Abstract:

The key technologies of winch strypped-down of walking tractor were discussed. The collectivity kinetics of winch was analyzed. A method for calculating powers of winch was proposed．According to the worst working condition，the hoist power and the load up power were calculated，the larger power witch had definite over loading capacity between two powers was selected．The larger power was used to be gist to select the mainframe of JS3-2 winch．The constitution，working principle and main technical parameters of JS3-2 winch were introduced. Performance of JS3-2 winch was analyzed. The application of JS3-2 winch in production was expounded. Practice proves that JS3-2 winch has advantages of logical power matching，excellent performance and humanity manipulation. JS3-2 winch is applied widely in many disciplines，such as logging and transport of wood，road and bridge，irrigation work and electric power engineering，and so on.
