Xiangyu Baoyuan 300m Four-section Arm Vehicle-mounted Crane Boom Overcomes Dual Bottlenecks of High-altitude Lifting Efficiency and Safety

In the fields of super-tall buildings and wind power hybrid towers where high-altitude lifting operations take place, there has long been a "core contradiction between efficiency and safety": The redundant multi-section structure leads to insufficient weight at the arm tip, and the high-altitude swaying affects the positioning accuracy; Frequent relocation and debugging not only prolong the construction period but also increase the equipment operation and maintenance costs; The extremely high working conditions result in strong wind loads, directly threatening the safety of operations. This has left the construction team in a dilemma where "pressure on the construction period and safety risks coexist" - The core tube construction of super-tall buildings requires repeated relocation of tower cranes, the assembly accuracy of wind power hybrid towers is insufficient, resulting in rework, and the lifting of large bridge tower columns requires the coordination of multiple equipment to increase costs. In response to this deep industry pain point, Xiangyu Baoyuan has launched the 300m Model Truck-mounted Crane Boom 4 Sections. With its core design of "reducing the number of sections, strengthening the load-bearing capacity, and optimizing wind resistance", it achieves a dual breakthrough in efficiency and safety, not only shortening the cycle of key lifting processes by more than 50%, but also reducing the risk of high-altitude operations from the structural root, and becoming the core of efficiency innovation in high-altitude engineering projects.

Product Overview

The core value of this four-section boom truck arm lies in the establishment of a "value optimization system for the entire cycle of high-altitude lifting". Its application scope has gone beyond simple material transportation and has become a key link that affects the total project duration and comprehensive cost. From a value perspective, it achieves "better performance with fewer sections" through the design concept of "better performance with fewer sections", breaking the traditional misconception that "the more sections, the better".

By reducing 2 sets of telescopic cylinders and pulleys compared to a 6-section arm, it not only reduces the weight of the arm head to improve lifting efficiency but also lowers the failure probability of the hydraulic system. The precise balance between the compactness of the retracted arm and the coverage of the extended arm fundamentally reduces the time loss and labor costs caused by equipment relocation. From an application depth perspective, it can not only be adapted to high-frequency scenarios such as full coverage lifting of super high-rise core columns, "one machine for two uses" of bridge tower columns, and precise assembly of wind power hybrid towers, but also in complex working conditions such as "tower within a tower" in urban complexes and chimneys in thermal power and chemical industries, by leveraging flexible amplitude adjustment and wind resistance advantages, it can avoid interference from already installed components and achieve continuous operations without disassembling the arm. As a key component of aerial work vehicles, it forms efficient synergy with Excavator Parts and Tower Crane Accessories, building a "one-time installation, full coverage, and low-dimensional efficiency" operation loop in high-altitude projects, promoting the transformation of the lifting process from "passive adaptation" to "active empowerment".

Product Parameters

The core competitiveness of the product stems from the precise dissection and technical implementation of the core requirements for high-altitude hoisting: Product Model is specially customized for 300m, and from the interface size to the carrying parameters, it is deeply matched with the 300m-level hoisting equipment. No additional modification is required to integrate into the existing operation system. Type adopts a 4-section arm design for simplification, seemingly reducing the number of sections, but actually achieving a performance leap through structural optimization - the fully extended 80m arm tip can still lift 4.8t, and when shortened to 30m, the maximum lifting capacity reaches 32t. The rated lifting moment of 7360kN·m is sufficient to meet the requirements for the positioning of large-tonnage steel structures. Size is fixed at 4239*168mm, and after retracting the arm, the shortest length is only 28m, perfectly adapting to the installation on a 60m narrow base. When fully extended to 80m, it can cover a diameter of 160m, significantly reducing the construction period loss caused by the secondary relocation of tower cranes. It is equipped with a 110kW variable-frequency lifting mechanism and a triple safety system of torque, weight, and wind speed. This not only achieves the high-speed operation efficiency of 90m/min with empty hooks and the safe operation of 35m/min with heavy loads, but also through the automatic speed reduction of 80% of the rated torque and the forced power-off of 110% at the limit protection, it builds a solid safety defense line for 300m high-altitude operations.

