SU1217975A1 - Method of driving above-norm loads over small artificial road structures - Google Patents

Description

The invention relates to a bridge-crossing technique and can be used to pass an over-standard load through small road artificial structures when transporting cargo on trailers of cargo containers.

The purpose of the invention is to simplify the operations of passing over-standard load through a small artificial structure while at the same time eliminating the need to use special structures of the unloading platform.

FIG. Figures 1–4 show the sequence of operations to pass an over-standard load through a small road artificial structure using the trailer truck t-truck.

Passing overload through a small road artificial structure 1 using as an unloading platform a trailer truck with a front truck 2 and a rear 3 chassis carriage and with a support platform 5 mounted on its frame 4 for cargo 6 in the following sequence.

217975

Before installing the autotrailer t of the timber truck as a unloading platform over the artificial structure 1, the support platform 5 with a load of 6 is displaced along the frame 4 to the rear undercarriage 3 (Fig. 1).

Next, the auto trailer is moved through the artificial structure 1 with the location of the front 2 and rear 3

10 carts on the opposite

the sides of the obstacle (Fig. 2). After that, the excess load is passed through the artificial structure by moving

15 of the supporting platform 5 with a load of 6 on the frame 4 of the autotrailer in the direction of its front chassis car 2 (Fig. 3) with the subsequent movement of the autotrailer in the direction of movement

20 and a passage through the artificial structure of the rear trailer trolley 3 of the autotrailer 3, freed from cargo 6 (FIG. 4).

 The application of the proposed method

25 greatly simplifies the operations of passing over-standard loads through small road artificial structures while at the same time eliminating the need to use

30 special designs of unloading platforms and ramp entries.

METHOD OF PASSING SUPERNORMAL LOAD THROUGH SMALL ROAD ARTIFICIAL STRUCTURES, including installation of unloading plate -. forms above the artificial structure and the excess load passing through it, characterized in that, in order to simplify operations. To pass the excess load through the small artificial structure while eliminating the need to use special structures of the unloading platform, an av, heavy trailer is used as the unloading platform '' with front and rear undercarriages and with a longitudinally-movable support platform mounted on its frame under the load, and before installing the autotrailer of the iron truck as an unloading platform above the artificial structure, the supporting platform with the load is displaced along the frame to the rear undercarriage of the heavy truck, the latter is installed over the artificial structure by moving the heavy truck through the artificial structure with the front and rear undercarriage located on opposite sides of the obstacle, and the excess passage the load is carried out by moving the support platform with the load along the frame of the heavy truck autotrailer in the direction of its front undercarriage with the subsequent movement of the heavy truck autotrailer in the direction of movement and passing through the artificial structure of its rear undercarriage.
