Certain exemplary embodiments can provide a system comprising a frame, which comprises an outer mast and an inner mast. The outer mast slides along the inner mast. A motor is coupled to the frame. A hydraulic system is coupled to the motor. A jackhammer head is coupled to the outer mast, which outer mast allows the jackhammer head to float up and down on the inner mast as the jackhammer head reciprocates. Thereby vibrations from jackhammer motion substantially do not get transferred to the frame.

Various embodiments of cable railing systems are disclosed. Although not limited to these applications, the embodiments are particularly useful in connection with cable railing systems with hollow metal support members or with solid concrete support members with weld plates. The embodiments include straight and corner cable termination assemblies that are designed to support a metal cable railing, particularly one that is heavy gauge.

An apparatus and method for clipping a fence wire on a T-post.

A method is provided for using a collar to either drive a post into the ground or remove a post from the ground. The method includes, when driving a post into the ground, coupling the collar to the post in a first orientation so that a post opening of a first portion of the collar extends about the post, and applying a driving force to a second portion of the collar. The method also includes, when removing a post from the ground, coupling the collar to the post in a second orientation, rotated approximately 180 degrees from the first orientation, so that the post opening of the first portion of the collar extends about the post, and applying an extracting force to the second portion of the collar.

A fence installation system for automating the fence installation process includes a trailer apparatus. A post dispenser apparatus is configured to secure a plurality of fence posts. A post holder apparatus comprises a first robotic arm and a claw configured to secure a fence post. A post hole drill apparatus is coupled to the trailer apparatus and comprises a second robotic arm, a drill head, and an auger bit. A post driver apparatus comprises a third robotic arm and a driver head configured to drive the fence post into the ground. A fence wiring apparatus comprises a spool axle and a plurality of wire spools coupled to the spool axle. A control apparatus is in operational communication with each of the post holder apparatus, the post hole drill apparatus, the post driver apparatus, and the fence wiring apparatus.

A razor wire rapid deployment unit (RDU)/barrier is disclosed. In some embodiments, the RDU includes an enclosure having a first section coupleable with a second section, the enclosure defining an interior area therein. The RDU may further include a razor wire disposed within the interior area of the enclosure, a first end of the razor wire directly coupled to the first section, and a second end of the razor wire directly coupled to the second section. The first and second sides of the enclosure may be separated from one another to deploy the razor wire from a compressed configuration to an expanded configuration.
