Choosing the wrong arm length for a fabric machine is like burying profits in the floor slab

In the commodity concrete circles of Shandong, Henan, and Hebei, the biggest fear for the masters is not that there is no work to do, but that the arm length of the fabric machine is chosen incorrectly - the 12 meter one cannot reach the edge, and the 32 meter one takes up space and is slow to adjust. At the end of the day, the core mission of the fabric machine is only one sentence: to deliver concrete accurately and stably to the pouring point, without wasting a truckload of material or delaying a second.

Qingdao Zhongfan Heavy Industry Machinery Co., Ltd. has been producing fabric machines and concrete pumps for more than 20 years. From the earliest 12 meter manual rotation, it has been iterated all the way to today‘s HGY series hydraulic mobile fabric machines. The biggest feeling is that choosing the right one saves money. In this article, we will use a comparison table to explain the five mainstream models of HGY 12/17/21/24/32 meters.

The working principle of the fabric machine, explained in 30 seconds

The fabric machine is essentially; A concrete boom standing on the ground;. It consists of a chassis, a slewing support, a tower body, a large arm, a small arm, and an end hose. The hydraulic system drives the large arm to rotate 360 degrees, accurately delivering the pumped concrete; The stall; To every corner of the floor slab.

Base frame+counterweight: Ensure the stability of the entire machine, and support legs should be used on uneven ground.

Tower body: determines the lower limit of fabric radius, the higher the tower body, the larger the turning radius.

Big arm+folding arm: determines the upper limit of fabric radius, which is also the floor; Is it enough? "; The key.

Rotary bearing+hydraulic motor: achieve 360 degree rotation in the horizontal plane, and hit the discharge port wherever it is directed.

End hose+rubber spring shock absorber: prevents concrete segregation and ensures more stable discharge.

These five piece sets, even the masters of Zhongfan Heavy Industry can talk for half a day with their eyes closed. Durable leather is the bottom line, stable discharge is the real skill.

Comparison Table of Five Models of Zhongfan HGY Series

Model: Suitable for floor, overall weight (approximately), maximum turning radius, typical working conditions, and maximum operating radius

HGY126 floor and below 7.5 t 6 m12 m rural self built, villa, basement ceiling

HGY1710 floor left and right 9.5 t 8.5 m17 m small high-rise residential building, 6+1 western-style house

HGY2130 floors below 12 t 10.5 m21 m high-rise residential and commercial buildings

HGY2450 floors below 14.5 t 12 m24 m high-rise office buildings and complexes

HGY3280 floors below 22 t 16 m32 m super high-rise, subway station, bridge

What are the differences in applicable scenarios for different arm lengths

12 meter fabric machine: low unit price, light weight, can be pulled away by a crane weighing over 6 tons. The self built villa clusters in Shouguang and Liaocheng, Shandong, can almost conquer the world with one machine within 12 meters. The disadvantage is that the turning radius is small, and slightly larger underground garages cannot be turned around.

17 meter fabric machine: often referred to as; Small high-level artifact;. The 11 story western-style house project in Jiangsu and Anhui can cover the farthest end of the floor slab with 17 meters without occupying too much tower crane operation area. The Zhongfan HGY17 uses a thickened tower body, which has a stronger wind resistance than its peers.

21 meter hydraulic fabric machine: This is the sales king of Zhongfan. Six out of ten high-rise residential buildings in Jiaozhou, Jinan, Linyi, and Lianyungang are HGY21. The reason is simple - the arm length is sufficient, the price is moderate, and it can also be towed to the construction site. The main pouring of buildings below 32 floors can be almost completed within 21 meters.

24 meter climbing fabric machine: Admission ticket to high-rise office buildings. The overall weight of the machine is increased, and the boom is controlled by dual oil cylinders, making the fabric more stable. The CBD projects in Zhengzhou, Wuhan, and Hefei, with Zhongfan HGY24, have become; Standard configuration;.

32 meter floor slab fabric machine: a solution for super high-rise and large-scale infrastructure. The tower body, climbing system, and boom are all thickened and weighted, and installation requires a professional team. The 32 meter model of Zhongfan has been operating stably in several mines and bridge projects in Inner Mongolia and Qinghai.

Selection suggestion: Three steps to avoid pitfalls

First, look at the floor and floor dimensions: for a square building, the arm length is equal to half of the building width multiplied by 1.2; Rectangular buildings are calculated based on their long sides.

Looking at the site conditions again: if the site is narrow, priority should be given to horizontal layout; If the site is open and the buildings are high, priority should be given to internal climbing or floor slab construction.

Finally, let‘s take a look at the matching pump: HBT40-HBT60 motor pumps can be used for distances below 21 meters; It is recommended to equip DHBT60 diesel engine pump with dual safety for displacement and pressure above 24 meters.

Qingdao Zhongfan Heavy Industry, as a well-established manufacturer of fabric machines and concrete pumps in the Shandong Peninsula, has only focused on one thing for many years - making the equipment sturdy and durable, ensuring stable discharge from construction sites, and enabling customers to find people with just one phone call. That‘s also why the Zhongfan HGY series has become a frequent customer on the purchasing list of more and more people, from the urban villages in Jiaozhou to the mines in Inner Mongolia, from the Huangdao community to the high-speed railway project of China Railway Eighth Bureau.
