Abstract: A training machine of load force simulation has a damping unit comprises a press cylinder which includes a cylinder, a movable piston rod, and a press source; a controller is coupled to the press source of the damping unit and a load cell for calculating and controlling the load value of the load cell, allowing the elevating and lowering of a pulley system thereof by adjusting the damping force via the piston rod. Also, the pulley system comprises a plurality of movable pulleys to equally bear the load force from the rope, saving the efforts for operating and retarding the retrieving force of the rope for safety. The present invention is therefore able to replace complex decelerating machines and massive weight blocks in apparatus suchlike with features of small volumes as less space needed, less noises, and no restrictions of setting areas due to no need of electricity.
