“…Wind study on the abrasion of mild steel in pure water by Doi et al (1975), the friction coefficient between stainless steel and chromed mild steel in pure water was approximately half that under the dry condition. Therefore, the static friction coefficients between the clamp pads and the rails and between the driving wheels and the rails were set to be approximately half the static friction coefficients under the dry condition of JCAS, as defined in the guidelines for the device for preventing crane runaway (JCAS 1201(JCAS , 2009b.…”
