Liht Hoist Starting


Recommended Posts

At sites, we use double cage external lift hoist, single and double speed, with countre weight and without CW.

The starting DOL current for sigle cabin hoit is 163 A ( three motors on a rack. each is 11 KW).

We use a generator 250 KVA ( 200 KW ).

The question is : How to minimize this starting current. so we can use a generator with less capacity.

Lift Hoist brand is GJJ - China.

Do a ciecuit Star - Delta with 2 sec switiching wll be enough?

or Do an inverter will be good regardless of the cost?
