Kernrechtsfrage
Whether the claimant had a pension-entitling degree of invalidity.
Extrahierter Entscheid
No pension-entitling invalidity degree was established; the claimant remained fully work-capable in his former occupation with limited heavy work.
Extrahierte Begründung
The cantonal findings on work capacity were binding and not manifestly incorrect. The medical record did not justify further investigations, and alleged psychiatric complaints were not invalidating.
