Introduction to 700C Series track drive gearboxes

The Bonfiglioli 700C Series track drive gearboxes represent technological excellence for the propulsion of tracked machinery. Designed to operate in the most extreme earthmoving conditions, these components are recognized by world-leading manufacturers for their robustness and reliability. Choosing the 700C Series means opting for a successful product that guarantees smooth and powerful traction in every operational situation.

This range of gearmotors has been developed to meet the needs of heavy machinery requiring high torque within extremely reduced overall dimensions. The 700C series track drive gearbox is not merely a mechanical component, but the heart of mobility for excavators, drilling rigs, and road paving machines.

Valuable technical features for the worksite

The true value of the 700C series track drive gearbox lies in its versatility and cutting-edge performance. The range is extremely comprehensive, offering tailored solutions for a wide variety of machinery.

Among the main technical and construction features present on the data sheet, we find:

• Wide torque range: The series offers 18 base sizes, covering output torques ranging from 1,000 Nm up to 625,000 Nm.

• Flexible reduction ratios: A wide choice of ratios to optimize speed and traction force.

• Integrated parking brakes: Equipped with negative-action oil-immersed multi-disc brakes (hydraulically released and spring-applied) mounted on the input side.

• Disengagement systems: Option for mechanical disengagement to allow vehicle towing in case of emergency.

Effectiveness on all types of terrain

The use of 700C Series track drive gearboxes proves particularly effective due to their capacity to withstand high radial and axial loads, typical of traveling on uneven or sloping ground. The gearbox housing design is extremely robust and engineered to be mounted directly inside the track structure, minimizing lateral dimensions.

Furthermore, compatibility with different types of hydraulic motors (axial piston or orbital) allows the travel system to be configured according to the specific hydraulic power available on the machine. This makes the 700C Series a successful component for both small mini-excavators and massive mining machinery.

Construction details and excellent materials

Bonfiglioli construction quality is reflected in every detail of the 700C Series. The planetary reductions utilize gears made of high-quality alloy steels, subjected to case-hardening and quenching heat treatments to ensure maximum surface hardness and wear resistance.

The bearings used to support the output are oversized to manage the stresses deriving from heavy-duty worksite use. Lubrication is oil-immersed, ensuring proper heat dissipation even during long machine transfers on roads or tracks. Each track drive gearbox is also equipped with “long-life” mechanical seals to prevent the ingress of dust, mud, and water, protecting the internal components.

Applications and sectors of use

700C Series track drive gearboxes find application in a wide range of machinery, including:

• Tracked excavators.

• Drilling and boring machines.

• Road pavers and milling machines.

• Tracked cranes and heavy lifting machinery.

• Mine-clearing vehicles and special defense vehicles.

Their reliability is such that many of these components are chosen for applications where safety and service continuity are critical parameters.
