13m Long Reach Boom for CAT 312 Excavator
✅Product Summary
TheDW-312-13LR long reach boom is a 13-meter attachment designed specifically for the CAT 312 excavator, enabling the machine to operate well beyond its standard digging radius. This configuration is widely used for pond maintenance, shallow dredging, slope trimming, and extended-distance loading, where a conventional boom cannot reach efficiently.
Built with high-strength structural steel and precision-machined joints, this long reach boom set delivers stable performance on compact excavators while keeping fuel consumption and operating load within safe limits for the CAT 312 platform.
✅Main Features
✔ Extended 13m Working Envelope
The optimized boom–stick geometry expands the CAT 312’s reach by more than 40%, giving the operator better coverage when working across wide ditches, farm canals, and water embankments.
✔ Lightweight but Reinforced Structure
Although designed for a mid-size excavator, the boom sections incorporate internal stiffening ribs and a dual-layer plate design at stress zones to ensure durability without adding unnecessary weight.
✔ Smooth Hydraulics Compatibility
The hydraulic cylinder mounting points retain CAT layout standards, ensuring seamless connection with original or aftermarket cylinders, making the upgrade easy for contractors or rental fleet owners.
✔ Higher Stability for Long-Distance Work
Pin seat housings are CNC-machined for precise alignment, helping reduce vibration and preventing excessive wear on the main boom hinge even under extended reach operation.
✔ Complete Attachment Package
The long reach kit can be supplied with a stick,bucket linkage,hydraulic pipes, and hoses, enabling quick installation and immediate deployment on the jobsite.
✅Where the CAT 312 13m Long Reach Arm Performs Best
✔ Canal and Farm Irrigation Cleaning
Efficient for removing shallow mud and vegetation accumulated along long, narrow embankments.
✔ Slope Finishing and Bank Shaping
Ideal for water conservancy work where consistent slope profiles are required.
✔ Construction and Foundation Preparation
Useful for digging extended trenches for utility installations and for preparing large working areas.
✔ Small River and Pond Dredging
The 13m configuration provides enough reach for removing sediment from small water bodies without requiring the machine to enter the water.
✔ Sand, Soil, and Lightweight Material Handling
Excellent choice for long-distance loading tasks where a wide working envelope is necessary.
✅Advantages of the Dewanda DW-312-13LR
✔ Designed for Compact Excavators
The structural dimensions and weight distribution are tailored for the CAT 312 class, ensuring balanced machine performance without compromising stability.
✔ Enhanced Welding Strength
Critical joints are welded using robotic multi-pass welding, ensuring uniform penetration and long-term resistance to material fatigue.
✔ Reduced Maintenance Needs
Wear-resistant bushings and hardened pins provide longer service intervals, especially for contractors working in sandy environments or dredging operations.
✔ Options for Customized Configurations
Customers can request:
different stick lengths
special-purpose buckets
reinforced heavy-duty versions
piping setups for hydraulic attachments
Dewanda supports full OEM/ODM configurations to match unique project demands.

✅Counterweight Recommendation for CAT 312 with 13m Long Reach
The CAT 312 normally maintains good balance with its factory counterweight.
For long reach operation:
Standard dredging & trimming →no additional counterweight needed
Heavier bucket loads / continuous extended reach →+500–900 kg optional rear weight
Soft ground or water-edge work →track widening plates recommended
Dewanda can provide matching counterweights if required.
