Premium Quality Cable Lashing Machines

GMP is perhaps best known for its line of premium quality cable lashing machines, sometimes called simply “lashers” or “spinners” that wind stainless steel wire around telephone, power, and multi-media cable thereby securing or “lashing” it to the supporting messenger strand between poles. In the 1940’s, the company pioneered the modern automatic lashing machine with Bell Telephone Laboratories, establishing the telephone industry standard in lashing technology. Since then, GMP has produced over 30,000 lashing machines. Some that were manufactured in the 1950’s are still at work today. Five lashing machine models make up the company’s current product line, which covers every type and size of cable.

Fiber Optic Blowing Machines and Trailer Mounted Fiber Pullers

In 2004 GMP acquired CBS Products in England, UK. CBS and GMP manufacture a full line of cable blowing (or cable jetting) machines both domestically and in the UK., for placing fiber optic cables, micro tubes and blown fibers in FTTx. In addition, CBS manufactures winches, pullers and tensioners for electrical transmission and distribution lines and railway trackside cabling.

The Adams® Continuous Duty Winches

GMP’s Adams Continuous Duty Winches are another of GMP’s most recognizable lines. The first Adams winch was conceived in the 1950’s through the combined efforts of engineer Frank Adams and, once again, the Bell Telephone Laboratories. The resulting winch specifications became the accepted standard within the North American telephone industry. In 1973, GMP acquired ownership of the Adams Engineering winch designs, and has continued to add practical design enhancements to the Adams Winch product line.

Our Facilities

GMP’s 100,000-square-foot manufacturing plant in Trevose is equipped with a full complement of technologically advanced machine tools manned by a well-trained team of craftspeople. Our own engineering staff conducts research & development of GMP’s products using 3D solid modeling design and manufacturing, a prototype fabrication shop and an on-site testing facility.
