Description

Cart for the transport of large loads

Object of the invention

The present invention relates to a cart for the transport of large loads, which provides considerable and essential novelty characteristics with respect to the elements similar known and used in the current state of the technique.

In general, the invention has developed a cart for the transport of large loads, which allows the easy sliding of the whole set, based on a platform that presents in its front zone the means of propulsion and address, while subsequently has means to expand its surface, through an extensible platform on which The rolling means are arranged.

More specifically, the cart for transport of large loads includes a fixed platform provided in its area previous means of propulsion and steering while subsequently it is telescopically coupled with a extensible platform, where the means of rolling

State of the art

Currently the handling and transportation of loads in internal spaces, warehouses, workshops and the like, are performs through platforms with insufficient rolling means when it comes to transporting large loads, such as loads of up to 40 tons.

Normally platforms are used whose media rolling, useful for small loads, cannot transport large loads, because the pressure exerted on the rolling means against the ground, does not allow easy advance of the platform and even on many occasions the impossibility of platform displacement.

Description of the invention

The present invention consists of a cart for the transport of large loads, which in general are It is constituted by a fixed platform, coupled posteriorly and telescopically with another extensible platform and that it has in its rear area the rolling means constituted by a large number of wheels on the same axle. Fixed platform it also has in its previous zone the coupling of the means of propulsion and steering.

All this will be explained in greater detail to what throughout the description that follows.

Brief description of the drawings

The description of the object of the invention is will be based on the accompanying drawings, in which title of example and without any limiting character therefore has represented one of the preferred embodiments of the present invention

In such commented drawings the which is related below.

The first figure represents a view in perspective of the cart for the transport of large loads object of the present invention, where the platform is observed fixed, on which the rear extendable platform is attached where are the rolling means while the means of propulsion and steering are arranged coupled to the front area of the aforementioned fixed platform.

Finally, the second figure represents the corresponding top plan view of the cart for the transport of large loads object of the present invention.

Detailed description of the preferred embodiment of the invention

The detailed description that follows from the preferred embodiment of the invention will be carried out taking as base the attached drawings, on which the corresponding parts or similar ones have been marked with the same numerical references to what along the two figures.

As can be seen according to the plans commented the cart for the transport of large object loads of the present invention, comprises a fixed platform (1), a extensible platform (2) with rolling means (3), in addition to a head (4) in the anterior area of the fixed platform (1), where provide the means of propulsion and steering.

The fixed platform (1) consists of two tubular side beams (5), rigidly joined by welding to a front crossbar (6), to another rear crossbar (7) and an intermediate crossbar (8), with all three remaining crossbars (6), (7) and (8), welded to a series of stringers Longitudinal (9).

The extensible platform (2) is constituted by two stringers (10) of equal section and slightly smaller contour than the internal section of the beams (5) of the fixed platform (1), whose stringers (10) are subsequently welded to a crossbar (11) carrier of the rolling means (3) while its ends above are included telescopically inside the beams sides (5) of the fixed platform (1).

The front crossbar (6) of the fixed platform (1) has a plate (12) with two lugs frontally attached (13) in the center of its front face. Between the two lugs (13) the head (4) is arranged, on which it is superiorly will provide conventional means of propulsion, while inferiorly it is rotatably coupled to a fork (14) axle block carrier (15) set address

The fork (14) of the head (4) is located also coupled to the steering means, which are constituted by a telescopic cylinder (16) attached to a side of the plate (12), while the free end of its stem (17) is attached to the fork (14).

The fixed platform (1) and the extensible platform (2) are related by a telescopic cylinder (18), centrally and longitudinally arranged between the crossbars intermediate (8) and later (7), to which the stem (19) crosses, whose free end is fixed between two lugs (20) arranged on the rear cross member (11) of the extensible platform (2).

The rear area of the crossbar (11) of the extendable platform (2), presents welded orthogonally and to equal distance from each other, a series of plates (21) between the that the wheel pairs (22) are arranged in transverse alignment, whose common axis crosses small plates (23) welded each of them to each plate (21).

In the internal areas of the posterior vertices of the extensible platform (2) and in the internal areas of the anterior vertices of the fixed platform (1), are arranged separately lifting cylinders (24).

Based on this constitution, we can adapt the length of the cart corresponding to the amplitude of the load to be transported, by means of the regulation between the fixed platforms (1) and extensible (2), by simply adjusting and manipulating the separation between them with the corresponding telescopic cylinder (18).

During cargo transportation, the address of the cart may be directed by manipulation by means Conventional Telescopic Cylinder (16), which will provide the different orientations to the fork (14) carrying the steering wheels (15).

The four cylinders (24) arranged in the zones internal to the vertices of the cart, will provide the means of elevation of the whole set, when this operation is necessary.

Conventional propulsion means and arranged on the head (4), they are generally constituted by a combustion engine, the hydraulic, the pump, the filters, hydraulic and fuel tank, brake and distributor, from where all the maneuvers are performed, giving all the corresponding propulsion to a gear that transmits in motion to the axle of the steering wheels (15).

All means of steering, propulsion and Lifting are done using the remote controls corresponding.

The arrangement of the series of wheel pairs (22) in transverse alignment located in the rear area of the cart, allows to perfectly support the load without the pressure of the same prevents the sliding of the assembly with the load included.

It is not considered necessary to make the content of the present description so that an expert in the matter can understand its scope and carry out the realization practice of the described object and object of the present invention.

However and since in the foregoing only one preferred embodiment of the object of the invention, it is evident that within its essentiality multiple variations may be introduced, without implying any alteration of the invention. Such modifications may especially affect the shape and dimensions of the object and material used and the types of lifting devices, propulsion and steering used for sliding the cart object of the present invention, its essential points being which are reflected in the following claims.
