What are the advantages of an extended excavator arm?

In modern infrastructure construction, many complex working conditions have already exceeded the working capacity of standard factory fitted excavator sticks. River dredging, deep water sediment removal, large slope trimming, ultra deep foundation pit excavation, high rise building demolition, port channel cleaning, tailings pond shaping and coastal revetment construction put strict requirements on working radius, digging depth and safe working height. If construction teams keep using the original short boom, they often have to rent extra barges, build scaffolding and arrange multiple auxiliary machines to work together. This solution not only raises the overall construction cost directly, but also extends the project schedule and brings more safety hazards caused by cross operation on site. Our factory focuses on the research and production of excavator long reach booms. Two section long reach booms and three section high reach demolition booms are both available for customization. They can fit excavators from 6 tons to 50 tons of all mainstream brands, including Sany, XCMG, Caterpillar, Doosan, Kobelco, Liebherr, Hyundai and other models. We design the boom separately according to the host machine parameters.

Our long reach booms adopt strict standards for material selection and manufacturing technology to meet overseas construction requirements. The main structure is built with high tensile Q690D wear resistant structural steel plate. Compared with ordinary steel, it has higher tensile strength and longer service life under continuous heavy load, sand and stone friction, and muddy water corrosion. All key hinge lugs and stress support areas are thickened and reinforced. The welding process uses argon arc welding for the base layer plus multi pass full welding. The welding seams are uniform and full, and non destructive weld inspection will be carried out before delivery. The connecting pins are made of integrally forged alloy steel and treated by quenching and tempering. They have outstanding performance in bending resistance, fatigue resistance and wear resistance. After a long time of frequent stretching and digging work, they are not easy to deform, crack or get stuck. Considering the hydraulic characteristics of long reach booms, we redesign the whole hydraulic pipeline route, select high pressure resistant and wear resistant hoses, and arrange pipelines neatly to reduce turbulence and pressure loss in the oil circuit. The boom stretches, retracts and lifts smoothly and stably. Even at the maximum extension limit, it maintains stable and controllable digging force. Operators can master it quickly with stable and comfortable control feedback.

The core value of an excavator long reach boom is breaking the working limit of the original stick, and greatly expanding the horizontal working radius, vertical digging depth and high altitude working height. For river regulation and inland dredging projects, the excavator can park on solid and stable river banks, and complete remote underwater silt cleaning, river bank trimming and river channel widening. There is no need for the excavator to enter the water or rent dredging pontoons. It fundamentally avoids the risk of overturning and machine water damage from water operation, simplifies the whole water construction process. In urban deep foundation pit construction, the long reach boom can reach the required excavation elevation in one operation. It reduces the frequency of machine repositioning and transfer, lowers the disturbance of repeated machine movement to the soil on the pit wall, better guarantees the stability of foundation pit supporting structure, and saves the cost of auxiliary equipment for earth transportation inside the pit. The three section high reach demolition boom is specially designed for demolition of old high rise buildings. It can send hydraulic hammers and pulverizers to high working surfaces. The excavator host stays in a safe area far away from falling debris. Operators finish breaking and dismantling inside the safe cabin. There is no need for workers to approach dangerous buildings closely. It greatly cuts the risk of safety accidents caused by falling objects and sudden wall collapse, and fully meets strict safety production rules on overseas construction sites.

We support full range customization and refuse one size fits all generic long booms. Before order confirmation, our engineering team will collect complete information from customers, including the exact excavator model, original counterweight data, hydraulic pump flow and pressure, site working conditions, target working radius, maximum digging depth, working height required by customers, and the size of the quick coupler. Based on these data, we draw exclusive engineering drawings one by one. We customize the total boom length, section angle, mounting hole position of lugs and layout of pipe brackets as requested. Meanwhile, we can customize supporting buckets, hydraulic hammers, hydraulic pulverizers and other front attachments to match the long reach boom, and deliver the whole matched set. It saves customers from the trouble of installation misalignment and power mismatch caused by separately buying attachments. Whether customers take water conservancy and municipal projects, urban renewal demolition, mine tailings pond treatment, coastal slope protection construction or lake dredging work, we can provide a complete long reach boom solution.

For construction contractors, purchasing a custom interchangeable long reach boom is a highly cost effective equipment upgrade choice. Compared with long term rental of dedicated long reach excavators, buying a long reach boom requires much lower investment. One excavator host can work with standard buckets, long reach booms, rippers, grapples and other attachments to realize multi purpose operation. A single machine can take on different types of projects, greatly improve the utilization rate of existing excavators and activate owned equipment assets. Every finished long reach boom will pass static load pressure testing, non destructive weld inspection and full set hydraulic pressure test one by one. We only arrange shipment after all indicators meet the standard. We provide complete installation drawings, operation guidelines and regular maintenance manuals. Professional technicians offer remote after sales guidance to help overseas customers finish installation, commissioning and troubleshooting rapidly. We help global construction contractors win bids for special construction jobs and deliver high difficulty long distance and deep excavation projects efficiently.
