GENERAL INSTRUCTIONS
1.
Shippers should specify cars equipped with tie-down devices In the quantity required for Items "B" and "C", see
Sketches 2 and 3, when ordering specialized railroad freight equipment. In the event that conventional chain tie-downs
are supplied In lieu of devices specified, two of the four tie-downs required for each vehicle must have an adjustable
turnbuckle equipped with a safety lock device located in the chain for tensioning purposes. See Sketch 4. The chains
must be applied in the following manner.
a.
Attach the two chain tie-downs without the turnbuckle (See Sketch 5) to one end of the vehicle and to the
car tie-down facility. Pull tight as possible by hand and attach the hook into the appropriate link of the chain.
b.
Attach the two chains with the adjustable turnbuckles to the opposite end of the vehicle and to the car tie-
down facility. All four chain tie-downs should then be made taut by tightening the turnbuckles.
Note.
Load binders are not to be used in lieu of turnbuckles to tension tie-down chains.
2.
Vehicles must face in the same direction and be uniformly spaced along the length of the car to allow sufficient
space at each end of the car and between the vehicles for securement. Apply tie-downs parallel to each other at the
same end of the vehicle and down from the vehicle point of attachment to the tie-down facility. The angle of tie-down
must not be greater than 45 degrees.
3.
Tie-downs are not to be secured to axles of vehicles.
4.
Hand brakes on vehicles must not be set.
5.
Gear shift levers must be wire-tied in the neutral position.
6.
Open hooks must be secured with wire over the opening to prevent the hook from becoming disengaged from
the chain link to which it is secured.
7.
Turnbuckles when used to tighten chains must be wired or locked to prevent them from turning during transit
unless the turnbuckles are equipped with self-locking devices.
8.
When conventional chains are tensioned, care should be taken to avoid tensioning to such an extent that rub-rail
may start to rise. Tie-down devices, when attached to vehicle tie-down shackles, should not be tensioned beyond the
point where the springs of the vehicle start to compress. After chains are tightened they should be struck with a hammer
or bar to eliminate any possible misalignment of links. Further tightening may be required to take up any slack that
develops due to link alignment.
9.
Tie-down devices are not to be attached to the slots in the cushioned rub-rail adjacent to the position of the
recessed trailer hitches. This is to preclude the flange edge of the device, which rests over the inner side of the car's
center sill, from coming in contact with any portion of the trailer hitch when in recessed position and thereby restricting
the action of the cushioned rub-rail. When placement of vehicles on cars determines that securement points to the car
would fall in this area, conventional chain tie-downs (with or without turnbuckles) attached through the rub-rail slots will
be used.
