PROBLEM TO BE SOLVED: To provide a boom foot pin inserting/removing device capable of effectively reducing time for installation work and cost.SOLUTION: An inserting/removing device 30 comprises a pair of left and right hydraulic cylinders 31 for inserting boom foot pins 24 into pin holes 23 and lifting them from the pin holes, a cylinder holding body 32 for integrally holding the pair of hydraulic cylinders, and pin receivers 33 attached to the inner pieces of forked joint parts along the lower edges of the pin holes. The cylinder holding body has left and right side plates 32e, each of which is provided with a through-hole 35 through which each of the boom foot pins runs through, is configured so that the state where the ends of the boom foot pins project outward for a predetermined dimension from the through-holes in the side plates is the removal positions of the boom foot pins, and is provided so that the boom foot pins in the removal positions are placed on the pin receivers in two places on the left and right to perform alignment. |
