Crane Capacity
36,000 pounds at a five feet load radius.
Maximum Tip Height
48' height
Control Console
Dual operator stations equipped with four single axis levers for the
main crane controls with independent controls for all outriggers for precise leveling.
The levers for the outriggers and stabilizers are offset and shorter than the main crane
control levers for added safety. Each side includes a bubble level gauge, engine start/stop
switch, signal horn button, variable speed foot throttle, lifting capacity chart, range
diagram chart, and boom angle indicator. A system pressure gauge is located on the
driver’s side console.
Boom
Three-section fully proportional, high strength steel plated rectangular tube
sections. A maximum boom tip height of 48 feet mounted on a truck. The boom nose
contains two lower main sheaves and one idler sheave for three-part line. Assembly
includes heavy-duty cylinder fittings, pivot pins, and replaceable wear pads.
Winch
Mounted at the base of the boom for a long fleet angle and flat level spooling
of cable. Winch is driven by planetary reducer and powered by a hydraulic motor. Burstof-
speed winch provides increased line speed. The winch brake is spring applied, pressure
release design. Supplied with 275 feet of 9/16" diameter wire rope with a single-line wire
rope pull of 9,600 pounds, and a down-haul ball with swivel hook for single part line.
Load Moment Limiter (LML) System
LML System senses hoist cylinder pressures,
boom length and boom angle with hydraulic function lockout. The display console
is equipped with an integrated bar graph showing crane utilization, boom angle or
boom length, a mode select controls for main boom and jib operation, and a radio
anti-two block with an audio / visual warning and shut-off functions to limit hookboom
point contact. The display console can be positioned at both operator stations.
Outriggers
A-frame link type outriggers for a minimum of 20’-10” extended span. Additional stabilization provided by rear under frame mounted stabilizers.
Frame
Full length, all welded rigid 4-plate design sub-frame for a 20’ bed that bolts
to the truck frame under the pedestal.
Turret
Turret is one-piece weldment. Turret rotates on large diameter ball bearing.
Rotation
Hydraulic motor drives turret through double reduction planetary swing
drive for 372 degree non-continuous rotation. The swing drive system has a spring
applied, pressure release brake.
Boom Extension
4-1/2" external cylinder with 3-5/8” rod extends the largest telescopic
boom section. The top boom section extends with wire rope.
Lift
One double-acting 7" full displacement, long stroke cylinders provide smooth and
stable boom elevation. Holding valve prevent boom from lowering in event of hose failure.
Cylinders
All cylinders use microhoned cylinder tubing, chrome shafts, top grade
packing and protective rod wipers. Cylinder-mounted holding valves provided on all
load-holding cylinders.
Hoses
All high pressure hose is wire braid reinforced with a minimum safety
factor of 4 to 1.
Oil Tank Capacity
70 gallon mounted to truck frame on roadside.
Hydraulic System
Equipped with cable-shift PTO, gear type 3-section pump, SAE Oring
face seals on pressure lines, a 10 micron return line filter and a shut-off ball valve.
The control valve distributes all flow to obtain a 39 gpm for the hoist system, 9 gpm
to the swing circuit and 23 gpm for the other crane functions. System is parallel open
center type, and the operating pressure is approximately 3,000 PSI.
Cab Equipment
PTO cable and switch with indicator light installed in truck cab. U/L
approved 5:BC dry chemical fire extinguisher installed in truck cab.
Operator Manual
One copy of operation, maintenance, safety and parts manual
provided with each unit.
Installation
Unit installed on customer's truck, painted, system and tank filled with
oil, tested, inspected, certified and ready to operate.
Standard Paint
Paint BoomTruck white, outriggers red, and bed and boxes black.
Bumper
Bureau of Motor Carrier Safety rear bumper.
Weight
Approximately 16,500 lbs. with 20' steel-floor bed less truck.
Truck Chassis Requirements
Approximately 180" to 192” C.A. RBM 1,463,000 inlb.
per rail, 20,000 lb. front axle and 54,000 lb. GVWR required. Trucks must have
extended rear frame, increased cooling, heavy-duty front and rear springs, 12V electrical
system with high capacity alternator, cab clearance stop/tail/backup lights, and I.D.
lamps.
Additional equipment to consider
front tow hook, mud and snow
tires for off highway use. Recommended GVWR is minimum for BoomTruck with
flatbed only. Contact factory when additional equipment is to be added. **
** Chassis specification applies to configuration with boom stowed forward over chassis cab. |
