FR2598399A1 - Self-stable and removable device for fixing a bracket crane onto elevating platforms. - Google Patents

Abstract

Removable device for fixing bracket cranes and lifting arms, which is provided with devices for locking on the platform 1, 2, 9, 10 and with telescopic feet 4, 5, 7, 8 making the assembly self-stable.

Description

Removable and freestanding bracket fixing device
lifting on lifting platforms
French patent application No. 8501035 for edge fitting equipment
of paving stones, etc. provides a jib detachably mounted on the deck
forklifts, without going into detail
In practice, assembly and disassembly needs to be developed to
that no help or physical strength of people, nor mechanical is
necessary for these operations.

The present innovation aims to make these operations easy by creating
a removable fastening device for lift aprons, capable of
receive on the one hand lifting jibs and on the other hand fitted with feet
preferably telescopic, in the folded position between the forks
in the folded position and in the unfolded position during disassembly making
the freestanding assembly. The fixing on the apron can be specific
with a single machine, or adjustable to be adaptable to all aprons
elevators.

Figure 1 a non-limiting example of a device in which (1) are hooks Attaching to the deck (2) are compensating thickness clamps (3) is a receiver of round, square or arbitrary stem. The gallows can
also be part of the system.

(4) are tubes forming a vertical upright and guide to the tube (5) (5) are tubes sliding vertically in the tubes 4) (6) are locking pins between the tubes (4) and (5) (7) are horizontal tubes fixed perpendicular to the tube (5) (8) is a sliding tube in the tube (6) (9) is the clamping part of the sliding apron in an adjustment light (11) (10) is the locking means in height of the room9) (11) is the height adjustment light.

Figure 2 shows the device in the self-supporting position, the lifting arm resting on the ground and the feet in the unfolded position, both vertical and horizontal.

The operating mode is simple: starting from the self-stabilizing position in FIG. 2, the elevator advances, places its horizontal bars under the hooks (5).

The operator traps with the hook (9) which he maintains in the locked position by the locking means (10) o
By the clamping means (2) the operator compensates for the difference in tool thickness that could exist between the different types of horizontal bars.

It remains to return the tubes (5) and (8) and lock them in the working position. In this way, the folded dimensions of the device are such that it can be placed between the forks of the elevator without hampering the work.

For disassembly, the elevator keeps the forks at the appropriate height, the operator unfolds the 2 telescopic feet which come to be placed lower than the forks, the lifting arm is lowered to place it on the ground, which gives the 3 points of self-stability.

it remains to undo the blockages and the elevator is released.

as for the lifting arm with its device, it remains in position, freestanding, to be instantly reassembled.
