TM 55-3810-306-15

NOTES:

Latch and tape closed all hinged openings: engine access doors, tool

compartment, and battery box. Cushion mirrors and tape against

frame.

Assemble wood joints in structures, planking, beans, and supports,

where bolting is not specified, using nails as follows: Nail plywood

sheathing to O/R blocks and braces to blocks using sixteen 20d nails.

Nail wheel chocks, bottom plates, and O/R box block braces through

into railcar deck using 20d nails. Where toenailing is required to

assemble 4 by 4, 4 by 6, 4 by 8, or 6 by 8 blocks or to nail blocks to

railcar deck, use 30d nails and predrill top members to .156-inch

diameter.

Loading sequence: Lift the crane carrier onto the flatcar. Center the

load laterally and position longitudinally. The blocking under the

outrigger boxes must support the weight of the load. Tires should be

just touching the railcar deck. First tension tiedowns 7, 8, 9, 10, 11,

12, 13, and 14 to seat the carrier against the O/R box blocks. Then

apply the other restraints and chocks (see note 4 below).

Each tiedown shown is a single length of .62-inch-die. wire rope

looped through a railcar stake pocket and crane carrier lug. Ends are

joined as shown in detail A. Tension all ropes to 3000 pounds and

torque rope clamps to 95-foot-pounds.
