Abstract
A mobile machine for preparing rails for welding comprises an elongated bridge-like machine frame extending in a longitudinal direction, the machine frame having an upwardly recessed frame portion extending between opposite ends of the machine frame and defining a work space, and undercarriages support the opposite machine frame ends. Rail lifting devices are mounted on the machine frame for displacement in the longitudinal direction, and drives vertically adjust the rail lifting devices. The machine further has support shelves for storing rails on the machine frame.
Claims10
A mobile machine for preparing rails for welding, which comprises
- (a) an elongated bridge-like machine frame extending in a longitudinal direction, the machine frame having
- (1) an upwardly recessed frame portion extending between opposite ends of the machine frame and defining a work space, and being comprised of
- (2) two carrier beams extending parallel to each other in the longitudinal direction and being transversely spaced from each other,
- (b) undercarriages supporting the opposite machine frame ends,
- (c) rail lifting means mounted on the machine frame for displacement in the longitudinal direction,
- (d) drive means for vertically adjusting the rail lifting means,
- (e) means for supporting rails on the machine frame,
- (f) an operator's cab mounted at one of the machine frame ends,
- (g) access steps leading from the cab to the work space between the carrier beams for enabling an operator to reach the work space from the cab and to leave the work space through the cab, and
- (h) a boundary means extending in the longitudinal direction below each carrier beam for securing the work space within the gage.
A mobile machine for preparing rails for welding, which comprises
- (a) an elongated bridge-like machine frame extending in a longitudinal direction, the machine frame having
- (1) an upwardly recessed frame portion extending between opposite ends of the machine frame and defining a work space,
- (b) undercarriages supporting the opposite machine frame ends,
- (c) rail lifting means mounted on the machine frame for displacement in the longitudinal direction,
- (1) the rail lifting means comprising a crane supported by undercarriages for displacement in the longitudinal direction,
- (d) drive means for vertically adjusting the rail lifting means,
- (e) means for supporting rails on the machine frame,
- (f) an operator's cab mounted at one of the machine frame ends,
- (g) a loading platform at the opposite machine frame end, the loading platform being at a lower level than the upwardly recessed frame portion, and
- (h) guide rails atop the machine frame extending in the longitudinal direction above the loading platform, the guide rails supporting the undercarriages of the crane.
