Abstract: A safety device applied to appliances for lifting boards onto ceilings and walls comprises a telescopic mast, an upper part of which accommodates the board holder and traction and safety ropes operated by a manually controlled winch, a component for attaching and fastening the traction rope and safety rope so that they are at the same fastening level, and a mechanism for tensioning the safety rope. The attachment component is fixed in the lower receiving part of the terminal inner section of the telescopic assembly. The tensioning mechanism is external relative to the telescopic mast and situated facing the winch for winding the traction and safety ropes.

Abstract: A limit stop support device for fitting variable-width plasterboards upon appliances for lifting and handling such boards comprises a one-piece receiving support which fulfils various adjustable-position sliding functions along a holder arm of the board holder or panel holder. The support receives a board or panel limit stop which is retractable in opposition to elastic return element(s) located on the receiving support, and a unit which fulfills a dual function of locking the receiving support in position on the arm and limiting the travel of the limit stop in opposition to the elastic return element(s) in an operating phase in order to place boards and panels on a ceiling and/or wall.

Abstract: A materials handling and lifting appliance for a board or panel holder comprises, on a mast, telescopic elements controlled by a winch, and a device for articulating the board or panel holder articulatedly mounted on a shaft relative to a structure connected to the upper end of the telescopic elements at the upper end of the mast. The articulating device includes a support base shaped and designed to accommodate tilting of the holder into a horizontal, intermediate or vertical position. The board holder or panel holder is designed with a carrying arm, the length of which can be adjusted depending on the dimensions of the boards or panels to be picked up and positioned. The carrying arm includes handlebars fitted with control handles and mechanisms for controlling locking and unlocking of the articulating device. The handlebars facilitate tilting the board holder or panel holder into horizontal, intermediate or vertical positions.

Abstract: The device comprises combinations of two subsets of guide packings. Each combination has a profile matching an upper internal and lower external profile of each a respective telescopic profiled element, forms a one-piece nipple, and comprises an internal and external surround for cooperating with upper and lower front end edges, respectively in the internal cavity of the respective telescopic profiled element for upper guidance and on the exterior of the respective telescopic profiled element for lower guidance, Each packing has a surround with slots. Each slot receives a stud hinged and joined to the surround to be incorporated and positioned by elastic deformation in an opposing opening. Around these slots receiving studs, a zone is arranged for supporting and guiding another telescopic profiled element.

Abstract: An orientation device for a holder of a sheet material or for a holder of a panel of material, for a lifting and handling apparatus, of the type comprising an upper end of an upright of the apparatus receiving a horizontal fixed support profiled section for the framework of the sheet holder or panel holder, the framework being mounted so as to be articulated relative to said support profiled section, is noteworthy in that the horizontal fixed support profiled section is offset relative to the upright and receives, at its end, an articulation rod of a sheet- or panel-support device. The latter device comprises a support base with a planar upper wall serving as support and fastening to the framework, and extending via two plates that are parallel and perpendicular to the planar upper wall. The plates are arranged with two curved, oblong apertures, allowing the passage of an indexing and locking means.
