Long Reach Boom & Arm For A Mining Excavator
In the challenging world of mining operations, having the right equipment can make all the difference between project success and costly delays. The excavators long reach boom stands out as a game-changing attachment that transforms standard excavators into specialized machines capable of reaching extraordinary depths and distances. At Tiannuo Machinery, we've perfected manufacturing these essential mining tools, offering quality and performance in our extended boom and arm assemblies. With operating distances of up to 18 meters and compatibility with 20-25 ton excavators, our long reach systems enable mining professionals to access previously unreachable areas without compromising on stability or precision. Whether you're managing overburden removal, working on deep pit extraction, or handling material in hard-to-reach locations, a properly engineered long reach boom and arm combination provides the extended capabilities mining operations demand for enhanced productivity and safety while reducing equipment transportation needs across expansive sites.
Technical Specifications & Performance
Structural Engineering Excellence
The heart of any excavators long reach boom lies in its structural integrity. Tiannuo's long reach boom and arm assemblies are manufactured using high-tensile steel that balances strength with weight considerations. Our engineering team employs advanced stress analysis techniques to reinforce critical stress points while keeping the overall weight optimized. This meticulous approach prevents premature fatigue failure while ensuring the boom remains maneuverable.
The boom features a multi-section design with precise pin joints that maintain alignment even under heavy loads. We've incorporated specialized bushings at all pivot points that extend service intervals and reduce maintenance requirements. The hydraulic cylinder mounting points are reinforced with additional gusseting to handle the increased leverage forces that long reach configurations experience.
What truly sets our designs apart is the tapered boom profile that distributes stress more evenly across the entire structure. This thoughtful engineering detail significantly extends the operational lifespan of the equipment while maintaining exceptional performance in demanding mining environments.
Hydraulic System Optimization
The extended reach of these specialized booms creates unique hydraulic challenges that must be addressed through careful system design. Tiannuo's long reach systems feature upgraded hydraulic cylinders with enhanced sealing technology specifically designed to withstand the increased pressure requirements of extended reach operations.
Our hydraulic configuration includes:
①Larger diameter boom cylinders to handle increased leverage forces
②Pressure-compensated valves that adjust flow based on load requirements
③Specialized flow control that maintains precision during combined movements
④Additional counterbalance valves that prevent uncontrolled boom movement
The hydraulic lines running along the boom receive extra protection through reinforced mounting brackets and abrasion-resistant sleeves at all pivot points. This attention to detail prevents the common issue of hydraulic line failure that plagues lesser-quality long reach assemblies.
We've also incorporated load-sensing technology that automatically adjusts hydraulic pressure based on the working conditions, optimizing both performance and fuel efficiency when operating at various reaches and depths.
Performance Metrics and Capabilities
Tiannuo's excavators long reach boom delivers exceptional performance metrics that directly translate to improved operational efficiency. Our Tiannuo-18m model achieves a maximum reach of 17,300mm when paired with our extended arm configurations. This represents approximately a 70% increase in reach compared to standard excavator setups.
Despite this dramatic extension in reach, our engineering ensures minimal loss in lifting capacity. At full extension, operators can still expect to maintain approximately 40-45% of the standard lifting capacity, which exceeds industry averages of 30-35% for comparable extensions.
The connection size of 200/80 ensures compatibility with a wide range of excavator models while maintaining structural integrity. The boom maintains excellent stability even when operating at 75% of maximum reach with appropriate counterweighting.
Cycle times remain impressive with our optimized hydraulic system, averaging only a 15% increase compared to standard configurations despite the significantly longer distances the hydraulic fluid must travel. This efficiency directly translates to more material moved per hour and lower operating costs per ton of material handled.
Applications in Mining
Deep Pit Operations
Mining operations frequently require excavation at depths that standard equipment simply cannot reach safely or efficiently. Excavators long reach boom systems excel in these challenging scenarios by enabling operators to maintain a safe distance from unstable pit edges while still accessing the necessary depth.
In deep pit mining applications, our long reach assemblies allow for:
①Excavation at depths up to 12 meters while positioning the excavator on stable ground
②Precise material removal along pit walls without requiring the machine to descend into the pit
③Creation of proper drainage channels from a safe distance
④Removal of overburden material with minimal repositioning of the excavator
The ability to work from a single position while accessing various depths and angles significantly reduces the time spent repositioning equipment. This translates directly to operational efficiency gains of up to 35% in complex pit configurations.
Several mining operations have reported that by implementing our long reach boom systems, they've been able to eliminate the need for specialized equipment previously required for deep pit work. This consolidation of equipment requirements reduces capital expenditure and simplifies maintenance programs while improving site logistics.
Overburden Management
The efficient removal and placement of overburden material represents one of the most significant challenges in open-pit mining operations. Long reach boom and arm configurations transform this challenge by dramatically expanding the working radius of standard excavators.
With Tiannuo's extended reach systems, mining operators gain:
①The ability to precisely strip overburden material from a fixed position
②Capacity to load haul trucks positioned at safer distances from excavation faces
③Capability to create properly graded slopes from a single position
④Improved material segregation by placing different materials in designated areas without repositioning
The extended reach allows operators to create wider benches with fewer machine positions, enhancing both safety and productivity. The precision placement of materials at distance also reduces the need for additional dozing or grading equipment, streamlining the overall equipment fleet requirements.
Our mining clients have documented productivity improvements of 20-30% in overburden management tasks when utilizing properly specified long reach configurations. This improvement stems from the reduced cycle times associated with less frequent repositioning and the ability to manage larger working areas from a single setup.
Specialized Mining Tasks
Beyond the fundamental applications, excavators long reach boom systems excel in specialized mining scenarios that would otherwise require custom equipment or complex workarounds.
These specialized applications include:
①Reaching across water features or unstable ground to access material
②Working around existing infrastructure without requiring its removal
③Maintaining settling ponds and water management systems from stable ground
④Creating access routes in challenging terrain where standard equipment cannot safely operate
The versatility of long reach configurations makes them invaluable for mine reclamation projects where operators must reach across completed areas to restore slopes and vegetation without disturbing already rehabilitated sections.
The extended reach also proves invaluable when working near high walls, allowing operators to safely clear loose material or create drainage solutions without positioning equipment in potential fall zones. This capability not only improves operational efficiency but significantly enhances site safety by keeping both equipment and personnel away from hazardous areas.
Mine operators utilizing our long reach systems report substantial improvements in their ability to handle unplanned challenges that arise during operations, as the extended reach provides additional options for addressing obstacles without bringing in specialized equipment.
Compatibility
