ABSTRACT:
A telescopic crane for stores, in particular for cargo holds, designed for transportation and storage of loads placed in stacks or on racks, which consists of a two-girder bridge with the crane movably mounted thereon, and includes a crab with a rotary platform and a telescopic column with a clamp. The telescopic column has a mobile set of members slidable below or above a fixed member. The fixed member is slidably connected with the rotary platform in order that the fixed member may be lowered together with the other members to a level permitting the turning of the platform.
The end member of the column has a fork and a movable member forming a clamp, which is slidable along the end member by means of a tie system of guiding, which consists of a winch connected with the fixed member and of lifting and lowering ties wound through all members of the column.
In the case of an even number of members, during the movement of these members, the winch is coupled with a driving element for these members. In the case of an odd number of members, the winch is independent. The clamp is provided with a pulley block gear which clamps the load, and is equipped with a ratch that locks the clamp. The two-girder bridge has beams under the track which are of a special design.
