(CAPACITY 80,000 POUNDS, ALLOWABLE OVERLOAD 10%)
This car was designed with the object of providing heavy capacity
Trucks with Air-Brakes, and at the same time reducing the dead weight
and maintenance to a minimum. This has become a recognized Standard
Logging Car, and as the design permits of considerable latitude in
length of car and centers of bunks, we do not hesitate to recommend it
to anyone who requires either Flat Cars or Trucks for strictly logging
purposes. The convenience of operation as compared with other types of
equipment is apparent. From an economic standpoint the comparison is
even greater. Some of the advantages are given below in detail:
1st. SIMPLICITY. Few parts to get out of repair, consequently car is
always in commission.
2nd. REDUCED COST. First cost is 18% less than Flat Car of same
capacity and equipment.
3rd. SMALL COST OF MAINTENANCE. More than 50% less than Flat Car.
4th. SAFETY OF OPERATION. Greatly increased over detached Trucks on
account of Air Equipment and rigidity of connection, and over Flat Car
in loading and unloading on account of skeleton construction.
5th. REFUSE NOT CARRIED TO DUMP. No deck to accumulate rubbish,
adding to dead weight of car, and carrying it to the dump where it is
discharged, often necessitating dredging to secure necessary depth of
water.
6th. REDUCED DEAD HAUL. Which is 30% less than Flat Car of same
capacity and equipment. This is important where heavy grades are
encountered.
7th. OPEN DESIGN. Facilitates operation of both loading and unloading,
lessening the time required and reducing the danger. At the same time,
ample protection is provided for Brake Rigging, eliminating danger of
being fouled by falling logs.
8th. INCREASED BUFFING CAPACITY. Connecting timbers forming backbone
of 300 sq. in. cross section, which offers great resistance to buffing
shocks.
Length over timber, 40 feet, can be furnished up to 56 feet. Length
over all, 42 feet. Width over connecting timbers, 30 inches.
Height to center of Coupler, 2 feet, 10 inches. Height to top
of Bunk, 48 inches. Width of Bunk, optional, 9 feet or 10 feet.
Bunk centers in illustration, 24 feet, but is optional with
purchaser. M. C. B. Automatic Couplers. Westinghouse Air Brakes.
Inside Hung Metal Brake Beams. Standard Diamond Arch Bar Truck
Frame. Metal Truck Bolster. Seattle Car Manufacturing Co.'s
Patent Cast Steel Body Bolster in combination with Patent Cast
Steel Bunks, riveted together, making solid section. Thirty-three
