Demolition projects benefit from the extended reach by allowing operators to dismantle structures from a safe distance, reducing exposure to falling debris and unstable elements. The precision control available with modern hydraulic systems enables selective demolition even at maximum extension, preserving adjacent structures while efficiently removing targeted elements.
Engineering Considerations
The 18000mm arm configuration requires sophisticated engineering to maintain stability and functionality at full extension. These machines feature enhanced hydraulic systems with precision control capabilities that compensate for the increased leverage forces at maximum extension. The minimum front-end turning radius increases slightly to approximately 5150mm, requiring additional planning for site movement.
Weight distribution becomes critical with the 18-meter configuration, and manufacturers incorporate extensive counterweighting systems to ensure stability during operation. The structural components of the arm itself utilize high-strength materials designed to resist the bending forces encountered during lifting operations at full extension.
Modern control systems in 18-meter excavator long arms incorporate advanced feedback mechanisms that provide operators with real-time information about load limits and stability parameters, helping to prevent overextension and potential tipping hazards while maximizing the effective working envelope.
How to Choose the Right Long Arm Excavator?
Project Requirements Assessment
Selecting the appropriate long arm excavator requires careful analysis of project-specific requirements. The first consideration should be the maximum reach needed for your application. If your project involves working across obstacles or requires access to areas beyond 15 meters, the 18000mm configuration likely represents the optimal choice. For projects with more moderate reach requirements, the 16000mm model offers excellent versatility with slightly improved lifting capacity.
Evaluate the nature of the material being excavated, as this significantly impacts bucket selection and overall performance. For lighter materials like silt or loose soil, larger bucket capacities remain viable even with extended arms. However, dense materials or rocky conditions may require smaller, reinforced buckets to prevent excessive strain on the extended arm structure.
Consider the working environment, including ground conditions and space constraints. Long arm excavators require stable positioning, with some models featuring extended track frames or outriggers to enhance stability during operation. Site access and transportation requirements also factor into selection, as longer arms may require specialized transportation arrangements.
