1.1. GENERAL DESCRIPTION
Hi Roller® Conveyors are totally enclosed and self-cleaning belt conveyors. The
conveyors are designed to convey granular, dry (non-sticking) bulk materials
which are not excessively abrasive or corrosive; i.e. grains, oilseeds, absorbent
clays, borax, fertilizers, etc.; while containing any fugitive dust and spillage from
the conveyor. The conveyor is designed to be totally enclosed during normal
operations with all covers, guards, inspection doors, etc. installed at all times of
normal operations. Operating conditions are many above ground, storage
reclaim tunnels, receiving pits, and above water levels; inside and outside of
buildings, open & enclosed structures, and outdoors in most climates. There will
a limited number of exposed people and operators as the conveyors will be
typically installed in an industrial facility.
Conveyors are designed and manufactured to be a complete conveyor when
properly installed by the customer or his representative. Complete Approval
Drawings, Installation Drawings and Manuals are provided with each conveyor.
The customer and his representatives must follow these documents to properly
install each conveyor. The specifications provided with each conveyor must be
followed.
When operating or maintaining the conveyor, never:
• change the size of the electric motor or pulleys to change the belt speed with-
out written authorization from Hi-Roller.
• overfeed or overload the conveyor.
• operate the conveyor empty for extended periods of time.
• stand or walk on top of conveyor.
• load off-center on the belt, idlers, and shafting.
• use the conveyor to support other equipment.
• weld anything to the equipment.
• convey material other than dry granular material.
