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 ram is lightweight, compact, and easy to handle, permitting its use in confined quarters. Center-hole feature allows extending jacking screws, cables, puller screws and more to be inserted through the ram.
