Abstract

Carriage perfected for lifting apparatus, characterized in that it comprises an anterior carriage and a posterior carriage rolling one in front of the other on the same path of the arrow, the posterior carriage comprising an upper rigging to which a lower rigging is suspended by a cable, at the same time that the previous carriage carries an upper rig to which a lower rig is suspended by the same cable, a single lifting cable circulating from the rear of the arrow, successively, on the upper rig of the posterior trolley, on the lower rigging of the rear carriage, again on the upper rigging of the rear carriage, then on the upper rigging of the anterior carriage and on the lower rigging of the anterior carriage, removable hooking means being provided, on the one hand, between the two carriages to solidarity them to each other, on the other hand between one of the cars and the arrow, on the other hand between the lower rig and the apart corresponding upper side, and finally between the two lower pieces, one of which has at least one fixing member for the load to be handled.
