摘要： PURPOSE: A parking brake device of a skid steering loader is provided to prevent damage even though the parking brake device is operated during traveling of a car, and to brake the car at the time of traveling of the car. CONSTITUTION: A parking brake device of a skid steering loader includes an axle shaft, a brake housing(20), a number of brake discs, a number of friction plates, a brake piston(30), a solenoid hydraulic control valve(50), and an operation switch(60). The brake discs are separated from each other at predetermined intervals along the axle shaft and rotated integrally with the axle shaft. The friction plates are arranged among the brake discs and movably assembled on an inner circumference of the brake housing. The brake piston is pressed in a direction for contacting the brake discs and the friction plates by a pressing spring and pressed in a direction for separating the brake discs from the friction plates by pressure oil. The solenoid hydraulic control valve is selectively introduced to the brake housing. The operation switch supplies or blocks current to or from the solenoid hydraulic control valve.

摘要： PURPOSE: A tool holder for a breaker is provided to reduce the noise generated during percussion, to guide a chisel exactly and to returns the chisel to the original place automatically. CONSTITUTION: In a front head(20), the inside-diameter-part is formed downward. A chisel bush(26) is inserted in the upper end of the inside-diameter-part of the front head, and guides a chisel up and down. A cylindrical front-bush(28) is inserted in the lower end of the inside-diameter-part, and guides the chisel up and down with the chisel bush. The cylindrical front-bush also limits the downward move of the chisel. The chisel has a tapered part(22b) within a percussion range. A cylindrical stopper bush(34) is made of rubber, and installed between the chisel bush and the front bush. The stopper bush is tapered to correspond to the tapered part.

摘要： PURPOSE: A breaker is provided to increase the ascending speed and hitting force of a piston without increasing the entire rated voltage by installing a piston accelerator. CONSTITUTION: A cylinder conversion chamber(11) is interlocked with a cylinder low voltage chamber before a piston(4) hits a chisel(6). A valve conversion chamber of a control valve(5) is converted to a low voltage state so that a valve body(14) is moved to a lower part, and the piston hits the chisel(6). When the valve body drops, an upper partition chamber(8) becomes the low voltage state, and a piston unit(34) of an accelerator(30) is moved to a lower part. Then, the pressure in a gas chamber(13) is kept in an initial state, and an upper end of the piston returns to the volume of the gas chamber and an original state. When the breaker becomes the initial state, the piston ascends in a moment and reciprocates. The chisel is hit so that a crushing action is performed. The supply of compressed oil is blocked in order to stop the crushing action.
摘要翻译：目的：提供一个断路器，通过安装活塞加速器来增加活塞的上升速度和击打力，而不会增加整个额定电压。构成：在活塞（4）撞击凿子（6）之前，气缸转换室（11）与气缸低压室互锁。控制阀（5）的阀转换室转换为低电压状态，使得阀体（14）移动到下部，并且活塞撞击凿子（6）。当阀体下降时，上分隔室（8）变为低压状态，并且将加速器（30）的活塞单元（34）移动到下部。然后，气室（13）中的压力保持在初始状态，并且活塞的上端返回到气室的容积和初始状态。当断路器变为初始状态时，活塞瞬间上升并往复运动。凿子被击中，以便进行破碎作用。压缩油的供应被堵塞以停止破碎动作。
