How to Install an Excavator Telescopic Arm: Step-by-Step Guide 01 Should prepare these: Need 3 people ： 1 as driver and 2 as install man Make sure the excavator have additional pipe line Need Tool: Internal and external plug（M26x1.5H type） 2 sets Internal and external plug（3/4 female type） 2 sets Internal and external plug（1”female type） 2 sets Internal and external plug（19 US flat cut type） 1 sets open spanner: 17-19、18-21、22-24、27-30、30-32（2 sets） 36-41（2 sets） Adjustable wrench:450#、300# double offset ring spanner: 18、21、22、24 Quick wrench and socket Flat-head screwdriver， Phillips screwdriver 10# T-bar, pliers, suspender, thick top bar for shaft, sledgehammer   02 Remove the hydraulic pressure need to turn off the excavator and Remove the pressure from the hydraulic line First (A button on the pressure valve removes the pressure from the tubing Force, if the relief valve does not work, you can remove the liquid Pressure can also be removed from the tank cap)     03 Install the telescopic arm   04 Install the pipe line     05 The telescopic arm already connected     06 Let`s see how to install the bidirectional foot switch Replace the foot pedal switch with Bidirectional     07 The bidirectional foot pedal switch consists of four connector: T, P, A1, and A2. .The T port should be connected to the T port of the excavator's travel valve using a three-way joint to separate the oil flow. Similarly, the P port should be connected to the P port of the travel valve using a three-way connector for oil separation. Finally, the A1 and A2 connectors should be connected to the pilot control connector of the distribution valve.       08 Travel Valve Remove the rubber pad located on the cab floor to reveal the designated installation opening for the bidirectional foot pedal switch. Typically, this opening is situated on the right side of the cab. Find the T port and P port of the travel valve, which corresponds to the T port and P port connected to the foot pedal.   09 link pipe A1 and A2 are connected to the distribution valve. To locate the distribution valve, follow the breaker pipeline and observe where it connects to the distribution valve. Look for joint positions on both sides of the connection or at the corresponding middle position, where the valve covers are visible. Connect A1 and A2 to these two positions respectively. Find corresponding valve covers. The valve cover of the oil inlet pipe is typically connected to A1, while the valve cover of the oil return pipe is connected to A2. In the event of reversed action, simply swap the pipelines connected to A1 and A2.   10 Pipe Connection Diagram   11 after installation , should lube it Apply grease to the pin positions, the arm tube of the telescopic arm，there are many lubrication holes on the telescopic arm can add grease , the telescopic arm also should lube whole body!     Meta Description: Learn how to install an excavator telescopic arm safely and efficiently with this step-by-step guide.

The telescopic arm is a working device installed on the excavator. It is made of the fixed body and the moving body through the action of the telescopic cylinder to make the moving body extend and retract, so as to achieve a larger digging radius and a reasonable loading height.   Why is the telescopic arm produced:   1. Large effective working distance and high working height. Through the structure of the telescopic boom, a long distance can be achieved, and through the amplitude of the boom, a higher working height can be achieved, which is unmatched by traditional excavators. 3. It has good operation safety performance. The telescopic boom excavator has the function of load telescopic expansion. When performing stacking operations on uneven roads, it can stop at a position far away from the stacking point, open the stable outriggers, and use telescopic and luffing movements to complete the loading and unloading of goods; in the steelmaking workshop, It is also very convenient to clean and disassemble the furnace.   Specialized in manufacturing various long arms, demolition arms, sliding arms, telescopic arms, rock arms, clamshell buckets, grab, etc.   Email: Sophia@excavatorboomarm.com WhatsApp: +86 18127591702

Choosing the right telescopic arm for an excavator involves several considerations. Here’s a guide to help you make an informed decision: What is your excavator condition? Site Conditions: Evaluate the terrain and obstacles. A longer reach may be beneficial in tight spaces. What excavator model do you have ?   How long the telescopic reach to meet your requirement? Maximum Reach: Consider the maximum extended length needed for your projects. Retracted Length: Ensure it can fit in your job site or transport conditions when not in use.     Load Capacity Weight Limits: Check the load capacity of the telescopic arm. It should match or exceed the weights you plan to lift or move. Stability: A balanced load is crucial for safety and efficiency.   Construction and Materials Durability: Look for high-quality materials (like high-strength steel) that can withstand harsh conditions. Maintenance: Choose designs that allow for easy maintenance and repairs.   By taking these factors into account, you can select a telescopic arm that best meets your project requirements and enhances your excavator's capabilities.     Kaiping Zhonghe Machinery Manufacturing Co.,LTD. 9 Huancui West Road, Cuishanhu New Area, Kaiping City, Guangdong Province, China Contact sophia：18127591702 whatsapp: +86 18127591702    

When selecting a two-section telescopic arm, consider the following factors to ensure you get the best performance for your application: Material Quality High-strength steel (such as LG700 or Q355B) offers durability while keeping the arm lightweight. Reinforced pivot points and multi-layer welding enhance structural strength. Excavation Depth & Reach Choose an arm with an optimal telescoping range to suit your worksite requirements. Some high-quality arms provide an additional 20 cm of digging depth compared to standard models. Hydraulic Cylinder Design A double-slider cylinder design helps reduce vibrations and ensures stable movement. Well-sealed cylinders prevent oil leakage and extend service life. Bucket Compatibility Ensure the arm is compatible with different bucket types for various tasks like dredging, deep excavation, or demolition. Ease of Maintenance Look for models with an external bucket cylinder design, making replacements and repairs more convenient. A double-layer hose casing reduces pipeline wear and increases longevity. Manufacturer Reputation & After-Sales Support Website: www.excavatorrockbuckets.com Choose a manufacturer with proven expertise in custom excavator attachments. A reliable supplier should provide technical support, spare parts, and warranties for long-term reliability. ​ More information, pls contact Ada: www.excavatorlongarm.com My Whatsapp: +8615322105263 Tel/Wechat: 0086 15322105263 E-mail: abby@excavatorboomarm.com
