ABSTRACT:
A hydraulic positioning system for precisely and rapidly positioning objects of the type likely to impose impact loadings on the system. The system is particularly adaptable for use in sawmill setworks for precisely positioning logs preparatory to sawing thereof. High impact loads are compensated for by special rapid-acting shock-absorbing hydraulic relief circuitry responsive to differences between impact overpressure and system pressure.
