It consists of two inner and outer sleeves. The inner tube is made of +48mm welded steel pipe (wall thickness is between 2.5-3.0mm). The inner tube is provided with a pin hole at intervals of 100mm, which can be inserted into a return steel pin. The middle 60mm steel pipe (wall thickness is between 2.5-3.0mm) is welded on the outer tube. It is made of seamless steel pipe and is matched with micro-nut with a fine adjustment range of 1-100mm. The adjustable height range of independent support is 1.9m -- 4.5m.
