The common goal for ourcustomers - more tonnesper hour with less cost is alsobehind the Brøyt concept.A unique face shovel design combined withpowerful hydraulics is the key to a full bucket andfast work cycles.Robust steel structure, modern engines and provenhydraulic system have been designed for loadingtasks in hard rock applications. Tunnel projects,room and pillar type mining operations, quarriesand dam projects are ideal job sites to utilizeBrøyt's high loading capacity. Often simple ideasare the best - for example Brøyt wheel model -it can be towed fast from loading face to another.This way one wheel type machine can handleloading tasks in large area.Brøyt products are tough. Their design is unique and far from conventional,resulting in a digging ability that places them in a class of their own.All Brøyt machines have a unique boom geometry and hydraulic cylinder configuration providinga fast and effective penetration, breakout and liftsequence. As the bucket filling action engages therock pile, the reaction forces "press" the machine harder against the ground. The major advantageof this feature is that the harder the dig the greater the reaction resulting in more stable andproductive machine. Applied correctly Brøyt face shovels will not push back from the rock face.Another major benefitis lighter counterweight requirementresulting in higher capacity andexcellent fuel economy.Brøyt's hydraulic control system delivers forceand speed according to the load demand during theproduction cycle. The operator retains smooth and precisecontrol over his machine.

Superior production capacity- unique boom geometry and hydraulic cylinder configuration- high efficiency load sensing hydraulicsCost effective production- low power/ fuel consumption due to effective digging characteristics- use of gravity instead of engine power when dumping and boom lowering- less stress on undercarriage due to unique boom geometryFlexibility of operation- compact design for working in limited spaces- diesel or hybrid (electro diesel) power options- heavy duty tracked or steel wheel (no drive) undercarriage options- quick hitch system for scaling tool, hydraulic hammer or cutting headFull support by Broyt and SandvikTamrock organization- worldwide service and parts network- in depth application knowledge- capacity to offer the best solutions

Underground applications - Compact PowerThe Brøyt concept reduces the production cycle times considerably in mostunderground excavation applications. It's unique and compact boomconfiguration places Brøyt as the only dedicated face shovel which can workboth effectively and efficiently in typical highway and railway tunnels.In tunneling the electro diesel - ED - machines offer unmatched digging solution and exhaustfree environment. The outstanding loading capacity provide fast and efficient face cleaning andloading into hauling trucks, feed hopper or mobile crusher. The quick coupling system enablesrapid change of bucket, scaling tool, hydraulic breaker or cutting head. In many tunnel projectsBrøyt can save considerably time when loading and scaling can be done with the same unit.Todays safety requirements and zero tolerance to accidents can be met by using Brøyt - switchingeconomically from loading to scaling as often as needed.Brøyt enables you to meet your tunneling scheduleand improve your contract profitability.Fast loading cycle• reduced excavation time• more tunnel advance• faster tunnelling process• improved mining process and mine outputLow operating cost• lower excavation cost per tunnel meter• low energy cost with electric drive• reduced ventilation capacity requirement• clean-up, scaling, hammering with the same machine - low capital cost• improved contract profitabilityFull control of working environment• no exhaust emissions with electric drive• low noise level• dust suppression system (option)

Surface applications - Stable PowerDedicated face shovel design makes Brøyt unbeatable in quarry operations.Brøyt's loading power has been accomplished with unique and well provenboom and hydraulic design. Machine's capacity versus own weight is on it'sown level. Less mass and less fuel is needed to load more tonnes.Operations with many loading faces can relocate wheel type Brøyt very fast with dumptruck. This enables flexible production planning and cost savings compared to machines withtrack type undercarriage. Wheel type Brøyt can be easily moved between working faces andservice area enabeling maintenance in good working conditions.The Brøyt design guarantees that the machine remains stable and in total command at thequarry face. Brøyt machines will not push back when penetrating and filling the bucket, thusallowing 100% utilization of available digging forces.Fast bucket filling and discharge combined with short swing time provide hightruck loading capacity. Handling of oversize and quarry floor maintenance ismade easy.The Brøyt range of equipment and specialized service support help you to speed upquarry production, increase equipment fleet utilization and improve the total profitabilityof your minerals process.High equipment utilization• fast loading of hauling fleet• efficient handling of oversize• simultaneous quarry floor maintenanceImproved production process• efficient handling of shot, even poorly fragmented rock• minimized non-loading time by loading directly from quarry floor• uninterrupted quarry process with Sandvik Tamrock service supportLow production cost• Brøyt loading technique, low resistance hydraulic system andlow machine weight resulting in good fuel economy• robust frame and boom structure, undercarriage and bucket

Unmatched VersatilityVarying applications demand something special from a machine.In tunnelling projects the use of robust scaling tool increases safetyand saves time when truck waiting time can be used for scaling.The world renowned wheeled system provides rapid relocation,simple transportation and drastically reduced undercarriagemaintenance cost.Brøyt offers a choice of undercarriage to suit different operating environments,heavy duty tracked undercarriage or extremely reliable and simple steel wheelversion without drive.Covers of the upper body in the openposition form a sturdy working platformwith easy access for daily service andmaintenance.The quick coupling system enables fast interchange of bucket and tools.Hydraulic hammers can be quickly attachedfor reducing oversize in addition to otherbreaking applications including primarybreaking intunnelling or quarrying.
