GINDIN: продукция Drumet (Друмет) в России

Ropes not lubricated may contribute to considerable shortening of driving drum life, as well as of rope life. It is good for lift ropes to re-lubricate them during operation. Higher temperature, high rope speeds, small bending radii dry the rope and remove factory applied lubricants. Lubricant is not applied for rope life. Proper lubrication of load-carrying ropes increases rope life by reduction of rubbing between rope wires and strands, as well as it delays core damage by elimination of rope deterioration. Also, lubrication reduces the wear of sheaves. To maintain optimum rope life, it is recommended to re-lubricate them properly, in addition to other maintenance activities required by the regulations. DRUMET recommends, for example, "UNOLIT SPRAY OIL" from the German Company DEA ELASKON in Dresden ( www.dea.de ) or "NYROSTEN Seioil Compound" produced by the German Company Nyrosten in Geldern ( www.nyrosten.de ) or similar lubricating agent intended for lift ropes. Way of rope maintenance Both lubricants mentioned above are intended for lubrication and maintenance of lift, overhead crane, crane and cable railway ropes. They feature with very good lubricity, quick application and good penetration between rope wires, effective protection against corrosion and excellent adhesion. The lubricants may be applied with the use of a brush, roller or by spraying. The lubricant shall be applied on clean and dry crane rope. It seems that the most adequate and efficient method of lubricant application is to use the roller fitted to the original lubricant bottle with the scale on its side, keeping the bottle bottom up. It is easy to observe proper volume of lubricant applied after touching the moving rope with the roller. Recommended lubricant volumes Re-lubrication of ropes: Put approximately 1 litre of the lubricant on the rope section shown in the table below. Rope diameter [mm] Rope section length [m] 10 400 12 310 16 200 18 150 For example, 4 x 43 m /310 m = approximately 0,55 litre of lubricant shall be used for typical set of 4 rope sections, 43 m each, rope diameter 12 mm, however, in accordance with the rule of more frequent re-lubrication with smaller lubricant quantity, it is recommended to use 0,4 – 0,5 litre of lubricant, that is approximately 100 - 125 ml per each rope section. After re-lubrication, sheave grooves should give the feeling of slight oily moisture or a streak in the inspector ’ s finger. No slight oily moisture at sheave grooves together with the presence of chips and dirt in the grooves indicates that cleaning and lubrication is required. Few rules of proper maintenance of Lift ropes Perform maintenance activities before the rope is dry or corroded Use lubricants recommended for crane load-carrying ropes Lubricate crane load-carrying ropes, lubrication of other ropes is not recommended Do not mix different types of lubricants together Excess of the lubricant may cause loss of rope properties, rope slipping and/or other unpredictable events (loss of frictional properties). Rope slipping, when accelerating or braking, may indicate lubricant excess Non-observance of recommendations specified above may be a cause of serious problems and/or accidents at work leading to serious injuries or death NOTE: Observance of the rules specified above does not release from compliance with the regulations for passenger and goods lifts, especially with the rules established by proper Technical Inspection Offices and/or suppliers or designers of lift parts. Therefore, the DRUMET Ropes and Wires sp. z o.o. is not responsible for correctness of lubrication rules specified above for specific application and possible damage to life, health and property, which may arise as a result of the use of those rules.
