QLZ direct screw opening and closing machine with multiple models for customers to choose from

The manufacturer provides multiple models of QLZ direct screw opening and closing machines for customers to choose from

The direct coupled screw hoist is suitable for opening and closing various flat gates with downward pressure requirements. Its characteristics are compact structure, fast opening and closing speed, good reliability, strong resistance to damage, small installation area, easy operation, and convenient maintenance. It has a certain forced gate downward pressure and is not suitable for long-term overload and continuous operation.

The working principle is that when starting electrically, the power is transmitted from the motor to the worm gear through the gearbox. The worm gear and worm wheel drive the nut to rotate, thereby achieving the up and down movement of the screw. The screw and gate are hinged to achieve the opening and closing of the gate. In addition, there is a control lever inside the gearbox, which can separate and connect the motor and worm gear. When manually operated, the crank directly drives the worm gear to drive the worm gear and nut to rotate, achieving the up and down movement of the screw and gate. When manually operated, the entire machine can be powered off through the flashlight interlock device.
