POSIVEL PV, is generally realized with hook.  If necessary it can be equipped with simple gripping tools to allow the handling of light loads in a weightless condition in any direction. The particular double arm structure and medium joint makes it easy to handle and precise throughout the working area.
A pneumatic cylinder fed with compressed-air, combined with a transmission cables 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.
