Lifting Limit Switch on the Lattice Extension
The functions raise hoist, extend main boom and lower main
boom are monitored during operation with the lattice
extension by the lifting switch on the lattice extension and
are switched off when the lifting limit switch is actuated.
NOTE: The same lifting limit switch is used for lattice
extension and main boom.
Overriding Connection on Main Boom
For operation with the lattice extension you must remove the
lifting limit switch on the main boom and override the
connection.
• Insert the short-circuit plug (1) in the socket for the
connection of the lifting limit switch Figure 4-47.
The connection is now overridden.
On 10 m (33 ft) swingaway lattice extension
• Attach the lifting limit switch (3) in the holder (4) and
secure it with a retaining pin. See Figure 4-47.
• Remove the short-circuit plug (2) from the socket (1).
• Connect the lifting limit switch on the socket (1).
• When unrigging you must insert the short-circuit plug (2)
back in the socket (1).
On the 17 m (56 ft) Two-Stage Swingaway Lattice
Extension
NOTE: For operation with the 17 m (56 ft) two-stage
swingaway lattice extension the connection for the
lifting limit switch on the 10 m (33 ft) section must
be overridden with a short-circuit plug.
• Attach the lifting limit switch (2) on the shackle (1) and
secure it with a retaining pin, Figure 4-48.
• Connect the lifting limit switch on the socket (3).
• When stowing, close the socket (3) with the protective
cap.
Folding Out/In the Deflection Sheaves on the
10 m (33 ft) Section
To prevent the hoist rope dragging on the main boom or
lattice extension during operation with the lattice extension
or jib, the hoist rope is guided via deflection sheaves.
