The invention discloses an electric hoist. The electric hoist comprises an operating rod, a PLC control module, a motor and a hanger. The working modes of the electric hoist include a manual mode anda suspending mode; under the manual mode, an operator controls a handle to control operation of the motor, so that the hanger is controlled to move downwards or upwards; and under the suspending mode,the operator upwards pushes or downwards pulls a workpiece hung on the hanger to control operation of the motor, so that the hanger is controlled to move downwards or upwards. The electric hoist hasthe manual mode and the suspending mode. An operator flexibly controls the electric hoist conveniently according to different conditions of a site, so that working efficiency of the operator is improved. The electric hoist disclosed by the invention further solves the problem that grounded bounce appears while unloading is performed under the suspending mode.
Description
technical field [0001] The invention relates to the technical field of electric hoist control, in particular to an electric hoist and a control method thereof. Background technique [0002] At present, the hanging system has been widely used in the fields of industrial production and stage lighting. In the suspension system, the electric hoist is a commonly used equipment. Electric hoist is a common small-scale hoisting machinery driven by electricity, and the moving trolley can also lift and transport items along the straight track or curved track of the I-beam, so the electric hoist is often used as a single-girder bridge crane , Gantry cranes and cantilever cranes supporting lifting devices. [0003] The traditional electric hoist generally uses the operating handle as the control part of the electric hoist. However, when the operator cannot hold the handle due to too large workpiece or other reasons, the traditional electric hoist has great defects in use and cannot me...
