LONG REACH BOOM
Long Reach Boom & Long Reach Arm
River heavy industry specializes in the design, production and custom-made long-reach arms for various brands of excavators.
We focus on product quality, from stress analysis, material selection, technology process, design and manufacturing, the product’s structural strength, performance and quality are guaranteed. For the arm base better protection, an internal buffer plate and reinforced installed to withstand the tensile load, and increase the service life of the excavator’s long reach front/arm.
Also, we can design a variety of two-stage extended excavator long arms according to customer demands, which are mainly suitable for earthwork and deeper excavation operations; used in river dredging, port construction, subway construction, and building foundation excavation, with a wide range of operations and high efficiency and security.
In most cases, a long reach arm/boom is likely to be used with an amphibious excavator, which requires a farther digging distance due to the height of the amphibious undercarriage being higher than the traditional land excavator.
Application
Clean Up Waterways or Fish Ponds
Water Resources and Hydropower Engineering
Construction Transportation 、Subway Excavation
Product Advantage
Industry-standard welding technology
Good welding technology ensures the strength of the long-reach arm to meet the set standards and increase the service lifetime.
Automatic processing equipment
The cutting is fully automatic, as well as the bushing and key processing are fully automatic, which ensures that each pin on the arm is parallel, wear-resistant and noise-free.
Professional designing team
Product upgrades are carried out to greatly reduce the risk of cracking and breaking of the upper arm, based on the original product.
Advanced computer-aided design tools
The utility of two-dimensional drawing and three-dimensional design provides accurate data analysis for secondary development and private customized products, effectively shortening the production lead time

The main configuration of the excavator extension arm:
To better save the cost when users replace the extension arm, we have carefully analyzed which parts on the original car can be used back and which must be replaced. The standard configuration when replacing the standard arm with the extension arm is as follows:
One set of arm；
one bucket；
one bucket cylinder；
4 hoses；
3 butter pipes；
one set of connecting rod assembly；
one set of transport connecting rod；
6 pins；
