A pneumatic cylinder fed with compressed-air, combined with a transmission lever system, provides balance to the load weight applied. The cylinder force is controlled through two pneumatic circuits purposely arranged: the first one always keeps the weight system balanced; the second one provides to always keep the weight load balanced. The operator can change the load level applying a minimum force on the gripping tool or directly on the load.
It allows a fast presetting of the load balancing effect in case of weight change.
It allows the lifting and handling of the load in a quick, precise and linear way, without any adjustment, simply actioning a lever control.
It allows the load balancing by actioning a pneumatic pushbutton after lifting the load through a lever control.
It allows the automatic load balancing without any adjustment, after having simply actioned the gripping through proper controls
