The spring motor is a kind of emergency start suitable for all kinds of diesel engines. It adopts a purely mechanical structure. In addition to manpower, it does not need to rely on other energy sources to complete the work process. The difference between it and electric motors, air motors, hydraulic motors, and other starting methods is that it does not need to be equipped with a variety of other auxiliary equipment.
So some people must ask, why is it necessary to use a spring starter to realize the manual start of the diesel engine in today’s advanced technology？ Because spring starters are generally used as backup starting devices. To make a less appropriate analogy, just like the current car keyless start, the popularization of the keyless entry system is convenient and intelligent, but there is still a mechanical key as an emergency backup switch. Provide a backup and reliable solution when the keyless start cannot work normally.
Features of Spring Starter
Of course, the spring starter must have its advantages, which has led people to continue to use and optimize this technology. The advantages of several spring starters are listed below.
- The spring starter can meet the cold start requirements of diesel engines, and can excellently complete the start task in the full load state.
- Starter installation complies with SAE standard
- The direction of the rotating shaft head can be adjusted to the best manpower rotating angle
- It can adapt to the needs of different diesel engines, and the superb material processing technology can ensure its long service life and can be adapted to different working environments. The severe cold area requires an auxiliary engine starting device.
The Spring Starter can be Installed in a Huge Diesel Engine
Spring starters are generally small in size, so the energy that can survive is also limited, and they are generally used for diesel engine components from 2L to 16L. However, no matter how large a diesel engine is, it is difficult to achieve a manual start through a spring starter. At present, diesel engines that need to meet the “black start” requirements are often large diesel engines with a displacement of more than 20L. Therefore, how to start a large diesel engine through a spring starter has become an important research topic. After long-term research and continuous testing, cqstart has developed a new 0 Group System Cqstart Hand Crank Spring Starter. This spring starter supports diesel engines up to 50L.
Working principle of hydraulic starter
Cqstart 0 Group System is consists of several spring starters in parallel through a special way, those spring starters can be any 2 or more types from our products, which can increase the ability to start the engine. It can be used on those engines whose displacement is up to 50L.
The combination of multiple starters leads to a wider range of starting capabilities. For large engine units, the cost of spring starters is much lower than hydraulic starters and air starters.

Advantages of Cqstart Spring Starter
Applicability (Adapt to harsh working conditions, including sparks, chemical and humid conditions.)
Safety (it is a mechanical starter that can be directly operated by humans. It can be used as a starting device under special conditions such as inflammable and explosive)
The structure is simple and complete (independent hand-operated working system, no electricity, gas, or other energy systems are required.)
Quick response (simple operation and quick release of energy.)
Maintenance-free (high and low-temperature resistance, corrosion resistance, no maintenance cost.)
Reliability (reasonable design, mature technology, high-quality materials, strict control.)
