Table 4-4. Application of Materials for Securing One Ml Tank Facing the Opposite Direction from that Shown in Figure 4-1. (For location of "items, " refer to figure 4-1.)

TM 55-2220-058-14

GENERAL INSTRUCTIONS

1. M1 tank brakes must not be set. Transmission selector must be in neutral.

2. Turret gun must be in the aft travel position, lowered, and locked in the gun elevation travel lock used for all

modes of transportation, and a cable (wire rope) must be used to secure gun tube while in transit. (The gun travel lock on

the turret ceiling will be engaged to the gun breech to anchor the gun tube in zero elevation during vehicle transit, and the

internal turret lock will be engaged in the locked position to prevent turret rotation.) Turret rotation and gun-elevating

controls must be wire-tied, if feasible, to prevent movement of turret and gun.

3. Turnbuckles of front and rear chain tiedowns must be tightened at the same time to avoid disturbing the tank

position.

4. Also applicable are General Rules 4, 5, 7, 11, 15(g), 19, 19A, and 19C in Section 1 of the Rules Governing the

Loading of Commodities on Open-Top Cars and Trailers, published by the Association of American Railroads. These

general rules are also found in TM 55-220-001-12.

Table 4-4. Application of Materials for Securing One Ml Tank Facing the Opposite Direction from that

Shown in Figure 4-1. (For location of "items, " refer to figure 4-1.)

Item

No. Required

Application

A thru D

Channels. For description, refer to paragraph 2-2c.

Shackles. At front of tank, attach one shackle to each tiedown fitting and one shackle to each lift

fitting. At rear

of tank, attach one shackle to each tiedown fitting.

Ring. Attach to towing pintle at rear of tank.

Wire rope, 3/8-inch. Wrap gun tube with protective material. Place thimbles on lifting eyes and apply

wire rope

in two complete loops: one around gun tube to left-rear lifting eye, the other around gun

tube to right-rear lifting

eye. Pull loops hand tight and secure ends of each loop with two 3/8-

inch U-bolt clips. Secure each thimble to

wire rope with one 5/8-inch U-bolt clip. (Not

required if tank has operable external gun-tube brace.)

Chains. Furnished with flatcar. Apply chains between tank tiedown fittings and anchor locations on

the deck of

the car, as described below.

Wire rope, 3/8-inch. If gun tube is not installed in the turret, secure turret to hull with 3/8-inch wire

rope, to

prevent turret rotation, and secure each loop with two 3/8-inch U-bolt clips.

LT1

and A7.

LL1

Chains. Attach chains to the left-front lift fitting shackle from chain anchors in B9, C8, and C7.

RL1

Chains. Attach chains to the right-front lift fitting shackle from chain anchors in C9, B8, and B7.

LT2

Chains. Attach chains to the left-rear tiedown fitting shackle from chain anchors in D36, D37, and

D38.

RT2

Chains. Attach chains to the right-rear tiedown fitting shackle from chain anchors in A36, A37, and A38.

Chains. Attach chains to the ring in the pintle from chain anchors in C36, C37, C38, B36, B37, and B38.
