Unlock the Full Potential of Your Excavator
Are you looking to expand the working range of your excavator without buying a new machine? Our Telescopic Dipper Arm (also known as a sliding boom or extendable arm) is the ultimate solution for contractors who need extra reach and versatility.
Unlike standard fixed arms, our telescopic boom allows your excavator to extend its reach dynamically. By upgrading to our telescopic arm, you transform a standard excavator into a multi-functional powerhouse.

Key Features & Benefits of Telescopic Arm Excavator
Extended Reach & Depth: Instantly increase your digging depth and dumping height. Our telescopic design allows for a significant extension range, making it ideal for hard-to-reach areas.
Heavy-Duty Construction: Manufactured from high-tensile strength steel (BS900E), ensuring resistance to deformation and cracking under extreme pressure.
Precision Engineering: Equipped with high-quality seals and synchronized hydraulic systems to ensure smooth extension and retraction without jerking.
Customizable Fit: We specialize in excavator arm modifications. Whether you have a mini excavator (1 ton) or a large crawler excavator (50 ton+), we customize the arm to fit your specific make and model (Komatsu, Hitachi, Hyundai, etc.).
Cost-Effective Solution: Instead of investing in a specialized long-reach excavator, simply modify your existing machine with our sliding dipper arm to save on capital costs.
To help you decide if our Excavator Telescopic Dipper Arm is the right solution for your project, we have compiled the most common questions regarding installation, performance, and maintenance.

Production Details of Excavator Telescopic:

Will installing a telescopic arm affect the stability of my excavator?
Answer: Not if installed correctly. Our telescopic arms are engineered using Finite Element Analysis (FEA) to ensure the weight distribution matches your specific excavator model. For longer reach extensions, we often recommend adding standard counterweights to the rear of the machine to maintain optimal balance. We provide the exact specifications for required counterweights based on the arm length you choose.
How is the extension mechanism powered?
Answer: Our telescopic arms utilize a robust multi-strand steel wire rope tension system synchronized with your excavator’s hydraulic circuits. This system ensures smooth, synchronized extension and retraction. The hydraulic pressure drives the cylinder, while the high-tensile wire ropes ensure the stages move in perfect unison, preventing jamming or uneven wear.
Does this modification require permanent changes to my excavator?
Answer: No. Our telescopic dipper arms are designed to be bolt-on attachments. We replace your standard dipper stick with the telescopic unit. The hydraulic piping connects to your existing auxiliary lines (or main lines, depending on the setup). This means you can revert your excavator back to its original configuration if needed, preserving the machine's resale value.
What kind of maintenance does a sliding boom require?
Answer: Maintenance is straightforward. The primary focus is on the multi-strand wire ropes and the sliding pads.
Wire Ropes: Regularly check for tension and lubricate to prevent corrosion.
Sliding Pads: Inspect the wear pads between the sliding stages and replace them when significant wear is observed to maintain tight tolerances.
Greasing: Standard daily greasing of pins and bushings is required, just like a standard arm.
Can I use a hydraulic hammer or breaker with this arm?
Answer: Generally, telescopic arms are designed primarily for digging, grading, and dredging where reach is more important than impact force. While the arm is built from high-strength steel, using a breaker creates shockwaves that can damage the telescopic mechanism and wire ropes. We recommend using a clamshell bucket for digging or a grab for material handling. If you must use a breaker, please consult our engineering team first.
