The Engine Cranker for Automotive/Industrial Diesel/Petrol Engine is basically an industrial grade hi current dc, power supply. Nana Industries manufactures Engine Cranker for Automotive/Industrial Diesel/Petrol Engine. Nana Industries supplies different types of battery chargers in wide range of models. This Engine Cranker is robust in construction. The device is easy to operate. The Engine Cranker is designed for starting [cranking] any automotive or industrial Diesel / petrol engine. There are three different models according to the starter motor operating voltage. There are two main applications of Engine Cranker. First, it is very useful where 3 or 4 diesel Gen-sets are installed in one shed. By using this machine there is no need to keep separate batteries for starting the individual Gen-set. Only one DG set is to be started on the battery and with the power output of that DG set, cranker will start all remaining engines without the help of batteries. Thus recurring expenses of the batteries can be saved as well battery maintenance cost will be avoided. Plus there is no need of battery charger or engine alternator also. Secondly using Cranker is also beneficial for big Automotive Service stations or Huge Automotive Workshops, where number of Engines are Overhauled and tested. To start there Engines using these Batteries is a troublesome job, as the Batteries get discharged during repetitive Cranking. But the Cranker won`t, as it operates on mains it would crank the engine without any hassle.
