The invention provides an automatic leveling device on a crane. The automatic leveling device comprises a first lifting mechanism, a first lifting hook, a first absolute value encoder, a second lifting mechanism, a second lifting hook, a second absolute value encoder, a controller, a leveling button and a brake button. The absolute value encoders are used for accurately positioning the height of the lifting hooks, then a fixed-point height is set through the controller, and the two lifting hooks are moved to the fixed-point height. The automatic leveling device has the advantages of being simple in structure, ingenious in design, capable of rapidly and accurately leveling the lifting hooks, time-saving, labor-saving and the like.
本发明提供了一种起重机上自动调平装置,其包括有第一起升机构、第一吊钩、第一绝对值编码器、第二起升机构、第二吊钩、第二绝对值编码器、控制器、调平按钮和制动按钮,其通过绝对值编码器精准定位吊钩的高度,再通过控制器设置一个定点高度,将两个吊钩都移动至定点高度。本发明具有结构简单、设计巧妙、能够快速精确调平吊钩、省时省力等优点。
