Description

 The invention relates to ground handling of aircraft, in particular to devices for transporting, lifting and suspending cargo.

 A device for transporting and hinging goods [1] containing a trolley consisting of a frame with guide rails, and a cargo platform with supporting lodges.

 The disadvantage of this device is the inconvenience of its operation.

 A device is known for transporting, lifting and suspending cargo onto an aircraft [2] comprising a trolley with a frame, a loading platform and cable-block mechanisms.

 The disadvantages of the known device are the inconvenience of operation and limited capabilities, since due to the constant longitudinal base of the trolley it is designed to serve cargo only a certain length.

 The purpose of the invention is to reduce the time for preparing the cargo for suspension and to reduce the load on the cable mechanism, which ensures ease of use.

 The goal is achieved in that in a device for transporting, lifting and suspending cargo on an aircraft containing a trolley with a frame, a cargo platform detachably mounted on the frame and cable assemblies connected to the winches, the cargo platform and the frame are provided with mating connectors, and the winches are mounted on the cargo the platform.

 In addition, the connecting fastening nodes are made in the form of catcher pins mounted on the frame, interacting with mating sockets formed on the cargo platform.

 Another effect is improved performance by ensuring operability with long loads. This is achieved by the fact that the frame is equipped with a cantilever mounted towbar with a towing fork mounted at its end.

 In FIG. 1 given the device with the installed load, General view; in FIG. 2 the same, with a raised load; in FIG. 3, section AA in FIG. 1; in FIG. 4 a section BB in FIG. 2.

 The device comprises a transport trolley 1 with a frame 2, a removable cargo platform 3, consisting of longitudinal guides 4 and removable power transverse beams 5, cable-block mechanisms 6 for lifting cargo 7 and load bearing lodges 8.

 The cable-block mechanisms 6 consist of winches 9, blocks 10 installed on board the aircraft, and blocks 11 and 12 mounted on the axes of the ear brackets 13 and 14 at the ends of the removable transverse beams 5. Moreover, the winches 9 are mounted on the frame of the cargo platform 3.

 At one end of the transverse beam coaxial to one of the blocks, for example 11, a two-shoulder rocker 15 is installed, the locking arm 16 of which is made with a radius stop a and is installed with the possibility of interaction with the stop b on the beam 5, and a cable is stocked on the second rocking arm 17.

 The cargo platform 3 is mounted on the frame 2 of the carriage 1 by means of docking units 18, consisting of catcher pins 19 on the stationary frame 2 of the carriage 1 and mating sockets 20 on the cargo platform 3. At the rear of the frame 2 of the carriage 1, a telescopic towing bar 21 with a coupling bar is mounted fork 22.

 To carry out the operation of transporting, lifting and hinging cargo 7 onto an aircraft, the cargo is mounted on load bearing lodges 8 and secured with clamps then, simultaneously turning the handle of the winches 9, the cargo platform 3 with cargo 7, lift the cargo to the required height through cable blocks 6 and orient it the nodes of the load, respectively, the response nodes on board the aircraft, push the load 7 on these nodes and secure it.

 Then remove the clamps from the lodgements 8 and lower the cargo platform 3 with the help of winches 9 to the docking nodes 18 on the frame 2 of the truck 1.

 If there is a load 7 of greater length, while maintaining a support base on bearing lodges 8, the proposed trolley can be used for transportation and suspension of cargo, it is necessary to extend the telescopic rod 21, remove the coupling fork 22 from the tail of the cargo mounted on the rod, thereby protecting the tail of the cargo from damage by the carrier of the subsequent carriage during transportation of the carriage in the hitch "train" (one and the other) to the aircraft. Using the proposed device will reduce the time of preparation of the aircraft for use by 10 minutes; improving ease of use.
