Description

The invention relates to lifting devices, in particular to the mast construction lifts.

The purpose of the invention is to expand the operational capabilities of the elevator by reducing the vertical dimension of the load-carrying mechanism.

FIG. 1 shows a mounted lift, general view; in FIG. 2, view A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The construction hoist contains the mast 1 and the cargo carriage 2 moving along it. The cargo carriage 2 has a frame 3 adjoining the mast 1 and a vertical axis 4 fixed to the frame 3. On the vertical axis 4 a hinged-lever mechanism consisting of C -link 5 and link 6, interconnected by a common vertical axis 7, moreover, the free end of link 6 has a height greater than the height of link 5. In the initial position, the longitudinal axes of the links coincide.

At the free end of the link 6, there is an axis 8, on which a cargo platform 9 is hinged, housed above the link 5. Towing axis 8 is pivotally suspended by a traverse 10 for suspension of cargo or container.

The operation of the lift is as follows.

In the initial position, the cargo carriage 2 of the lift is located at the base of the mast 1. At the same time, the links are in the reduced position (see fig. 3), when their longitudinal axes coincide. In this position, the lift is loaded, the cargo is placed on the cargo platform 9 and the traverse 10, or on one of these devices. Then include a lifting mechanism and raise the carriage to the desired floor. The worker accepting the load on the floor tightens the pivoting mechanism for link 6 to the window opening, and the links 5 and 6 rotate around their vertical axes 4 and 7. Link 6 unfolds relative to link 5 in the horizontal plane. When you turn the links, the cargo area 9 or the traverse 10 together with the cargo is inserted inside the building.

Then the cargo area is unloaded. In the case of placing the cargo in limbo on the traverse, it is lowered onto the floor with the carriage moving down. After unloading, the worker turns the links of the mechanism to its original position, withdrawing the load-lifting mechanism from the building opening.

Claims (2)

A CONSTRUCTION LIFT containing a mast on which a carriage with a swivel is mounted with the possibility of vertical movement BUT relative to the mast and the hinge-lever load-carrying mechanism entering the window opening of the building, the links of which have different lengths, characterized in that, in order to expand the operational capabilities of the lift by reducing the vertical dimension of the load-carrying mechanism, its links are located in one plane, and the long link is made C -shaped with the possibility of reaching a short link along its length, while the height of the free end of the short link is greater than the height of the long link. · zi. 1167137 one 1167137 2
