Spring starter, as known as hand starter, spring motor, spring powered starting device, etc, is a kind of mechanical starter which transform manual cranking energy into disc spring potential energy. The potential energy can be released all in once so as to start engine. It is the best starting solution for the “black-start” or “dead-ship start”.
Advantages
Spring starter can complement the electric starter defect, which battery needs maintaining frequently. It can ensure that engine can be started when the battery lacks of power. Unlike air starter and hydraulic starter, spring starter itself is a complete system. It requires no maintenance and other auxiliaries.
Applications
