Cab
The Full Vision cab on
the RT890E tilts up to
20˚providing the operator
additional comfort when
working at long boom and
extension lengths.
Boom
e RT890E is equipped with a 11,4 m - 43,2 m (38 ft - 142 ft)
ve-section, full power boom. e Grove MEGAFORM™ boom
shape eliminates weight and increases capacity compared to
conventional shapes.
Removable counterweight
Counterweight and auxiliary hoist is
hydraulically removed/installed for easier
hauling from job to job.
Power lung extension
For improved up-and-over reach, a power lung
extension is available on the RT890E and
hydraulically osets from the super-structure cab
from 50to 400.
CraneSTAR is an exclusive and innovative crane asset
management system that helps improve your profitability
and reduce costs by remotely monitoring critical crane data.

Load moment
and anti-two block system
Standard “Graphic Display” load moment and anti-two
block system with audio-visual warning and control
lever lockout. These systems provide electronic display
of boom angle, length, radius, tip height, relative load
moment, maximum permissible load, load indication
and warning of impending two-block condition. The
standard Work Area Definition System allows the
operator to pre-select and define safe working areas.
If the crane approaches the pre-set limits, audio-visual
warnings aid the operator in avoiding job-site
obstructions.

NOTE: ()Boom angles are in degrees. A6-829-103447
#LMI operating code. Refer to LMI manual for operating instructions.
*This capacity is based upon maximum boom angle.
NOTES:
1. All capacities above the bold line are based on structural
strength of boom extension and do not exceed 85% of
tipping loads, in accordance with SAE J-765.
2. The 33 ft extension length may be used with single
or double part line lifting service. The 56 ft extension
length may be used for single line lifting service only.
3. For main boom lengths less than 141.7ft with the boom
extension erected, the rated loads are determined by
boom angle. Use only the column which corresponds
to the boom extension length and offset for which the
machine is set up. For boom angles not shown, use
rating of the next lower boom angle.
4. WARNING: Operation of this machine with heavier
loads than the capacities listed is strictly prohibited.
Machine tipping with boom extension occurs rapidly
and without advance warning.
5. Boom angle is the angle above or below horizontal of
the longitudinal axis of the boom base section after
lifting rated load.
6. Capacities listed are with outriggers properly extended
and vertical jacks set only.
7. When lifting over the main boom nose with 33 ft or
56 ft extension erected, the outriggers must be fully
extended or 50% extended (17.3ft spread).

NOTES:
1. Capacities are in pounds and do not exceed 75% of tipping loads as determined by test in accordance with SAE J765.
2. Capacities are applicable to machines equipped with 29.5x25 (34 ply)General tires at 76 psi cold inflation pressure.
3. Capacities appearing above the bold line are based on structural strength and tipping should not be relied upon as a capacity
limitation.
4. Capacities are applicable only with machine on firm level surface.
5. On rubber lifting with boom extensions not permitted.
6. For pick and carry operation, boom must be centered over front of machine, mechanical swing lock engaged and load restrained from
swinging. When handling loads in the structural range with capacities close to maximum ratings, travel should be reduced to creep
speeds.
7. Axle lockouts must be functioning when lifting on rubber.
8. All lifting depends on proper tire inflation, capacity and condition. Capacities must be reduced for lower tire inflation pressures. See
lifting capacity chart for tire used. Damaged tires are hazardous to safe operation of crane.
9. Creep –not over 200 ft of movement in any 30 minute period and not exceeding 1mph.

#LMI operating code. Refer to LMI manual for operating instructions.
*This capacity is based upon maximum boom angle.
NOTES:
1. All capacities above the bold line are based on
structural strength of boom extension and do
not exceed 85% of tipping loads, in accordance
with SAE J-765.
2. The 33 ft luffing folding boom extension may be
used for single or double line lifting service. The
56 ft luffing folding boom extension may be
used for single line lifting service only.
WARNING: Lifting with the 33 ft extension
base, with the 23 ft extension fly either erected
or folded along side of extension base, is
strictly prohibited.
3. WARNING: Operation of this machine with
heavier loads than the capacities listed is
strictly prohibited. Machine tipping with boom
extension occurs rapidly and without advance
warning.
4. Boom angle is the angle above or below
horizontal of the longitudinal axis of the boom
base section after lifting rated load.
5. Capacities listed are with outriggers properly
extended and vertical jacks set only.
6. For main boom lengths less than 141.7ft with
the boom extension erected, the rated loads
are determined by boom angle. Use only
the column which corresponds to the boom
extension length and offset for which the
machine is set up. For boom angles not shown,
use rating of the next lower boom angle.
7. When lifting over the main boom nose with
33 ft or 56 ft extension erected, the outriggers
must be fully extended or 50% extended (17.3ft
spread).
