into the first light beam, and the multiple light-receiving zones produce signals that vary based upon a fleet angle of the cable extending through the opening. | 09-18-2014 |
| 20150097148 | WINCH DRUM - According to some embodiments, a winch apparatus comprises a winch housing and a winch drum rotationally mounted to the housing. The winch drum is configured to rotate around its central axis. The winch drum comprises a slotted keyhole for coupling a winch line to the winch drum. The slotted keyhole comprises an opening at a first end configured to receive the winch line positioned in the slotted keyhole and an opening at a second end configured to retain the winch line. A longitudinal axis of the slotted keyhole is offset from the direction the winch line pays onto the winch drum. | 04-09-2015 |
| 20150379783 | EMBEDDED HOIST HUMAN-MACHINE INTERFACE - A cable drum receives a length of working cable that is wound in and out from the drum in response to powered rotation of the drum with an uppermost layer of working cable on the drum forming a working surface. A torque sensor in communication with the cable drum measures a torque applied to the cable drum due to tension on the working cable from a load. A drum height gauge is provided for measuring a height of the working surface of the cable on the cable drum. A processor receives the torque value from the torque sensor and the height of the working surface from the drum height gauge and computes a force applied to the length of working cable due to the load based on the torque and height of the working surface. The work performed by the cable may be calculated to assist in determining cable health. | 12-31-2015 |
| 20160002013 | Tether Winding - Wind energy systems, such as an Airborne Wind Turbine (“AWT”), may be used to facilitate conversion of kinetic energy to electrical energy. An AWT may include an aerial vehicle that flies in a path, such as a substantially circular path, to convert kinetic wind energy to electrical energy. In an example embodiment, the aerial vehicle may be connected to a ground station via a tether that both restrains the AWT and conveys the electrical energy to the base station. The tether may be wound about a drum when the AWT is not in flight, and the drum may include a helical groove of varying pitch to receive the tether. An asymmetrical levelwind may be positioned adjacent to the drum and configured to move along the drum and guide the tether onto the drum. | 01-07-2016 |
