Abstract

Provided are a sliding support member for booms easily mountable on an outer boom member and allowing position adjustment of an inner boom member relative to the outer boom member; a boom for construction machine having the sliding support member for booms; and a method for assembling a boom for construction machine. The sliding support member slidably supports an inner boom member 12 while fixed to an outer boom member 11, having a plurality of sliding pads 20 and a holder 30 holding them. Each of the sliding pads 20 has a surface 20a for contacting the inner boom member 12. The holder 30 is fixed to the inner peripheral face of the outer boom member 11 to hold the sliding pads 20 allowing them to be inserted and removed through the front end of the outer boom member 11.
