Title:
PANTOGRAPH ARM STRUCTURE SCAFFOLD BASE
Document Type and Number:
Japanese Patent JP2022052889
Kind Code:
A
Abstract:
To provide a pantograph arm structure scaffold base allowing cost reduction and improvement of safety measurements through shortening of steps associated with assembly and decomposition.SOLUTION: A pantograph arm structure scaffold base is pre-provided with a pantograph arm for every scaffold base 1, for which the scaffold base 1 move up and down through storing and telescopic motion of the pantograph arm with a detachable hydraulic cylinder. It allows assembly construction and decomposition operation to be carried out in short time as the operation itself is simple, and the number of workers as well as physical load, operation time, the number of steps and like in association with transportation work are reduced because most of scaffold members are in a storage state.SELECTED DRAWING: Figure 1-A
