The Cable Pusher: Pushing Through the Trenches

The sturdy Cable Pusher (89760) is ideal for installing electrical cables in trenches or underground work. The Cable Pusher provides often needed mid-assisting support between the Cable Reel and the Winch. It is hydraulically driven and typically powered by a Power Pack (supplied separately) with an output of 4 gallons/minute and 1500 psi (max). The Power Pack (32799) features an integrated oil cooler, which is particularly important when working for long periods of time or in high temperature environments. The direction and speed of the Cable Pusher is controlled by a Control Valve with Hoses (89761) featuring a spring-centered valve. Continue reading “The Cable Pusher: Pushing Through the Trenches”

The D Umbrella for A+ Work

As the weather warms and the hot sun comes out, a D Umbrella (P/N 80920) is every outdoor worker’s saving grace.

Best in its Class: The Cable Pony Winch

The GMP Cable Pony is a hydraulic winch that often is regarded as the best winch produced by GMP. This universal winch is ideally suited to ADSS installations, but can be used in general aerial stringing work, conductor recovery and underground cable handling as well. In our ADSS installation blog, we discussed the use of the cable pony in ADSS installation. When installing ADSS cable, your team needs a winch that they can trust will provide optimal service throughout the job. Today, we’re taking a closer look at why the cable pony is one of the best winches on the market. Continue reading “Best in its Class: The Cable Pony Winch”

Microduct Overriding: Part 3

Microduct overriding has become an increasingly popular method to install new cable in an overly saturated area that may not allow for new ducts to be installed. While the process is not new, it’s incredibly important that your team uses the best possible equipment to get the job done right, avoiding any hiccups that could occur during installation.

Duct Rodders: The Best In The Business

Duct Rodders are a crucial piece of cabling equipment used for various purposes in underground installation. From cleaning ducts to locating paths, threading lines and pulling cables, the frequent use of a duct rodder often leaves it subject to wear and tear. This can complicate the job and even damage your conduit if operated incorrectly.

Sheaves, Shackles, and Jamb Skids: Equipment Needed for Underground Cable Installation

When pulling cable underground, an assortment of highly specific tools are needed in order to properly and efficiently feed cable into an existing duct. Below the manhole, a combination of sheaves, shackles, and jam skids are needed to effectively get the job done. In this blog, we’ll be explaining the necessary tools for underground cable placement, and providing a few examples of how they fit together.

Introduction to ADSS and the Tools Needed For Installation

ADSS is an acronym for All-dielectric Self-supporting Optical Cable. An alternative to OPGW and OPAC, ADSS cable is designed for aerial self-supporting application for short, medium and long span distances, up to 700 meters. ADSS cable is designed to be lightweight, small in diameter and fully dielectric construction. Utility companies often install ADSS cable along existing overhead transmission lines, sharing the same space as the electrical conductors to reduce costs.ADSS Pole1 ADSS Pole2 Continue reading “Introduction to ADSS and the Tools Needed For Installation”

Selecting the Correct Cable Lashing Wire 


From Boston, MA to Phoenix, AZ, lashing wire is used to connect all corners of the country. Stainless steel lashing wire is used in a lasher to bind an aerial cable or combination of cables to a supporting strand. In supporting telecommunications and electric cable, you could say that lashing wires literally bind America together. Continue reading “Selecting the Correct Cable Lashing Wire “

A Brief History of GMP

In 1936, a young engineer with an entrepreneurial spirit began a specialty machine shop in Philadelphia. Among his early clients was the Pitcairn Autogiro Company in Willow Grove. This young engineer was none other than George M. Pfundt, founder of General Machine Products, pictured here in Washington DC alongside the flying machine (AC-35 Autogyro) that used his precision machined parts.
