Product Details

Japanese and High-performance screw worm mechanical jack with screw structure made in Japan

Features

A mechanical jack is able to hold its position thanks to an internal screw.
Journal jacks with forging gear apply a great forces and good engagement.
Ratchet handle is designed for engagement both wheel and plunger,which are called "Wedge principle".Journal Jacks have also Good durability & stability.

Application

For jack-up,jack-down(lifting up and down for heavy load).
For positioning adjusting and support heavy load,and structures.
For bridge works.
For shipbuilding works.
For support of heavy load.

How to operate

1).Apply loads vertically and overall in the center of gravity of load.

2).Male sure to insert the handle lever into the bottom of ratchet handle.Incomplete insertion of handle lever leads to slipping off during operation.

3).Before using the jack for lifting,push the liner of the ratchet handle to "up" position and operate the handle lever up and down.

4).Before using the jack for lowering,push the liner of the ratchet handle ti "down" or "DN" position and operate(carefully) the handle lever up and down. 5).Take care always to stabilize load when jacking up and down.

*The ratchet handle will turn easily when there is no load on the jack.
