Abstract
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.
Claims15
A load moving device including a base member provided to support at least part of a load to be moved;

- a skirt member surrounding said base member and having a seal operative between said skirt member and said surface and tending to prevent the passage of said lubricant beyond said skirt, and means for scavenging said lubricant in the region between said skirt member and said base member.
A scanning radio antenna supported for rotational movement, at least in part, by a device as claimed in any of the above claims.
