Cabin support frame anti overload weighing system for lifts and goods lift freight elevators.
The 942 sensor measures the load in the cabin by measuring the deformation (flexion) of the metal structure on which it is installed.
The 942 Strain Link sensor is suitable for new lifts and for modernization, it is an Italian product with a patented technology, it is cheap and reliable. It is possible to install the sensor on the beams (T or I or C profiles) typical of old systems that need to be modernized or on bent sheet structures typical of modern installations. Typical installation locations are cabin support structures, rope fastening structures in the shaft or cabin, winch support, pulley supporting structures (on the lift cabin or on fixed sheaves), regardless of the lift’s roping. S2Tech can recommend special spacers that have been designed to emphasize the mechanical phenomenon if the structure on which the sensor is to be installed is particularly rigid and provided little signal variation for the applied load.
The 942 sensors can also be used on industrial machines to indirectly measure the loads/forces applied by the machine, should they not be detectable directly because of the high loads. They are used, for example, in high-tonnage presses, plastic injection machines, bending presses, load control on hoists or cranes, on vehicles in order to avoid overturning (possibly matching the load measurement with that of the inclination).
In combination with the 699Plus weight controller, it is possible to monitor the weight in the cab, detecting possible anomalies compared to the expected weight range of the system, resulting in activation of relays connected to the intervention thresholds freely defined by the installer. The 942 sensor comes complete with the necessary screws for its correct installation on the metallic structure involved. In order to support manufacturers of plant systems in defining the optimal positioning of the sensor on the structure, S2Tech srl is ready to analyze the structure involved with FEM simulation in conjunction with the Technical Office of the Plant’s Manufacturer.
