Safety operation procedures of concrete pump truck?

1. Use of automobile chassis, internal combustion engine, air compressor, water pump, hydraulic device, etc. , constitute a concrete pump truck, should comply with the general provisions of the car and the relevant provisions of the concrete pump. Second, the position of the pump truck should be flat and solid, with no obstacles around and no high-voltage transmission lines above. Pump trucks are not allowed to stop on slopes. Three, pump truck in place, should set up the leg and keep the fuselage level and stability. When the boom is used for feeding, the inclination of the fuselage shall not be greater than 3. Four, in place, the pump truck should turn on the stop light, to avoid collision. 5. Before operation, the inspection items shall meet the following requirements: 1, fuel, lubricating oil, hydraulic oil and water tank shall be fully filled, tire pressure shall meet the requirements, and lighting and signal indicators shall be complete and good; 2. The hydraulic system works normally, and the pipeline has no leakage; Cleaning pump and equipment are complete and good; 3. There is no sundries in the mixing hopper, and the protective net on the hopper is intact and tightly covered; 4. The pipeline is firmly connected and well sealed. 6. The pipes and hoses used for pipe laying shall be selected according to the specifications of the manufacturer, and pipes with diameters exceeding the specified diameter shall not be used. The connected hoses shall be fastened with non-slip safety belts. Seven, telescopic boom should be carried out in accordance with the order of the factory instructions, boom can only be rotated after rising from the bracket. It is forbidden to use the derrick to lift or drag objects. Eight, when the boom is fully extended, the car body shall not move. When it is necessary to move the car body during operation, the upper boom should be folded and fixed, and the moving speed should not exceed10 km/h. Do not drag the front hose of the boom on the ground. It is forbidden to extend distribution pipes and suspenders. When the wind reaches level 6 and above, the placing boom shall not be used to transport concrete. Ten, the laying of pumping pipeline, should be carried out in accordance with the provisions of article 2 of this regulation of concrete pump. Eleven, before pumping, when the temperature of hydraulic oil is lower than 65438 05℃, the method of extending idling time should be adopted to improve the oil temperature. Twelve, when pumping should check the operation of the pump and mixing device, monitoring instruments and indicator lights, found abnormal, should stop processing in time. Thirteen, the concrete surface in the hopper should be kept above the center line of the mixing shaft. Fourteen, pumping concrete should be continuous operation. When forced to suspend due to the interruption of feeding, it shall be implemented according to the requirements of Article 10 of this regulation for concrete pumps. 15. During operation, the grating on the hopper shall not be removed, and the unqualified aggregate or sundries shall be removed in time. Sixteen, found in the process of pumping pressure gauge rose to the highest value, running sound changes, should immediately stop pumping, with reverse operation method to eliminate pipe plugging; If it is ineffective, the test tube should be taken out for cleaning. 17. After the operation, all the concrete in the pipeline and hopper should be discharged, and then the hopper and pipeline should be washed. When flushing the pipeline with compressed air, it is forbidden to stand in front of the outlet end of the pipeline 10m. Eighteen, after the operation, shall not use compressed air to flush the placing boom pipeline, placing boom folding contraction must be carried out in accordance with the prescribed order. 19. After the operation, reset the operating switch, adjusting handle, handwheel, control lever and cock of all parts, unload the hydraulic system, retract the leg, park the car in a safe place and close the doors and windows. Water should be stored in winter.
