About HEXASTART
Hengxiang Jiechu Technology (Chongqing) Co., Ltd. is a technology company specializing in the R&D, sales, and technical services for engine starting systems in emergency and mission-critical environments. Drawing on Chongqing’s industrial cluster, we focus on power equipment, supplying high-quality products and tailored solutions to customers worldwide. Our core product lineup includes mechanical spring starters, high-torque electric starters, and air (pneumatic) starters, together with engine-related parts and accessories.
We partner with equipment integrators and operators in the marine, oil & gas, mining, data center, and firefighting industries, offering custom engineering, strict quality control, and rapid delivery.
When standard won’t start it,
WE WILL.
Situations we work on
A standard electric starter suits most engines. These are the situations where we are brought in.

Situation |
Where a standard starter falls short |
What we do |
|---|---|---|
|
It relies on batteries and electrical power, which can run down during long standby or be lost in a blackout. |
Spring starters are hand-wound to store energy mechanically. Air starters run on compressed air. Neither depends on batteries. |
|
|
A standard starter’s electrical components can produce sparks where flammable gas or dust is present. |
Spring and air starters produce no electrical sparks during starting. |
|
|
One standard starter may not deliver enough torque for large engines, which often use a dual-starter setup. |
On large engines, a single high-torque electric starter can replace a dual-starter setup. Spring starters cover engines up to 50 L and air starters up to 250 L. |
|
|
Older engines and non-standard flywheel housings cannot always take a standard starter. |
We develop custom designs for non-standard housings. A spring starter with a standard SAE flange can replace an electric starter without modifying the flywheel housing. |
How we work

Quality control & testing
Starting equipment has to work when it is needed, so quality checks are built into each stage.
Key components are checked before use.
Critical dimensions and assembly steps are verified.
Every unit is tested in-house before shipment, with dimensional checks and bench testing.
Technical documents are available on request.
