Wirtgen W 55 HR overview

Wirtgen W 55 HR features overview

Hydraulic Machine Height Adjustment with Two Speed Settings

The new feature on the left-hand control console enables easy or highly precise adjustment of the machine height to the current working situation.


Large Ground Clearance

Ample ground clearance not only prevents the machine from being damaged by obstacles but also enables difficult maneuvers, such as reversing in the milled cut or loading the machine on a flatbed truck.


Fast and Easy to Assemble and Disassemble

A special coupling device enables the loading conveyor to be attached or removed in a few swift steps by only one person. This increases the flexibility of the machine.


Flexible Loading Regardless of the Job Situation

The loading conveyor is adjustable both laterally and in height, thus allowing the material to be loaded even in difficult job situations.


Extremely Compact Machine Design

The machine’s compact design not only enables quick turning and maneuvering on site but also facilitates machine transport.


Engine

Internally-Developed Rapid Slope Cross-Slope Sensor (Optional)

The internally-developed, electronic Rapid Slope cross-slope sensor ensures that the cross-slope profile is extremely precise. The cross-slope sensor makes it possible to work significantly faster while maintaining the same leveling quality.


Individually Hydraulically Lifting Side Plates

Individually hydraulically lifting side plates provide effective closure of the milling chamber on both sides of the machine.


Powerful Diesel Engine

The machine’s high engine output at optimum torque guarantees rapid and powerful operation regardless of the milling depth.


Loading Conveyor

High-Performance Rear Loader for Professional Milling Operations

The extremely powerful half-meter cold milling machine features an efficient, modern operating concept at a working width of 0.5 m. Easy-to-use additional and automatic functions increase the machine’s performance potential to quickly complete any milling job. The modern LEVEL PRO PLUS leveling system fully integrated into the machine control system guarantees high-precision milling results. The machine can be equipped with a large number of different milling drums, increasing flexibility and machine utilization. The high-performance rear loading system can be flexibly adjusted for optimum loading of the milled material.


New Level Pro Plus Leveling System

Level Pro Plus stands out due to its extremely precise milling results. The leveling system especially developed for cold milling machines is fully integrated into the machine control system, enabling a high degree of automation.


Additional Camera System

The camera system consists of one camera and a heavy-duty monitor. The monitor provides a high-resolution view of the loading situation from the camera at the end of the discharge conveyor.


New Operating Concept with Automatic Functions

The innovative operating concept includes many automatic and additional functions, e.g. the water pump with automatic on / off function. The concept not only increases operator performance but also the productivity of the small milling machine.


Proven Milling Drum Design

Toolholders with an increased wear path enable an extremely long lifespan while additional tools in the peripheral area of the milling drum produce clean milling edges.


High Capacity Conveyor

The 400 mm wide loading conveyor (optional) is provided with a rugged cleat profile to ensure effective material transport.


Automatic Load Control System

The electronic load limit controller integrated into the machine control system keeps the machine constantly in the optimally high milling performance range.


Three Different Milling Drum Speeds

Milling drum speed one is selected for low diesel and cutting tool consumption, milling drum speed two for maximum milling performance, and milling drum speed three for the best milling surface quality.


Adjustable Amount of Water

The amount of water injected, which can be adjusted as required, ensures economical water consumption in every application.


Special Milling Contour

Milling drums with a variety of tool spacings or working widths can be replaced in a short amount of time for maximum use of range and high machine capacity utilization.


Maneuverability

Pivotable Rear Right Support Wheel for Flush-to-Curb Milling

The rear right support wheel can be pivoted in front of the milling drum mechanically to allow flush-to-curb milling.
