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.

为了实现Interlock的目的，将滑离奇设备应用于码数，由于缺乏简单，廉价且有能力的互联网码头，其在日本的技术一直在国外落后，这是如何根据两个鼓的旋转方向来简化互锁装备的变化。为了回应其期望，我们开发了一个简单且自动实用的设备的Drk（dixialreibungskupplung）的院子，用于其齿轮的变化，其最近构想的合适原理仅基于常规的外国昂贵的昂贵的昂贵的空运缸，其较小的缩放机械机制。另外，此外还引入了静液压传播，以缓解操作员在驾驶中的麻烦。工厂基本测试的结果：总是完美地保证了原始设备的原始设备的基本功能。因此，当必须将操作线保持在旋转鼓的方向上独立于某个张力中时，该设备似乎将被广泛应用于其他目的。 b。 DRK控制的稳定性取决于DRK的内部结构，当它用四个单独的垫子中的裸露圆盘类型中的结构制成时，可能会继续前进。记录操作中的现场测试结果：由DRK组成的DRK-EquipMeat和用于齿轮变化的设备的效果非常出色。 b。与其他院子相比，院子的运行效率足够高。 c。在操作过程中，DRK中产生的摩擦热并不是任何强制冷却，尽管它连续使用。 d。操作员的麻烦和身体负担确实按预期减轻了。
