SWING SYSTEM
Continuous rotation, free swing system assists in tandem lifting and
centering of boom over loads. Externally mounted, double-reduction planetary
gearbox driven by hydraulic motor. Equipped with a dual brake system;
spring-applied hydraulically-released Parking Brake and a foot actuated Dynamic
Service brake. Ball-bearing swing circle with external gear.
OUTRIGGERS
Out-and-down style outriggers, operated independently for precise
leveling. Fully extended, intermediate extension and fully retracted outrigger
beam positions. Bubble levels located in operator cab and near outrigger manual
controls.
Maximum outrigger spread 23 3 (7,1 m),
Intermediate outrigger spread 15 5 (4,7 m), 22 (559 mm) diameter floats.
Front Bumper Stabilizer - Single
stabilizer assembly mounted at the front of the truck (required); maximum float
load is controlled by preset counterbalance valve to prevent overloading the
stabilizer. This feature requires truck front frame extensions, consult factory.
MOUNTING
Lower frame is mounted to chassis by threaded rods and clamp plates.
No welding, drilling, or bolting to truck frame is required.
Lower Frame Torsionally resistant,
rigid 4-plate design with integrated outriggers and pedestal.
Rear Underride Protection Standard on
factory-mounted cranes. Fabricated structure mounted under rear of crane.
Complies with Bureau Motor Carrier Safety Standard 393.86.
Boom Rest Heavy-duty fabrication.
Easily removed to simplify loading and unloading truck deck.
CONTROL SYSTEM
Single cab enclosed operator platform and seat mounted to turret.
Four pilot operated single-axis crane controls provide precise metering and
multifunction capability; winch control fitted with hoist drum rotation
indicator (HDRI). Controls are arranged in accordance with ANSI B30.5
standards.
The operator station also includes engine start/stop, air foot throttle, signal
horn, load moment indicator display, view of boom angle indicator, load chart,
range diagram and the Manitex ACCUSwing control that allows the operator to
adjust swing speed up to a maximum of 2.0 rpm.
CAB
Standard features include a diesel heater, top hatch with electric
wiper and locking latches, front electric two-speed wiper, spray washer, fuse
block, operator cooling fan, dome light, slider side and rear windows, two
position side door with keyed outside latch. Cab may be upgraded to include a
hydraulic air conditioning unit.
HYDRAULICS
Hydraulic System A 3-section pump direct-mounted to power
take-off on truck transmission provides 41.7 gpm (158 lpm) to the hoist, 28 gpm
(106 lpm) to the boom hoist and telescope circuit, and 12 gpm (45 lpm) to the
swing and outrigger circuit. 115-gallon (435-liter) baffled reservoir includes
suction ball valve with strainer and two 25-micron filters in the return line.
Use of SAE O-ring and face seal O-ring hydraulic fittings throughout system.
Hydraulic Cylinders All load-holding
cylinders are equipped with integral holding valves.
WARNING SYSTEMS
Load Moment Indicator CANbus interface system maximize
expansion capabilities. Senses boom hoist cylinder pressure, boom
length and boom angle. Audio-visual warning indicates overload
conditions and overload shutoff feature prevents continuing
overload. Operator can access all relative crane configuration and
load conditions via display at the operator station. For added
reliability, the LMI system features an internal boom length sensing
cable.
Radio Anti-Two-Block System Audible warning and shutoff
functions prevent hook from contacting boom point. Switch is potted
to ensure reliability.
Back-Up Alarm Supplied on factory-mounted cranes,
electronic audible motion alarm activated when truck transmission is
in reverse gear.
