Hydraulic long ram jack - double pumps, which excel in the variability of use, are single-acting or double-acting hydraulic motors with rectilinear reciprocating motion. They are designed for general use in the automotive, construction, forestry, agricultural industries. These hydraulic cylinders serve as drive units for hydraulically operated equipment and are ideal for mounting in car body and other fixtures, even in-house production. The hydraulic long ram jacks are also equipped with a piston pump driven by a hand lever. The integrity of the piston rod with the pump presupposes minimal leaks and hydraulic oil leaks from the system. It is only used to expand in the vertical position and the object must be secured immediately after stretching with supports with adequate load-bearing capacity. Load capacity 8t. Min. length 620mm, max. length 1100mm. [***]
