  • Patent number: 11858028
    Abstract: A method of bending a conduit is disclosed. An engagement member is displaced via contact with the conduit and engages a switch. A signal is sent to a microprocessor indicative of a characteristic of the conduit to be bent, in response to engagement of the switch. The microprocessor provides a motor control signal to the motor to control a rotation of the shoe, wherein rotation of the shoe bends the conduit.

  • Patent number: 11400503
    Abstract: A conduit bender having a unitary frame is mounted to a wheeled base which provides for transportation of the bender. A braking assembly provides for simplified locking of the wheels to secure the bender in a location. The bender is mounted to the base through a pivoting assembly which allows for bending of conduit in either a horizontal or vertical plane. A circuit is provided for controlling the bending operation. An auto-sensing portion of the circuit receives information regarding the characteristics of the conduit to be bent upon placement of the conduit in the bender. A feedback portion of the circuit is used to provide a precise bending operation.

  • Patent number: 8651459
    Abstract: A device for dispensing fish tape includes a pair of outside walls and outer and inner annular walls depending generally perpendicularly from the edges of the outside walls. Intermediate pinch ring walls depend generally perpendicularly from the outside walls and are positioned between the inner and outer walls. A plurality of spaced apart protuberances are provided on the intermediate walls and engage undulations on a hoop of a winding belt mounted within the device. A fish tape is mounted within the device and engages with the winding hoop. Each outside wall has a flat section extending from the outer edge thereof toward the inner edge thereof, and a raised section extending from the flat section to the inner edge.

  • Patent number: 8302936
    Abstract: A cable puller assembly includes a housing assembly, a motor assembly and an anti-fouling device. The motor assembly is secured to the housing assembly and has an output shaft extending outwardly therefrom. The output shaft is rotated about an axis of rotation by the motor assembly. The anti-fouling device has a capstan and a body. The output shaft is operatively associated with the capstan in order to rotate the capstan about the axis of rotation. The body is positioned around an end portion of the capstan proximate to the housing assembly. The body defines a sloped surface that biases incoming rope that wraps around the sloped surface down onto the capstan.

  • Patent number: 8246009
    Abstract: A puller head and cable puller including the puller head are provided for pulling cable in an upward or a downward direction. The puller head includes a frame, a capstan mounted to the frame, and first and second retaining shaft apertures. The puller head is pivotally mounted to a boom of the cable puller through a pivot shaft. The capstan of the puller head is positioned rearward of the boom. The position of an upper most surface of the capstan relative to the boom is changed by pivoting the puller head between upward and downward pulling positions. The puller head is maintained in either the upward or downward pulling position through the use of a retaining shaft.

  • Patent number: 7926788
    Abstract: An attachment system for a cable puller provides for securing the cable puller to various sized conduits. The attachment system includes a clamping assembly having pivotable arms angled to generally be formed in V-shapes at the ends which engage and trap the conduit at four separate points. The clamping arms have gripping members that radially nest against the conduit threads and an overhang portion which acts as a location stop for the conduit. Each clamping arm has a face which extends past the pivot point. A screw and a nut between the extended portion of the clamping arms act on a push block which in turn acts against the arm faces such that when the nut is screwed inward, it causes the gripping members to be forced against the conduit in order to secure the conduit in place.
