Manually lift column hydraulic lift column is 5T hydraulic lift column is new hydraulic lift column hydraulic lift column is manually lift column is the latest offer Wholesale liter column hydraulic lift column of mine is mine application of hydraulic equipment manufacturing downhole tool liter column for the use of coal face increasing resistance micro HZWA metal prop set hold tight purposes. Compared with the mechanical lift column is not only compact, convenient and effortless operation, supporting high-speed fast, the most prominent advantage is the early support force. For mine roof fall accident reduction and ensure safe production effect is very obvious, won the miners welcome. The main technical parameters of the cylinder diameter:? 30mm piston diameter:? 10mm Handle length:?? 400 mm nominal setting load: 49KN (5T) the largest increase:?? 120mm Fluid rated working pressure:? 703Kg / mm2 gauge? Size:? standard gauge support process (full stroke swing handle 10 times the amount raised):? 31mm product categories in general, can be divided up column hydraulic lift column and gear up column is two former setting load. large, but not easy to overhaul the complex structure, the latter and vice versa. Later, with the use of large-scale investment hydraulic prop, mechanical lift column and metal friction pillars together gradually moved toward the edge of being eliminated. extensive application of hydraulic lift column stand up.
