BOOM EXTENSIONS
Refer to Figure 6-73 for a diagram of the boom extensions
available for this crane.
The TMS9000-2 can be used with the following boom
extensions:
• 35 ft to 58 ft (10.5 m to 17.7 m) manual offsettable bi-fold
swingaway boom extension (folding manual luffing
extension), with mechanical offset mechanism for
offsets of 0, 20, & 45 degrees, as standard—unless it
was explicitly not ordered.
• 35 ft to 58 ft (10.5 m to 17.7 m) hydraulic offsettable bi-
fold swingaway boom extension (folding hydraulic luffing
extension), with hydraulic offset mechanism for offsets
of 0 to 45 degrees.
• 11.4 ft (3.5 m) heavy duty two-sheave manual offsettable
boom extension (heavy duty extension), with manual
offset mechanism for offsets of 0, 20 and 45 degrees.
• 11.4 ft (3.5 m) heavy duty two-sheave hydraulic
offsettable boom extension (heavy duty extension), with
hydraulic offset mechanism for offsets of 0 to 45
degrees.
• 26 ft. (8 m) base extension insert (26 ft insert) to use with
any of the 36 ft. to 59 ft. (11 m to 18 m) folding
extensions.
All boom extensions are built specifically for the crane with
which they were sold. Each extension is stamped with the
crane’s serial number.
To use a single boom extension on several Grove cranes,
contact Manitowoc Crane Care or your authorized Grove
Distributor.
DANGER
To prevent serious injury or death, always wear personal
protective equipment; i.e., a hard hat, eye protection,
gloves and metatarsal boots.
CAUTION
Equipment Damage Hazard!
Operate the crane only with extensions which have the
same serial number as the crane, to prevent malfunctions
and damage to the equipment.
