A tunnel-excavating machine weighing 67,000 pounds was recently
flown from the U. S. to Europe aboard Seaboard World Airlines' 747 Con-
tainership. The machine, which clears muck, rubble, and blasting debris
from the face of tunnels under construction, was flown to Europe in six
component parts, the largest of which weighed 33,100 pounds and measured 18
1/2 feet in length by 6 1/2 feet in width by 8 feet in height.

The machine is the Conway Mucker, built by the Goodman Equipment
Corporation of Chicago, Illinois. Typically the Mucker is mounted on rails
and brought to the face of the tunnel to remove muck and rubble caused by
construction dynamiting. The Conway Mucker digs into the rubble with a
steam shovel-like scoop and then lifts the debris toward the rear of the
machine where it is deposited onto a conveyor belt. The conveyor belt then
carries the rubble rearward where it is deposited into a rail car which
carries it out of the tunnel as part of a train of cars.

The Conway Mucker was transported to Europe for use in the con-
struction of the 10-mile long Furka Basis railway tunnel in Switzerland.
This tunnel belongs to the Forte Oberalp Railway which provides the rail
link between the cantons of Grison and Wallis. The tunnel is being con-
structed in two segments, each being dug toward the other. Conway Muckers
are in operation at the face of both tunnel segments.

Seaboard loaded the Mucker through the nose-loading door of its
747 Containership using standard airline cargo equipment. The dimensions
of the giant airfreighter's nose door - 11 feet 4 inches wide by 8 feet
2 inches high - permitted easy loading of the shipment. Once in the in-
terior of the aircraft the 67,000 pound shipment occupied about one-sixth
of the available space en the aircraft's main deck.
