In a gantry crane having a vertically movable, horizontal stabilizer beam spaced between upright columns, a shock absorbent bumper assembly is mounted to ends of the stabilizer beam to prevent direct contact against the columns. The bumper assembly includes an elastically deformable bumper body made of resilient material and a wear pad made of wear resistant material, the wear pad being secured to the bumper body so that the wear pad faces the column. The wear pad resists wear due to sliding contact against the column and the resilient bumper body absorbs energy from impacts as the stabilizer beam shifts in a transverse direction.
