Synchronization of Multipoint Hoists

Abstract

A contractor has conceived an electrohydraulic feedback system that will provide position synchronization of four aircraft cargo hoists. To demonstrate the feasibility of the concept and to verify the method of analysis, the contractor has designed, fabricated, and tested a model four-point synchronized hoist system. Test results show that the feedback system concept provides adequate synchronization control; i.e., the platform pitch and roll angles do not exceed plus or minus 5. The analysis derived to predict performance of the feedback system was shown to be valid.
