Description

technical field

[0001] The invention relates to a limit mechanism of a lifting device. Background technique

[0002] When the lifting device on the insulated bucket truck lifts the goods, it is generally operated manually. Due to the poor accuracy of the manual operation, it often encounters the situation of excessive winding. After excessive winding, the goods may hit the lifting device or the motor may overheat. cause danger. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a limit mechanism of the hoisting device, which can prevent excessive wire-rewinding during the hoisting device, and protect the safety of the cargo and the hoisting device.

[0004] In order to solve the above-mentioned technical problems, the present invention provides a limit mechanism of a lifting device, which includes two side vertical plates arranged opposite to each other on the left and right, and a rear vertical plate connecting th...
