The invention is shown in the drawings, where:

- in Fig. 1 - cargo platform with a removable protective cover, main view;

- in Fig. 2 - the same, isometric projection;

- in Fig. 3, 4 - remote element "A" from Fig. 2 at different positions of the drive sleeve handle, isometric view;

- in Fig. 5 - an example of the relative position of the elements of the fixing device when orienting the removable casing over the cargo frame 1, local view;

- in Fig. 6, 7 - top view of the locking device at various positions of the drive sleeve handle, local view;

- in Fig. 8 is a diagram of the interaction of the conical head with the mounting groove in the support area of the cargo frame.

The cargo platform contains a cargo frame 1 (Fig. 1, 2) for placing cargo, a removable casing 2 with a roof 2.1 and walls 2.2 to protect the cargo. The removable casing 2 is fixed on the cargo frame 1 with the help of fixing devices 3. On the removable casing 2 there are support shelves 2.3 (Fig. 3, 4, 5), on which fixing devices 3 are installed. Each fixing device 3 is made in the form of a base 3.1 with a hole 3.2. In hole 3.2, a vertical rotary pin 4 with a guide conical head 4.1 with a diameter D _goal is installed with the possibility of rotation. On the guide conical head 4.1 at a mutual distance "H" there are two parallel side flats 4.2 and thrust ends 4.3, perpendicular to the longitudinal axis of the vertical rotary pin 4. The vertical rotary pin 4 contains a drive shank 4.4, on which longitudinal flats 4.5 are made. A drive sleeve 5 is installed on the shank 4.4, designed to transmit torque from the drive sleeve 5 to the vertical pivot pin 4 using internal protrusions 5.1 (Fig. 6, 7). The drive sleeve 5 is equipped with a handle 5.3.

These internal protrusions 5.1 are made at a mutual distance, allowing free longitudinal movement up and down of the drive sleeve 5 along the parallel side flats 4.5 of the vertical pivot pin 4, while maintaining engagement between the internal protrusions 5.1 and the side flats 4.5 of the drive shank 4.4 of the vertical pivot pin 4.

To fix the vertical rotary pin 4 when fixing the removable casing 2 on the cargo frame 1, the drive sleeve 5 is provided with thrust radial projections 5.2, which interact with the stop made in the form of a pin 6 fixed on the base 3.1 of the fixing device 3.

The stop interacting with the handle 5.3 can be made in the form of a thrust guide plate 7 fixed on the base 3.1 of the fixing device 3.

For support on the cargo frame 1 of the support shelves 2.3 of the removable casing 2, reciprocal support platforms 1.1 are made on the cargo frame 1. In each of the support platforms 1.1, a mounting groove 1.2 is made coaxially with the corresponding vertical pivot pin 4, designed to pass the guide conical heads 4.1 of the corresponding vertical pivot pins 4 and fix them together with the guide conical heads 4.1 by introducing flat thrust ends 4.3 of the guide conical heads 4.1 behind the lower surface 1.3 of the support platforms 1.1 of the cargo frame 1. The mounting groove 1.2 (Fig. 8) is made with a length L _hole greater than the diameter D of the _head of the guide conical head 4.1, and a width S _hole greater than the distance "H" between the parallel side flats of the conical head 4.1, but smaller than the diameter D of the head of the _conical head 4.1.

Support shelves 2.3 for placing fixing devices 3 on them can be placed in niches-pockets 2.4, made in the walls 2.2 of the removable casing 2.

At the upper end of the movable pin 4, a stop 4.6 can be made to fix the movable pin 4 in the drive sleeve 5.

The invention is used in the following way.

After placing the cargo on the cargo frame 1, for example, rolls of steel, paper, a removable casing 2 is used to protect the cargo from external adverse influences.

Removable casing 2 with the help of a lifting device (not shown) is installed on the cargo frame 1, supporting the support shelves 2.3 on the support platforms 1.1 of the cargo frame 1. Before that, the guide conical heads 4.1 of all fixing devices 3 with the help of the handles 5.3 are set to the position when the guide heads 4.1 can freely pass through the corresponding mounting grooves 1.2 of the support platforms 1.1. After placing the removable casing 2 on the frame 1 and the passage of the guide conical heads 4.1 through the mounting grooves 1.2, the removable casing 2 is fixed on the cargo frame 1. To do this, the drive sleeve 5 is lifted up, moving it along the parallel side flats 4.2 and disengaging the thrust radial protrusion 5.2 with the first finger 6, the handle 5.3 - with a thrust guide 7. For the handle 5.3, turn the drive sleeve 5 together with the movable pin 4 and its guide conical head 4.1, while its thrust ends 4.3 go under the bottom surface 1.3 of the supporting platforms 1.1 of the cargo frame 1 , rigidly connecting the removable cover 2 with the load frame 1. The drive sleeve 5 is lowered down, moving it along the parallel side flats 4.2, engaging the thrust radial protrusion 5.2 with the second pin 6, and the handles 5.3 with the thrust guide 7, thereby excluding the rotation of the drive bushing 5 and a movable pin 4 connected to it with a guide head 4.1. Similarly, all locking devices 3 are transferred to the working position.

To remove the removable casing 2 from the cargo frame 1, the clamps 3 are released in the reverse order.

For reliable fastening of the removable casing 2 on the cargo frame 1, an additional fixation of the handle 5.3 can be provided. To do this, a through hole 5.3.1 is made in the handle 5.3, and a through hole 7.1 is made in the stop guide plate 7, which are aligned coaxially when the handle 5.3 is turned while the removable casing 2 is fixed on the cargo frame 1. A lock is passed through these aligned holes, made, for example, , in the form of a piece of cable with connected ends, a lock shackle, cotter pin, wire, excluding the rotation of the handle 5.3 and the drive sleeve 5 together with the movable pin 4 and its guide conical head 4.1.

Thus, the presence in the design of the latch 3, the drive sleeve 5, fixed from rotation by the radial protrusion 5.2, interacting with the pin 6, the handle 5.3, interacting with the thrust guide 7, the possibility of installing additional latches in the holes 5.3.1, 7.1, as well as the need for additional forced movement of the drive sleeve 5 along the longitudinal flats 4.5 of the drive shank 4.4 when using the latch 3, is aimed at increasing the reliability of fixing the protective cover 2 on the cargo frame 1.
