The Hymac Company established 1946, pioneer of the all hydraulic 360 excavator, located at the Rhynmey Engineering plant in Wales, manufacturing machinery, and assembling the Hy-Hoe Excavator from the Hydraulic Machinery Company of America. Hy-mac UK then went on to design and manufacture its own hydraulic excavators and became a world leader in manufacturing a wide range of Hydraulic construction machinery. 1972 Hymac take over Whitlock Bros. the backhoe loader manufacturer est in 1899. The Hymac all hydraulic tracked excavators, (A Worlds First) and Hymac 370 wheeled backhoe loader range being the brand leaders. Hymac also designed and manufactured the Hymac Jupitor 1050 all hydraulic crane,first in the world.
The "Hymac" brand name has been used in several variations over the years (Lower case, all caps and hyphenated versions) in the companies own marketing material and the livery/ decals on the machines.
- HY-MAC/HYMAC/Hymac being the most common variations.
HY-MAC was the US Registered Trade Mark of the Hydraulic Machinery Company America. The actual UK company HYMAC LIMITED dates back to 1946. The HY-MAC trade Mark was assigned to HYMAC LIMITED in 1972.
The companies history like many other UK manufacturing firms has been complicated by the ups and downs of the economy and construction industry. This has resulted in many take overs and mergers with the brand being the 'public' face of the company and various corporate entities having control and marketing a variety of machines as HY-MAC, HYMAC and Hymac . Some of these machines were designed and built by them and some manufactured under License from other firms and also some just badge engineering of machines built by others, as is the case with a lot of brands today like Massey Ferguson who are now a brand and a subsidiary of AGCO with some items built by other companies in the group or external suppliers.
Peter Hamilton Equipment Ltd started to import the American designed and built Hy-Hoe excavators in kit form. These were assembled at a factory in Rowesley Derbyshire. When HY-MAC America ceased manufacture in 1962 Hymac then took on the manufacturing rights, and Rymney Engineering stared manufacturing machines in South Wales, UK. The original Hy-Hoe design was not a 360 degree excavator but was limited to about 270 degrees as the slewing mechanism was chain driven.(see photo)
The Hymac 580B was replaced by the Hymac 580BT (Better Tracks) and eventually by the Hymac 580C.[when?] A more complete range of Imperial excavators was introduced including Hynac 880 and the Hynac 1280 which had capacities of 1 cu yd and 1.5 cu yd respectively.
To complement the tracked excavators a series of 4X4 wheeled equivalents were produced - the Hymac 610 being the 580 equivalent.
As part of the Powell Duffryn Group the Rhymney Engineering Company change it's name to reflect the Product name to Hy Mac.[citation (source) needed] Powell Duffryn were a mini engineering conglomerate at the time with interests from coal to transport and shipping. The company having a long history in coal and shipping, which still continues today. Powell Duffryn also owned other British Engineering firms such as Belliss and Morcom and Hamworthy Engineering, as well as the US-based Air Compressor Products Inc. and Eagle Compresors Inc., manufacturers of Industrial compressors.
During the Powell Duffryn era, they built a 180 wheeled Backhoe Loader during the 1970s that had a heavy duty loader more like a loading shovel with arms made of solid steel 1½ thick rather than box beams.[clarification needed] Some versions having High reach arms. These large machines had a flat deck cab, with good visibility from the raised position of the driver. This was based on the Whitlock 860 machine, Hymac having taken over Whitlock in 1972, a manufacturer of the Backhoe Loaders from 1952.
They also built a lot of wheeled 360 machines for scrap handling, fitted with 5 tine grabs or scrap magnets, often with raised cabs. Till scrap yards started being forced to modernise (cleaned up) under environmental rules introduced in the last few years, you would mainly see a Hymac or Atlas machine, or an old 22 RB crane in most yards. Now modern Terex built Fuchs and German Liebherr machines are predominant in the waste recycling industry. A few Caterpillar Inc. and Case material handlers are also about.
In the late 1980s a revised line of excavators with a new yellow colour scheme was launched. But too late to save them from the Japanese and other far eastern imports and their new (Japanese designed) line up.
The Hymac operation was sold to the German IBH Group in about 1980.
|dates are uncertain with conflicting reports - See talk:Hymac|
The IBH group was a German investment company that owned numerous engineering firms. IBH also owned the German firm Hanomag, but they went bankrupt in 1983 , when the bank that backed them got into difficulties. Hanomag was also linked with Massey Ferguson for a period, and built some of their construction plant models. Hanomag was partially taken over by Komatsu in 1989, with them becoming a 100% owned subsidiary of the Japanese firm in 2002. IBH also owned Euclid after it was divested by General Motors, but after IBH's collapse it reverted to GM till it was sold off and became part of Terex.
By the early 80's the Hymac excavator range consisted of four basic models; crawler Hymac 580D/DS, the crawler 450E/ELC and its wheeled versions [[Hymac W450E|W450E + W350D, the crawler Hymac 201LC and its wheeled version Hymac W201 which were introduced in 1983 these were designed jointly by Hymac & Hanomag, prior to the IBH collapse in 1983.
In 1984 Hymac was bought from the receivers by Northern Engineering Industries (NEI). Production of some Hymac models restarted near Wolverhampton. Then in 1987 the BM Group bought the company and renamed it Hymac Group Ltd. Then in 1988 ownership changed again after Gordon Brown (entrepreneur not British politician) (owner of Brown Anglo Scan Group) formed "Brown Engineering (Hymac) Ltd". They then to cut costs and offer more modern machines by selling badged Italian built machines from FAI Group. These were the Hymac W121 a 13 ton machine, Hymac 211 a 21 ton class model, and the Hymac 251 a 25 ton class machine.
Following the collapse of the Brown Group in 1991, Irish plant dealer John Kennedy then introduced some new models; the Hymac Synchron 1301 & Synchron 1501 in 1992 which featured Linde's Synchron load sensing hydraulic systems. But production of Hymac machines finally ceased in 1993.[citation (source) needed]
The very last machine ever built by Hymac was an model 181B 18t a sad end to yet another great British Engineering company. The Hymac name remains an iconic British Brand and many Hymac Machines remain in service around the world.[citation (source) needed]

A number of company's have and some still do a service to refurbish these machines as a number of users like the simplicity of a machine without the complex electronics of modern machines, for use in occasional light use application or modified as tool carriers for drilling rig used for grouting mine workings or with extra wide tracks on peat extraction duties.
The Machinery Forums report sighting of a number still in use around the world. They were a popular machine in scrap yards along with Atlas, but as the industry modernizes and consolidates to a few bigger operators the old yards are closing and new 'recycling centres' are being equipped with modern Caterpillar, Fuchs, JCB, and Liebherr material handling machines with long reach booms, high lift cabs and rotator grabs in-place of the old magnet on a chain.
Recently several machines have been refurbished in the UK for continued commercial service in scrap yards and as piling hammer bases.
