Travelling clamp with removable rails

摘要

A travelling clamp unit of the type for extending and retracting a T-head clamping cylinder into and out of a T-slot of a press has a main frame which supports clamping cylinder drive means and the clamping cylinder when it is in a parked position in which it is retracted from the T-slot of the press. The main frame has rails which support the clamping cylinder T-head in the parked position and which are removable from the main frame so that the T-head can be dropped out of the bottom end of the main frame for removing the clamping cylinder from the travelling clamp unit.
