製作仕様改善と日常点検、整備の強化
・補強リブを大きくする。φ440→φ640
毎月一回、目視検査を行い摩耗量やクラック等をチェックする。
毎年、予備品と入替を行い、摩耗箇所の補修を行う。

修理
今回のように完全にランナーが折れた場合は、新たにランナーを付け直しする修理方法となります。費用としては新作する場合と変わらなくなります。さらにタイの場合は輸出入費用も発生するため、新作したほうがトータルでコストを抑えることができます。

ランナーシャフトは、補強用リブとの溶接部が摩耗したために強度が低下した。そのためランナーの根元にクラックが発生し、最終的に折損した。

MeasuresMaking design improvements and daily reinforcement of inspection and maintenance-To increase the reinforcement rib. 440 mm to diameter 640Monthly 1 times, performs a Visual inspection, checking for wear, cracks, etc.Each year, spare parts and replacement, repair of wear parts.RepairAs if the runner is broken completely new reseated the runner will be and how to fix that. As new as the cost remains unchanged. You can minimize costs in total is even if Thailand's import and export costs due to the new.Decreased strength to wear runner shaft is welded with reinforcing ribs. As a result and cause cracks at the base of the runner, was broken in the end.

Measures
production specification improvements and daily inspections, strengthening of development
to increase the-reinforcing ribs. φ440 → φ640
once a month, to check the amount of wear Carry out a visual inspection and cracks.
Every year, do the replacement and spare parts, carry out the repair of worn parts.

Repair
completely if the runner is broken as of this time, it will be the repair method to be newly re-attach a runner. The cost will not change the case of new work. Furthermore, since in the case of Thailand also be generated import and export costs, it can be better to new work will reduce the cost in total.

Runner shaft, the intensity was reduced in order to weld the reinforcing ribs is worn. Therefore cracks occur at the base of the runner was finally broken.
