SUBJECT: THREE-STAGE UPRIGHT TILT ANCHORS

A new tilt anchor is available for use on three-stage uprights. The new design will prevent stress build-ups
that could cause cracks in the top anchor weld (Figure 1). Upright tilt anchors should be checked during
maintenance and repaired or replaced as required.

The original tilt anchors can be altered and repaired or replaced with new components. Table 1 identifies
the original anchors and cross-reference to new tilt anchor part numbers.

Effective Serial Numbers:

See Table I.

Welding Instructions:

IMPORTANT: These instructions pertain to welding in a critical area. They must be followed completely

and must be performed by a certified welder.

Electrodes:

Use E60XX electrodes, except as noted. Electrodes must be stored according to the electrode
manufacturer’s recommendations.

Material Specifications:

All material is

U.S.A. ASTM A36
German DIN 17100, MST 42-3
British B.S. 4360-1968

Except the tilt anchor plates that are T-1 steel

U.S.A. ASTM A514-70
German Pantanas 235
British Loycon QT

Welding Instructions:

Preheat to 125° F. (ll° C.) minimum in joint areas. No post heating required; let parts air cool.

Locating and Welding Procedure:

Remove the existing tilt anchor if cracked.

NOTE: Do not gouge out a cracked weld and reweld.

Clean up the anchor and alter per the alteration instructions, if new parts are not required. Remove weld
slag, moisture, oil, paint, and other contaminants prior to welding. If new parts are used, weld in the anchor
plates (Figure l). Otherwise, tack weld the anchor in place per the dimensions on Figure 2. Finish welding
per the welding symbols on Figure 1.

Alter the anchor as illustrated in Figure 3, using the following instructions. The alteration can be made with
the anchor on the upright, if there are no cracks.

1. Draw the line to be flame cut per the noted dimensions, Figure 3.

2. Flame cut slightly to the outside of the line.
