The construction industry is undergoing a significant evolution, resulting in the need for high degrees of flexibility and rapid development cycles. ZF is addressing these challenges at EXCON India in Bengaluru (BIEC, December 12-16) where the company (Hall 1, Booth F121) will demonstrate its expertise in driveline technology and intelligent system solutions that contribute to low or zero emissions and offer increased productivity at construction sites.
Electric Drive Solutions
ZF’s newly developed eTRAC electric drive system combines the performance and productivity found in traditional drivelines with important benefits that electric systems can offer. Thanks to its modular design, this new range of electric drives can easily be adapted for construction applications, providing:
- Zero emissions without compromising performance
- Low noise level
- Efficient electrical components
- Robust and reliable mechanical driveline
- Compact installation space
Electric compact loader
Compact vehicles such as loaders, site dumpers or telehandlers are the early adopters of e-mobility solutions for the construction equipment market, particularly in urban or emission-regulated areas. The eTRAC driveline system – with its range from 20-60 kW continuous power and for 48/96/650-volt e-motors (above) – provides the necessary zero-emission drive required for these vehicles.
ZF is a full system supplier, providing both the electric drive as well as a combination of front and rear axles, inverters and an eDCU (Electric Drive Control Unit). This best-in-class solution achieves the same output as conventional drivetrains, without compromising traction and end speed performance.
ZF’s newly launched eCD (electric Central Drive) system for backhoe loaders consists of a two-speed powershift transmission with integrated parking brake, electric motor, and inverter. To meet increasing customer demand, ZF also offers the ePTO to operate the working hydraulics.
The system can also be optionally adjusted with an axle disconnection. The system can be scaled up to peak torque 850 Nm and continuous power of 80 kW. Three power classes of ZF’s electric central drive system - eCD50, eCD70 and eCD90 (above) - are available to cover different vehicle sizes for targeted applications. The electric central drives can easily be adapted for various vehicle applications including mobile excavators, telehandlers, or forestry equipment.
To complete the range of electric drives for larger construction vehicles, ZF is offering the eTRAC eCD110-210 series for mid-sized wheel loaders, consisting of an electro-mechanical powershift transmission as well as one e-motor for traction and ePTO. An electric drive control unit for overall system performance and power management completes the system. With a 650 V operating voltage, the system can be scaled up to 120 kW continuous power while the ePTO ranges from 30 to 70 kW continuous power (Fig.3_electric midsized wheel loader). Thanks to its modular design, the system can be integrated into additional vehicle applications and can be driven independently from the power source. The company´s solutions can be adapted for both battery-electric vehicles and fuel-cell battery electric vehicles, which will also play a significant role in the future of construction equipment.
A global leader in hydraulic and electrohydraulic braking systems, ZF supports customers in the heavy duty, off-highway, construction, mining, and agriculture sectors with safe and efficient brake technology.
The company’s newest brake-by-wire solution (pictured above) is an important step change, as it provides vehicle manufacturers the ability to control deceleration via an electronic signal that adjusts brake pressure when needed, removing the need for hydraulic lines in the cab and evolving towards remote and autonomous operation.
The system is comprised of three components: an electronic pedal, electrohydraulic brake valve and a universal controller. Together, the system offers vehicle manufacturers ease of installation, electrohydraulic brake valves for precision brake control and adaptable pedal response/brake feel that can be customized to fit a vehicle’s brand identity. It also provides key operator benefits including reduced cabin noise, and passenger car-like comfort for brake feel.
Intelligent and innovative system solutions for logistics
Increasing just-in-time production, the rising number of online orders as well as longer and longer routes of transport are only some of the actual drivers in the logistics industry. Therefore, not only fast but also efficient and safe goods transport becomes more and more important. Another aspect to be mentioned is the reduction of danger potential for employees.
In doing so ZF provides intelligent mechanical systems for IC forklifts and electric forklifts and underlines once more its capability as technological leader with system competence.
Intelligent mechanical systems for electric forklifts
Whether zero-emission and quietly operating electric forklifts for usage in buildings or diesel forklifts who must transport high loads for a long distance outside. The technology therefore comes from ZF. For both applications ZF offers a large product range.
As this year's Excon India, ZF has introduced an innovation from the well-known eTRAC series for electric forklifts. The model range of the dual-motor front wheel drive eTRAC GP25 was extended by a Heavy-Duty version (pictured below).
Besides the advantages concerning energy efficiency, noise and maintenance intervals which distinguishes the eTRAC GP range in general, ZF offers with its Heavy-Duty version solutions for even larger forklifts. In comparison to classic eTRAC GP25 which is designed for a max. wheel load by 2 tons or tire size of 18 inches, eTRAC GP27 (Fig.6_ZF eTRAC GP27) can be applied in forklifts with maximum 2.5 tons wheel load or tyre size of 21 inches. This is enabled by even more solid wheel bearings as well as a reinforced housing.
