ン。 。[Scope of claim for utility model registration] 1. The crane boom provided on the crane body is
It consists of a split crane boom consisting of a boom i, an upper boom, a plurality of joint booms inserted between both booms, and a joint that connects each boom.The joints connect the eye end and the eye end. It consists of a hawk end that fits together, and a connecting pin that is inserted into a pin hole drilled in both. When disassembling and assembling the split crane boom,
The boom hoisting device pendant rope connector is connected to the lower boom or the joint boom to hold the lower boom or the lower boom and the joint boom horizontally, and the intermediate support rope connector is connected to the boom hoisting device during hoisting work of the split crane boom. In a mobile crane that is connected to the middle of a split crane boom to support the split crane boom, a pin hole into which the connecting pin can be inserted is provided in the connector of the pendant rope or the connector of the intermediate support rope; The pin has a length that can be inserted into the pin holes of the eye end, the hawk end, and the connector, and the connecting pin has a first retaining pin hole and a second retaining pin hole, and the first retaining pin hole By inserting a retaining pin into the second retaining pin hole, the eye end and fork end are prevented from coming off from the connecting pin, and by inserting the retaining pin into the second retaining pin hole, the eye end, fork end, and d connector are connected. A mobile crane equipped with a split crane boom, characterized in that the crane boom is configured to prevent the boom from coming off the pin. 2. The length of the connecting pin is such that when the connecting pin is inserted into the eye end, the hawk end, and the pin hole of the connecting tool, it can protrude from both sides of the connecting tool, and the first retaining pin hole is:
Two holes are provided at a distance slightly larger than the width of the eye end and hawk end, and the second retaining pin hole is
The width of the eye end, the hawk end, and the connector are two at a distance from each other, and the connector is the second one.
The split type according to claim 1 of the utility model registration claim, characterized in that a hole for a locking pin and a hole for a locking pin corresponding to the locking pin hole are provided, and the connecting pin and the connecting tool □ are aligned with each other by the locking pin.
