The round slings are the only slings wherein the actual load bearing material is hidden from the sling user for visual inspection. The inspection criteria of round slings are only relied on appearance and condition of its outer cover. Even if round sling have overload indicator there is no predictable way to determine when the failure indicator will be triggered. Even a perfect looking round sling on outside could have worn bearing yarn at inside. Till present all round slings rely on outer cover without any rated capacity, of numerous qualities, specifications and material and with flimsy inspection systems which all have experienced do not work !!
