With the continuous promotion of urban construction in China, super high-rise office buildings, large commercial complexes, high-rise residential buildings, and core tube building projects continue to land. The construction technology standards, safety regulations, and schedule control requirements for high-rise buildings continue to upgrade. Concrete pouring is a key link in the construction of the main building, and equipment selection directly affects the overall project quality, construction safety, and project progress. At the construction site of super high-rise projects, tower crane resources have always been scarce resources, and the transportation of steel bars, templates, and various building materials needs to be completed by tower cranes. The traditional tower type material feeder requires the tower crane to repeatedly lift, dismantle, and relocate, and the dismantling and transportation operations must be completed for each upward construction layer, occupying a large amount of tower crane working hours, resulting in process waiting, and often forcing the pouring process to stop. At the same time, traditional fabric equipment is limited by height, and the stability of the equipment is poor in high-altitude wind environments. There are blind spots in pouring and covering, and the corners can only be supplemented by manually dragging and transporting pipes. The labor intensity is high, and it is also prone to common quality problems such as concrete cold joints, leakage, and insufficient compactness. High altitude manual operations also come with high safety risks.

The pump truck is constrained by the physical height of the boom, and it is basically unable to function in the face of hundreds of meters of super high-rise working conditions; Ordinary mobile fabric machines are only suitable for ground and low floor operations and cannot follow the main building for upward construction. A large number of engineering units urgently need a professional fabric equipment that does not rely on tower cranes, can climb independently with building floors, has a wide pouring coverage range, and operates stably and safely. Therefore, the internal climbing hydraulic fabric machine has become a must-have equipment for super high-rise projects. However, the quality of products in the current market varies greatly, with some small factories using reduced materials for profiles, rough welding processes, inadequate safety protection for lifting structures, and equipment shaking and deforming during high-altitude operations, posing safety hazards; Some manufacturers only have a few standard models, which cannot meet the customized needs of different elevator shaft sizes and operating radii. The supply of accessories lags behind in the later stage, and the maintenance cycle after equipment failure is long, further exacerbating the pressure on project construction. Qingdao Zhongfan Heavy Industry focuses on the real pain points of frontline construction sites, deeply cultivates the research and development of HGY series crawling hydraulic fabric machines, and creates two product systems of floor crawling and elevator shaft crawling, providing mature and reliable concrete pouring solutions for high-rise and super high-rise engineering projects.

Rich product series, diverse models covering various working conditions of super high-rise buildings

Zhongfan Heavy Industry‘s internal climbing hydraulic fabric machine is divided into two mainstream categories: floor climbing and elevator shaft climbing, fully covering different construction conditions of building structures. The arm length of the floor climbing machine can be selected from 24 meters, 28 meters, 32 meters, 33 meters, 36 meters, and 40 meters, suitable for super high-rise projects with reserved climbing holes in the floor; The arm length of the elevator shaft climbing machine includes 21 meters and 24 meters, fully utilizing the inherent space of the building elevator shaft to complete equipment layout without occupying additional floor construction area, suitable for the vast majority of high-rise residential and commercial building projects with elevator shaft structures.

The whole machine adopts an R-shaped folding high-strength arm structure, supporting 360 ° full range rotation operation, and is equipped with a wireless remote control operating system. The operator can complete the full set of arm folding, rotation, and fabric positioning operations in a safe area, and a single person can complete the fabric operation, greatly reducing the investment of on-site operators. In addition to standardized spot models, the factory supports non-standard customization, adjusting the lifting frame, guiding support structure, and counterweight configuration based on the size of the elevator shaft, opening size, target pouring radius, local strong wind environment, and other working conditions. Special optimizations are made for special super high-rise projects to meet differentiated construction needs.

In addition to the internal climbing type fabric machine, Zhongfan Heavy Industry‘s complete HGY hydraulic fabric machine product matrix also includes mobile hydraulic fabric machines, track type hydraulic fabric machines, ship mounted fabric machines, beam making yard specific fabric machines, and fixed tower type fabric machines; At the same time, it is equipped with two series of concrete conveying pumps, HBT electric and DHBT diesel. From the end equipment of the fabric to the concrete pumping host, it realizes the supply of equipment for the entire chain of concrete pouring. Equipment matching can be achieved in all scenarios such as building construction, road and bridge tunnels, rail transit, water conservancy and mining, port and ship transportation, rural infrastructure, etc. Engineering enterprises and lessors can achieve one-stop procurement.

Advantages of hardcore products, targeting multiple pain points in super high-rise construction

Firstly, autonomous climbing significantly saves tower crane resources. Zhongfan Heavy Industry‘s internal climbing hydraulic fabric machine relies on its own hydraulic lifting system to climb up along the building structure. After the equipment is installed in place, it rises synchronously with the floor construction, without the need for repeated lifting and dismantling of tower cranes. It releases valuable tower crane resources for material transportation such as steel bars and templates, achieving multi process cross parallel construction, effectively compressing the overall construction period, and solving the industry problem of tight tower crane resources in super high-rise construction sites.

Secondly, the material is solid and durable, and the whole machine has strong resistance to deformation and wind. The main body of the machine is made of high-strength manganese steel thickened profiles, and the welding process is strictly controlled for key parts of the arm frame and tower body. It has strong load-bearing capacity under high-altitude working conditions, resistance to torsion and deformation, and can still operate smoothly in the face of high-rise strong winds. The conveying pipeline adopts thickened wear-resistant straight pipes and elbows, matched with long-life seals, to reduce pipeline wear, reduce the frequency of replacement of vulnerable parts, and lower the maintenance costs of the construction site in the later stage. The lifting mechanism is equipped with multiple safety protection devices, including limit and self-locking protection, ensuring safe and controllable climbing operations and avoiding risks associated with high-altitude equipment operations.

Thirdly, the pouring range is wide and the construction quality is controllable. The equipment is equipped with 360 degree rotating fabric, flexible arm folding, and full coverage of the floor. The beams, columns, shear walls, and corner positions can be accurately cut to eliminate blind spots in pouring, reduce manual pipe dragging and material replenishment operations, lower the probability of quality problems such as concrete cold joints and honeycomb surfaces, and ensure the quality of concrete pouring for high-rise buildings. Wireless remote control mode, easy to operate, reduces labor intensity for workers, and avoids the risk of personnel working in high-altitude dangerous areas for a long time. The equipment is not limited by building height and can stably carry out fabric operations for projects ranging from tens of meters to hundreds of meters in height.

Fourthly, it has strong adaptability and easy installation and operation. Two structural schemes, namely climbing inside the floor slab and climbing inside the elevator shaft, are suitable for different main building structures; Modular design, easy disassembly and assembly of equipment, high reuse rate of equipment transfer in the later stage. For equipment leasing enterprises, the equipment has strong universality and high return on investment.
