Check item bridge crane safety inspection in order to ensure the safe operation of the bridge crane, crane operation required during some routine security check on the project and points are as follows: (1) lifting height limiter, travel limit switches and various interlock mechanism normal performance, safety and reliability. (2) comply with the safety requirements of the main components: an opening to increase less than 15% of the original size, the torsional deformation of less than 10%; plate hook bushing wear less than 50% of the original size, the board hook spindle wear less than 5%, no peeling , burrs, welding. Hanger hooks and pulleys no obvious defects. Wire rope surface abrasion, corrosion of less than 40% of the diameter of the wire, broken wire in a twist pitch in less than 10% of the total number of wires, no breakage, no significantly thinner, crane flower, no core prolapse, dead twisting, extrusion, annealing, burning phenomenon. Rope end connections and fixing clips, clips, wedge block connection intact, crawler cranes, no loose, plate no less than two, no less than three catches. Roll no cracks, connections, fixed no loose; wear tube wall thickness of less than 20% of the original; secure volume of not less than two laps, drum and rope diameter ratio meets the requirements. Balance wheel fixed intact, rope shall comply with the requirements. Brake no cracks, no loose, no serious wear, brake clearance on both sides equal right size, there is sufficient braking force, the brake band wear less than 50% of the original thickness. By conventional overhead crane safety inspection, to prevent personal injury to reduce equipment accidents, improve equipment operation rate, reduce maintenance costs etc played a significant role. Corrugated web crane has the following advantages: 1 corrugated web crane machine, light weight, small wheel pressure, Lu new cranes, can reduce stress steel plant; 2 flat web thickness is generally a high degree of member 1/80. , while the corrugated web due to the increase in the corrugated web of reduced thickness requirements, corrugated web thickness may be highly 1/500 member, save steel 25% to 40%, while the small increase in production costs; 3. Corrugated representing an increase of stiffener web itself, improve the stability of web force, improve the ability of the shear section;. due to the reduced amount of steel, but also a corresponding reduction in the demand for energy member 4, saving resources protect the environment; 5. corrugated web cranes compact body, the overall small size and efficient for customers to save the plant spatial dimensions; 6. Crane corrugated web using digital intelligent electrical control system, Sherwin cranes, smooth running, low noise reduce energy consumption; 7 corrugated web cranes look beautiful, aesthetically pleasing visual. 8. The most important thing is its price and the price compared to the traditional bridge crane, a substantial increase in cost. 9. The whole weight than traditional light bridge crane around 27% to 35%; Luxin crane crane _ _ Sherwin heavy generous generous by heavy machinery Co., Ltd., Henan Province.
