  • Publication number: 20240010469
    Abstract: A piling head puller device comprises an elongated cylindrical rod having drive head at a proximal end thereof, an upper section having smooth outer surface portion between the drive head and a stop flange, and a lower section having a threaded outer surface portion rom the stop flange to the distal end. The piling head puller device includes a swiveling lifting element having a pull ring and a bearing washer, which defines a glide hole through which the elongated cylindrical rod extends and moves axially freely between the drive head and the stop flange, such that the pull ring is positionable at an angle to avoid obstruction with the elongated cylindrical rod. Rotation of the drive head removably embeds the threaded outer surface portion into a wooden piling head. A hoist can pull the lifting element which bears on the drive head to remove the wooden piling from the ground.

  • Publication number: 20240002134
    Abstract: An electrical wire compression connector dispensing container device for individually dispensing single compression connectors comprises a housing defining a connector dispenser opening and a torsional spring operatively connected to a spring biased vertically movable horizontal platform for holding the compression connectors, allowing the platform to move upwards when the top compression connector is removed. The container can store a plurality of connectors with the top connector positioned in a dispenser opening. A bottom of the container has a weep hole for drainage of rainwater, and a back of the container has clamps providing a removable connection to a man-lift basket. A user can efficiently store and dispense a compression connector from the opening, and the torsional spring expands upwardly thereby pushing the next compression connector to a top row to be dispensed.
