Fixed track hydraulic cylinder force adjustment thickened carbon steel comfortable handle storage hook,Say goodbye to "danger". The traditional strength device becomes tension-free and can not increase the strength after several times of use. Every time we innovate and upgrade, we only improve the exercise effect for safety,The micro rebound of hydraulic cylinder is safer. Advanced trip materials are introduced and formed at one time through special process to ensure the firmness, wear resistance and metal fatigue resistance of cylinder piston rod.Adjust the gear 1-25 in one second, and the switching force is easy to adjust in one second
