The stay rods absorb side forces up to the maximum value specified in the weighing module's operating manual. To avoid damage, this maximum value must in no case be exceeded. If this cannot be guaranteed, additional protective measures need to be taken. Furthermore, it is essential to note that the stay rods cannot absorb any lateral forces.
The most favorable configuration needs to be identified already before installing the modules on site. It is essential to take into account individual circumstances, for example, wind loads, the tank volume, side forces, dilatation and thermal influences already during the design. On the one hand, the direction of the stay rods needs, without exception, to conduct all occurring loads through the stay rods while maintaining permissible limit values, on the other hand, temperature dilatation which may exert significant force must not be impeded. The mounting directions suggested by HBM can only provide approximate figures. The configuration of the weighing modules needs to be checked and matched to comply with static, dynamic and thermal loads for each project individually.
Note: When a tank is supported by four points (four modules), one support should be designed without any restraint by a stay rod (Fig. 5) to avoid restricting compensating movements and to avoid damage to the modules.
