(1)、起重机麻绳使用前必须认真检查、若发现有黄斑应降级使用。有鼠尿的禁止使用,做千斤绳时,麻绳的负荷不许大于使用拉力。 (2)、麻绳一般用于重量较轻的物体的捆绑,吊装及桅杆。四川起重机厂-成都泰力编辑. (3)、用于滑车式滑轮组的麻绳所承受的附加弯曲及磨损,滑轮 的直径应比麻绳直径大10倍以上,绳槽的半径应比麻绳的半径大四分之一。 (4)、使用中,如果麻绳有扭曲时,应设法抖直,以免损伤麻绳的内部纤维,不容许麻绳在尖锐或粗糙的物体上拖拉,以免降低麻绳的强度,短缩使用寿命。 (5)、在捆扎物件时,应避免麻绳直接与物件尖锐处接触处须与麻袋或木头等衬垫。 (6)、旧麻绳表面均匀磨损不超过直径百分之三十,局部损伤不超过直径的百分之十。 (7)、麻绳不宜在腐蚀作用的化学物品(如酸、碱)的地方使用。存放应在通风良好干燥的地板上,不要受潮湿烘烤。 (8)、新麻绳开卷使用,应按缠绕方向展开,使用绳头的一端放在下面,从卷内拉出绳头,以免打结。 (9)、编结麻绳时,拧松的长度约为麻绳直径的10倍左右,每个麻绳要求穿压三花以上偏按长度在20~30厘米为宜。以上基本概述麻绳使用中的技术规范望切记避免事故发生。 Hoisting machinery rigging including: hemp rope, steel rope.

(4), in use, if there is a twisted rope, should try to shake out straight, in order to avoid damage the interior of the hemp rope fiber, does not allow hemp rope drag on sharp or rough objects, so as not to reduce the strength of the hemp rope, shortening life. (5) in the case of binding objects, the hemp rope should be avoided directly with the incisive contact between the object and the material, such as a sack or wood. (6) the surface uniform wear of the old hemp rope shall not exceed 30% of the diameter, and the local damage shall not exceed 10% of the diameter. (7) the hemp rope should not be used in the corrosive chemical substances such as acid and alkali. Storage should be in a well-ventilated, dry floor, not wet roasting. (8) the new hemp rope should be opened in a winding direction. The end of the rope head shall be placed below, and the rope head shall be pulled out from the inside of the paper to avoid the knot. (9) when the rope is arranged, the length of the unscrewing is about 10 times the diameter of the hemp rope, and the length of each rope shall be 20 ~ 30cm in length. The above basic overview of the technical specifications in use of hemp rope is to avoid accidents.
