Description

Electric crane for demolition of high-rise buildings {omitted}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric forklane equipped with a cutting machine for demolishing a high-rise building, wherein a conventional forklrawn having a fork-crane or a scissors hand is limited in height when demolishing a high-rise building, It is difficult to keep the balance of its own weight and it may lead to human accidents. The present invention proposes an electric forklift for high-rise building demolition with a high-rise building demolition cutter that can be used in a high-rise building of two to three times the conventional forklings, And more particularly to an electric forklift for demolition of a high-rise building capable of performing demolition.

Conventionally, forklifts have been mainly used to transport scrap iron to cutters or compressors within excavation, trench construction, foundry, and waste treatment facilities. In addition, the conventional demolition of the building uses a fork-crane car, and it is composed of two stages between the support stand and the support, so it is possible to demolish only within 10m of the height of the building, and it is necessary to mobilize various high- It has been difficult to demolish high-rise buildings.

However, in the conventional forklans, when the work is performed over a certain height of the object to be worked, the center of gravity does not fit, resulting in overturning and human accidents. Particularly, in order to remove a demolition object more than two times to three times the conventional work height of the crane, demolition by explosive explosion usually used for demolishing high-rise buildings is carried out. However, it is difficult to dismantle adjacent and neighboring demolished buildings due to explosive demolition, and in fact, cost and safety problems due to explosive demolition can also occur.

Until recently, there have been some embodiments of the electric forklift for demolition of a high-rise building and the equipments of the excavator for the excavator in the same manner as the conventional crane structure, but there is a structure different from that of the present invention, I have problems that exist. (20-0193180, 20140137806)

Therefore, in general, the present invention proposes an electric flare for high-rise building demolition having a high-rise building demolition cutting machine which can be used for a high-rise building of 2 to 3 times higher than that of a conventional fork- We propose an electric forklift for the demolition of high-rise buildings that can be efficiently cut and demolished.
