Abstract

The invention provides a crane, and belongs to the field of crane equipment. The crane comprises a main body assembly, a lifting hook assembly and a counterweight assembly; the main body assembly comprises a base column, a rotating column, a lazy arm and a driving rope, the lifting hook assembly comprises a lifting hook and a first rope, the counterweight assembly comprises a first pulley, a second rope and a counterweight frame used for placing a counterweight block, the first pulley is located at the top end of the rotating column, the first pulley protrudes out of the peripheral wall of therotating column, the first end of the second rope is connected with the top end of the lazy arm, the second end of the second rope penetrates through the first pulley to be connected with the counterweight frame, and the counterweight frame is slidably located on the outer wall of the rotating column in the axial direction of the rotating column. According to the crane, the counterweight block can be placed on the counterweight frame, so that the weight of the lazy arm can be counteracted, and the inclination angle can be adjusted by providing less energy consumption when the lazy arm does pitching motion.

Description

technical field [0001] The disclosure belongs to the field of crane equipment, in particular to a crane. Background technique [0002] Cranes are commonly used equipment in workshops, ports, construction sites and other production sites, used to lift heavy objects to achieve the purpose of transportation. [0003] When transporting different heavy objects, it is necessary to adjust the inclination angle of the boom, that is, to control the pitching movement of the boom. In the related art, the pitching motion of the boom is usually realized by arranging components such as a high-power motor, a reducer, and a cooler. [0004] However, the above-mentioned method for realizing the pitching motion of the boom will greatly increase the energy consumption of the crane, thus resulting in a substantial increase in the production cost of the crane. Contents of the invention [0005] The embodiment of the present disclosure provides a crane, which can counteract the weight of the ...
