摘要
To provide a work machine connection device, a connection pin, a connection pin coupling device, a work machine connection method, and a connection pin removal method, in which the connection pin, which connects a plurality of structural members of a work machine and is disposed inside the structural members, can be easily inserted into a hole from the outside of the structural members.SOLUTION: A crane 10 includes a boom 16, a jib 18, a connection pin 70, and a pin removal tool 80. The boom 16 and the jib 18 are connected by inserting the connection pin 70 into a boom side hole 16Q of the boom 16, a jib side first hole 18Q and a jib side second hole 18S of the jib 18. An operator inserts a pin attaching/detaching tool 80 from the jib side first hole 18Q and engages with the connection pin 70. Thereafter, when the operator pulls the pin attaching/detaching tool 80, the connection pins 70 are sequentially inserted into the holes while being pulled.SELECTED DRAWING: Figure 3
