attach any bracing directly to the sheet metal trunk. Sheet metal lacks the necessary stiffness and
thickness for sound structural joints.
The engineer or contractor supervising elevator installation is ultimately responsible for determining
suitable guying and/or bracing methods and materials. Recommended maximum distance between lateral
bracing is 20' increments vertically at trunk flange seams to adjoining structure. The following
considerations are presented in addition to those set forth in
Mill Mutual Publication No F-646-75
:
1. Consider placing curbs or guards around anchors to prevent impact and damage from area traffic.
2. Guy cables near ground level must be guarded and made visible to prevent injuries.

Incorrect attachment of guying cables to elevator or lateral bracing from an
adjoining structure will result in support failure, collapse of the elevator and death
or severe injury to anyone in the area.
Attach guying cables to the elevator only by means of the 4 wire bolt-on brackets
as shown in
. If bracing from an adjoining structure is used, attach only at
flange joints between legging sections.
