FEATURE DESCRIPTION
Boom9,6 m to 38,0 m five section full power boom. Maximum tip height 40,0 m.
Boom elevation1 cylinder with safety valve, boom angle from -2,7° to +82°.
Load moment and independent anti-two block systemLoad moment and independent anti-two block system with audio visual warning and control lever lock-out. These systems provide electronic display of boom angle, length, radius, tip height, relative load moment, maximum permissible load, load indication and warning of impending two-block condition with lock-out hoist function.
CabAluminium, tiltable (approx. 20°), full vision, safety glass, adjustable operator's seat with suspension, engine-independent heater. Armrest-integrated crane controls. Ergonomically arranged instrumentation and crane operating controls. Drive/steer controls.
SlewingAxial piston fixed displacement motor, planetary gear, service brake and holding brake.
Counterweight7,6 tonnes, consisting of various sections. Hydraulic removal system (from crane cab).
EngineSee carrier.
Hydraulic system2 separate pump circuits operating in an open circuit with 1 axial piston variable displacement pump (load sensing) and 1 geared constant delivery pump for slewing. Thermostatically controlled oil cooler. Tank capacity: 600 l.
Control systemFull electronic control of all crane movements using electrical control levers with automatic reset to zero. Integrated with the LMI and engine management system by CAN-BUS. ECOS system with graphic display.
HoistAxial piston motor with planetary gear and brake. Drum rotation indicator.
