Abstract
Referring to FIG. (1), a sawmill has a pair of spaced end frames (1), (2), (4), a support beam (17) spanning the end frames and a saw carriage (56) moveable along the beam to carry a saw towards one end frame and then towards the other end frame. Each end frame has a ground engaging cross bar (1), a movable horizontal member (2) mounted on the cross bar (1) and an upright post (4). For each end frame the horizontal member (2) can run along the cross bar (1) to move the post (4) and consequently the beam (17) in adjustable increments towards one side of the sawmill and then towards the other side of the sawmill. The posts (4) support the beam (17) in a vertically adjustable elevated disposition.
