Abstract There is provided an outrigger connection locking device used in a crane apparatus including a boom, a swivel base that 5 supports the boom so as to be raised and lowered, a carrier frame on which the swivel base is mounted, and an outrigger removably mounted to the carrier frame. The outrigger locking device includes: a connection pin that can be inserted into a carrier frame hole formed in the carrier frame and into an outrigger 10 hole formed in the outrigger; a telescopic cylinder that performs a telescopic motion that allows the connection pin to move to a location in which the connection pin is inserted into the carrier frame hole and the outrigger hole; a connection locking unit that restricts the connection pin inserted into 15 the carrier frame hole and the outrigger hole from moving; and a remote operation mechanism for connection locking that can operate the connection locking unit. 43 43 101 43 43 41-- 4 41 91 -- 102a 44 92 94 44 82 81 e4 85 81 a 93a 938 81 b |
