GENERAL INSTRUCTIONS
1.
Shippers should specify cars equipped with tie-down devices in the quantities specified in Item "B," and with
decks of sufficient capacities to withstand the total load of vehicles loaded thereon.
2.
Load binders are not to be used as tensioning devices.
3.
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 lifting shackles to the car tie-down facility. The angle of
the tie-down must not be greater than 45 degrees.

Tie-down chains must be free from twisted or kinked links, prior to their application to the vehicles.
5.
Hand brakes must be set.
