about

The invention relates to a lifting equipment, namely to cargo carts intended for lifting and transporting long items in the case when their center of gravity is above the point of suspension.

The purpose of the invention is to improve performance.

FIG. 1 shows the special device and the hoisting ropes of the chain hoist, general view; in fig. 2 - longitudinal inserted in a vertical position: in FIG. 3 - fastening the support unit to the trolley; in fig. 4 — relocation of the traverse for further lifting of the length gauge; in fig. 5 - raising the length gauge to the extreme upper position: in FIG. 6 shows section A-A in FIG. 3; in fig. 7 - drag clamp design; in fig. 8 - design of the collar-brace.

The device comprises a cargo cart 1 with lifting and moving mechanisms, traverse 2, the gripping organ of which is a split bolt and drag hooks 3 and 4, consisting of two half-housings bolted. The assembly of the device includes a support unit 5 with guide rollers 6, studs 7 for fastening it to the frame of the trolley 1 with nuts 8 and clamp-rascal-. 9, which is fixed on the frame of the trolley with the help of lanyards 10. The frame of the trolley has an opening 11 for the passage of the length gauge 12 and the apertures 13 for fastening the yoke brace 9 with the lanyards 10.

The clamp-brace 9 consists of two half-winches 15, covering the body of the length gauge 12 and set springs 16 with a force preventing slipping of the clamp-brace 9 along the gauge 12 under their own weight. On the outer side of the yoke bar 9, four straps 17 are fastened, fitted with lanyards 10. The lug gripper 3 or 4 consists of two half clamps 18, spanning the body of the length gauge 12 and bolted 19 with a force preventing slipping of the gauge length 12 in the gripper 3 or four.

Splaying of the length gauge 12 is carried out in a horizontal position. The pickup organ of the crosshead 2 is a deadbolt with a hole that is slightly larger than the length of the covered length 12. The crossbar is made detachable and has the possibility of axial rotation.

The axial movement of the linnomer 12 in the bolt is limited to one side by means of the drag grip 3. Between the crossbar, the crosshead 2 and the drag hook 3 on the length 12, during slinging, the support unit 5 and the brace strap 9 are installed.

The length gauge 12 is brought into a vertical position by means of a standard crane truck: length 12 is raised in a horizontal position at the same time by a hook of a standard crane truck and crosshead 2 of a special device, then transferred to a vertical position by lowering the hook of a standard trolley. After the length gauge 12 is in the vertical position, the hook of the standard car is removed and further work is carried out only by a special device.

The length gauge is lifted up to the entry of the studs 7 of the assembly 5 into the holes 13 of the frame of the trolley 1, after which the support assembly 5 is attached to the frame of the trolley 1 by nuts 8, the yoke 2 is lowered to the desired position and length 12 is intercepted by another hook grab 4. During the lowering the traverse 2, the length dimension 12 is prevented from falling by the drag grip 3 through the studs 7 of the support assembly 5.

When the yoke brace 9 comes up to the height of the brackets 14 of the trolley 1 when the dlinier 12 is further lifted vertically, the braces are fixed to the brackets 14 and stretched with lanyards 10. When the yoke bracing 9 is creased, the half clamps 15 consumed a gap that allows free axial movement of the length gauge 12 in the brace brace 9. With the turnbuckles 10, the axis of the length gauge 12 is also adjusted vertically to reduce the tilting moment.

After this, the length meter 12 is raised to the required height. The lowering of the length meter 12 is performed in the reverse order.
