The first shock absorber 310 is disposed on the bottom of the loading space 101 . A fluid may be accommodated in the first shock absorbing part 310 . The first buffering unit 310 may be inflated or collapsed according to the amount of fluid accommodated therein.

The first buffering part 310 is preferably formed of a material having a certain elasticity and heat resistance.

Here, it is preferable to form a flat surface on the upper surface of the first shock absorbing part 310 so that the above-described load 1 can be seated.

Also, the second shock absorber 320 may be installed on a sidewall of the loading space 101 .

Preferably, the second buffer unit 320 may be arranged in plurality to surround an outer circumferential area of the first buffer unit.

Here, the fluid supplier 330 may be configured to independently supply fluid to each of the first buffering unit 310 and the plurality of second buffering units 320 .

In the present invention, the fluid supplier 330 may supply liquid or gas. That is, in the present invention, the first and second shock absorbers 310 and 320 may be inflated using a hydraulic or pneumatic method.

The controller 340 according to the present invention may control the driving of the fluid supplier 330 according to whether or not the load 1 is loaded.

The controller 340 is electrically connected to the fluid supplier 330 through wires.

And the fluid supplier 330 has pipes 331 for supplying or recovering fluid, and electromagnetic valves V installed in the pipes 331. The solenoid valves V are opened and closed under the control of the controller 340 .

Referring to its configuration, in the loading space, the first cushioning unit 310 and the second buffering units 320 form an inflated state (hereinafter referred to as a standby state).

When the load 1 is seated on the upper surface of the first buffer 310, the sensor unit 200 detects that the load 1 is seated and transmits a detection signal to the controller 340.

The controller 340 supplies fluid to the first buffer 310 using the fluid supply 330 to achieve an inflated state (hereinafter referred to as a buffer state). Accordingly, the loaded object 1 is lifted upward from the upper surface of the first shock absorbing unit 310 forming a buffered state.
