Hydraulic jack is a device that is primarily used to lift heavy vehicle with the minimum effort. The jacks mount the vehicle and ensure stability to it while it undergoes repairing work.
In Hydraulic screw jack, the whole procedure is same as normal hydraulic bottle jack, but an additional feature i.e. THREADED RAM with THREADED RING (also called as safety ring) is used as an add-on from the safety point of view, where in when the RAM is lifted upto its maximum extended position, the ring is moved down so that, even accidentally if the safety valve pops off, hydraulic jack won't come down at all, giving additional ease to continue performing the maintenance work without any hassle.
Since the function of hydraulic jack is to offer stability to vehicle, quality and design is of most primary importance. Vishal Franko just understands this importance and for years has been supplying the world with jacks that just stand apart in terms of quality and performance.
