FIELD: transport.

SUBSTANCE: extendable sidewall of dump box consists of wall panel (1) which has parallel telescopic struts (2) actuated by double-acting pneumatic or hydraulic cylinders (3) fitted inside them. Upper parts of innermost sections of telescopic struts are pivotally connected with load-bearing member of body. Axes of strut rotation coincide with each other, are parallel to body bottom and virtually intersect with longitudinal axis of telescopic struts. Overall length of wall panel with telescopic struts structure does not prevent its extension into body interior space.

EFFECT: higher unloading efficiency including the case when body is partially tilted, design compactness.
