Boom
e 33,52 m (110 ft) four-section boom is the longest in its size
range. e longer boom allows the operator to perform more
lifts without the use of a jib, reducing setup time and improving
eciency. A 30,48 m (100 ft) four-section boom is also available.
Graphical Rated Capacity Limiter (RCL)
e Graphical Rated Capacity Limiter (RCL) is standard on all
Series NBT30H-2 machines. e RCL system displays all crane
load lifting values simultaneously while providing real-time
information about the crane and truck operating system and
includes work area denition system (WADS) and operating
limits. e RCL is also weather resistant and visible in full or low
light. Includes on-board diagnostics of all electronics allows for
ease of service.
Dual side control station
Traditional mechanical control levers and layout with modern
features and benets located on both sides of the crane. Ecient
load-sensing hydraulic system allows for optimum multi-
functioning from the crane and integration of the optional
radio remote controls providing the operator greater exibility.
Automotive switches and wiring, and electric over hydraulic
outrigger control pendant allows for optimum performance
and control. Electronic engine start/stop switches with foot
pedal throttle control at each side. e RCL graphical display is
mounted to a rotating arm for use at either control station.
Outriggers
Two sets of “HO”- style outriggers allow operation in multiple
congurations with 6 m (20 ft) full-span, a 4,2 m (14 ft)
mid-span setting, and a fully retracted outrigger spread. Main
outriggers are equipped with removable ball and socket polymeric
foot pads. Independent control of each outrigger beam and jack
cylinder using a tethered pendant control for optimum setup
visibility and includes a level indicator (sight bubble).

Mounting configurations
The mounting configuration is based on an 85% stability factor. If the bare truck weight requirements are not met,
counterweight will be required. The complete unit must be installed on the truck in accordance with factory requirements.
Since individual truck chassis vary, a test must be performed on the unit to verify actual stability after mounting and installing
counterweight (if required). A summary of mounting and truck requirements are:
For 180° working area –
Gross Axle Weight Rating Front (GAWR) – 8165 kg (18,000 lb)
Gross Axle Weight Rating Rear (GAWR) – 15 455 kg (34,000 lb)
Gross Vehicle Weight Rating (GVW) – 23 587 kg (52,000 lb)
Wheelbase (WB) – 256 in (6,50 m)
Cab to Axle Trunnion (CT) – 4,88 m (192 in)
After Frame (AF) – 2,67 m (105 in)
Frame Section Modulus (SM) from outrigger to
RSOD – 327 cm3(20 in3) and 759 MPa (110,000 psi) material
Bare Chassis Weight for stability prior to installation.
Front: 4513 kg (9950 lb)
Rear: 4105 kg (9050 lb)
For 360° working area –
Optional Single Front Stabilizer (SFO)
Gross Axle Weight Rating Front (GAWR) – 8165 kg (18,000 lb)
Gross Axle Weight Rating Rear (GAWR) – 15 455 kg (34,000 lb)
Gross Vehicle Weight Rating (GVW) – 23 587 kg (52,000 lb )
Wheelbase (WB) – 256 in (6,50 m)
Cab to Axle Trunnion (CT) – 4,88 m (192 in)
After Frame (AF) – 2,67 m (105 in)
Frame Section Modulus (SM) from front spring hanger to end of
after frame – 492 cm3(30 in3) and 759 MPa (110,000 psi)
material
Bare Chassis Weight for stability prior to installation.
Front: 4513 kg (9950 lb)
Rear: 4105 kg (9050 lb)
For 360° stability the truck frame must have a 492 cm3(30 in3) section modulus [372 850 Nm (3,300,000 in-lb) RBM]
minimum under the crane frame, 295 cm3(18 in3) section modulus [223 710 Nm (1,980,000 in-lb) RBM] at the front spring
rear hanger, 197 cm3(12 in3) section modulus [149 140 Nm (1,320,000 in-lb) RBM] through the front spring and 49 cm3(3
in3) section modulus [37 284 Nm (330,000 in-lb) RBM] at the stabilizer attachment point on each truck frame rail.
Notes:
• Gross Vehicle Weight Rating (GVWR) is dependent on
all components of the vehicle (axles, tires, springs, fame,
etc.) meeting manufacturers’ recommendations; always
specify GVWR when purchasing trucks
• Diesel engines require a variable speed governor and
energize-to-run fuel solenoid for smooth crane
operation; electronic fuel injection is required
• All mounting data is based on a National Crane Series
NBT30H-2with subbase and an 85% stability factor
• e complete unit must be installed in accordance with
factory requirements, and a test performed to determine
actual stability and counterweight requirements; contact
the factory for details
• Transmission neutral safety interlock switch is required
• NBT30H-2(100 ft boom) with front center stabilizer
will be approximate 12,2m (40 ft) overall length.
NBT30H-2(110 ft boom) will exceed 12,2m (40 ft)

Boom extension capacity notes:
.  ft and  ft extension lengths may be used
for single line lifting service.
. Radii listed are for a fully extended boom with
the boom extension erected. For main boom
lengths less than fully extended,the rated
loads are determined by boom angle. For
boom angles not shown, use the rating of the
next lower boom angle.
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.
.Boom angle is the angle above or below
horizontal of the longitudinal axis of the boom
base section after lifting rated load.
.Capacities listed are with outriggers properly
extended and vertical jacks set.
. When lifting over the main boom nose with
 ft or  ft extension erected, the outriggers
must be fully extended or % extended  ft
