Superstructure
Boom3-section: 19 ft. 6 in. – 43 ft. 0 in. (5.9m – 13.1m) three-section fullpower boom.Maximum tip height: 51 ft. 8 in. (15.7m)
5-section : 19 ft. 6 in. – 67 ft. 0 in. (5.9m – 20.4m) five-section fullpower boom.Maximum tip height: 75 ft. 0 in. (22.8m)
Boom angle indicator mounted on both sides of base section.
*Boom Extension17 ft. (5.18m) fixed boom extension, offsettable to 30˚ and 60˚ viapivoting boom nose.Maximum tip height: 92 ft. 0 in. (28.0m)
Boom Nose2 sheave, 4-position (0˚, + 30˚˚, + 60˚˚, + 80˚) pivoting boom nose forminimizing head space requirements. Lowers head height 23.9in. (0.60m) when nose is pivoted fully forward.
Boom ElevationTwo double acting hydraulic cylinders with integral holdingvalve.Elevation: 0° to 80°
Anti-Two Block DeviceStandard anti-two block device, when activated, provides anaudible warning to the crane operator and disengages all cranefunctions whose movement can cause two-blocking.
Load Indicator (wireless LSI)A simple effective and easy to use load indicating system usedin conjunction with the anti-two block system to assist theoperator in efficient operation of the unit within the limits of theload chart. The display panel displays the hook load and warnsthe operator when a preset load capacity is exceeded. Thewarning is by a flashing light on the display panel. Inconjunction with the load display panel (receiver), there is awireless transmitter and load sensing pin attached to the boomhead that transmits the hook load to the display panel.
*Rated Capacity Limiter (wireless RCL)Similar to the Load Indicator, but stops the telescope out andboom lift down function when a load limit is exceeded. Uses asimilar display panel with the addition of displaying boom angleand boom length read outs on the panel.
*Load Moment Indicator (hardwired LMI)Digital display of boom angle, boom length, boom radius,capacity, and allows for operator input to set the limits based onload chart. Displays color coded light bar and audible alarmwith function cutout if load exceeds entered parameters.
Swing Ball bearing swing circle with 360° continuous rotation. Planetary swing.Maximum speed: 2.5 rpm
Hydraulic SystemVariable displacement piston pump and piggyback gear pump.
Combined flow: 74.0 gpm (280.0 Lpm)
Maximum system operating pressure: 3600 p.s.i.
Six section valve bank, chassis mounted, operated via dashmounted, pilot pressure hydraulic joysticks.
Return line filter with full flow by-pass protection and serviceindicator.
60.0 gallon (227 L) hydraulic reservoir with sight level gauge andsteel side plating to guard against side impact damage.
Hoist Specifications
Piston motor drive with spring applied / hyd. released brake.Two speed power up and down.
Maximum Single Line Pull: 13,800 lb. (6260kg)
Maximum Single Line Speed: 320 fpm (97.5m/min)
Maximum Permissible Single Line Pull: 11,000 lb (4990kg)(5/`8" [16.0mm] XIPS)
