Load moving devices

摘要

A load moving device consists of a base member which supports the load to be moved and slides over a surface over which the load is to be moved. A lubricant such as grease is introduced between the base member and the surface and in order to prevent a trail of grease being left when the load is moved a skirt is arranged to surround the base member. A seal is operative between the skirt member and said surface to prevent the passage of grease beyond the skirt and the surplus grease within the skirt is scavenged for re-use.
