Introduction to the 700TK Series: the union between 700T and Kayaba

The Bonfiglioli 700TK Series represents a specific and high-performance solution for the slew drive control of earthmoving machinery. It is important to emphasize that the 700TK series gearmotors are technically 700T series gearboxes equipped with a Kayaba hydraulic motor.

Choosing the 700TK Series means opting for a successful solution that combines the robustness of Bonfiglioli planetary gearing with the extreme precision of Kayaba hydraulic motors. This synergy is designed to ensure smooth turret movements and unparalleled structural resistance.

This series is the number 1 choice for those requiring a reliable “plug & play” transmission, capable of managing the heavy stresses typical of excavation and lifting operations.

Valuable technical features of the 700TK range

The value of the 700TK Series lies in the perfect integration between the gearbox and the motor. The mechanical foundation is the renowned 700T gearbox, known for its reinforced output support capable of accommodating large-sized pinions.

The addition of the Kayaba motor elevates hydraulic performance, offering an extremely prompt response to commands and excellent torque modulation.

Here are the main technical features:

• Integrated Kayaba Motor: High-pressure axial piston motors for constant rotation.

• 700T Series Mechanics: Multi-stage planetary gearbox designed for extreme radial loads.

• Integral Output Pinion: Designed to mesh directly onto the slewing ring with maximum precision.

• Multi-disc Brake: Integrated hydraulic-release parking brake to safely lock rotation.

Effectiveness of the Bonfiglioli-Kayaba technical partnership

The use of this series is extremely effective in tracked excavators. The combination of the 700T series and the Kayaba motor ensures that heat generated during hydraulic braking phases is correctly dissipated.

The 700TK Series is a success factor for manufacturers who wish to reduce assembly times by receiving a complete unit, already tested to operate at high pressures.

Relying on the 700TK Series guarantees a reduction in hydraulic failures, as Kayaba motors are famous for their wear resistance even in the presence of frantic duty cycles and continuous direction reversals.

Compact design for turret installation

The design of the 700TK Series is optimized for vertical footprint. Despite the power of the 700T gearbox group and the efficiency of the Kayaba motor, the unit remains slender, facilitating mounting within the excavator structure.

FP Trasmissioni supports the integration of these slew drives by analyzing the hydraulic specifications of the machine to ensure a perfect coupling with the main pumps.

Advantages of the 700TK Series design include:

1. Bearing Robustness: Designed to withstand the thrusts deriving from the output pinion.

2. Advanced Seals: Labyrinth systems to protect the gearbox from dust and mud.

3. Facilitated Maintenance: Drain points and oil level checks positioned for quick access.

Ideal applications for the 700TK Series

The 700TK Series is considered the number 1 solution for the rotation of tracked machines in difficult operating contexts.

Main applications include:

• Tracked Excavators: For the integral slew control of the upper part of the vehicle.

• Hydraulic Drill Rigs: Where millimetric arm positioning is required.

• Mobile Cranes: To ensure load rotation without oscillations or jerks.

• Demolition Machines: Where vibrations transmitted to the turret are high.

The adoption of this valuable technology transforms machine management, offering the operator total control and the owner a vehicle with low operating costs.
