Boom Rest – Heavy-duty fabrication. Easily removed to
simplify loading and unloading truck deck.
Control System
Dual operator platforms are equipped with four single-lever
crane controls arranged to ANSI B30.5 standards. Fully
proportional control valves and system pressure gauge. Each
station also includes outrigger and stabilizer controls,
engine start/stop, foot throttle, signal horn, boom-angle
indicator, bubble levels, load chart and range diagram.
Hydraulics
Hydraulic System – A 3-section vane pump direct-
mounted to power take-off on truck transmission provides
42 gpm (159 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. 100-gallon (379-liter)
baffled reservoir includes suction ball valve with strainer
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 – Senses boom hoist cylinder
pressure, boom length and boom angle. Audio-visual
warning indicated 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.
Anti-Two-Block System – Audible warning and shutoff
functions prevent hook from contacting boom point.
Back-Up Alarm – Supplied on factory-mounted cranes,
electronic audible motion alarm activated when truck
transmission is in reverse gear.
General
Electrical – State-of-the-art, weather-resistant components
throughout. Automotive style electrical system for easy
Upperworks
Boom
Booms – Inverted T-cross section, 4-or 5-section
telescoping type, extended and retracted proportionally by
a double-acting hydraulic cylinder and cable-crowd system.

sheaves mounted on heavy-duty roller bearings. Two
removable pin-type rope guards.
Boom Elevation – Double-acting hydraulic cylinder.
Working range from 10˚ below horizontal to 80˚ above.
Load Hook – 5-ton (4,5 mton) capacity hook with heavy-
duty swivel and weight is provided for single-line operation.

by hydraulic motor. Maximum theoretical swing speed
1.5 rpm. Wet multi-disk internal brake is spring-
applied, pressure-released. Oversized diameter ball-
bearing swing circle with external gear. 372˚ non-
continuous rotation.
Outriggers
Out-and-down style outriggers, operated independently
for precise leveling. 22' 1 1/4" (6,8 m) spread at full
extension and 13' 4" (4,1 m) spread at intermediate
extension. 16" (406 mm) diameter floats. Bubble level
located near outrigger controls.
Mounting
Mounting
– Pedestal and subframe are mounted to
chassis by threaded rods and clamp plates. No welding,
drilling, or bolting to truck frame is required.
