Abstract
Patient lift systems having a telescoping lifting apparatus include a telescopically displaceable lifting beam and a fixed lifting beam. The telescopically displaceable lifting beam may be operable to extend out from the fixed lifting beam to a protruded position. A casing may be brought to surround both the telescopically displaceable lifting beam and the fixed lifting beam and extend a certain distance over both the telescopically displaceable lifting beam and the fixed lifting beam when the telescopically displaceable lifting beam is in the protruded position. A pressure spring may be situated within the casing between a top end of the casing, which may surround the telescopically displaceable lifting beam, and a spring support, which may attach to the fixed lifting beam.
