Applying the slip-clutch apparatus to the yarder for the purpose of the inter-lock, whose techniques in japan have been behind the foreign countries because of lack in the simple, cheap and capable yarder of interlock, the essential problem is how to simplify the change of the interlocking gear according to the rotative direction of the two drums. In response to its expectation we developed a yarder of DRK (Differentialreibungskupplung) with a simple and automatically functional apparatus for its gear change, whose recently conceived suitable principle is merely based on the small scaled mechanical mechanism, unlike the conventional foreign expensive air-shift-cylinder. In addition a hydrostatic transmission was also introduced in this yarder to ease the trouble of the operator in driving.A. The results of the basic tests in the factory: a. The fundamental function of the original apparatus for gear-change was always perfectly assured. Therefore it seems that this apparatus will be applied to the other purposes widely when the operating lines must be kept each other in a certain tension independent on the directions of the rotating drums. b. The stability of DRK-control depended on the inside structure of DRK and could continue enough when it was made of structure in exposed disc type with four separate pads.B. The results of the field tests in logging operation: a. The effect of the DRK-equipmeat composed of DRK and the apparatus for gear-change was remarkable. b. The operational efficiency by the yarder was higher enough comparing with that by the other ones. c. The frictional heat generated in DRK during operation was not so much as any forced cooling was besides required, in spite of its continuous use. d. The trouble and the physical burden of the operator were really lightened as expected.

将滑动离合装置应用到成卷机上实现联锁，日本由于缺乏简单、廉价、功能强大的联锁成卷机，其技术一直落后于国外，关键问题是如何简化联锁装置。根据两个滚筒的旋转方向改变联锁齿轮。为了满足其期望，我们开发了一种DRK（Differentialreibungskupplung）调幅机，其具有简单且自动功能的变速装置，其最近构思的合适原理仅基于小型机械机构，而不像传统的国外昂贵的空气变速装置那样。圆柱。另外，该堆码机还采用了静液压传动装置，减轻了操作者驾驶的麻烦。工厂基本测试结果：a．原始变速装置的基本功能始终得到完美保证。因此，当操作线必须彼此保持一定的张力而与旋转滚筒的方向无关时，该装置似乎将广泛地应用于其他目的。 b. DRK控制的稳定性取决于DRK的内部结构，当其采用带有四个独立焊盘的裸盘式结构时，可以足够持续。测井作业现场测试结果： a．由DRK与变速装置组成的DRK装备效果显着。 b.与其他堆场商相比，堆场商的作业效率足够高。 c.尽管连续使用，DRK 在运行过程中产生的摩擦热并不多，除了需要强制冷却之外。 d.果然减轻了操作者的麻烦和体力负担。
