Excavator Attachments Middle Arm Base

Product Introduction:

The middle arm base (also acknowledged as the core shaft seat or rear support) of an excavator's increase is a key load-bearing issue that connects the growth and the arm. It performs a indispensable function in transmitting loads, making sure stability, and enabling bendy movement. In the future, with the popularization of self-sensing lubrication constructions and predictive protection technologies, the core aid seat will similarly improve closer to an built-in course of "self-adaptation - self-repair - extended provider life". It will as a consequence come to be a core aggressive area of high-end excavators.

Product Advantages:

The benefits of the middle arm base are on the whole mirrored in structural innovation, cloth technology, ease of maintenance, and adaptability to quite a number scenarios. Features of the mechanical structure: The core aid seat is placed at the core section of the dipper arm and is hinged to the increase with the aid of a pin shaft. During operation, it transmits masses (such as bucket resistance and vibration torque) to the growth and chassis structure. Meanwhile, it serves as the rotation axis of the dipper arm, controlling the accuracy of excavation depth and angle. The core strengths of the core help seat in the excavator's boom—including built-in design, anti-eccentric load bolstered structure, centrally symmetric support, bolstered plate layout, adjustable design, and positioning anti-seepage—lie in its fairly dependable structure: the anti-eccentric load shape and imperative forging manner resolve the cracking issue. Intelligent functions: Its adjustable length/angle permits adaptation to more than one scenarios, and embedded sensors allow predictive maintenance.

Production Process:

Raw Material Inspection → Cutting → Forging → Heat Treatment/Tempering → Shot Blasting → Rough Machining → Ultrasonic Testing (UT) → Final Inspection → Cleaning  Packaging

Our team follows a strict workflow to ensure all products are ready for shipment, with no details overlooked. Here’s an overview of our process:

First, we prepare products in three steps before shipment: cleaning to remove dirt and debris, applying clear labels with key information, and checking rust-proofing for metal parts to prevent corrosion.

After preparation, we conduct a careful inspection, checking for defects and testing functionality. Any issues found lead to rework.

Approved products are then packed securely using appropriate materials. They’re stored in our climate-controlled warehouse, organized for quick retrieval, ensuring they’re ready for dispatch within 2 hours when needed.

Every step works to protect product quality, smooth logistics, and ensure reliability for customers.
