One thing to keep in mind is that, if your leaders have a low distance from the front to the back … Continue reading Onshore Hammer Clearance Dimensions

Slide Bar Gripper

Once Vulcan got past designs such as this, the slide bar (the cam which turned the valve during operation) was retained in a ram using a key driven though the base of the slide bar.  The slide bar interfaced with the ram using a spherical block to allow rotation of the bar, necessary to compensate … Continue reading Slide Bar Gripper
