Antraquip Corporation

Antraquip Corporation is a leading global supplier of roadheaders, hydraulic rock cutting attachments for excavators, reliable tunnel support systems and auxilary products for the tunneling, mining and construction industries.

With over 30 years of experience in mechanized rock cutting methods and its continuous research and development, Antraquip can offer the most innovative, reliable and efficient solutions for your projects with the use of roadheaders or hydraulic excavator attachments.

In addition to a state of the art production line, Antraquip also offers engineering and consulting services including equipment refurbishment and rebuilds. 

New AQM Road Headers

Antraquip roadheaders are advanced, self-propelled, extremely powerful rock-cutting machines designed to excavate roadways, tunnels and chambers continuously without using explosives. Powered electro-hydraulically, they emit no fumes and are used extensively in coal mining, mineral mining and underground construction projects, where their ability to excavate the desired profile without causing harmful vibrations is highly valued for both environmental and safety reasons.

For more technical information about the above machines, please contact us at 301-665-1165 or email sales@antraquip.net

Hydraulic Rock / Concrete Cutting Attachments

Antraquip's line of rock cutting attachments are designed to be mounted on suitable excavators ranging from 2 to 110 tons to be used an various rugged mining, tunneling and general construction applications.

We provide two types of cutter head designs, the transverse design and the lengthways (uniaxial) design to ensure the ideal fit for any given application. The AQ line of cutters are engineered and equipped with a high torque low speed hydraulic motor with rugged gearing and symmetrically aligned cutter bit patterns on the cutter head that enables the machines to be extremely efficient not only in specialty applications but also in hard rock excavation often outperforming hydraulic hammers.

Some of the most common applications for these Antraquip cutting attachments include trenching, tunneling, scaling, production mining, underwater cutting, demolition and profiling. Please see some sample pictures and videos of our AQ cutters being used for various projects by visiting the photo and video galleries.

Specifications & Model Selection
In selecting the proper Antraquip attachment for your excavator/carrier, it is critical that the hydraulic system requirements are met as noted in the specs below. Please note that at least 1/3 of the total oil flow available will be needed to operate the excavator.

Technical Data for Transverse Cutters

Antraquip Transverse (double drum) cutters are designed to for many rock and concrete cutting applications including trenching, scaling, foundation work, tunneling, mass excavation, mining, profiling, rock dredging, soil remediation, demolition and many other types of specialized excavation projects. 

Technical Data for Lengthways Cutters

Antraquip Lengthways (uni-axial) cutters are designed for specialty rock and concrete cutting applications such as narrow trench excavation, concrete removal, tunnel profiling etc. For more information and assistance with model selection please contact us at 301-665-1165 or info@antraquip.net.

Rebuilt / Reconditioned Road Headers

Antraquip rebuilt/reconditioned roadheaders offer efficient, reliable and creative solutions at reasonable prices. Similar to new roadheaders, Antraquip’s rebuilt/reconditioned roadheaders are ideal for the mining of potash, uranium, salt, coal, gypsum, phosphate, talc, gold and for tunneling projects including road, sewer, railroad, and water tunnels.

Rebuilt and reconditioned models are available for sale or lease

Lattice Girders

Pantex Lattice Girders have been developed for the special demands of tunnel construction. This system has been rigorously tested and successfully installed in many tunnel projects throughout the world. Contrary to standard rolled steel sections and regardless of shape the Pantex Lattice System in conjunction with shotcrete, is totally surrounded by concrete, forming a complete homogenous composite structure with no unconsolidated areas, voids or fissures visible. The overall result is a tunnel lining that significantly reduces ground settlement and prevents the ingress of water.

AQ Arch Canopy System

Antraquip’s Arch Canopy (Barrel Vault) System is designed for pipe roofing, forepoling, anchoring and drainage.

For underground infrastructure building in typical urban areas, poor ground conditions and for all underground construction in weak and disturbed soils modern tunneling engineers have developed a face stabilization and protection system called “Tube Umbrella” or “Forepoling”. The method is based on the use of drilled piped (tubes) in the advance of the tunnel face. Antraquip is leading the way in offering complete systems which include all components needed for forepoling and roof piping applications wherever dripping is required.
