So that it relates to one piano carriage.

In general, a piano is one of heavy load instruments, and when two or more workers are required to move such a piano for moving or displaying or storing.

Of course, although the wheels are provided at the bottom of the piano's legs, as the wheels are pressed by heavy piano loads, the tracks of the wheels appear on the floor of the room as they are pushed and carried by the wheels. If severe, there is a problem that the scratch occurs.

Moreover, when carrying a piano for moving, a problem arises that the floor of the newly occupied house is offended by scratches generated when the piano is carried.

In addition, because of the difficulty of transporting the piano, if there is a piano, the transport cost of the piano must be additionally paid separately from the moving expenses, and it is difficult for a single worker to carry a heavy piano. It is often carried by lifting or lifting.

On the other hand, while the piano is temporarily heard, the piano is placed on a pallet with wheels at the bottom, and then the pallet is being transported using the pallet. The work that comes off of it is also a difficult problem.

In severe cases, lifting or lowering a heavy piano may cause other problems such as an injury to an operator's back as well as an expensive piano being damaged from the pallet if the center of the piano is not properly aligned.

Looking at the prior art to carry heavy cargo, things, furniture, goods, such as a piano, for example, a carrier for cargo transportation, registration room 20-0336299 has been laid out, which is the vertical body of the vertical body is installed on the lower wheels on both sides The fixed body is fixed to the upper center of the rear, and the rotating handle and the first chain wheel interlocking with each other at the distal end of the fixed body, the fixed plate is fixed to the lower front of the vertical body, and interlocking with the rear and one side The gearbox on which the two chain wheels and the third chain wheels are installed is installed in the upper rear center of the fixing plate, and the first rotating shaft having the fourth chain wheel at the center and the fifth chain wheel and the six chain wheel at both sides is provided. It is installed on the upper part of the front of the vertical body through a pair of support brackets, and the mounting plate provided with the vertical bending part at the rear is installed on the upper part of the fixing plate, and the seven chain wheels and the eight chain wheels on both sides The second rotating shaft is installed in the center of the vertical bent portion of the loading plate through the support bracket, and the elevating coupling pipe provided on both sides of the vertical bent portion of the loading plate is inserted into the elevating guide shaft fixedly installed on both sides of the front of the vertical body. A first chain is installed between the first chain wheel of the fixed tube and the second chain wheel of the gearbox, and a second chain is installed between the third chain wheel of the gearbox and the fourth chain wheel of the first rotational shaft. The other end of the third chain and the other end of the fourth chain, which are wound around the fifth chain wheel and the sixth chain wheel of the first rotation shaft, are wound around the upper part of the seventh chain wheel and the eighth chain wheel of the second rotation shaft, and then vertically It is configured to elastically support with a spring fixed to the lower part of the main body.

As another example, a freight transport cart having a lifting function of registration room 20-0411721 has been devised, which includes two vertical frames formed vertically long and a pair of wheels formed on an axle fixed to the lower part of the vertical frame. In the cargo transport cart consisting of a support frame formed on one side of the lower portion of the vertical frame, the handle on the other side of the vertical frame, integrally with the loading table loaded with the load along the guide groove formed on the inside of the vertical frame A moving frame configured to move up and down, a horizontal frame fixed horizontally on top of the two vertical frames, and an operating part formed at an approximately middle portion of the horizontal frame so that the moving frame moves up and down And, formed on one side of the axle is composed of a fixing device for fixing the moving frame is lowered The.

Such prior arts make it easier to carry heavy cargoes, but there is a problem that the transport of sophisticated instruments such as pianos is practically impossible.

In addition, the prior art has a problem that it is difficult to lift the heavy cargo as the lifting means for lifting the heavy cargo is to be turned directly to the operator's hand.

In addition, the prior art has a problem that it is difficult for the operator to drag and carry as the weight of the heavy cargo is transferred to the wheel as it is to move to transport in the lifted state.
