Patent ID: 8424938

Claim:
A hoist device with leveling and disengagement mechanism comprises at least: a stand with a plural number of branches extending outward radially; a driving module installed on each branch of the stand and being able to connect to a hung object; a plural number of sensing modules on each driving module to sense the operation status for each driving module and continue to output corresponding sensing signals; a control circuit via signal wires connecting to the sensing module and the driving module and at least comprising a digital/analog converter, an analog/digital converter and a processing unit; wherein the processing unit outputs digital control signals, which via a digital/analog converter are converted into analog control signals that will via signal wires control the operation for each driving module, wherein the sensing module at least comprises a pressure sensing component, a flow sensing component and a displacement sensing component, wherein each sensing module detects the status of each driving module and generates a digital sensing signal, which via signal wires is converted by the analog/digital converter into an analog sensing signal and then feedbacks to the processing unit for correction of the output digital control signals, and each driving module on the stand levels and hoists the hung object.
