Based in Gipuzkoa, Spain, Topac manufactures pneumatic hammers for the mining, construction, quarry and other industrial sectors. The product range includes pick hammers, mini pick hammers, rock drill hammers and concrete breakers, as well as related tools and accessories.

\n\n

Topac is the brand of the pneumatic hammers division of Elcoro Decoletaje, a Spanish industrial group founded in 1892. All Topac hammers are manufactured at the Gipuzkoa facility and comply with European CE standards.

\n\n

According to Topac, its hammers are exported to numerous markets such as Colombia, Brazil, Cuba, Costa Rica, Ecuador, Guatemala, Mexico, Peru, Uruguay, as well as Europe, North Africa, Indonesia and the Philippines. The brand is currently present in 25 countries and continues to expand its distribution network globally.

\n\n

Topac hammers feature a functional and ergonomic design, with a reduced number of parts and an air chamber system. They require no in-line lubrication, except for the drill hammers.

\n\n

The pick hammers, with weights of 5.5 kg and 8 kg, are lightweight and small in size. They are suitable for use in mining, construction of tunnels, demolition of concrete, and more.

\n\n

The mini pick hammers weigh only 5 kg and offer low air consumption. Designed for ease of operation, they are excellent for construction, mining, rehabilitation and other industrial applications.

\n\n

The concrete breakers comprise two models. The T-275 with a weight of 30 kg is well suited for heavy demolition works. Its exclusive ‘air chamber’ system allows users to overcome the vibration tests without additional tools, like antivibration handles. Meanwhile, the T-103 has a weight of 10.5 kg and is ideal for light demolition works.

\n\n

The rock drill hammers, weighing 17 kg and 25 kg, are specially designed for high speed drilling. They feature low air consumption and can be supplied with a water jet. The air-line lubricator T-5000 should always be used to ensure a proper running, efficiency and long life of these drill hammers.

\n\n

All Topac hammers have a pressure of between 5 bar and 7 bar. They provide reduced maintenance costs due to less wear and tear on parts. This also makes them highly durable.

\n\n

Cat GC-series hydraulic hammers have been expanded to include the H160GC and H180GC models, in addition to the existing H110GC, H115GC, H120GC, H130GC and H140GC. They are designed for high production in a wide range of demanding applications – such as quarry, road construction, demolition and general construction – while keeping the user’s owning and operating costs at a minimum.

\n\n

The GC-series has a simple design that ensures reliability, long-term durability, ease of use and ease of maintenance. Ideal for hydraulic excavator carriers weighing 11 to 52 t, each hammer is tested per the ISO quality control system before customer delivery to guarantee optimum quality.

\n\n

Whilst the H110GC, H115GC, H120GC, H130GC and H140GC have the same features, the H160GC and H180GC come with additional features of standard automatic shut-off and auto lube option. Major components of the hammers (cylinder, back head, front head, piston and tool) are manufactured with high-quality materials and processes.

\n\n

The housings are fitted with bottom reinforcement plates that protect against breakage and wear. The high-pressure accumulator is field-serviceable, protects the carrier’s hydraulic system by absorbing pulsation spikes created during the firing stroke, and is also sized to provide optimum breaking power and to absorb piston-recoil shock for improved tie-rod life.

\n\n

The long piston transfers long shock wave into material. The piston diameters are matched for maximum energy transfer, and the piston’s design and surface finish provide superior oil retention and seal life.

\n\n

The oil-control valve is the outer type, allowing easy setting, reduced pulsation and low maintenance costs. The side rod (though bolt) is specially heat treated for durability, and the side-rod nut is protected from thread damage.

\n\n

The stroke-control valve allows adjusting for primary or secondary breaking chores and for breaking different material hardness more effectively .

\n\n

Additionally, the full-length side plate enables easy access to service points, including tool and bushings, with the lower tool-bushing replaceable in the field. Easily accessible pressure check point allows quick monitoring of the hammer’s operating condition.

\n\n

Tool-type options for the hammers include moil, pyramidal, chisel and blunt. This selection allows effectively adapting the hammer to an extensive range of applications, which might include secondary breaking of blasted rock in quarries and mines, trenching in tunnels, breaking refractory linings in steel-making furnaces, concrete demolition, rock excavation for foundations, breaking frozen ground, and separating rebar from concrete for recycling.

\n\n

The design, features and construction of the GC-series hammers combine to deliver optimum life-cycle value for the user’s investment. All units are available with Cat standard warranty (one year unlimited hours) and Cat dealer support.

Two lightweights in the Indeco small hammer range - the HP 400 FS and HP 550 FS - have been upgraded with more powerful features. Starting with energy class, it rises to 550 joule for the HP 400 FS and 750 joule for the HP 550 FS. The hammers’ blows per minute also increase to 540 -1,670 and 780-1,720 respectively, as well as their tool diameter (65 mm and 75 mm respectively) - which is an increase of approximately 10 mm for both.

\n\n

This improvement has not changed the hammer size and design in either model, said Indeco. The units are ideal for use with excavators between 2.5 and 5 t for the HP 400 FS, and 3.5 - 6.5 t for the HP 550 FS.

\n\n

In addition, the larger Indeco HP 6000 FS hammer takes up a position midway between the HP 5000 and HP 7000. With a working weight of 3,600 kg, energy class of 9,000 joule, and a steel diameter of 170 mm, this model is an ideal fit for excavators in the 35 - 45 t range, especially given its excellent power-to-weight ratio. According to Indeco, the HP 6000 FS also features Hardox inserts in the lower part of the casing, which enable it to withstand even the toughest jobs.
