2 Dimensions Basic machine with undercarriage narrow track width Operating weight The operating weight includes the basic machine with crawlers, 2 main winches 120 kn including wire ropes (260 m and 495 m) and 20 m main boom, consisting of A frame, boom foot (10 m), boom head (7 m), boom extension (3 m), 81 t basic counterweight, 36 t carbody counterweight and 250 t hook block. Total weight Ground pressure approx. 210 t Ground bearing pressure 1.16 kg/cm 2 Equipment Main boom (No xx) max. length 86 m High reach boom (No xx and 1916.xx) 117 m Luffing jib (No xx) max. length 95 m Max. combination main boom 53 m and luffing jib 95 m Fixed jib (No xx) 11 m 26 m Auxiliary jib 36 t capacity Remarks 1. The lifting capacities stated are valid for lifting operation only (corresponding with crane classification according to F.E.M , crane group A1). 2. Crane standing on firm, horizontal ground. 3. The weight of the lifting device (hoisting ropes, hook block, shackle etc.) must be deducted form the gross lifting capacity to obtain a net lifting value. 4. Additional equipment on boom (e.g. boom walkways, auxiliary jib) must be deducted to get the net lifting capacity. 5. For max. wind speed please refer to lift chart in operator s cab or manual. 6. Working radii are measured from center of swing and under load. 7. The lifting capacities are valid for 360 degrees of swing. 8. Calculation of stability under load is based on DIN / part 2 / chart 1 and ISO 4305 Table 1 + 2, tipping angle The structures are calculated according to F.E.M (EN ; EN ). 2 LR 1200 SX

6 Technical description Engine Power rating according to ISO 9249, 270 kw (362 hp) at 2000 rpm Engine type Liebherr D 936 L A6 Fuel tank 800 l capacity with continuous level indicator and reserve warning Engine complies with NRMM exhaust certification EPA / CARB Tier 3 and 97/68 EC Stage III. Hydraulic system A double axial displacement pump supplies the open loop hydraulic system, allowing all functions to be operated simultaneously. To minimize peak pressure an automatic working pressure cut off is integrated in the pump. All filters are electronically monitored. The use of synthetic environmentally friendly (biodegradable) oils is possible. Working pressure max. 350 bar Oil tank capacity 650 l Main winches Line pull (1st layer) max. 175 kn Line pull (7th layer) 120 kn Rope diameter 26 mm Drum diameter 580 mm Rope speed m/min Rope capacity in 7 layers 489 m The winches are outstanding in their compact design and easy assembly. Propulsion is via a planetary gearbox in an oil bath. Load support by the hydraulic system; additional safety factor provided by a spring loaded, multi disc holding brake. The main winches use pressure controlled, variable flow hydraulic motors. This system features sensors that automatically adjust oil flow to provide max. winch speed depending on load. Option winch with freefall system: Clutch and braking functions on the freefall system are provided by a compact designed, low wear and maintenance-free multi disc brake. Crawlers Propulsion through axial piston motor, hydraulically released spring loaded multi disc brake, crawler tracks, hydraulic chain tensioning device. Track pads 1200 mm Drive speed km/h Luffing jib winch Line pull max. 105 kn Rope diameter 20 mm Jib luffing 51 sec. from 15 to 78 Boom winch Line pull max. 217 kn Rope diameter 24 mm Boom up 130 sec. from 15 to 86 Control The control system developed and manufactured by Liebherr is designed to withstand extreme environmental conditions such as temperature, vibration and electromagnetic interference and to meet all requirements that are needed in heavy duty crane operation. Complete machine operating data are shown on a high resolution display. Standard operational information is displayed by means of graphical symbols, fault indications are displayed in plain text (more than 15 languages available). The cranes are equipped with proportional control for all main movements, which can be carried out simultaneously. The crane is operated with 2 multi directional joysticks, the right for winch I and boom, the left for winch II and swing control. Option: Bi directional double T levers for simultaneous boom and luffing jib operation. The crawlers are activated by the two foot pedals. Additionally, hand levers can be attached to the pedals. Remote control for assembly of counterweight and boom hinge pins. Swing Consists of rollerbearing with external teeth, swing drive with fixed axial piston hydraulic motor, spring loaded and hydraulically released multi disc holding brake, planetary gearbox and pinion. Both swing modes are possible speed control or free swing. A multi disc holding brake acts automatically at zero swing motion. Swing speed from 0 3 rpm continuously variable. Noise emission Noise emissions correspond with 2000/14/EC directive on noise emission by equipment used outdoors. 6 LR 1200 SX
