    摘要: A self-propelled drive mechanism for a crawler crane or the like including a variable displacement pump and one fixed and one variable displacement motor for each crawler assembly. The displacement of the variable displacement motor may be regulated to alter the combined driving torque and speed imparted by the motors to the crawler assemblies and includes automatic self-balancing feedback means for maintaining the hydraulic pressure within predetermined limits.
