The electric head hoist is an electromechanical integrated fully sealed structure, suitable for outdoor work, and adopts worm gear transmission. Equipped with travel limit and torque protection devices, the travel limit device consists of a set of counting gears and hard contact limit switches. When the gate is opened or closed in place, the counting gear drives the travel limit rod, causing the hard contact limit switch to work and automatically stop the gate opening and closing action. When the torque increases due to some reason, the torque protection switch will act to protect the opening and closing device from accidental damage. A pointer type opening indicator and heating resistor are separately designed on the electric device. The pointer type opening indicator is connected to the counting gear, which can intuitively reflect the opening position of the gate. The heating resistor is automatically connected during the operation of the opening and closing machine to remove moisture from the electric device, ensure internal dryness, and ensure the reliable operation of various electrical components. The opening and closing nut and the output end of the electric device use a tooth embedded connector. The claw of the tooth embedded connector has a gap, which creates a hammering effect at the moment when the gate is opened, achieving the purpose of hammering start and increasing the pre lifting force when the gate is opened and closed. The cast iron support is a closed structure used to withstand the gravity or reaction force when opening and closing the gate. It is equipped with load-bearing bearings and has a beautiful appearance. It can be controlled both on-site and remotely. Manual and electric automatic switching.
