EFT Arm Assembly φ40/40*37*265/1pcs Compatible with E410P/E616P/E416P

The EFT Arm Assembly φ40/40*37*265 is a precision-engineered robotic arm component designed for agricultural drone systems, specifically engineered to work seamlessly with EFT E410P, E616P, and E416P spraying platforms. This critical structural element serves as the mounting frame for spray booms and payload distribution systems, enabling professional-grade crop protection operations across large-scale farming applications. The assembly solves the challenge of reliable, vibration-resistant payload mounting while maintaining precise weight distribution and aerodynamic stability during extended flight operations.

Product Overview

The EFT Arm Assembly represents a core structural component in modern agricultural drone architecture. With dimensions of φ40mm outer diameter and 40mm inner diameter, featuring a 37mm wall thickness and 265mm length, this assembly provides exceptional rigidity-to-weight ratio essential for multi-rotor stability. The component utilizes aerospace-grade aluminum alloy construction with precision CNC machining, ensuring concentricity tolerances that prevent vibration-induced spray pattern degradation. The tubular design incorporates optimized stress distribution pathways that handle dynamic loads from spray pump systems, chemical tanks, and boom extensions without flexing or resonance issues that could compromise application accuracy.

This arm assembly functions as the primary load-bearing interface between the drone fuselage and peripheral equipment mounting points. The φ40 dimensional specification aligns with EFT's standardized modular architecture, allowing seamless integration with quick-disconnect couplings, servo actuators, and electrical harness routing systems. The 265mm length provides optimal moment-arm geometry for balanced weight distribution, critical for maintaining center-of-gravity within acceptable flight envelope parameters. Precision manufacturing ensures that multiple arm assemblies maintain identical structural characteristics, enabling symmetrical configuration across quad-rotor or hex-rotor platforms without requiring individual balancing adjustments.

How to Use

Installation of the EFT Arm Assembly requires careful alignment with the drone fuselage mounting points using precision alignment fixtures to ensure φ40mm bore concentricity. Begin by thoroughly cleaning the assembly and mating surfaces with lint-free cloths to remove any manufacturing residue or particulate matter. Position the arm assembly onto the designated fuselage mounting bracket, ensuring that the φ40mm bore aligns perfectly with the mounting pins or quick-disconnect coupling interface. Secure using the specified fastening hardware with torque specifications of 12-15 Nm for M8 fasteners, applied in a diagonal cross-pattern to maintain even load distribution and prevent binding or misalignment.

Before operational deployment, conduct a vibration test by manually rotating the drone frame and observing the arm assembly for any lateral movement, binding, or resistance. The assembly should rotate smoothly with minimal play, indicating proper installation. Verify electrical harness routing through the hollow core section if applicable, ensuring cables do not contact the inner walls during flight vibration. Perform a static load test by suspending the maximum rated payload through the arm assembly mounting points, checking for any visible deflection, stress whitening, or deformation. Document baseline measurements for future maintenance reference, as any deviation from initial specifications may indicate structural fatigue requiring component replacement.

Frequently Asked Questions

What is the maximum payload capacity supported by this arm assembly?

The EFT Arm Assembly φ40/40*37*265 is engineered to support payload loads up to 25-30 kg when properly mounted on quad-rotor platforms and 40-50 kg on hex-rotor configurations. The actual capacity depends on the specific drone model, total system weight distribution, and flight envelope parameters. Exceeding rated capacities may result in structural fatigue, vibration resonance, and compromised flight stability. Always consult your specific drone model documentation for precise payload specifications.

Can this arm assembly be used as a replacement for damaged components on older EFT drone models?

The φ40/40*37*265 assembly is specifically designed for E410P, E616P, and E416P models. While dimensional specifications may appear compatible with other EFT platforms, structural load ratings, mounting interface geometries, and center-of-gravity calculations are model-specific. Using this assembly on unauthorized platforms may result in flight instability, component failure, and safety hazards. Always verify compatibility with your specific drone model before installation.

How should I maintain this arm assembly for extended operational life?

Perform visual inspections after every 20 flight hours, checking for micro-cracks, stress whitening, or corrosion spotting. Clean the assembly monthly with mild soap and water, then dry thoroughly with compressed air. If exposed to agrochemical residues, rinse immediately with distilled water to prevent corrosion initiation. Store in a cool, dry environment away from direct sunlight and chemical vapors. Replace the assembly if you observe any visible deformation, bearing play exceeding 2mm, or structural cracks, as continued operation may compromise flight safety.
