Jack features

The series indication displays the capacity in order to simplify the selection of models.

Capacities have been increased by 25% or more (up to 67%) over previous models.

The nominal capacity of 2 kN to 200 kN is the same for both the pressing load and the pulling load.

Makishinko jacks use a screw baffle structure for optional ball screw type jacks which has been granted an industrial patent for Makishinko.

The dimensions of the screw shaft end have been unified and standardized.
