Concrete safety rules

Concrete safety rules 1, concrete pump should be placed on a flat, solid ground, surrounded not have obstacles in the legs down and adjusted so that the body should be level and stable, the tire should wedge 2, sand grain size, grade and mix cement factory 800l twin-shaft force concrete mixer sanfan products should be specified to meet the pumps can pump requirements. 3, before the job should check that the pump ministries bolts, guards complete and reliable, each part of the operation switch, adjust the handles, hand wheels, levers, cocks are on the correct position, the hydraulic system is normal no leakage, hydraulic oil accord It provides no debris stirred infighting, the top protection grid intact and reclosable. 4, the wall thickness of the pipeline and pumping pressure should be matched at near pump tube should be of high quality. Pipe joints, seals and elbow, etc. should be intact. Sun should be used at high temperatures or wet wet sacks straw bags cover piping, and timely watering cooling, insulation measures should be taken to the cold season. 5, should be equipped with cleaning pipes, portable hzs50 concrete mixer plant with cement silo cleaning supplies, ball control and related devices. Before pump, unrelated persons should leave around the pipe. 6, after the start, should the no-load operation, observe the functioning of the indicated value of each instrument, check the pump and a stirring device, make sure everything is normal only after the operation. Hopper should be added before pumping 10L, water and cement mortar 0.3m3 lubrication pump and piping. Concrete pump debug conditions include: 1. Concrete pump test prototype components, accessories and tools should be required to fully equipped random. 2. ready hydraulic oil and grease, oil hydraulic oil should be specified. 3. Fill the required hydraulic oil, fuel oil, lubricating oil and cooling water. Hydraulic oil is added to the provisions of the oil surface. 4. Test the concrete should be specified. 5. Test the prototype should be placed on a flat solid ground. 6. Before checking respond eco friendly js1000 double shaft clay concrete mixer prototype test, commissioning and commissioning, to make it into the normal working state, after the commissioning of the hydraulic system should be specified. 7. Experiment with concrete pump piping diameter is 125.
