Long Arm Excavator Specifications
When it comes to specialized excavation tasks that require extended reach capabilities, long arm excavators have become indispensable equipment across numerous industries. These powerful machines are engineered with remarkable specifications that enable operators to access challenging work areas while maintaining operational stability and efficiency. The excavator long arm configuration significantly enhances the standard excavator's performance envelope, allowing for excavation at greater distances and depths than conventional models could achieve.
Long arm represents a critical advancement in construction machinery, particularly valuable in scenarios where standard excavators cannot safely or effectively operate. With specially designed boom and arm assemblies that can extend the machine's reach by several meters, these excavators excel in applications like deep trench digging, riverbed dredging, slope formation, and hard-to-reach demolition work. The extended reach doesn't just increase operational capability—it often eliminates the need for repositioning the machine or employing additional equipment, thereby improving project efficiency and reducing operational costs.
At Tiannuo Machinery, we've refined our long arm designs through years of expertise in the field. Our excavators feature impressive specifications including maximum reach capabilities of up to 17300mm, digging depths exceeding 12200mm, and excavation heights reaching 15300mm. These specifications position our equipment as ideal solutions for contractors dealing with complex projects in railway construction, mining operations, and various infrastructure development scenarios where conventional equipment falls short.
Maximum Reach: 15300/17300mm
Reach Significance
The maximum reach specification represents one of the most critical parameters when evaluating long arm excavator performance. This measurement, ranging from 15300mm to 17300mm in our advanced models, indicates the furthest horizontal distance the excavator bucket can extend from the center of rotation. This exceptional reach capability transforms how contractors approach challenging projects, particularly those involving water bodies, deep excavations, or areas with restricted access.
The extended reach proves invaluable when working across obstacles like rivers, highways, or existing structures without physically relocating the machine. Consider railway maintenance scenarios where operators need to clear vegetation or perform maintenance along tracks without disrupting rail operations. With our long arm configuration, the machine can remain safely positioned away from the tracks while still effectively reaching the required work zone.
Engineering Considerations Behind Extended Reach
Achieving such remarkable reach specifications requires sophisticated engineering solutions. Our long arm excavators utilize specialized boom and arm geometries that redistribute stress loads while maintaining structural integrity. The extended components are reinforced with high-tensile steel and strategic reinforcement points that prevent flexing or structural fatigue during operation.
Hydraulic systems receive substantial upgrades to manage the increased leverage forces created by the extended reach. Larger diameter cylinders, enhanced pressure ratings, and sophisticated flow control mechanisms ensure smooth operation even at maximum extension. These systems are complemented by counterweight modifications that maintain machine stability throughout the working envelope.
Application-Specific Reach Capabilities
Different industries benefit from specific reach configurations. In demolition applications, the extended reach allows operators to maintain safe distances from collapsing structures while still delivering precise control. For dredging operations, the increased reach enables excavation across wider water bodies without requiring costly temporary platforms or specialized floating equipment.
Railway construction and maintenance operations particularly benefit from these specifications. Track maintenance often involves working in confined corridors where conventional equipment cannot navigate effectively. The extended reach allows operators to position the machine on stable ground while still accessing the track infrastructure, significantly enhancing worker safety and operational efficiency.
Maximum Digging Depth: 11200/12200mm
Deep Excavation Capabilities
The impressive maximum digging depth of 11200mm to 12200mm positions these long arm excavators as exceptional tools for deep excavation requirements. This specification measures the vertical distance from ground level to the lowest point the bucket can effectively reach and excavate. Such remarkable depth capability revolutionizes approaches to foundation work, utility installation, and underground structure construction.
Traditional excavation methods often require staged approaches for reaching significant depths, including the construction of temporary ramps or employing multiple machines with different specifications. Our long arm configuration eliminates many of these complications by allowing single-position access to depths exceeding 12 meters. For mining and quarrying operations, this translates to more efficient resource extraction with reduced equipment deployment requirements.
Structural Integrity at Depth
Operating at such extreme depths presents unique engineering challenges that our designs effectively address. The extended arm assembly incorporates specialized joint designs and reinforced pivot points that maintain alignment and operational precision even under the substantial gravitational and material forces encountered during deep excavation work.
The hydraulic systems feature enhanced pressure compensation mechanisms that deliver consistent power throughout the digging cycle, regardless of arm position or extension. This ensures predictable performance and bucket control even at maximum depth, allowing operators to maintain excavation accuracy in challenging subsurface conditions including varied soil types and unexpected obstructions.
Industry-Specific Deep Excavation Applications
Various sectors leverage these depth capabilities for specialized applications. Utility contractors utilize the extended reach for installing deep sewer lines or water mains without extensive trench shoring or multiple machine repositioning. Construction companies employ these excavators for creating deep foundation elements or basement excavations for high-rise structures.
In the mining sector, these depth specifications allow for efficient overburden removal and resource extraction while minimizing haul road construction and maintenance costs. The ability to reach substantial depths from a single position dramatically reduces the operational footprint of extraction operations, supporting more environmentally conscious resource development approaches.
Maximum Excavation Height: 13500/15300mm
Vertical Reach Advantages
The maximum excavation height specification of 13500mm to 15300mm represents the vertical reach capability of our long arm excavator models. This measurement indicates the highest point at which the machine can effectively operate above its base elevation. Such impressive height capabilities expand the operational versatility of these machines beyond standard excavation tasks.
This vertical reach specification proves particularly valuable in demolition projects where controlled dismantling of multi-story structures is required. Operators can systematically deconstruct buildings from the top down without requiring specialized high-reach demolition equipment, reducing project complexity and equipment mobilization requirements. Similarly, in landscaping and forestry applications, this vertical reach allows for effective tree trimming and removal operations from secure ground positions.
Balancing Height with Stability
Achieving such remarkable height capabilities while maintaining operational stability requires sophisticated counterweight systems and hydraulic management. Our excavators feature optimized counterweight designs that precisely balance the extended boom and arm assembly throughout its operational range. This ensures the machine maintains a secure center of gravity even when fully extended to maximum heights.
The control systems incorporate automated stability monitoring that continuously assesses machine position and load conditions. When operating at extreme heights, these systems can provide operator guidance or implement protective limitations that prevent potential instability. These safety features allow operators to work confidently at maximum extension while maintaining operational safety margins.
Specialized High-Reach Applications
Various industrial applications specifically benefit from these height specifications. In waste management operations, the extended vertical reach allows for the construction and maintenance of higher material stockpiles, maximizing storage capacity within limited facility footprints. For construction contractors, these capabilities facilitate efficient loading of high-sided trucks or hoppers without requiring temporary ramps or multiple material handling operations.
Railway infrastructure projects often involve work on elevated track sections, catenary systems, or bridge structures. The substantial vertical reach of our long arm excavators allows maintenance teams to access these elevated components from ground level, eliminating the need for specialized access equipment or temporary platforms. This significantly improves project efficiency while enhancing worker safety on critical infrastructure projects.
