How to remove the support system and end cap

Abstract

To reduce a torque required to loosen a bolt as a fastener.SOLUTION: A support system (10A, 10B) includes: a temperature detection section (20) that detects a temperature of one or both of an end cap (3) and a fastener (B); and a control section (40) that suggests removing the fastener (B) if detected temperatures (T1, T2) detected by the temperature detection section (20) satisfy a predetermined work start temperature (Te) condition.SELECTED DRAWING: Figure 3
