The present invention is generally directed to a take-up frame assembly that is adapted to maintain a conveyor belt under constant tension. The take-up frame assembly, in one embodiment, can include a fluid cylinder having a retractable piston. The piston is interconnected with a bearing mounted to a shaft supporting the conveyor belt. The fluid cylinder includes a fluid regulator which can be used to maintain constant pressure within the cylinder and to thus apply a constant force to the bearing. The take-up frame assembly can also be used in combination with a controller and belt alignment devices which sense the relative position of the conveyor belt. When the conveyor belt falls out of alignment, the controller is capable of varying the pressure within the fluid cylinders in order to realign the belt.
