Troubleshooting Challenge: Drill Rig’s Top Drive Drops Uncontrollably…  

A 65-ft.-high drill rig, mounted on a freshwater barge, was allowing its top drive head to drop uncontrollably. The circuit controlling this function shows (see illustration) both a brake (counterbalance) valve and a hydraulically controlled mechanical brake on the hoist function. The systems’ power...
