Hollow-plunger缸CRI-FO系列

液压 双作用 螺纹的身体

CRI-FO系列是中空中心的圆柱体。适用于电缆张紧作业、拉力结构中的定位杆、滑轮的组装和拆卸、吊装以及电缆和拉杆的拉拔试验。张紧杆，dywidag, macalloy。使用回油系统的冲程比使用弹簧回油的气缸的冲程长。由于有回油系统，在所有操作条件下，回油时间更短。•采用螺纹体气缸定位更容易、更准确、更安全。•止动环不仅保证了操作人员的最大安全，防止柱塞过程，而且还出色地吸收偏心负载。•空心，高强度，花键可拆卸头。•雨刷减少环和杆之间的污染。•重量超过20公斤的机型配有手柄或吊环螺栓，便于携带。 Double acting oil return hollow plunger hydraulic cylinders in high pressure. Pushing force from 30 to 150 tons with a stroke range from 50 mm to 260 mm. Designed for cable tensioning operations, tensioning bars, assembly or disassembly. Operating pressure 700 bar. Guide surfaces are sized to guarantee optimal performance in absorbing the offset load and the end stroke ring increases safety for the operator by avoiding the extra stroke of the piston. Hydraulic jacks equipped with high strength gaskets for maximum durability up to 60° C, upon request it is possible to equip the cylinder with gaskets resistant to high temperatures up to 200° C. Furthermore, the presence of the wiper prevents contamination from impurities present in the environment of use.
