No. Reqd.

Application

Shoring (fig 5-5). Construct and locate as shown.

Blocks (detail 1, fig 7-4). Each to consist of six pieces of 2 x 12 x 28-inch lumber, cut as

shown in detail 1. Nail the two inside pieces together with three 12d nails, on each side.

Nail the outside pieces to the inside pieces with four 12d nails, on each side. Locate one

block against the front of each track as shown in figure 5-4. Toenail the heel of each block

on the two inside pieces to the trailer floor with two 30d nails. Toenail each side of the

block to the trailer floor with two 40d nails.

Blocks (detail 2, fig 7-4). Each to consist of six pieces of 2 x 6 x 23-inch lumber, cut as shown

in detail 2. Construct and apply (to rear tracks) in the same manner as item A, above.

End cleats. Each to consist of two pieces of 2 x 6 x 12-inch lumber. Center the bottom pieces

crosswires against the heels of items A and B, and nail the piece to the trailer floor with

four 30d nails. Nail the top pieces to the bottom pieces with four 30d nails in each piece.

Side blocks. Each to consist of two pieces of 2 x 4 x 108-inch lumber. Locate the bottom

pieces longitudinally against the inside edge of each track, and nail them to the trailer floor

with 30d nails spaced about 8 inches apart. Nail the top pieces to the bottom pieces in

like manner.

Braces. Each to consist of two pieces of 2 x 4 x length-to-suit (about 72-in.) lumber. Locate

the

bottom pieces between and at each end of item D, and nail them to the trailer floor with

30d nails spaced about 8 inches apart. Nail the top pieces to the bottom pieces in like

manner.

Shackles. Attach one shackle to each front and rear towing provision.

Wire rope, -inch, 6 X 19 IWRC. Attach wire rope to each shackle on the carrier and to the

tiedown provisions on the trailer, to form loop a complete (details 1 and 2, fig 5-3).

Clamps. Four for each loop (detail 1, fig 5-3).

Wheel blocks (detail 3, fig 7-4). Each to consist of six 2 x 8-inch length-to-suit lumber. Use 2

x 4-inch lumber to tie each set together. Place the blocks between the road wheels (two

on each track).
