30-ton Power Twin Single-Acting Hydraulic Ram
Center-Hole, Power Twin Ram
Use this ram on Grip-O-Matic pullers, Push-Pullers, and shop presses. OTCs center-hole ram is ideal for jobs that require a great deal of force and a relatively short stroke. Compared to the force it develops, the center-hole Power Twin ram is light-weight, compact, and easy to handle, permitting its use in confined quarters. Center-hole feature permits extending jacking screws, cables, puller screws, etc., straight through the ram.
Quick Change Inserts
For added job versatility, the Power Twin ram also features a basic head which allows the operator to change from a tapped hole to a plain hole by merely changing the head insert (held in place by a socket-head set screw). In certain applications, the use of
a plain insert is desired, since it permits using a speed nut for necessary readjustment after the ram has been extended,rather than turning the screw with a speed crank.
