Construction machine equipped with boom
Provided is a construction machine capable of suppressing deformation of a boom in a simple configuration and at low costs. The construction machine includes a pair of backstops having respective hydraulic cylinders; a supply device which supplies the hydraulic cylinders with hydraulic fluid; a deformation sensing device which senses deformation of the boom; and a control device which controls the supply device so as to make a thrust of the hydraulic cylinder of one backstop having a larger pressing force, out of the pair of backstops, be larger than a thrust of the hydraulic cylinder of the other backstop, the pressing force being applied due to the deformation of the boom.
