Spring Starter for diesel engine

Spring Starter Motor is a manual emergency hand crank starter for starting a diesel engine without any other power source. This device is reliable, used repeatedly and has a long operating life. So you can see, mechanical spring starter is the ideal solution for engine start without external power. Our HS-1 mechanical spring starter is a mechanical energy storage starter which is designed for a quick starting diesel engine. It has many advantages, such as good operation, reliability and conveniently installation. As optional starting, your engine can additionally install spring starter besides the electric motor.

What is the mechanical starter ?

A mechanical starter stores the manpower energy by compressing the disc springs and releases the energy by pulling the trip lever. And then the drive pinion will drive the flywheel to rotate. It is the ideal solution for a black start, mostly used in military, emergency rescue, firefighting, marine and some other conditions where require high reliability. It is also called mechanical spring starter, spring startup, hand starter, hand-operated spring starter.

What is the advantages of mechanical spring starter ?

Compared to an electric starter, the mechanical spring starter is maintenance-free. And compared to other means of starting, spring starter requires no external system such as battery, cable, air compressor, fuel tank and so on. Spring starter is waterproof, anti-corrosion, and produces no sparks. With natural anti-explosion structure, you can use it anywhere dangerous.

What are the features of mechanical starter ?

• Start-up guarantee: The manual starting is an absolutely reliable starting device that is not affected by harsh environments.
• Reliable design: The spring starter has a long history, a good record of user experience proven widely and praised worldwide with mature technology, premium material and strict control.
• Compact structure: The spring starter motor with a net weight is only half of the motor starter, which can help save space and weight for improving efficiency and make the operation easier.
• Safety: Safety is the core advantage of mechanical spring motor and the crank will not fly off or kickback during operation. And you can loosen the spring as needed.
• Easy to operate: Compare to the electric starter, the mechanical starter can be directly screwed to the diesel engine. Pull the stroke handle to release disc spring potential energy for driving the flywheel and the purpose of starting has been achieved.

What are the applications of mechanical starter ?

1. The occasions with high explosion-proof requirements : mining, petroleum processing and refining and so on.
2. The occasions of mechanical failure easily : shock, high temperature, dusty, High salinity, etc.
3. Emergency situations : rescue boat, military, emergency/standby electric generator sets.

Our HS-1 hand crank starter with spring inside can be widely used in lifeboat engine, marine emergency diesel generator, emergency diesel fire-fighting pump etc. It is the optimized engine starting as main or auxiliary starting. As we all know, the mechanical spring starter motor can meet the “black start” requirements of the power unit of the ship, if there is an event of electricity loss during the ocean sailing. In the ship regulations, it is required by the SOLAS when the ship is sailing. All ships need to be satisfied that when the whole ship loses power, there should be an emergency unit used to generate electricity for the ship. The mechanical spring starter is designed to achieve the emergency start requirements.