Product Features

1.Simplified structure leads to significant performance improvement: Through the optimized design of 4-section arms, the weight of the arm head is reduced by approximately 1.8 tons compared to 6-section arms. Under the same torque, the lifting capacity at the tip of the arm increases by 6-8%. Even in an 80-meter-long arm condition, it still maintains a lifting capacity of 4.8 tons, breaking the performance constraints of the redundant structure of multiple-section arms.

2. Full-cycle Cost Optimization: With a compact size of 28 meters for the telescopic arm, it is suitable for installation on narrow bases. The telescopic arm with a length of 80 meters can cover an area of 160 meters. In scenarios such as super high-rise buildings and large factory areas, it can achieve full coverage with a single installation, reducing the frequency of equipment relocation by more than 80%, and significantly lowering labor and maintenance costs.

3. Enhanced wind resistance and stability with increased safety redundancy: The fewer number of sections and fewer struts result in a reduction of the frontal area by approximately 12%. Under the 300m ultra-high wind condition, the wind load significantly decreases, and the structural fatigue life is greatly improved. Combined with triple safety protections such as wind speed limitation, it provides multiple guarantees for high-altitude operations.

4. Precisely and efficiently shorten the construction period: The telescopic boom and rotation system is equipped with a worm gear speed positioning mode, achieving millimeter-level positioning accuracy. The 110kW variable-frequency lifting mechanism supports 2/4 speed rate switching, balancing the efficiency of empty hook operations and the safety of heavy loads. The cycle of key lifting processes is shortened by more than 50%.

Professional Practical Tips: Deeply Explore the Full Lifecycle Value of Equipment

1.Precise selection of working conditions: Based on the working radius and lifting capacity requirements, the boom length is scientifically combined. For comprehensive coverage operations in super high-rise buildings, the 80m fully extended mode is selected; for heavy-load operations on bridge tower columns, the 30m short boom mode is chosen, maximizing the equipment's carrying efficiency.

2. Safety Management for High-altitude Operations: Before the operation, a lifting plan must be formulated based on the current wind speed (not exceeding the limit of 12m/s). For wind farms and super-tall buildings, additional wind-resistant measures need to be implemented. The tri-level safety system's hierarchical protection function should also be activated.

3. Efficiency optimization operation procedures: For large-tonnage lifting operations, the 4x speed reduction gear is preferred to ensure safety. When the hook is returning, the 2x speed high gear is switched to enhance efficiency. When precise alignment is required, the worm gear positioning mode is activated to reduce adjustment time.

4. Full-cycle maintenance strategy: Regularly inspect the telescopic cylinder, pulley system and hydraulic pipelines. Pay special attention to the structural condition of the welded parts. After the operation, promptly clean the debris on the boom and take anti-rust measures to extend the service life and safety redundancy of the equipment.

Customer benefits

The chief engineer of a certain super high-rise project stated: "When constructing the core tube of a 300-meter high office building, the most troublesome issues are the relocation of the tower crane and the accuracy of the lifting. Previously, we used multi-section arm tower cranes, and every time we completed two standard floors, we needed to relocate and debug. This alone accounted for 15% of the total construction period. After replacing with Xiangyu Baoyuan's 300-meter four-section arm tower crane, the 80-meter arm length can cover the entire standard floor at once, eliminating the need for repeated relocation. The positioning accuracy of the steel columns during lifting reached the millimeter level, and the overall core tube lifting period was shortened by 20%. More importantly, it has good wind resistance, and during operations at a height of 300 meters, the structural stability far exceeded expectations, significantly reducing the pressure of safety management." Xiangyu Baoyuan has been deeply engaged in the field of engineering equipment and has a profound understanding of the core contradictions in high-altitude lifting. This 300-meter four-section arm truck-mounted crane not only is a high-performance lifting equipment but also is the core carrier for promoting the efficiency upgrade and cost optimization of high-altitude engineering, providing full-cycle value solutions for super high-rise, wind power, bridge and other fields.
