Xiangyu Baoyuan 300m model four-section boom truck crane arm leads the way in revolutionizing high-altitude lifting operations with efficiency.

Xiangyu Baoyuan 300m Four-section Arm Vehicle-mounted Crane Boom Overcomes Multiple Challenges in High-altitude Lifting Operations In the fields of super high-rise and wind power hybrid tower hoisting, there have been three major pain points for a long time: multiple sections of arms are prone to swaying at high altitudes, resulting in poor alignment accuracy; frequent repositioning delays the construction schedule; and the strong wind loads at high altitudes pose a risk of structural fatigue. This has caused great troubles for the construction teams - repeated adjustments during the hoisting of super high-rise steel columns consume a lot of time, the assembly cycle of wind power hybrid towers is long, and the hoisting of large bridge tower columns requires the coordination of multiple equipment. To address these core problems, Xiangyu Baoyuan has launched the 300m Model Truck-mounted Crane Boom 4 Sections. With its technical advantages of "fewer sections, strong load-bearing capacity, and excellent wind resistance", it achieves full coverage of installation in one go, with less repositioning, significantly improving the hoisting accuracy and efficiency, and shortening the assembly cycle of wind power hybrid towers by 50%, and reducing the number of hoisting moves for super high-rise structures by 80%.

product overview

The core value of this four-section boom truck is to provide an "efficient, stable and integrated solution" for high-altitude lifting operations. Its main application areas cover key fields such as super high-rise buildings, bridges, wind power, and chemical plants. From a value perspective, with its 4-section arm design, it can enhance the lifting capacity at the tip of the arm, reduce the influence of wind loads, and achieve millimeter-level positioning accuracy, balancing efficiency and safety. From an application perspective, in the construction of core cylinders of super high-rise buildings, it can cover the entire standard floor at once. For large bridge tower column lifting, it can achieve "heavy load with short arm and precise with long arm" functionality with one machine, and for wind power hybrid towers, it can reduce vertical swaying. For large-scale thermal power chimney construction, it can ensure continuous operation without removing the arm. As a key component of aerial work vehicles, it forms a collaborative closed loop with Excavator Parts and Tower Crane Accessories. In high-altitude engineering projects, it becomes the core support for breaking through the bottleneck of lifting efficiency and reducing safety risks, completely changing the traditional situation of "low efficiency and high risk" in high-altitude lifting operations.

Product parameters

Product parameters and technical design are deeply adapted for the highest working conditions: The Product Model is specially customized for 300m, precisely matching the interface of the corresponding lifting equipment, and can be put into use without additional modification; type adopts a 4-section arm design for streamlined design, reducing 2 sets of telescopic cylinders and pulleys compared to a 6-section arm, and the weight at the arm head is reduced by approximately 1.8 tons, with the lifting capacity at the tip of the arm increasing by 6-8% under the same torque; size is fixed at 4239*168mm, and when retracted, the shortest length is only 28m, which is convenient for installation on a 60m narrow base. When fully extended, the arm can reach 80m, covering a diameter of 160m, significantly reducing the need for secondary relocation; it is equipped with a 110kW variable frequency lifting mechanism and a triple safety system of torque, weight, and wind speed, which not only ensures safe heavy-load operation and high-efficiency empty hook operation, but also avoids risks of working at heights, fully meeting the requirements of 300m-level high-altitude operations.

Product Model	type	size
300m	4-section arm	4239*168mm

Core product features: Meeting the core requirements for high-altitude hoisting.

1.Higher efficiency and greater capacity: The 4-section arm design simplifies the structure and reduces the weight at the arm head. Even when fully extended to 80m, the tip of the arm can still lift 4.8t. When shortened to 30m, the maximum lifting capacity reaches 32t. The rated lifting moment is 7360kN·m, which meets the requirements for positioning large-tonnage steel structures.

2. Superior site adaptability: The compact size of 28 meters after retraction is suitable for installation on a 60-meter-wide base. With an extension of 80 meters, it covers a range of 160 meters. This model can achieve full coverage in scenarios such as super high-rise buildings and large factory areas with a single installation, reducing the frequency of equipment relocation.

3. More stable against wind: With fewer sections and fewer crossbeams, the frontal area is reduced by approximately 12%. At a height of 300 meters, the wind load is smaller, and the structural fatigue life is longer. Combined with a triple safety protection system, the 80% rated torque automatically reduces the speed, and the 110% force triggers an emergency power-off.

4. Precise, efficient and time-saving: The telescopic movement and rotation of the small vehicle adopt a variable speed positioning mode, achieving millimeter-level positioning accuracy. The lifting mechanism supports 2/4 speed switching, balancing heavy-load safety and empty-hook efficiency, significantly reducing the hoisting adjustment time.

Practical Usage Tips: Ensuring Safety and Efficiency in High-Altitude Operations

1.Before starting the operation, check the dimensions (4239*168mm) against the site conditions. Based on the lifting scenario, plan the arm length combinations. For super high-rise coverage, select the 80m fully extended mode; for heavy-load bridges, choose the 30m short-arm mode to avoid waste of resources.

2. Before conducting work at heights, it is essential to inspect the three safety systems and ensure that the wind speed does not exceed the limit of 12m/s. In scenarios such as wind turbines and super high-rise buildings, additional wind-resistant measures must be implemented to eliminate the risk of wind loads.

3. When changing the lifting gear ratio, it is necessary to conduct a no-load test first to ensure the stable operation of the variable-frequency motor. For large-tonnage lifting operations, the low-speed gear should be used first, and the worm-speed positioning mode should be enabled when precise alignment is required.

4. Key points for daily maintenance include inspecting the telescopic cylinder, pulleys and hydraulic pipelines. After the operation, promptly clean the debris from the boom and perform rust prevention treatment. Special attention should be paid to the cleaning and inspection of the boom after high-altitude operations.

Customer benefits

The person in charge of the wind power project's hoisting operation said: "Previously, we used multi-section arms to assemble 140m hybrid towers. The high-altitude swaying was very severe, and the alignment required repeated adjustments. The entire process took 3 days. After replacing with Xiangyu Baoyuan's 300m four-section arm, the vertical swaying significantly decreased, and the alignment could be achieved at the millimeter level in one go. The assembly cycle was directly reduced to 1.5 days. Moreover, it has good wind resistance and is more reassuring for operations at 300m altitude. Now, we have replaced multiple wind power projects with this type of arm." Xiangyu Baoyuan has been deeply involved in the engineering equipment field and has a thorough understanding of the core demands of high-altitude hoisting. This 300m four-section arm of the truck-mounted crane, with its precise technical design, solves the industry's pain points and has become a top choice for hoisting in super high-rise, wind power and other fields.

Xiangyu Baoyuan also offers OEM customization of Underground Transport Vehicle Parts for well-known brands such as XCMG, and quotes are available at any time.
