Line hanging job jog performance checks mainly for line hanging job during hoisting, slewing, luffing mechanism of action sensitivity and accuracy for debugging. Line hanging debugging requirements: when the relevant agencies to ensure that the lifting operation smooth, accurate operation, no creep, vibration, shock and driving power increases and other abnormal phenomena: lifting, jogging good performance slewing, and luffing mechanism. Debugging conditions: basic boom, boom elevation angle 50 °, lifting the rate of work under the rated lifting capacity to stop after one meter height. Debugging methods: pulling the joystick to the crane (down) position, when the weight as soon as the slightest movement brake. Continuous landing boom 10 times 20 tons of traffic, measured horizontally moving heavy objects accumulated distance, and calculate the average per-action arm landing shift amount. Its value should meet the specified value, or should be adjusted brake reliability and sensitivity (wire luffing mechanism) or the back pressure in the hydraulic circuit balancing valves and secondary safety valve set pressure (hydraulic cylinder luffing). Hanging on the line, "universal" brake stopper daily use will make the line hanging device response to some dull eight tons of traffic, which is why? I believe we will encounter such a problem, just as my phone 10 tons of traffic, will be a long time to use crash, the card machine phenomenon, the key is to design issues coupled with low hardware configuration reason, it is recommended that you purchase line hanging device be sure to choose well-known brand, the brand trusted. Operator error due to an accident or heavy machinery equipment in daily use caused some people notice some glitches occurred in daily use the process to take a free to ignore this, if prolonged will lead to major equipment accident was In the wear process can not estimate late. For the crane safety management system running safely and reliably, the mechanical brake is necessary to function effectively, elastic appropriate, necessary in the absence of electric braking conditions outside help, can drop to the rated load at full speed and reliable braking. SCM central disposal system, real-time status and position information gathering work of the master switch, the central processor via the control unit for disposal information traffic, use 485 to achieve information from the control unit to the execution unit of transmission, thus completing crane size control motor vehicles, thus achieving Crane left to front right and shift information and car control, rear and gear information. 15 tons of traffic, generous heavy (certified), Luliang driving by heavy machinery Co., Ltd., Henan Province, generous. Heavy Machinery Co., Ltd., Henan Province, generous (www.hnqizhongshebei.com) (www.hnqizhongshebei.com) is Zhengzhou, engineering, construction cranes leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. In heavy generous leadership with the staff warmly welcome all inquiries negotiations to create a better future for heavy generous.
