PURPOSE: To facilitate vertical division and to improve workability by a method wherein a rotary coupling usually attached to a lower running body side is attached to the upper part side and upper and lower piping connection part are arranged in a good order state and work is practicable from the lower running body side, in a vertical division system of a crane. ;CONSTITUTION: In a crane being of a type where upper and lower slewing bodies A and B are divided from each other, division to the upper slewing body A side is effected in a state that a bracket 5 being a part of the fixed part of the lower running body B and a piping support 6 are annexed to a vertical mounting demounting part C. By utilizing the vertical mounting and demounting part C, a piping on the lower running body B side is orderly arranged and a work to separate a piping support 6 away from a piping is practicable.;COPYRIGHT: (C)1994,JPO
