Abstract

There is provided an outrigger connection locking device used in a crane apparatus (3) including a boom (6), a swivel base (5) that supports the boom (6) so as to be raised and lowered, a carrier frame (4) on which the swivel base (5) is mounted, and an outrigger (7) removably mounted to the carrier frame (4). The outrigger locking device includes: a connection pin (84, 85) that can be inserted into a carrier frame hole (44) formed in the carrier frame (4) and into an outrigger hole (73) formed in the outrigger (7); a telescopic cylinder (81) that performs a telescopic motion that allows the connection pin (84, 85) to move to a location in which the connection pin (84, 85) is inserted into the carrier frame hole (44) and the outrigger hole (73); a connection locking unit (9) that restricts the connection pin (84, 85) inserted into the carrier frame hole (44) and the outrigger hole (73) from moving; and a remote operation mechanism (10) for connection locking that can operate the connection locking unit (9).

Description

Technical field [0001] The invention relates to a leg connection and locking device for a crane device. The crane device is provided with a leg that is detachably mounted on a carrier frame, and the boom is supported on the carrier frame, and the locking device is connected through the leg , Can lock the connection state between the carrier frame and the legs. Background technique [0002] In recent years, large crane devices that are prohibited by laws and regulations from passing on highways have been continuously developed. For this kind of large crane device that is forbidden to travel on the highway, it needs to be broken down into several parts and transported by a handling vehicle, and then the broken parts are assembled at the work site. [0003] Among the components of the crane device, for the leg with a certain weight, it is thought of separating it from the carrier frame (the crane device body) and separately loading it on the trailer for transportation, and then the c...
