FIELD: mechanical engineering; materials handling facilities. SUBSTANCE: invention can be used in load-lifting and transportation equipment, mainly, tower cranes in which observation requirements are to meet high standards. Proposed cabin has two semispheres, one of which is rigidly secured on base, and the other, made transparent, being hinge-coupled with first semisphere, is made for turning relative to vertical axis of cabin. Fixed semisphere is made three-layer, consisting of outer and inner layers separated by air gap in which two adjustable spherical surfaces are hinge-coupled with semisphere. EFFECT: improved heat and noise isolating properties of cabin, observation properties and performance. 2 cl, 3 dwg
