HAC System for Tunneling Ideal for both mining and industrial applications, including handling of wet or sticky materials May be shortened or lengthened or have the conveying angle altered for a new location.Partial-face Excavation Machines made by Herrenknecht are an economically interesting solution in homogeneous and almost stable grounds with little or no groundwater.
This tunnelling technology can be easily adapted to changing geological conditions both in loose soils and in hard rock due to its strikingly simple design. Partial-face Excavation Machines are equipped with excavators or roadheaders depending on the project's geology. Herrenknecht shields with partial-face excavation can excavate the soil with two different cutting tools. In loose soils, the excavator has proved its great value hundreds of times.
The universal excavator boom is equipped with a shovel, a ripper tooth or a hydraulic jackhammer — depending on the soil conditions. Roadheader booms are used in harder rock with uniaxial compressive strengths of up to 80 megapascal. Both boom technologies allow quick and easy replacement of the worn tools.
The excavated material is transported by belt conveyors or chain conveyors to the conveying system in the back. The application range of Partial-face Excavation Machines starts at around 2 meters, as it is necessary to access the tunnel. Tunnelling operations with diameters of more than 10 meters can be carried out cost effectively using additional support measures or grout injections to improve the ground. The rim of the shield is extended in the crown section to reduce the repose angle in incohesive geologies.
Are advanced from the launch shaft and transfer the thrust forces from the jacking frame to the machine. One advantage of Partial-face Excavation Machines is that the workplace of the operator is just a few meters away from the open tunnel face. This makes it possible to control excavation precisely, react swiftly to changes in the ground and take appropriate measures if necessary. One example is the excavation and removal of large boulders or obstructions without having to create additional shafts.
Direct visual contact with the geology is also an advantage for the steering process. In pipe jacking, the machine is controlled using steering cylinders and an articulation joint in the front section of the shield.
With larger diameters and during segmental lining, the machine is steered via the main thrust cylinders in the same way as closed-shield machines. Safe in hard rock.Extremely powerful for its compact size, our tunnelling excavator with short boom and arm can be fitted with attachments that are suitable for larger tonne machines, including crushers and breakers.
It can easily be lowered into position on sites below ground level using a crane, and works well in tandem with excavators using clamshell telescopic arms.

Fleet management — Global e-Service.A Cooler Tunnel is more of a continuous cooling mechanism where the hot product is placed onto an endless traveling band or porous belt and is conveyed through the cooling box which has recirculating air blowing through the product. Upon exiting the belt the product is cooled to the requisite temperature and possible moisture.
Frain is fully staffed with engineers and technicians who can completely integrate cooling tunnel machines, retrofitting or reconditioning each machine to meet your exact specifications. We include in-house testing with every machine that ships, proof of concept and trial runs.
