堵转型液力偶合器是限矩型液力偶合器一个特殊型式，顾名思义，它是一种可以在零速工况（即堵转）使用的液力偶合器。下面通过塔式起重机卷线机构说明其原理和功能。由图1可见，塔机卷缆机构要求具备牵引、张紧、反转三种功能。当小车向左行驶时，电缆应当卷起，此时液力倡合器 Locked-rotor fluid coupling is a special type of torque-limiting fluid coupling, as the name implies, it is a fluid coupling that can be used at zero speed (ie, locked rotor). The following describes the principle and function of the tower crane winding mechanism. Can be seen from Figure 1, tower crane mechanism requires traction, tension, reverse three functions. When the car to the left, the cable should be rolled up, this time hydraulic advocate
