2.3.2 Crossovers for aisles and passageways

Where access to either side of the conveyor is required. crossovers or underpasses shall be provided at appropriate intervals

including at the head and tail end, at the drive and other transfer points along the conveyor.

Where a conveyor crosses a walkway, aisle or passageway and the lowest part of the conveyor or material or attachment is less than 2. I m above the iloor or walkway surface, a crossover or underpass as appropriate shall be provided.

NOTE: For underground mining applications, the underpass may be a crawlway.

2.3.3 Working clearance

Where access is required along an operating conveyor, a minimum working clearance of 6(N) mm coupled with a minimum headroom of

2.1 m shall he provided down one side of the conveyor. The non-walk side of the conveyor should have sufficient clearance to allow any spillage of material to fall clear of the conveyor. Adequate clearance shall he provided between the material being conveyed

and the roof.

The provision for a minimum headroom of 2.1 m need not apply to underground mines.

Adequate clearance shall be provided to prevent inadvertent contact between the conveyed material and any part of the conveyor

system, including installed equipment or structures. Where it is possible to manually overload a conveyor to a point where adequate load clearance is not maintained, a load gauge should be installed at the loading points.
