摘要
The invention relates to an assembly (10) having a boom (4) that can be luffed between a storage position (P1) and a working position (P2) within a vertical luffing plane (WE) by at least two luffing cylinders (5a, 5b), the luffing cylinders (5a, 5b), which lie opposite one another on the luffing plane (WE), enclosing a spread angle (a) between their longitudinal axes (x1, x2) in the working position (P2), and the luffing cylinders (5a, 5b) acting on the boom (4) outside its ends. In order to achieve a design that is as compact as possible, particularly when the boom is in the storage position, according to the invention the longitudinal axis (x1, x2), projected onto the luffing plane (WE), of one luffing cylinder (5a, 5b) and a vertical direction (Z) extending within the luffing plane (WE) enclose an angle of inclination (b) therebetween when the boom (4) is in the storage position (P1).
