A hoist system having a drum primarily self-contained within a batten, for raising and lowering lighting, sound equipment, curtains and the like in a performance environment. The hoist system may be adapted with safety mechanisms including an overload sensor and/or a slack line detector. The system may be provided in the form of a point hoist. The compact system is highly scalable to a variety of spaces and applications, including school and public theaters and concert halls, as well as some homes, private business, etc. Additional features include various cable management systems and trim adjustment mechanisms for use with the hoist system.

A balancer for tools includes a rotating winding and unwinding drum for a cable, configured with a free end for supporting a tool. The balancer also includes a spring, wound around the main axis of rotation of the drum and integral with a terminal portion with the drum, in order to generate an elastic reaction, as a consequence of the unwinding of the cable and of the consequent rotation of the drum, adapted to facilitate the rewinding of the cable. The balancer further includes an element for braking the drum, which is adapted to generate a resisting moment which acts even indirectly on the drum to contrast the rewinding stroke of the cable; a respective electronic unit is furthermore associated with the element and is provided with a module for the control and adjustment of the intensity of the resisting moment generated by the element.
