ERECTING AND STOWING THE BOOM
EXTENSION

General Warnings

DANGER
To prevent serious injury or death, always wear personal
protective equipment; i.e., a hard hat, eye protection,
gloves and metatarsal boots.
Boom angles are used to control speed at which
extensions swing during erecting and stowage. Improper
boom angles will cause uncontrollable swing speeds of
extension.
NOTE: Tag line used in these procedures is to control the
movement of the boom extension.
DANGER
Before attempting to erect or stow the boom extension;
read and strictly adhere to all danger decals installed on
the boom/boom nose, boom extension, and stowage
brackets.
Securing the Boom Extension with Tag Line (Rope)
NOTE: A tag line attached to the tip of the extension is
used to control the movement of the boom
extension.
GROVE
SET-UP AND INSTALLATION PROCEDURES
Wedge Socket
Always secure the boom extension with a tag line (rope)
on the main boom before removing any connections. This
will prevent the extension from swinging around and
knocking you off the carrier or injuring other persons in the
swing range.
The extension may swing out on its own accord when you
remove the last connection that held the extension at the
side of the main boom.
You must therefore secure the extension before you begin
the erection procedure.
Secure the boom extension as follows:
• Attach a tag line (rope) at the front of the extension.
• Have a helper hold the tag line (rope) tight while you
are removing the last connection.
NOTE: If you are alone, secure the other end of the tag line
(rope) on the crane (e.g., on the steps of the
access ladder or to the superstructure. Leave
enough play in the tag line that it is tight only when
you swing the extension towards the main boom
head later in the procedure.

Erecting

To prevent serious injury or death, do not stand on
decking until extensions are secure.
