Compact Milling Machine – VTM-compact

Compact. Adaptable. Powerful.
Simple and easy reprofiling of rails and turnouts on short-haul lines and in confined spaces

The VTM-compact milling machine corrects severe defects in rails and switches at hot-spots on light-rail and standard gauge tracks and in tunnels, removing up to 2 mm of metal per pass. Thanks to its compact dimensions and light weight, the VTM-compact is compatible with virtually every loading gauge and easy to transport. Although not self-propelled in transport mode, the machine is able to travel shorter distances on its own in operation mode (max. 4 km/h). VTM-compact can be set up to run on all the common track gauges to machine flange rails on either ballasted or slab track.

Highlights

VTM Milling Technology

The VTM-compact employs up-cut milling, i.e. the milling wheel rotates counter to the direction of travel. This immediately has several advantages. More milling power is transmitted, which increases efficiency and allows the machine to remove up to 2 mm of metal with each pass despite being so lightweight. VTM-compact also vibrates less and applies a significantly better milling finish to the rail surface. Its milling efficiency is enhanced still further by the rubber tires on the drive wheels. In All-Wheel-Drive mode, power is transmitted evenly to all four wheels, which gives the machine more forward propulsion without slippage.

Very Clean Procedure: no dust and no sparks

Like its „big sister“ VTM-performent, the VTM-compact is clean, safe and eco-friendly. VTM-compact doesn‘t use water, produce sparks or generate grinding dust, and in tunnels, for example, there‘s no clean-up required because the milling chips are extracted during the process and stored in the chip bunker for disposal.

Compact and Lightweight

At only 5.8 m long and around 2.2 m high and 2.2. m wide, VTM-compact fits inside almost all structure clearance gauges and can be used on the London Tube, for example. Its compact design and weight of just 16 tons – around half of other milling machines – make it very easy to transport. It fits into a standard container (TEU-compatible) and can be towed to a deployment location on a flat wagon or by truck. VTM-compact is on-railed and readied for operation in a matter of minutes and can also be optionally equipped with a hoist for even easier loading and unloading.

Efficient and Precise

VTM-compact reprofiles the rails or turnouts precisely and back to near new condition. The machine's special feature is a suspended milling spindle assembly that can variably alter the milling wheel tilt angle in order to machine inclined rails without a tool change.

The machine's performance is certainly impressive given its low weight. Removing up to 2 mm per pass, it is ideally suited to machining even the most severe rail damage. What's more, residual roughness and ripple are minimal and conform to the DB Ril 824, EU Standard 13231:3-2012. And if you want to get that visually perfect finish to the milled surface, VTM-compact can also be fitted with a grinding unit as a finishing module.

Flexible Operation and Control

The covered operator‘s console at the back of the vehicle is equipped with two 15-inch touch screens, a control panel and two camera monitors. The operator can also control the VTMcompact remotely by means of a practical wireless panel. This gives him access to all the machine‘s important functions and a good view of the track at the same time.
