Conveyor Belt Installation
Once the roll of belting has been transported to the point of installation, it should be mounted on a suitable shaft for unrolling and threading onto the conveyor. Conveyor belting is normally rolled at the factory with the carrying side out.
Consequently, in mounting the roll the belt must lead off the top of the roll if it is being pulled onto the troughing or carrying idlers, but it must lead off the bottom of the roll if it is being pulled onto the return idlers. When pulling the belt onto the conveyor or radial stacker, the roll will turn opposite the direction indicated by the arrows on the crate. The drawing bellows illustrates a suitable method of mounting as well as leading off the top of the roll for pulling onto the troughing idlers.
In some cases, such as in mines, where head room does not permit maneuvering a roll, the belt may have to be pulled off the roll and re-fed. Extreme care should be exercised to see that the loops have large bends to avoid kinking or placing undue strain on the belt, and no weight should ever be placed on the belt when it is in this position. (Figure 1) Another method of handling belting under such conditions is to lay the roll on a turntable with a vertical spindle.
Handling The Roll
Reels or rolls should never be dropped from a freight car, truck, or other means of conveyance since their weight will break the packaging and may damage the belt. Reels or rolls should always be rolled or provisions should be made for hoisting them. For hoisting, a bar is passed through the hole in the center of the roll. Chains or cables looped around the bar ends should be provided with a spreader above the roll to avoid damage to the belt edges.
