SET-UP AND INSTALLATION
Installing the 16 ft (4.9 m) Sections The securing pins (1) for the connection are secured with retaining pins in the holders at the foot of the 16 ft (4.9 m) sections (Figure 4-81).
BOOM EXTENSION INSERTS (ADDITIONAL EQUIPMENT) Identification The boom extension consists of the 56 ft (17.1 m) bi-fold swingaway lattice extension and two boom extension sections. The boom extension is designed for the crane it was delivered with. The parts which belong to the crane have the same serial number as the crane.
•
Using an auxiliary crane with sling, lift the 16 ft (4.9 m) section with support roller on an auxiliary crane and lift it in front of the main boom head so that the bearing points (2) and (3) align on both sides.
•
Insert the securing pins into the bearing points (2) and (3) on both sides.
•
Secure all pins with retaining pins.

•
Install the second 16 ft (4.9 m) section in front of the first 16 ft section for the 89 ft (27.1 m) boom extension in the same way.
All parts of the 56 ft (17.1 m) bi-fold swingaway lattice extension.
-
Both sections of the boom extension 16 ft (4.9 m) inserts.
•
Install 56 ft (17.1 m) section in front of the respective 16 ft (4.9 m) section per previous instructions in this section.
The following sections are identified by the serial number:
CAUTION Operate the crane only with those sections of the boom extension which have the same serial number as the crane. This prevents malfunctions and damage. NOTE:
For technical reasons a crane may only be set with one boom extension.
If you wish to use the boom extension on several Manitowoc cranes, the parts of the boom extension must be adjusted for these cranes and labeled with all of the respective serial numbers.

Slinging Points
Removing the 16 ft (4.9 m) Sections •
Using an auxiliary crane with sling, lift the 16 ft (4.9 m) section until the bearing points (2) and (3) are relieved.
•
Release the pins and knock them out of the bearing points (2) and (3) on both sides.
•
Insert the pins into the holders at the foot of the 16 ft (4.9 m) sections and secure them with retaining clips.
CAUTION This section shows the slinging points of the 16 ft (4.9 m) sections. Attach the sections only to these slinging points because they will then automatically have the correct center of gravity. Use only lifting gear with sufficient load bearing capacity. The 16 ft (4.9 m) sections have two slinging points (Figure 4-82)—one slightly offset on each side. NOTE:
Grove
For electrical connections at the 16 ft (4.9 m) sections, refer to Electrical Connections at the Boom Extension, in this section.
