When using this method, remove the pan bolts to the frame of the machine, it is necessary manually to keep it from falling, then manually lowered its edge on the ground. Given that the weight of the pallets tractors T-130 50 and 60 pounds, the use of the known method is difficult and unsafe. For heavier pallets this technique is generally unacceptable.

The known method of removal and installation of protective pallet, including delivery to the machine is a special device, installing it under the pallet, the twisting of the pan bolts to the frame of the machine,

A device for carrying out the method of removal and installation of protective tray, made in the form of a trolley-hoist that includes a base with wheels, bearing and hydraulic lifting device (the"maintenance manual for tractor D-7G "CATERPILLAR,"", FORM NO. SENR 7112, USA, 1977, S. 34-35. A copy is attached.)

The closest major signs and the achieved result is the method of removal and installation of protective pallet, including delivery to the machine is a special device, installing it under the pallet, the twisting of the pan bolts to the frame of the machine, lowering the pallet by means of a special device, reverse the order of operations for installing a sump.

The device for implementing the method of removal and installation of the tray selected for the prototype, contains made in the form of a frame on wheels frame associated with support, established, with the ability to move and tucked up her protective pallet lifting mechanism support. (The mechanism for lifting and lowering the protective pallets IGOS-150", Passport, 720-16-PS, JSC "Chelyabinsk tractor plant", 1995. Copy attached).

The main disadvantage of the known methods and devices for their implementation is that they can about the social device, having a fairly complex design and are due to the significant size and weight are stored at the maintenance station. Therefore, it takes a long time for delivery of the device for removal and installation of protective pallet to the machine or the machine at the service station.

The aim of the invention is the reduction of time for maintenance of wheeled and tracked vehicles in the field, associated with the removal of the protective pallets, due to the exclusion of the operation of delivery of the device to the machine and using a small device, stored on the machine.

This objective is achieved in that in the method of removal and installation of protective tray, which is placed under the pallet device for removal, twisting the pan bolts to the frame of the machine, remove the axes of the hinges of the pallet, the authors suggest to first Unscrew one bolt on the side of the pallet, made without loops, and in its place install the device for removal and installation of the pallet, then Unscrew the remaining pan bolts, then lower the pallet to the ground, to move the device for removal and installation of the pallet in the hole for the bolt on the opposite >/P>This goal is achieved by the fact that the device for removal and installation of protective pallet comprising a frame, a support mounted for movement and preload it protective tray to the frame, mechanism for moving the support, the authors suggest the skeleton to perform in the form of a rod, which consists of two parts connected by a hinge, the upper part of which is threaded, and the lower part of the installed bearing.

When running supports in the form of nuts lower part of the rod is threaded.

The upper and lower part of the rod is made with a thread having a different direction.

The proposed method for removal and installation of protective tray allows for quick and timely maintenance of the machine in the field, since the proposed device for carrying out the method has a small weight and dimensions, which allow you to include it in the composition of the spare parts of the machine.

In addition, the use of the machine frame as a support for fastening the proposed device can be used to repair a car on relatively soft ground, which is quite difficult when using truck-lift (wheel pressed into the soil, the necessary specie technical solutions linked to form a single inventive concept.
