Wheel Chocks are required only with standard draft
(non-cushioned) rail cars.
Nail wheel chocks to rail car deck using 40d nails.
Nail side bracing together to railway using 20d nails.
Tie Down - Two Types (Wire Rope or Chains).
WIRE ROPES with Clips: Minimum of 5/8" Diameter.
At each tie down lug place first wire rope at 45 degrees, other two at greater angles.
Thread each wire rope through a rail car stake pocket and a crane tiedown lug
and form one continuous loop. Overlap ends a minimum of 34 inches.
Clamp wire rope over lapped ends together and install six U-bolt type dips. Install
the first two clips in the same direction maintaining a distance of 3-3/4" between
them. Install the next two clips facing in the opposite direction. Continue until all
the clips are in place.
Apply tension to each wire rope (ends) using Chain Hoist and Cable Grip tool. Follow the tie
down guidance in Pamphlet No. 55-19. "Tie down Handbook for Rail Movement" with chain
hoist tension applied, torque nuts on U-bolts to 130 lbs. ft. If U-bolt breaks
when this amount torque is applied, loosen U-bolt nuts, increase cable overlap, replace
Install additional U-bolt type clips, and torque below breaking point. Remove Chain Hoist
and Cable grip tool.
Reeve three (3) chains through each of the two tie downs at crane front and through looped rail car stake pocket.
At each tie down place first chain at 45 degrees, other two at greater angles. Repeat tie down layout at rear of
crane. (12 Chains total). Apply tension by installing a load binder at each chain
Secure front jack cylinders with steel tape band (0.035" x 1.25").
Do the same with the two rear jack cylinders. Cushion surfaces to protect paint.
