What are the precautions for maintenance and upkeep of gate opening and closing machines

Do not lubricate the steel wire rope while the hoist drum is rotating; During the homework period, there should be a dedicated person monitoring the upper part of the hoist room or gate opening; When working in the door slot, measures should be taken to prevent tools and components from falling into the door slot to prevent the gate from getting stuck; Check and clean the water stop of the gate body. When oiling the support hinge of the fixed wheel side arc door, personnel should wear safety belts, anti-skid shoes, and have a dedicated person supervise; When maintaining the transmission mechanism such as the open gear reducer coupling of the opening and closing machine, the operators should command and coordinate in a unified manner to avoid crushing and injuring fingers. After the operation is completed, the protective cover should be installed properly and not damaged.

When installing the screw hoist, it is necessary to ensure that the base is placed parallel to the horizontal plane at 240 °; The contact area between the base of the gate opening and closing machine and the parallel surface of the base should reach more than 90% of the ground; The centerline of the screw should be perpendicular to the inclined plane considered on the gate platform; To ensure stability and verticality with the lifting ear holes of the gate, it is necessary to prevent the screw from tilting and forming partial support reactions that may damage the parts. The calibration steps for screw type opening and closing devices require a solid and safe foundation for the gate opening and closing machine.

The concrete for the axle seat and foundation structural components shall be poured according to the requirements of the construction drawings. When the concrete rebound does not reach the planned compressive strength, it is prohibited to dismantle or modify the temporary support points of the gate opening and closing machine, and trial extraction and operation shall not be carried out. Place the semi-automatic screw hoist in the device position. How to place the limit switch panel on the screw, screw the screw from the bottom of the top beam into the equipment, and then place the limit switch panel when the screw is above the equipment. Directly below the screw and connected to the gate.
