Abstract

The purpose of the invention is to mechanize the handling washing machine for loading and unloading vehicles. This purpose is achieved by forklift straddle carriage consisting of from a wide-track bogie (2j and a chassis) (lj on which is fixed) frame (3) with guide (5) for fork (4) as a guideway (6j for a wide-track bogie) (2). A load truck is also loaded from the vehicle (10) using a wide-gauge the chassis (2) moving on the ramps folding bridges (8) on the vehicle (10) and supported by supports (9). Known lifting jacks are used for lifting devices.

Description

The purpose of the invention is to mechanize the handling operations for loading and unloading vehicles.

This is achieved by a straddle truck consisting of a wide track chassis (2) and a chassis (1) on which a fixed frame (3) with a guide (5) for the forks (4) and a guide (6) for the wide track (2) is attached. . The load truck shall be loaded: (a) consisting of a vehicle (10) by means of a wide-gauge bogie (2) traveling on ramps (8) hinged on the vehicle (10) and supported by supports (9). Known lifting devices are used for lifting.

The invention relates to a device for loading and unloading, in particular for loading vehicles. The device is suitable for loading and unloading of various materials, both in lump and in boxes, containers, on pallets, etc.

Various versions of vehicle loading and unloading devices such as e.g. truck mounted aerial platform, truck mounted crane, forklift. The mast is automatically tilted using the parallelogram when lowered to the ground and raised to the vehicle body. The crane arm is mounted on the vehicle between the cab and the cord. The forklift is transported behind any part of the vehicle, supported by forks and lifted. The main disadvantage of these devices is the manual handling when the material is fed to the vehicle or after it has been loaded onto the vehicle.

The above-mentioned disadvantages are overcome by the loading and unloading device according to the invention, characterized in that the straddle straddle consists of a chassis on which a frame with a fork guide and a wide-track chassis are mounted, which can be folded onto the vehicle by means of ramps. , load and unload from the vehicle.

This design creates the conditions for mechanized material handling when moving to the vehicle, on a narrow-track chassis, self-loading on the vehicle using ramps that may be part of the vehicle and mechanized handling on the vehicle, and too on a wider-track chassis .

An exemplary embodiment of a loading and unloading device according to the invention is shown schematically in the accompanying drawings, in which: FIG. 1 is a side view, FIG. 2 is a rear view showing the trolleys with thin lines and the loads indicated by lines; and FIG. 3 is a device on the ramps of a vehicle in a partially laden position and in thin line in a transport position with a dotted load.

The loading and unloading device consists of a bogie 1 on which a frame 3 with a guide 5 for the forks 4 and a guide 6 for the wide gauge 2 is fixed. The long hydraulic cylinder 11 is mounted on the bogie 1 and its piston rod on the broad gauge 2. 12 is mounted on the chassis 1 and its piston on the fork 4. The ramps 8 with supports 9 are hinged on the vehicle 10.

For the operation of the loading and unloading equipment it is necessary to lower the ramps 8 from the transport position and support them with the supports 9. The straddle truck moves on the wide gauge 2 from the hull 7 of the vehicle 10 to the ramps 8. of the cylinder 11, the chassis 1 with the fork 4 drops to the ground. By further supplying the pressurized fluid to the bottom of the long hydraulic cylinder 11, the wide track chassis 2 is lifted off the ramps 8. The fork lift truck can leave on the load chassis 1. By feeding the pressurized fluid to the top of the hydraulic cylinder 12, the fork 4 is lowered so that it can be pushed under the load. By supplying the pressurized fluid to the bottom of the hydraulic cylinder 12, the fork 4 is lifted with the load. The forklift on the chassis 1 moves the load to the vehicle 10 so that the wide track chassis 2 is above the ramps 8. The pressure fluid supplied to the upper part of the long hydraulic cylinder 11 ensures that the wide track chassis 2 is mounted on the ramps 8 and lifted the chassis 1. and the fork 4 with the load to the plane of the hull 7 of the vehicle 10. The straddle truck including the load is transported on the wide gauge chassis 2 from the ramps 8 to the hull 7 of the vehicle 10, where it loads the load.
