In such a side excavation device, the boom of the work attachment is divided into a rear boom and a front boom, a slide beam is provided between the front end of the rear boom and the rear end of the front boom, and the front end of the slide beam is The rear end of the front boom can be slid in the left and right directions perpendicular to the front-rear center line of the rear boom, and the relative positions of the two can be locked at a desired position. The rear end of the slide beam is configured to be able to slide in the left-right direction perpendicular to the front-rear center line of the rear boom, and to lock the relative positions of the two at a desired position. Characteristic side drilling equipment. (2) Utility Model Registration Claims In the side drilling equipment described in claim 1, the slide beam is provided with a rack or screw rod, and the pinion or female thread corresponding to the rack or screw rod is connected to the rear boom, Installed on the front boom,
By rotating the pinion or the screw rod, the sliding parts of the front end of the rear boom and the rear end of the slide beam, and the front end of the slide beam and the rear end of the front boom are slidably moved. side drilling equipment.
