Crane Weighing System

Project Description:
Weighing System, integrated into the mixer cranes, transpose steel net weight to the process control system. Most important of this weighing system is new principle of load cells.

We developed a weighing system with Radial Force Sensors DRA. The Radial Force System has specific load cell geometry perfectly adapted to the typical design of large spreader beams in the steel industry. Electrical signals to the all load cells is suming on sumator box and after that transmits with SIWAREX U modul. SIWAREX U module is part of PLC SIMATIC S7-300 optimal solution for the measurement of crane loads. For process visualization and control weighing system we used graphical operator panels on crane operator cabins. Operator panel were connected via PROFIBUS DP, ETHERNET and wireless system with L3 level. Data from weighing system are used on existing factory network.

Scope of Work:
  • Detailed Mechanical and Electrical Design
  • Equipment specification and procurement
  • Programming PLC / Control logic
  • Manufacturing
  • Start-up during Commissioning
  • Training of Production and Maintenance personnel
