Safe operation is the basic guarantee for the self feeding mixer to complete its work tasks, and also a reliable guarantee for the operation and maintenance of the self feeding mixer and the personal safety of surrounding construction personnel. Next, we will talk about the precautions for safe operation of the self feeding mixer.
Check whether there are sundries stacked on the vehicle body. Focus on checking the liquid level and leakage of diesel, engine oil, various gear oils, various booster oils, engine condensate and brake fluid.
During transportation, the self feeding mixer shall operate at a slow speed of 3-6 rpm. During normal mixing driving, the high speed shall not exceed 50km/h. Don't turn too fast, and the turning speed is not more than 15km/h, otherwise there will be a danger of rollover. The empty speed shall not exceed 60km/h. When the slump loss is too large, the appropriate amount of water can be added under the condition of meeting the requirements of the design mix proportion of concrete. This work must be completed by the laboratory technicians. In addition, it is prohibited to add water to the mixing tank.
After the concrete is transported to the site, the person in charge of the construction site shall unload the concrete in turn. The unloading shall be clean to avoid waste. The tank of the feeding mixer shall be cleaned in time to drain the accumulated water. The driver shall maintain the self feeding mixer frequently to ensure the service life and normal operation of the mixing tank truck. The supporting wheel oil nozzle shall be filled with high-pressure grease once a week, and the supporting wheel track shall be filled with a little graphite or molybdenum sulfide grease every shift.
During the maintenance of the mixer, the power supply must be cut off. If it is necessary to enter the drum for maintenance, the wooden sign of "No switching on" must be hung on the electric switch, and a special person must be assigned to watch over to ensure that the power supply accident can be avoided.
After the production is stopped, the inside and outside of the tank shall be cleaned in time to prevent concrete bonding. After the work is completed, the hopper shall be lifted to the top position and fastened with safety hooks; Pull off the switch and lock the switch box before leaving the site.
In addition, the water in the water pump, drain switch and water storage tank must be drained after the work in cold season to avoid freezing the equipment. You can come to our website at any time for more relevant major matters https://www.zishangliaojiaobanji.cn Ask about it!
