Screw Jack

In some cases it necessary to take the job to high height & to hold the job for certain amount of time, in these cases screw jack satisfies the necessity , these are similar to general purpose jacks in the working principle but differ in the size & shape where the plungers are screwed to the cylinder which has to be operated manually & are taken ground as a base. With the aid of this Hydraulic screw jack one can lift job to a certain height & can do his work solely without any aid of labour, cranes or lifts. Jami Hydraulics is an ISO 9001:2015 certified manufacturer of Hollow plunger type hydraulic Jacks designed specifically for reliable, trouble free operation, making it ideal for heavy duty applications & are built to withstand Heavy Loads A Safety Factor of 2.5 or better is built into cylinder.

The Safety Factor is a function of the critical buckling load determined basically by the length of the cylinder and cylinder extensions Forces. Every cylinder is individually tested before leaving our plant to assure proper and leak free operation
