Abstract
This paper proposes the conception of full balance friction hoist shiplifts to supply the solution of the problems in layout of the main hoists, locking of the ship chamber under the thorough water leakage accident, and insufficiency of ship chamber pitch stability, existed in traditional full balance winch shiplifts for large tonnage design ships and high lift. The test study for measuring the friction coefficients under lubrication has been conducted and the pivotal issues such as compact layout of main hoists by employing friction hoists, fortification of the thorough water leakage accident, and pitch stability of ship chambers have been elucidated. The scheme comparison of 200m/3000t between full balance winch shiplifts and full balance friction hoist shiplifts has been conducted which shows that full balance friction hoist shiplifts supplies the solution for fortification of the thorough water leakage accident and enhancement of the pitch stability of the ship chambers of shiplifts for large tonnage ships and high lift.

Keywords
Shiplifts, friction hoist, compact layout, fortification, thorough water leakage accident, pitch stability.
