Wirtgen introduces trio of compact cold milling machines
7 Feb 2022
New W 100 Fi, W 120 Fi and W 130 Fi compact models offer all technologies of company’s larger machines for cost-efficient work in confined and compact spaces in urban areas
Wirtgen has launched a trio of high performance, next generation one-metre class compact milling machines which the manufacturer says are unique in the industry segment and integrate the proven technologies of its F-series large milling machines.
The W 100 Fi, W 120 Fi and W 130 Fi cold milling machine, which have been launched in the European market, are front loaders with working widths of 1m, 1.2m and 1.3m respectively. All three are powered by a Stage V John Deere diesel engine with a rated output of 360hp, which Wirtgen and John Deere have jointly tuned to offer torque characteristic that meet the specific needs of the cold milling process, said a statement from Wirtgen.
It added that as a result of the tuning, the machines use “significantly less fuel”, while delivering high productivity and milling to a maximum depth of 330mm. Wirtgen said customers can look forward to the same high performance in the new compact machines as they have experienced in the company’s large milling machines with onboard digital assistance systems Mill Assist machine control, Wirtgen Performance Tracker (WPT) and the Level Pro Active levelling system.
In automatic mode, Mill Assist selects the operating strategy with the most favourable balance between milling performance and operating costs. This increases milling performance and simultaneously reduces fuel, water and pick consumption and CO2 emissions. The operator can also pre-select one of three alternative operating strategies: ‘ECO’, ‘Performance-optimised’ or ‘Milling pattern quality’. This makes it possible, for example, to pre-define the required milling pattern quality on a scale from 1 (coarse) to 10 (very fine) at the press of a button, explained Wirtgen in its statement.
Mill Assist also automatically controls the drive system, the company adds, and iIn conjunction with the diesel engine, a very broad spectrum of applications can be realised by reducing or increasing the milling drum speed. The low-speed range enables reductions in fuel consumption and minimises pick wear. In the upper speed range, a high-quality milling pattern can be achieved, even in the case of higher area performance rates.
The manufacturer added that the Wirtgen Performance Tracker automatically determines area performance rates, milling volumes and the fuel and water consumption of the machine – without any need for external surveyors on the construction site. The operator can view all important performance and consumption data in the cabin in real time and send an automatically generated report to the machine owner by email immediately after completion of the milling job. WPT is an optional feature that can also be retrofitted to already operational compact milling machines at any time, Wirtgen added.
“Compact dimensions and optimised machine weight for easy transportation predestine this trio of machines for a multitude of construction site scenarios. The highly manoeuvrable cold milling machines are particularly suitable for milling work where space is limited, for example in city centres or on car parks. As a result of their high productivity, they are also ideal for surface layer rehabilitation and complete pavement removal on smaller or medium-sized construction sites,” said Wirtgen’s statement.
“Thanks to the ability to quickly change the FCS milling drums with different pick spacings and working widths, the compact milling machines from Wirtgen can also be rapidly reconfigured on-site to adapt to changing applications.”
The new operator’s cabin in the machines is characterised by comfort, ergonomically designed control elements, a premium look and feel and modern design, added Wirtgen. Overviews of all relevant working areas familiar to users of Wirtgen milling machines is provided by the slender wasp waist of the machines and up to five cameras. A new five-inch control screen in the multifunctional armrest displays all machine-relevant information.
“Another smart solution is the convenient access to the milling machine at the rear that automatically adjusts to the machine height. This means that machine operators have ergonomic access to the operator's cabin in all working scenarios,” the statement added.
