Why can the robotic arm of Xiangyu Baoyuan's 30-ton excavator be safely used for disaster relief and rescue work?
On construction sites, the most worrying issue is when the excavator's arm mechanism malfunctions - such as weld cracks, deformation errors, and the equipment having to be shut down for several days. The Xiangyu Baoyuan 30-ton replaceable arm is like equipping the equipment with a "backup weapon". If it breaks down, there's no need to wait for a return to the factory; it can be quickly replaced and the work can resume immediately.
What does the product look like?
This boom arm is specifically designed for 30-ton excavators. It is 4.2 meters long and has a key section width of 449 millimeters. The entire structure is forged from Q355B steel. The internal framework is made of reinforced steel plates welded by robots. The force arm ratio has been repeatedly verified by a computer, making it easier to dig and push materials.
Technical parameters are clear and unambiguous.
1.Compatible models: 30-ton excavators
2.Dimensions: 4200×449mm
3.Core technology: Robot welding + TS-V8 ultrasonic flaw detector for full weld seam inspection
4.Material: Main body Q355B steel plate, critical load-bearing areas are thickened

Three solutions to the tough problems
1.As a quality inspector: Each weld seam is scanned with ultrasonic "CT" technology, and cracks and pores have nowhere to hide.
2.The robot welds like embroidery: The welding trajectory is like a brushstroke in calligraphy, with a strength 20% higher than manual welding.
3.The layout of the reinforcement plates mimics the mechanics of a bridge: It imitates the structure of the cable tower of a suspension bridge, increasing the torsional resistance by 35%.
Which type of work requires it the most?
It is particularly suitable for scenarios that require frequent switching of clamping and loading functions, such as clearing debris, repairing roads and dams, and breaking hard soil during emergency rescue operations. Just like the Tower Crane Accessories we produce, it is a component that handles tasks at critical moments. In the Aerial Work Vehicle Parts field, this quick replacement design is also very popular.
Customized services are practical
If you are engaged in operations in frozen soil all year round, we will add a low-temperature toughness formula to the steel plates; if a hydraulic hammer needs to be installed, we will increase the thickness of the connecting flange in advance. Last year, a rescue team requested that the boom could be quickly disassembled and reassembled. We improved the design of the pin shaft hole position and reduced the replacement time from 3 hours to 40 minutes.
What savings can users achieve?
1.On-site replacement of the standby boom reduces project delay by 70%
2.After the weld seam lifespan is extended, 80,000 yuan is saved from avoiding major repairs for three years
3.Compared with the common storage system of Underground Loader Parts, the delivery of spare parts is two days faster
The production line holds hidden secrets
The largest double-gantry machining center in northern Jiangsu performs fine milling on the ear plates of the boom, with an error less than the diameter of a hair. The 3,000-ton bending machine presses out a 16-millimeter-thick steel plate with an arc shape like kneading dough, and drills and taps holes simultaneously during laser cutting. Each boom set undergoes ±30-degree repeated swinging tests before leaving the factory, simulating the strength of three years of use.
Testimonial from a practical user
The veteran from the Chuanxi Highway Bureau said: "During the flood season last year, we rushed to restore the road. This boom arm worked continuously for 72 hours without any deformation. It was even more durable than some original factory parts, and just as reliable as the Excavator Parts we use. Our warehouse always has emergency stock available, and we can support nationwide delivery within 48 hours."
Xiangyu Baoyuan adheres to the concept that "accessories should last longer than the main unit". This boom arm design has a service life of up to 10,000 hours. The complete quality inspection system endorsed by the world's top 500 company Xiangyu Group ensures that every component can withstand the test of the battlefield.
