Heavyweight cylinders

Tox-Power package cylinders develop from 1 to 200 tons of force with shop air and have automatic activation of power stroke. They operate from pressure of 90 or 145 psi for strokes to 400 mm. A 3-way sequence valve activates power stroke when rod meets resistance; power stroke also can be activated by timer or limit or proximity switch. Tox Pressotechnik LLC, (630) 393-0300, www.tox-us.com
