YDL series electric separate hydraulic pull at the most with the machine: the electro-hydraulic power source, separate from the top of the machine, die and other components. The machine has a track lifting, jacking, pulling unloading and other functions, is an ideal tool for mechanical maintenance work. YDL series electric separate hydraulic pull at most main technical parameters of the model with the maximum tension (T) of the piston stroke (mm) pull unloading range (mm) maximum working pressure (Mpa) YDL-Ⅱ 5-300 0-200 100-500 63 YDL-Ⅲ 5-300 0-200 150-650 63 Note: YDL series manual hydraulic tensile machine at the most with 5-50 tonnage limit Rally, YDL electric separate hydraulic pull pull 100 tons at the most with the machine up with ZB-63 electric pump.
