Ready to go: the GFT 8000 transmission unit series from Rexroth is quickly available and ready to install

Finely graduated and ready to install: the new HYDROTRAC GFT 8000 series with new sizes covers a wide range of applications for hydrostatic travel drives.

Integrated dynamic multiple-disk brake saves installation space and weight

The series production of all nine frame sizes for the new HYDROTRAC GFT 8000 transmission units has begun at Bosch Rexroth. The modular series combines two and three-stage planetary gearboxes with axial piston motors to create an individually customizable drive package for far-traveling mobile working machines. The GFT 8000s, which are available from stock, can be compactly installed in wheel, chain and roller-driven construction machines.

The new transmission units, which come in nine sizes, cover output torques from 10 to 130 kNm with their finely graduated gear ratios in both open and closed circuits. Using the numerous options, machine manufacturers can realize individually adapted drive solutions with highly available standard assembly groups. For example, the optional internal multiple-disk brake for sizes 8120, 8130 and 8150 meets the strict road approval safety requirements in Germany and the USA for speeds of up to 50 km/h. The low-maintenance, dynamic multiple-disk brake reduces the installation space required and reduces the weight by up to 75 percent in comparison to conventional mechanical brakes.

Through the combination of two and three-stage planetary gearboxes with the latest series of Rexroth fixed and variable motors, the drive units achieve around 10 percent more torque in comparison to the previous series. As a result, machine manufacturers can improve driving performance without the installation space changing or can use a smaller size whilst maintaining the same power. Thanks to the platform concept, the gearboxes can be installed in various vehicle designs. The ready-to-install drive units lower the expenses and time required for logistics and installation for heavy goods vehicles as well as for pavers, rollers and other mobile construction machines.

Economical, precise, safe, and energy efficient: drive and control technology from Bosch Rexroth moves machines and systems of any size. The company bundles global application experience in the market segments of Mobile Applications, Machinery Applications and Engineering, and Factory Automation to develop innovative components as well as tailored system solutions and services.

Intelligent hydraulics for increased availability

Connected hydraulics increase the availability of machinery and plants through condition monitoring and predictive maintenance. For this purpose, Rexroth offers scalable solutions, from individual units with local evaluation to the complete, cloud-based monitoring of large plants. Sensors measure all relevant operating conditions and software detects wear before it leads to failure. Retrofitting kits also economically integrate already installed plants into these concepts.

Linear motion, short time to market

Stand-alone linear axes are the trend. The combination of electrical drive unit and mechanical or hydraulic cylinder reduces installation space and engineering time and combines our specific professional knowledge in one system. With ready-to-mount and i4.0-enabled solution packages, Bosch Rexroth is in line with the current market requirements regarding electrification, digitalization and monitoring as well as condition-based maintenance. The uniform control and drive concept which is used in the different technologies serves as a basis for a short time to market and the economical implementation of hybrid solutions.
