When you need to start a diesel engine in extreme damp, cold weather and harsh environment, mechanical spring starter is a cost-effective manually emergency starting for various diesel engines freely used in the offshore platform, high salinity environments.

The Advantage of Mechanical Spring Starter
Mechanical spring starter is an emergency starter. It adopts a purely mechanical structure. Apart from manpower, it does not need to use other energy sources for working.
1.The hand crank inertia starter with the disc spring as the energy storage medium, which only uses the human power to compress the spring, and then instantaneously releases the torque and the rotational speed to the diesel flywheel to start the engine without energy consumption and pollution.
2. Installed on a diesel engine in a standard method without the need for batteries, compressed air tanks, hydraulic drives, or control valves, cables, etc.
3. With the unique and simple structure design, there’s no spark or radiation during use. The sturdy and reliable structure, which makes the mechanical starter, can be applied to spark sensitivity or the occasions of challenging to implement equipment maintenance.
4. Operate Safely: A mechanical starting device which is operated by humanly possible indirect hand cranking, and the motor can be unwound if not required.
5.Fast: Complete energy storage and release process by convenient human operation
The Application of Mechanical Spring Starter

1.General industrial: as the spare and replacement of other starting motors, It is used in marine diesel engine generator sets, mining machinery, engineering plant and agricultural irrigation, and drainage machinery.
2.Special environment: coal mines, oil fields and chemical plants.
3.Emergency occasions: fire pumps and lifeboats, military.
