STUDY ON DRAGGING VERTICAL EVACUATION IN FACILITIES FOR THE ELDERLY RELATIONSHIP BETWEEN PULLING

－Force and time in stair-ascent-evacuation on a u-shaped staircase－

Abstract

Two subjects lifted 45.0 kg (measuring equipment and humanoid dummy) upstairs on the slope installed on the U-Shaped staircase which includes a landing at the switchback. The pulling force and the required time were measured. The experiment was repeated 3 times on each pair. A large amount of pulling force is continuously required on the slope. A large momentary pulling force is required at the landing. Female-female pairs with a small sum of back muscle strength takes a long time. It became clear that the evacuation time can be greatly shortened if there is at least one male caregiver.
