JIB ERECTING AND STOWING PROCEDURE
General Warnings
NOTE:
Tag line used in these procedures is to control the
movement of the jib.
Preparing the Crane for Jib Erection
Procedure
Requirements for Jib Erection
Before you erect a lattice extension or the jib, the following
requirements must be met:
-
The swingaway lattice extension is mounted on the
side of the main boom and is in transport condition.
-
The crane is supported by the outriggers according
to the
lifting capacity chart
for the planned operation
with the lattice extension and is aligned horizontally.
-
The main boom is completely retracted and has
been lowered into horizontal position.
-
If the crane is equipped with two hoists with
additional equipment, the hook block is unreeved on
the hoist which is not used for working with the
lattice extension.
Requirements for Stowing the Jib
Before you lower a lattice extension or the jib into a
horizontal position, the following requirements must be met:
-
No other load is raised apart from the hook block.
-
The counterweight required according to the
lifting
capacity chart
for the planned operation with the
lattice extension is rigged.
-
The crane is supported with the outriggers
prescribed for operation with the erected lattice
extension according to the
lifting capacity chart
.
-
The main boom is fully retracted.
Securing Lattice Extension with Tag Line (Rope)
The lattice extension may swing out on its own accord when
the jib is removed from its stowage brackets.
You must therefore secure the lattice extension before you
begin with the erection procedure.
Secure the lattice extension as follows:
•
Attach a tag line (rope) at the front of the lattice
extension.
•
Guide the tag line (rope) underneath the lattice
extension, via the holding rod on the main boom and
back again.
•
Secure the other end of the tag line (rope) on the
crane (for example, on the steps of the access
l a d d e r t o t h e c a r r i e r o r t o t h e h o l e i n t h e
superstructure). Leave enough play in the tag line
(rope) that it is tight only when you swing the lattice
extension towards the main boom head later on.

PROCEDURE.
Erecting Procedure
10.1 m (33 ft) Jib
1.
Visually check to ensure all pins are installed.
WARNING
To prevent serious injury or death, always wear personal
protective equipment; that is, 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
the extension.
WARNING
Always secure the lattice extension with a tag line (rope)
on the main boom before removing any connections. This
will prevent the lattice extension from slipping off the run-
up rail, swinging around and knocking you off the carrier
or injuring other persons in the swing range.
DANGER
To prevent serious injury or death, do not stand on
decking until extensions are secure.
