为提升起重机吊臂伸缩平顺性,找出影响的关键因子,特提出一种切实可行的提升吊臂伸缩平顺性的新思路。大量的试验证明在诸多影响因素中,从滑块上入手解决吊臂伸缩平顺问题是一种切实有效的方式。本文提出了使用高分子聚乙烯和改性聚甲醛材质的滑块代替当前普遍使用的MC尼龙滑块,取得了良好的效果,为解决起重机伸缩式吊臂伸缩平顺性提供了一种的新思路。 In order to improve the telescopic boom of crane crane and find out the key factors affecting the crane boom, this paper proposes a new idea to improve the ride comfort of crane boom. A large number of tests prove that in many influencing factors, starting from the slider to solve the telescopic boom is a practical and effective way. This paper presents the use of polymer polyethylene and modified polyformaldehyde slider instead of the commonly used MC nylon slider, and achieved good results, in order to solve the crane telescopic telescopic boom provides a new idea .
