including hook block/s and freely moveable with the nominal load
Standard anti-two block device, when activated, provides an audible warning to the crane operator and disengages all crane functions whose movement can cause two-blocking.
Operators Control Station
Frame mounted, open air style control station with cab shell includes all crane functions, driving controls, and overhead safety glass. Other standard equipment includes a durable weather resistant seat with seat belt, hourmeter, sight level bubble, and fire extinguisher. The dash panel includes engine oil pressure gauge, engine water temperature gauge, fuel gauge, transmission low oil and high temperature warning lights, low battery warning light, and brake system low pressure warning light. The LSI (load indicator) receiver is mounted to the top of the dash.
Operators Control Station Enclosed
Includes the standard cab shell with the addition of front, right and rear glass. Hinged full door with sliding glass. Front windshield wiper, heater and defroster are included.
Axle
Steer
Standard: 3-steering modes: Front 2-wheel, 4-wheel coordinated, and crab steer w/electronic self alignment. Rotary switch select on dash panel.
Brakes
Hydraulic actuated internal wet-disc service brakes acting on all four wheels. A dash mounted toggle switch activates the dry disc parking brake on the transmission output yoke with a dash warning light.
Suspension
Front: Rigid mounted to frame. Rear: Provides 3.5° oscillation for use on semi-rough terrain. Axle lock-out switch, on dash panel, to engage/disengage the axle lock-out. Axle lock-out must be engaged (locked) whenever picking on rubber and when traveling in the crab steer mode. A warning light indicates when the axle lock-outs are engaged.
Work
Load Indicator (wireless LSI)
A simple effective and easy to use load indicating system used in conjunction with the anti-two block system to assist the operator in efficient operation of the unit within the limits of the load chart. The display panel displays the hook load and warns the operator when a preset load capacity is exceeded. The warning is by a flashing light on the display panel. In conjunction with the load display panel (receiver), there is a wireless transmitter and load sensing pin attached to the boom head that transmits the hook load to the display panel.
Rated Capacity Limiter (wireless RCL)
Similar to the Load Indicator, but stops the telescope out and boom lift down function when a load limit is exceeded. Uses a similar display panel with the addition of displaying boom angle and 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 on load chart. Displays color coded light bar and audible alarm with function cutoff if load exceeds entered parameters.
Engine
Fuel Tank Capacity
50 gallon (189 L) steel construction with steel side plate to guard against side impact. Fuel gauge located on dash panel in operators station.
Hydraulic
Outriggers
2-stage hydraulic telescoping beam with vertical jack at the four corners provides extended and down and retracted and down lifting capacities. Integral holding valves on both beam and jack.
