Greenlee is an American industrial and electrical tool company headquartered in Rockford, Illinois. It was founded in 1862 by twin brothers Robert L. and Ralph S. Greenlee to manufacture their invention, a drill surrounded by four chisel blades, used in making the pockets for a mortise and tenon joint, for the furniture industry in Rockford. [1] This device is still used in cabinetmaking. The brothers later diversified into a variety of hand woodworking tools as well as machinery for making wooden barrels.
The company was acquired by Detroit-based Ex-Cell-O in 1969. [1] Industrial conglomerate Textron acquired Greenlee as part of its acquisition of Ex-Cell-O and its subsidiaries in 1986. [2] Greenlee purchased Fairmont Hydraulics in 1992 and German tool manufacturer Klauke in 1996. Greenlee expanded into data/telecommunications equipment with the acquisition of several companies in 1999 and 2000 which now fall under the Greenlee Communications brand. Greenlee expanded its DIY offering with the addition of Paladin Tools on December 17, 2007. In 2008, Greenlee acquired Utilux. [3] [4] In 2013, Sherman + Reilly, and HD Electric joined the Greenlee family of Utility brands. The Greenlee brothers were inspired into industrial work by their father who was a cooper. Their contributions to the railroad industry included an automatic tie and track laying and drilling machine that rolled right along behind on the track it had just laid.
On April 18, 2018, Textron announced that it planned to sell its Greenlee brand to Emerson within 90 days. [5] Greenlee is listed as a subsidiary and/or affiliate of Emerson Electric Co. as of September 30, 2019. [6]
Cessna is an American brand of general aviation aircraft owned by Textron Aviation since 2014, headquartered in Wichita, Kansas. Originally, it was a brand of the Cessna Aircraft Company, an American general aviation aircraft manufacturing corporation also headquartered in Wichita. The company produced small, piston-powered aircraft, as well as business jets. For much of the mid-to-late 20th century, Cessna was one of the highest-volume and most diverse producers of general aviation aircraft in the world. It was founded in 1927 by Clyde Cessna and Victor Roos and was purchased by General Dynamics in 1985, then by Textron, Inc. in 1992. In March 2014, when Textron purchased the Beechcraft and Hawker Aircraft corporations, Cessna ceased operations as a subsidiary company, and joined the others as one of the three distinct brands produced by Textron Aviation.
An electrician is a tradesperson specializing in electrical wiring of buildings, transmission lines, stationary machines, and related equipment. Electricians may be employed in the installation of new electrical components or the maintenance and repair of existing electrical infrastructure. Electricians may also specialize in wiring ships, airplanes, and other mobile platforms, as well as data and cable lines.
In the oil and gas industry, the term wireline usually refers to the use of multi-conductor, single conductor or slickline cable, or "wireline", as a conveyance for the acquisition of subsurface petrophysical and geophysical data and the delivery of well construction services such as pipe recovery, perforating, plug setting and well cleaning and fishing. The subsurface geophysical and petrophysical information results in the description and analysis of subsurface geology, reservoir properties and production characteristics.
Excavators are heavy construction equipment consisting of a boom, dipper, bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels, as power shovels may have similar looking buckets. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators, which use winches and steel ropes to accomplish the movements.

Well logging, also known as borehole logging is the practice of making a detailed record of the geologic formations penetrated by a borehole. The log may be based either on visual inspection of samples brought to the surface or on physical measurements made by instruments lowered into the hole. Some types of geophysical well logs can be done during any phase of a well's history: drilling, completing, producing, or abandoning. Well logging is performed in boreholes drilled for the oil and gas, groundwater, mineral and geothermal exploration, as well as part of environmental and geotechnical studies.

Emerson has approximately 86,700 employees and 170 manufacturing locations.
A load cell converts a force such as tension, compression, pressure, or torque into a signal that can be measured and standardized. It is a force transducer. As the force applied to the load cell increases, the signal changes proportionally. The most common types of load cells are pneumatic, hydraulic, and strain gauge types for industrial applications. Typical non-electronic bathroom scales are a widespread example of a mechanical displacement indicator where the applied weight (force) is indicated by measuring the deflection of springs supporting the load platform, technically a "load cell".
NOV Inc., formerly National Oilwell Varco, is an American multinational corporation based in Houston, Texas.

Slickline refers to a single strand wire which is used to run a variety of tools down into the wellbore for several purposes. It is used during well drilling operations in the oil and gas industry. In general, it can also describe a niche of the industry that involves using a slickline truck or doing a slickline job. Slickline looks like a long, smooth, unbraided wire, often shiny, silver/chrome in appearance. It comes in varying lengths, according to the depth of wells in the area it is used up to 35,000 feet in length. It is used to lower and raise downhole tools used in oil and gas well maintenance to the appropriate depth of the drilled well.
