  • Hoist device with leveling and disengagement mechanism
    Patent number: 8424938
    Abstract: A hoist device with leveling and disengagement mechanism mainly comprises a stand under traditional hoist, a plural number of branches on the stand extending radially outward, a plural number of driving modules 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 signal, a control circuit that can output control signals to control each driving module while each sensing module can sense the status of each driving module and feedback to the control circuit to correct the output control signals, allowing each driving module on the stand to level and disengage the hung object, and enabling the hoist to lift the hung object.
