ABSTRACT:
A method for deploying a belt on a large conveyor belt system which extends down slope. A run of the belt is positioned at an upper position along the slope, and is engaged with a controllable brake which is configured to permit selective adjustment of the braking force which is exerted thereby on the belt. The belt is then lowered along the conveyor belt system using the weight of the run, and the rate at which the run of belt advances is controlled by selectively adjusting the braking force which is exerted by the controllable brake. The runs of belt may be lowered from adjacent high points in the conveyor belt system and spliced together where these meet in the valleys between the high points. The controllable brake assembly may be made up of a plate which extends across the belt and an inflatable bladder which is positioned on top of the plate and beneath its support, so that as fluid pressure is selectively added to the inflatable bladder, this biases the plate against the belt so as to control the braking force which is exerted by the plate against the belt.
