PROBLEM TO BE SOLVED: To provide a rubbing block permitting easy and simple attachment and the removal of a marking and a suspension member, thereby assuring definite, safe lifting. SOLUTION: Attachment and removal of a marking 21 can be performed by inserting to or pulling out from a leg piece 22 of a marking 21 to an insert hole 2 of an attaching means 1 embedded in the rubbing block B. Also, a shaft body 12 and a linking projection 13 of a suspension member 11 are inserted to an insert hole 3 of the attaching means 1 and a guide groove 4, then, the suspension member 11 is coupled to an attaching means by turning and fitting the linking projection 13 to a linking groove 6 of the attaching means 1, thereby permitting the lifting, carrying and suspended descent by heavy machinery. |
