Wheel Profile Measuring System

Description

The wheel profile measuring equipment is divided into three separate systems:

  • Artificial Vision Wheelset Parameter Measuring Equipment (EVA): The parameters of all the wheels are measured while the train is running, automatically detecting any wheels that are out of tolerance. It is based on laser wheel illumination and special camera imaging.
  • Wheelset Surface Defect Detection System (DSR): Thanks to an advanced ultrasound detection system, it identifies and quantifies any instant deterioration that may have occurred during circulation on the surface of the tread band (cracks, wheelflats, dents, etc.)
  • Wheelset Eccentricity Measuring Equipment (EMO): This system measures irregular wear of the tire, that is to say, the lack of roundness. Throughout a complete turn of the wheel, the system monitors the roundness defects that occur on three wheelset circles (selected by the customer) by obtaining the wheel out of roundness value and the corresponding graph.

Dynamic Balancing Machine

description

The universal balancing machines are designed for accurate balancing of a wide spectrum of rotors. They are suitable for balancing cylindrical rotors with integral shaft journals and for balancing disc shaped rotors on balancing arbors.

Permanent calibration, ergonomic design and a logical operating sequence are features that facilitate operation.

Their modular design principle and a wide range of accessories make the machine highly flexible.

TECHNICAL CHARACTERISTICS

In addition to the above applications, test rotors are used for standardized testing in accordance with ISO 2953 (UMAR = minimum achievable residual unbalance) or SAE ARP4048.

Multiprocess Lathe

description

The multiprocess lathe with CNC is able to turn wheelsets, axles and wheel hubs, profiling them to the required dimensions.

It has a one-piece cast iron bed, thermally stabilized, and with chip removal section.

Four speed ranges and an automatic tool change allow the axle to be acted on from the turret. Lubrication is automatic and it is located on the cross carriage.

TECHNICAL CHARACTERISTICS

Distances between centers, up to 8 meters, with the possibility of being adapted to different requirements.

The tailstock center and its base are cast, reinforced with nerves. The movement is motorized along the bed and has a thermal expansion compensation system for the workpiece.

The operator and other workshop workers can work safely thanks to the front and rear guards of the lathe.

Bogie Testing Bench

description

Bogie testing presses are test benches for mounting, dismounting and testing of all types of bogies and their springs.

These machines can be configured as simple units, for mounting and dismounting operations only, to high-tech solutions, ideal for dealing with different track gauges and for measuring multiple parameters such as track gauge, axle parallelism, axle diagonal, wheel diameter, wheel distance and suspension shim calculation.

TECHNICAL CHARACTERISTICS

The bogie testing benches can be installed both in a pit and on standard industrial floor, depending on the specific needs of each customer.

Underfloor Wheel Lathe

DESCRIPTION

Underfloor wheel lathes are state-of-the-art machine tools designed for turning (reprofiling) railway wheels mounted on their axles and with their corresponding grease boxes. This way, the wheels can be turned, without having to be removed from the axles.

We have three main models of underfloor wheel lathes, which have been developed to service different types of trains and railway vehicles according to their maximum weight per axle. 

All models are configurable to all track gauges and different tread profiles depending on the customer’s needs.

TECHNICAL CHARACTERISTICS

The automated model allows the operator to turn a complete composition without the need to intervene in the process of train movement and wheel turning decision. These are some of the automated tasks:

  • Automatic motion of the composition
  • Measurement of the wheel profile before using the lathe
  • Turning of the wheel according to the pre-defined template

Press for Bogie Mounting/Dismounting

Descripción del equipo

This bogie press is used for mounting, dismounting, and checking bogies of all types. It can be installed in pit or on standard industrial floor, depending on the customer’s needs.

Two hydraulic cylinders, consisting of load cells, are installed on the upper beam.

TECHNICAL CHARACTERISTICS

Each cylinder, independently of each other, to exert its own force on the bogie, is fitted with a plate, previously fixed, which under pressure rests on the lower part of the mentioned beam, thus obtaining the reaction support.
