## Narrative

A maintenance employee was installing a harmonic balancer on a crank shaft on a frac pump. He was pulling himself up using a strap when the strap sheared a bolt holding some of the components together.  This caused the metal lifting eye to fall and strike the employee's hand, resulting in an amputation of the right pinky finger.
