1. A hoisting implement used for hoisting a long object to be mounted on a construction machine using a hoist rope including a first end and a second end, the hoisting implement comprising:
at least one set of a first connection part and a second connection part disposed on the long object so that a center of gravity of the long object comes between the first connection part and the second connection part along a longitudinal direction of the long object, the first connection part and the second connection part each allowing the hoist rope to be connected to the long object,
wherein the first connection part is fixed to the long object so that the first end of the hoist rope is connected to the first connection part, and
the second connection part includes
a link having a distal portion to which the second end of the hoist rope is allowed to be connected, and a proximal portion opposite to the distal portion,
a swing supporting portion fixed to the long object to swingably support the proximal portion of the link, and
a holding portion capable of detachably holding the distal portion of the link laid against the long object along the longitudinal direction of the long object.
