Exceptional Efficiency
The replacement of the NB700S slewing drive gearbox is particularly made for pinion and slewing ring drives. Productively used on tower cranes, shipboard and harbor cranes, wind turbines, and steering drives on ship propulsion systems, the planetary equipment device can be utilized in nearly all purposes where precise positioning is essential. These planetary slewing drives are appropriate for the most demanding responsibilities in any setting.

The layout of the gearbox optimizes torque overall performance and radial load ability in get to completely mesh the pinion and ring gear. For exact adjustment, some variations have eccentric mounting in between the pinion axis and the casing axis. Their vast selection of ratios enables the variety of motor size and kind which ideal satisfies the customer’s needs and software.

Crucial Characteristics
1. Output torque assortment: one thousand-180000 Nm
2. Equipment ratios: i=3.3-3000
3. Assist: slew assistance (with flange-mounted)
4. Output shaft: splined or with integral pinion output shafts supported by large-duty potential bearings
5. Relevant motors: axial piston hydraulic motors, hydraulic orbit motors, IEC electric powered motors
6. Hydraulic motor options: strain aid valve, over-middle valve, parking brake
7. Electric powered brake: DC and AC variety
8. Hydraulic brake: hydraulically introduced parking brake
