The safety rules and safety technology of the gantry crane operation must be met, and more attention should be paid to the matters that should be observed after the operation is completed. There are many drivers who are not afraid of problems, and the construction unit is asked to formulate a punishment system to achieve the effect of supervision. The safety rules and safety technology of the gantry crane operation must be met, and more attention should be paid to the matters that should be observed after the operation is completed. There are many drivers who are not afraid of problems, and the construction unit is asked to formulate a punishment system to achieve the effect of supervision. 1. Ring the bell and get up. Start up smoothly and accelerate from gear to gear. 2. When lifting the cargo for the first time in each shift, the cargo should be lifted 30 cm from the ground and then lowered to test the reliability of the brake before performing normal operations. 3. Strictly implement the 'Ten No Lifting' during operation (1) Do not hoist when the signal is unknown; (2) Do not hoist when the tonnage is unknown; (3) Do not hoist when overloaded; (4) Do not hoist when standing heavy objects; (5) Wire rope Do not hang if it is not vertical; (6) Do not hang if there is insufficient lighting at night; (7) Do not hang if lashing is not secure; (8) Do not hang objects that are buried underground; (9) Do not hang objects that will explode without safety measures, which may damage the machine Don't hang; (10) Don't hang in heavy rain, fog and strong winds above level 7. 4. The driver should send out signals (bells) in accordance with the following regulations during the operation: (1) When lifting and lowering cargo, and driving large and small vehicles; (2) When the construction hoist passes through an unclear place, the bell shall be continuously sounded; (3) ) When the gantry crane is approaching surrounding obstacles; (4) When lifting goods and approaching people; (5) In other emergency situations. 5. During the operation of the gantry crane, it is forbidden to use emergency switches, limit switches, anti-truck and other means Come and stop. 6. Gantry cranes are prohibited from overhauling during operation. 7. Gantry cranes are prohibited from staying in the air for long periods of time while suspending goods. When the gantry crane is suspending the goods, the driver and the hooker are prohibited from leaving their work posts. 8. When loading and unloading containers or other goods, you should pay attention to: (1) Check whether the packaging is firm and solid (2) After all the hookers exit the carriage, they can lift (3) When loading and unloading large steel plates or workpieces with sharp edges, use special clamps or special Tools. When lifting with a wire rope, a cushion must be placed between the hanging object and the wire rope. 9. When the voltage drops significantly or the power supply is interrupted, the main switch must be disconnected, and all the controllers must be set to the zero position. 10. Emergency measures for the sudden failure of the brake of the lifting mechanism. When the brake is found to be malfunctioning, when the warning signal is issued, the car is reversed, the lifting controller is set to the appropriate level, and this method is repeatedly used to drive the car Go to a safe place, and then put down the cargo. If the lifting mechanism cannot work at the same time as the brake fails, immediately cut off the main switch of the driver's cab to de-energize the brake electromagnet and brake the brake. 11. When working in the open air, when the wind If it is above level 7, the operation should be stopped. Items to be observed after the operation is completed 1. Open the gantry crane to the designated place, and drive the trolley to the span end of the gantry crane. Raise the hook and pull all the controller handles to the zero position. Cut off the main power supply. 2. Clean and wipe the construction hoist. 3 Lubricate and maintain as required. In the case of safe operation of the gantry crane, it is necessary to perform it efficiently to speed up the completion of the project, which will test the level of the driver. If you need easy-to-use lifting equipment, you can find a lifting manufacturer to cooperate.
