The invention relates to a crane (1) comprising: a column (2); an elongated boom (3) connected to the column, the elongated boom having a front portion (6) extending on one side of the column and a rear portion (8) extending on an opposite side of the column, the boom (3) being linearly movable relative to the column, the length of the front part and the length of the rear part are adjustable by moving the cargo boom relative to the stand column; and a counterweight (12) movably connected to the boom (3). The boom (3) and the counterweight (12) are arranged such that they can move independently of each other, and the counterweight and the boom are arranged such that the counterweight can pass through the column and can move between the front portion (6) and the rear portion (8) independently of the position of the boom (3) relative to the column (2).

    本发明涉及一种起重机(1),包括:立柱(2);细长的起重臂(3),该细长的起重臂连接到立柱,该细长的起重臂具有在立柱的一侧上延伸的前部部分(6)和在立柱的相对侧上延伸的后部部分(8),起重臂(3)相对于立柱是线性可移动的,使得前部部分的长度和后部部分的长度通过起重臂相对于立柱移动起重臂是可调节的;以及配重(12),该配重可移动地连接到起重臂(3)。起重臂(3)和配重(12)布置成使得它们能够独立于彼此移动,并且配重和起重臂布置成使得配重可穿过立柱并且可独立于起重臂(3)相对于立柱(2)的位置在前部部分(6)和后部部分(8)之间移动。
