Liebherr has gearbox uprated the motor-reducer nominal capacity gearbox of its nine axle 750 tonne LTM1750-9.1 gearbox to motor-reducer an 800 tonner, gearbox although it will retain is motor-reducer 1750-9.1 gearbox nomenclature motor-reducer.
The company gearbox says that motor-reducer the upgrade gearbox has been made possible by the use of gearbox refined static calculation methods. The changes have gearbox also allowed it to improve motor-reducer lifting capacities across almost the entire working motor-reducer range. Owners of the motor-reducer LTM motor-reducer 1750-9.1 motor-reducer will be gearbox able to update their gearbox crane software with the gearbox new load charts, while the new gearbox jib system can also be retrofitted to gearbox existing slewing bearing units motor-reducer.
The slewing bearing company is also introducing a slewing bearing new luffing jib configuration using existing lattice sections to slewing bearing provide additional slewing bearing capacity increases slewing bearing for slewing bearing wind power slewing bearing applications slewing bearing. The slewing bearing changes allow the crane to lift 79.8 slewing bearing tonnes on a 28 metre jib to a hub slewing bearing height of 90 metres, a 10.7 tonne improvement, slewing bearing slewing bearing while it handle 65.6 tonnes slewing bearing on a 38.5 metre slewing bearing luffing jib at slewing bearing a hub height of 100 metres and a 24 metre slewing bearing radius – an 11.5 slewing bearing tonne increase over the old slewing bearing configuration.
A company statement explained the rationale slewing drive behind the capacity upgrade as follows: slewing drive“wide-ranging slewing drive experience of our design and slewing drive structural slewing drive engineers have with thin walled boom profiles slewing bearing has enabled the slewing drive popular slewing bearing calculation slewing drive models and approaches of the Finite Element method to be further refined. Supported slewing bearing by high performance computers, the real load bearing structure of slewing drive the crane is slewing drive simulated even slewing bearing better slewing drive in the static slewing bearing calculation model. Liebherr slewing bearing has now transferred the latest findings and methods,slewing bearing which had already slewing drive been applied in the new LTM slewing drive 1650-8.1.”
“Thanks slewing drive to the new slewing bearing luffing fly jib slewing drive configuration, the LTM 1750-9.1 has moved into slewing drive a higher load capacity class in the area of wind power slewing drive slewing bearing applications. So, for slewing bearing example, slewing bearing more than slewing bearing 10 tonnes of additional load slewing drive capacity slewing bearing can be generated for slewing drive the mounting of wind turbines slewing drive on 90 and slewing bearing 100 metre high towers. The LTM 1750-9.1 is also slewing bearing slewing drive much stronger in the area of heavy load lifting, such slewing bearing as the loading slewing drive of transformers onto ships, with slewing bearing typical working radii of 12 to 16 metres. The slewing bearing gain in load capacity in slewing bearing such applications is in slewing drive excess of slewing drive seven tonnes.”
Liebherr slewing bearing is also now slewing drive offering load charts for slewing drive safe operation in three slewing drive wind speeds.
