Abstract

The invention discloses a slewing crane provided with a spiral arm slewer. The slewing crane comprises a base and a belt, wherein a support seat is arranged at the top of the base; a stand column is fixedly connected with the top of the support seat; a rotary arm is movably connected with the top of the stand column; an equipment box is fixedly connected with the left side of the base; a motor isfixedly connected with the left side of the cavity of the equipment box; a first threaded rod is fixedly connected with the right side of the output end of the motor; and a second threaded rod is movably connected with the left side of the cavity of the equipment box and with the rear side of the motor. Through arranging the base, the support seat, the stand column, the rotary arm, the equipment box, the motor, the first threaded rod, the second threaded rod, a first belt pulley, a second belt pulley, a belt, a threaded sleeve, a connecting rack and a movable wheel, the problem that the existing slewing crane is lower in practicality is solved. The slewing crane has the advantage of being high in practicality and deserves popularization.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a jib crane with a jib turning device. Background technique [0002] A crane refers to a multi-action lifting machine that lifts vertically and carries heavy objects horizontally within a certain range. Equipment, unique structure, safe and reliable, with high efficiency, energy saving, time-saving and labor-saving, flexible and other characteristics, in the occasion of section distance and intensive transportation, it shows its superiority compared with other conventional lifting equipment, and is widely used in various industries different places, but the existing jib cranes are poor in practicability. The general jib cranes are fixed in one place for use. The jib length of the jib crane is certain. If the cantilever is too long, it will affect the crane Stability, so the operable range of the jib crane is small. At present, there is no mobile jib crane with slide rails, which ...
