Working Principle¡êo Centrifugal Spinning Machine for spun concrete pole & pile is driven by variable speed AC Motor. High centrifugal force extracts the excess water from the fresh concrete placed in the mold. This process makes the concrete extremely denser. This in turn improves the quality of the concrete. The pole produced will have smooth surface with void cross-section. The spinning process starts with slow revolution. The concrete will be distributed uniformly over the full length of the mold. Following that, the revolution increases automatically to medium speed and finally to high speed. At the highest speed, a large magnitude of centrifugal force (~30g) acts to compact the concrete, and form the Standard quality poles. diameter 130-390mm

Double-position vertical vibration concrete pipe making machine Retaining the original core vibration machine advantages of good quality, safety, environmental protection, energy saving, immediately mould releasing, Our 300- 1200 double-pipe automatic vertical vibration concrete pipe equipment adopts the unique rising core technology ,including the following advantages and features: 1. High efficiency: 300- 800 forming two pipes at the same time, producing 10 pcs per hour of 2.5M of reinforced concrete drainage pipes;1000- 1200 forming single shape, 5pcs of 2.5M tube, total 200m pipes can be produced every day. 2. Product strong adaptability: 300 800 mm diameter pipe productions can be matched randomly (European similar devices can only produce the same diameter pipes). Reinforced pipes, unreinforced pipes, flat end, tongue and Groove, socket and spigot types of pipe-shape can be produced, and the device can be used for producing lining anti-corrosion pipeline. 3. High degree of automation: using computer control system, touch-screen display, vibration frequency, the concrete feeding speed is adjusted automatically, only one operator for the machine, greatly improved the productivity, labor is 10% to 20% of centrifugal and suspended roller process. 4.Reducing investment: double automatic vertical vibrated pipe transported by forklift to complete, no need the Overhead Crane in the workshop, thus saving more than 50% civil engineering costs (such as the overhead Crane beam and rail, also the concrete foundation) and the full cost of a whole set of 16 ton Crane. If calculated by the 40Km small diameter pipe production line put into each year, overall investment is only half of the centrifugation, suspended roller process. 5. Cost savings: double automatic pressing vibrating machine concentrate the advantages of vertical vibration machine, can save labor, cement , steam and other costs. After-sales service: Documentation provided by the supplier, service content Equipment before entering the factory drawings, Services content: 1. Vertical vibrated equipment layout. 2.

Working Principle: Vertical Vibration Casting pipe making Machine is one of the most advanced Concrete pipes making technology in the world at present, which integrate the technology of Mechanical, electric, Hydraulic, and the Automatics. This machine is easy to operate, much higher efficiency, and full-automatic. It can be used to produce the concrete pipe from DN600-3600mm, length 2-3 meter, and range from water drainage concrete pipe, Steel collar Jacking pipes, Box culverts, and the lined PVC or HDPE cement pipes and Manholes. The most important part of is the Vibrating Rod in the center of inner mould; the vibrator will produce high frequency exciting force while rotates at the fast speed, the exciting force will pass through to the inner mould, then to the vibrating transmission Spring, then to the outer mould. The concrete will become solid and density under the high strength vibration force, and form Quality pipe. Features: 1. Adopting the High Frequency Inner Vibrating, the concrete will become solid and density more evenly and more thoroughly. The pipe will be better in structure and stable in quality; 2. Using the half-dry cast concrete, the inner mould and Outer mould will be released instantly, so each diameter pipe just needs one set of moulds, which saves a lot of moulds investment, also saves a lot of time for workers assembling and disassembling the moulds, also improves the production efficiency. After releasing, the pipe could be curing by itself with the cement heat hydration, no need the steam curing, which also lowers the steam curing cost; 3. Wide range of production, this machine is capable to make not only water drainage concrete pipe, Steel collar Jacking pipes, but also Box culverts, Lined HDPE pipes and Manholes. 4. Variable Frequency motor, Inverter, Touch Screen and PLC, also the hydraulic technology are used in our machine. Top Quality and best price. The concrete pipe from DN600-3600mm, length 2-3 meter

Working Principal¡êo HGZ series Wire Cage welding machine is one of the most necessary equipment to produce reinforced concrete pipes. There is pushing style, another is the Pulling. It makes up of four systems: The Main plate; Pushing Plate; Diameter changing; and Cooper welder, they are working, driven by the separate motor. The Variable Frequency Ratio speed control system will promise the spiral pitch, angel of bell joint at regulated. Capacity: 300-3600mm, length 1-4 meter. Features: 1. Automatic PLC control, Man-machine interface, Touch screen. 2. Variable Frequency Speed control and inverter; 3. Pneumatic clamping system, Gear wheel chain on the main plate; 4.
