Modernization of railway scales

Description

Our company carries out modernization of mechanical railway scales into electronic ones by replacing the mechanical lever system with load cells, and also priming the supporting foundations. As a result of the modernization, the client receives electronic scales with the maximum capacity of 150 tons, 50 kg resolution and all necessary functions in accordance with the requirements of “Ukrzalіznitsa.” Expert conclusions on the use of the existing platform and foundation provides the customer. Advantages of scales,  manufactured by “Technowagy”:

– the design of  load cells and their integration units ensures stable readings and high measurement accuracy;

– scales are adjusted using the extended readings of the weighing terminal – in the “kilogram” mode (d = 1 kg);

– scales can be calibrated independently in the presence of weighing;

– have the ability to determine the longitudinal and transverse displacement of the center of gravity of the railway carriadge;

scales  provide an opportunity of computer accounting, as well as the display of information on a computer display and / or printer.

  • Weighing
  • Tare weight compensation
  • RS 232

The function of the railroad carriadge mass centre determination displacement.  Also there is an overload signaling when  reaches max capacity + 9d. The TWP-25  manufactured by “Techwagy” in the stainless housing has the following features:

Automatic zeroing of the initial weight when the device is switched on (within 10% of weighing scale the permitted range)

Automatic zero correction while operation process (within the set range) to compensate for external influences (atmospheric precipitation, dust).

Mechanical tare (button) of current value weight within the limits of the maximum capacity.

Manual zeroing (by the button) of the current weight value within the maximum capacity.

Examining the total mass value.

Examining the mass values independently on each platform.

Examining the values ​​of the mass difference between the platforms.

Examining the values ​​of the transverse displacement of the mass in mm.

Reporting in case scales overload  (Max + 9Е).

Weighing through the RS-232 or 485 interface to the archiving computer (in the accounting system).

Possibility of installing filters to improve scales readings in accordance with the operating conditions.

Possibility of storing data on weighing in its own archiving device (option).

The ability to operate the device in dosing mode.

Protection class is  IP 65.

  • Scale
  • Manual instruction
  • User manual

The price includes:

– technical documentation for the manufacture of the foundation (we can build the foundation for an additional fee);

– delivery of platforms and equipment to the place of installation;

– installation of platforms and electronics;

– adjustment of scales;

– training the customer’s staff in using scales;

– standard computer program for weighing accounting.

In addition, our company can provide the following services:

Construction work of concrete foundations under the scales by our specialists, with building materials and special equipment.

Production of scales with simultaneous installation on wide and narrow (European) railway tracks.

The weighing process can be accompanied by video and photographic recording with recording of video and photo information in the database of weighted loads.

The scales software allows you to control and manage the traffic through the scales using barriers, traffic lights, remote displays and other light signaling equipment.

Additionally, support for the remote identification system of railway carriages can be integrated into the scales software.
