OEM-Loading and Unloading Vacuum Tube Crane Lifter Manually Controlled Pneumatic Manipulator
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.
