It replaces electrical starter motors and allow engines to be started easily and safely without battery or alternator. It is also popular for standby starting system.

Disc spring benefits for starting are:-

  • High output torque
  • Robust in construction.

Spring Starters are available to suit various makes of engine such as Caterpillar, Cummins, Deutz, Volvo and many other engines.
