Abstract (en)
The device has rigid lifting elements e.g. rods, connected by its base to a point spaced from a load e.g. formwork device (1A). A connection unit for connecting each lifting element to the point is utilized to allow inclination of one of the lifting element toward the other lifting element in a vertical plane defined by the point. The connection unit comprises leaf springs provided with a spring leaf utilized to bend the leaf springs with respect to each other. An independent claim is also included for a formwork device assembly comprising formwork devices whose upper edges are connected by lifting devices.
Abstract (fr)
Dispositif de soulèvement d'une charge (1A) en deux points espacés de cette charge, comprenant, pour chacun desdits points, un organe rigide de soulèvement (16, 17) relié par sa base audit point, les moyens de liaison de chaque organe rigide audit point étant adaptés pour permettre une inclinaison dudit organe de soulèvement vers l'autre desdits points dans le plan vertical défini par les deux points. Lesdits moyens de liaison comprennent un ressort à lame(s) (24) comportant au moins une lame de ressort adaptée pour fléchir vers l'autre desdits points. Application au soulèvement de paires de dispositifs de coffrage de béton.
