Wear pump tube made of special steel materials, through the inner arm quenching, carburizing chemical treatment, flange bushing hardness of 58-60 degrees, the life of the pipeline increased 3-5 times, allowing users to save time and money, replacing regular tube replacement trouble, improve production efficiency. Concrete delivery pipe products and specifications hardened tissue Description: The name of the organization HRC hardness of the base material thickness mm pearl fabric machine manually: manual cloth Technical parameters: the boom arm using two levels of folding, manual operation, 360 degree flexible, safe and reliable . Clear height of 5.5 meters this machine is especially suitable for walls, pillars, which are steel disc hernia occasions. Light weight, flexible, mobile tower crane with a convenient location. Specifications Model HGS12 HGS15 HGS18 cloth radius comprehensive description of the hydraulic system: (1) climb hydraulic jacking system and the host system share a pumping station, the connection between the two systems using imported high quality quick connectors, independent, free conversion conditions (Fabric / jacking), safe, reliable, and effective solution to system conditions the process of switching oil spill problem, avoid polluting the environment. (2) The machine adopts the open hydraulic system, the system is simple, reliable, easy to fault diagnosis and troubleshooting. (3) Valves boom used for the Italian Oilcontrol imported products with secondary overflow characteristics, can effectively ensure the smooth operation of the boom, to avoid influence by external cylinder pressure suddenly increased damage to the boom conditions, enhanced use Security. (4) the use of hydraulic rotary drive, low speed high torque hydraulic motor drive planetary gear can be used for 480 ° rotation, smooth rotary motion and accurate. For fabric machine characteristics are often in high-altitude operations, slewing brake normally open style, to ensure that fabric machine in non-working condition, the wind can turn the free skate, not because of the wind load is too large and damage the transmission mechanism and structure
