The invention discloses a lifting crane and relates to the technical field of construction equipment. The lifting crane comprises a base. The base comprises a vehicle plate, a stand column and a motor. The middle part of the upper end of the right surface of the stand column is provided with two gear grooves. The middle part of the upper end of the front surface of the stand column is provided with a circular groove I. A rotary disk is arranged on the lower surface of the stand column. The lower end of the rotary disk is hinged to the middle part of the upper surface of the vehicle plate. Theoperating direction of the crane is changed through rotation of the rotary disk, and the working range is expanded. The motor is used for driving a rope reel to rotate to lift up or lay down an article. A rope is protected against disturbance of long poles through a rope ring. A rotary rod is rotated to drive a gear II to drive a gear I to rotate to change the position of the long poles, so that the inclination angle of a slanging pole is controlled, and the hoisting height of a crane boom is changed. Thus, the lifting crane can hoist cargos to different heights.
本发明公开了一种可升降起重器,涉及建筑设备技术领域。该一种可升降起重器,包括底座,底座包括车板、立柱和电机,立柱的右表面的上端中间部分设置有两个齿轮槽,立柱的前表面的上端中间部分设置有圆槽一,立柱的下表面设置有转盘,转盘下端与车板的上表面中间部分铰接,通过转盘的转动来改变起重机的工作方向,扩大了工作范围,通过电机带动绳盘转动来拉起或放下物件,绳圈保护绳索不受长杆的干扰,转动转杆,使得齿轮二带动齿轮一转动,改变长杆的位置,从而控制斜杆的倾斜角度,从而改变起重架吊取的高度,使该起重器可将货物吊至不同高度。
