Armar Working elevators offer a modified range of generators ranging from 1 kw to 160 kw. Generators over 15 kw are all in soundproofed boxes, making them very quiet. All generators have samples for 220v/16A and 3x380v 16/32/63A and the larger generators can also be directly connected.
To find out power requirements, consider that a drill machine takes about 0.5 kw, a concrete mixer about 2 kw, an average construction crane operator about 70 kw. Also, of course, you can always contact an employee of Arma Vinnulyftur and get assistance in estimating the power requirement/size of the generator. A generator must be approximately three times larger than the electric motor of an appliance being used.
Note that all generators need to be grounded by an earth electrode.
