Brevini’s slewing drives are an essential component in keeping weight and size to a minimum on equipment such as tower cranes, wind turbines, aerial platforms, discharge booms and excavation and construction equipment.
Their planetary structure means that they can withstand very high torque values while maintaining reduced dimensions, reduced weight and high efficiency. The wide range of ratios available enables the selection of a motor size and type which best suits users requirements: hydraulic, electric, pneumatic.Simple mounting, operating reliability and versatility make these units suitable for the most severe duties and environments.
Brevini produces the slewing drives also in gearmotor version, with integrated hydraulic motor and brake, specifically designed for mini-excavators and light duty machines. |

WHEEL DRIVES
Compact planetary wheel drives, designed for a wide range of self propelled vehicles with hydraulic transmission and individually motorised wheel drives.
They allow design engineers to simplify the project of mobile equipment, improving the price / performance ratio. The wide range of ratios available makes it possible to adapt the reduction unit to the most suitable hydraulic transmission. A manual release is provided, to disconnect the reduction unit from the motor for emergency towing. The versatility of this range of Brevini products is assured by a wide choice of braking systems (drum brakes, negative acting multiple disc, failsafe parking brake).
TRACK DRIVES
Compact planetary track drive units designed for use on tracked vehicles. This range of gearboxes has high strength structure, short overall length, very high radial and axial load capability. All the gearboxes are provided with integral multidisc failsafe brake and allow the direct mounting of hydraulic motors at the gearbox input.Due to the high torque rating and the quality of the materials, these units are the best solution in heavy duty applications.
Brevini produces the track drives also in gearmotor version, with integrated hydraulic motors. |

EPICYCLIC GEARS
Seven models. Three types.
That you need reducing transmissions, articulated or with caterpillar, the epicyclic gears Funk will give you whole satisfaction in terms of longevity, performances and design. They are proposed with various ratios of reduction gearing and the simple and multiple combinations of differential gears of center section involving energy through the device of exit according to the application.
Differential gear reductions
The epicyclic gears Funk are generally used on the conveyers, cranes, caterpillars, general purpose excavators, road rollers, tracked vehicles, winches, like on all types of machines intended for agriculture, construction, industry, the navy, the mining extraction and oil industry. |

The PPG precision planetary gear is characterized by three major design advantages:
PPG load compensation ensures minimized friction for smooth running and for outstandingly high synchronizing, and last but not least, a long service life.
The PPG compensating coupling has a unique, space-saving angle error compensation feature. The low mass moment of inertia ensures high motive response. The coupling operates without backlash, with high rigidity and has length compensation.
The friction optimized PPG seals ensure a lower starting inertie.
The thermal load limit is very high due to low friction losses.
Applications:
- Gantry robots
- Positioning systems for robots
- Automating production
- Manufacturing semiconductors
- Machine tools
- Loading/unloading machines
- Packaging machinery
- Woodworking
- Medical equipment
- CCTV
- Vending machines
- Measuring machines |

In applications where it is necessary to ensure proper alignment between a gearbox and a driven shaft, Brevini's in-line and right angle shaft mounted planetary gearboxes provide the ideal solution.
The ability of the compact and efficient shaft mounted gearboxes, not only to provide alignment between shafts, but also their flexibility of use and the fact that no machining is required to mount them to frames, are all major factors in their widespread use across all industry sectors. Complementing these user benefits is the flexibility offered by two different types of shaft configurations: hollow shaft for shrink disc connection or keyed cylindrical female shaft (FP type). |
