Caught in, under or between a moving and a stationary object
Hyd. hoses on conv were too short; came off. Safety valve was activated, stopping conv from moving. Cat skid steer was used to hold conv to reconnect hoses. An oil leak caused conv to start settling. EE's arm was positioned in conv in order to reconnect the hoses; not realizing conv was slowly settling. The conv was on his arm when he realized what was happening, pinning it.
