Lifting Scales

Scales for the bridge crane type used in the metallurgical industry for weighing and dosing of liquid metal in the ladle crane.

Scales embedded in the cart main hoist, auxiliary hoist trolley (if valve casting) and consist of modules with load cells with a radio channel controller mounted on a trolley terminal with two radio channels: one provides communication with the controller, and the second with ground control point based PC.

Indication of weighing results produced on the display terminal type TVKS crane system, which is installed permanently in the cab of the crane, and three remote displays, displaying a lot of metal in the ladle, the mass of metal in the ingot and speed metal spill, respectively. Scoreboard mounted on the casting platform operator casting.

The measurement results are transmitted over the air in real time through a repeater on the RT PC that is installed in the desired location on the technology.

Scales consist of the following components:

Weighbridge embedded in the bridge crane trolley.

Strain gauges with the radio controller ICC, mounted on a trolley.

Terminal microprocessor with two radio modems (hereinafter TVKS), installed in the operator's cab of the crane. One of the radio modem provides communication with the controller, and the second with the PC installed at a distance of no more than 200 meters from the crane.

PT, installed next to the PC, which receives information from the terminal and sends it to the PC.

Four-digit seven-segment digital scoreboard indicating the weight bucket "gross" (TMB).

Four-digit seven-segment digital scoreboard indicating the mass of the ingot (TMS).

Three-digit seven-segment digital scoreboard indicating the casting speed (TSL).

The controller can receive signals from the weighbridge load cells, summarizes them and converts into a digital code that is transmitted over the air terminal.

The terminal receives the first radio signal from the controller and performs its digital processing, which resulted in the digital display terminal displays weight bucket "gross" bucket and current weight of the ingot. The terminal also stores information regarding the ingot made in the casting, and after casting transmits this information via radio channel to the second radio located outside the PC.

The terminal incorporates hardware and software necessary for the diagnosis, calibration, calibration and adjustment of the weighing system and install discrete value display information on indicators and external terminal board that are connected to it wired communication lines.

Radio modem in lifting scales converts received digital code from a radio to a standard interface, such as RS232, on which transmits the information to the PC.
