Description

2. A loader according to Claim 1, characterized in that said mechanism consists of rotation cylinders of a multi-shaft grip and a lever, the corresponding cavities of which are connected in parallel and connected to the hydraulic distributor, while the hydraulic grips of the rotation of the grip are hinged on the carriage in niches and connected to the grip flexible elements, rounding rollers mounted on the carriage and the invention relate to loaders for working with packaged cargoes.

The purpose of the invention is to increase maneuverability when working in cramped conditions.

Fig, 1 shows a loader with a load; figure 2 - the same, with the folded work items; in FIG. 3, the same, with the pushing forward; Fig, 4 - view of Anafi.g.1; in FIG. 5, node 1 in FIG. 1; Fig. 6 is a hydraulic drive circuit.

The loader contains a forklift 1, on the movable carriage 2 of which the plate 3 is fixed with the lever pusher 4, the Plate 3 has brackets with axles for fastening the hydraulic cylinders 5, the lever 6, the cylinder 7, the deflecting rollers 8, and a multi-locking grip consisting of a beam 9 with pins 10 and cheeks 11 with openings under axis 12 for connection to the plate 3; The chains 13 are eccentrically connected to the cheeks 11 with axes 12 with fingers 13. Chains bend around the deflecting rollers 8 and connect other ends to cylinder rod 5, Lever 6 one shoulder is connected with the cylinder rod 7 to the other I am treating the runner 14 on the axles. There are stops 15 on the lever 6 that restrict the rotation of the runners, and on the plate 3 there are stops 16 to limit the horizontal position of the multi-locking grip.

united with one end with the cylinder rod, the other with the capture eccentrically to the axis of its rotation, and the clamping element is made in the form of several runners installed "on the indicated lever between the gripping pins with the possibility of their interaction with the folded collider, and the ends of the runners. Bent up and balanced , and the indicated lever is provided with stops to limit the rotation of the runners.

The hydraulic system of the loader includes a hydraulic distributor simultaneously controlling cylinders 5 and 7. A loader without a package moves with

folded grip. Driving up to the pallet with the package, the driver moves the valve 17 to the position. The grip is open. The rods, pulled out of cylinders 5 and 7, turn pins 10, lever 6 and pressure rails 14 into a horizontal position. Vz in the package on the pins, the driver transfers the valve 17 to the position of the Capture is complex, which corresponds

Fails on the package on pins position The package is clamped.

Cylinder 7 skid mi 14 presses the bag against the pin m. After reaching the place of installation, the driver moves the control valve 17 to the Locking position opened. After facing the packer by opening the packer 4 and returning the pushbacker to the initial position, the driver moves the control valve 17 to the Capture position. Cylinders 5 rotate by means of chains 13 pins 10 into a vertical position, and CI.TCHNDR 7 - lever 6 down. In this case, the stops 15,

by interacting with runners, they are prevented from turning into a horizontal position. When the skid, when turning the lever, interact with the frame of the collider 4,

the turn of the runners begins.

Turning the lever 6 and the runners 14 will end at the same time.

1. LOADER FOR WORKING IN CONFINED CONDITIONS, comprising a gripper mounted on a carriage with the possibility of vertical movement of multi-pin gripper, a pusher and an upper lever with a clamp pivotally mounted on it, characterized in that, in order to increase maneuverability, a multi-pin gripper and lever with a clamp of mounts with the possibility of folding in a vertical plane, it is equipped with a folding mechanism for multi-pin gripper and lever with clamp. Fig. / Yo f SL SL f 2. The loader according to π.1, characterized in that the mechanism consists of multi-pin gripper and lever hydraulic cylinders, the corresponding cavities of which are connected in parallel and connected to the control valve, while the hydraulic cylinders for the grip are pivotally mounted on the carriage in niches and are connected with the gripper flexible elements that envelope the rollers fixed to the carriage and with one end connected to the cylinder rod, the other with the eccentric capture of the axis of rotation, and the clamping element is made in the form of several runners, anovlennyh Ra said gripping arm between the pins to engage them with folded pusher, the ends polozev.zagnuty up and balanced, and said lever is provided with stops for limiting the rotation of the runners.
