Basic Experiment for a Fastening Device for the Vertical Outer Walls of High-Rise Buildings

In order to perform maintenance on the outer walls of a high-rise building, including sweeping, painting and repairs, a device that enables the easy attachment/detachment of working equipment such as a gondola to the outer wall of a building is necessary. Though vacuum suction pads can be used to fasten equipment to a vertical wall easily and without causing damage to the contact surface, their suction force should be designed by considering both external conditions and the loads of working equipment.

In this study, we performed a basic experiment on the vacuum suction force of suction pads attached to a vertical wall under various load conditions.
