The electric-start-winch ESW-2B is the first mobile, high efficiency electric winch.
It´s the first winch which only needs a connection of 12 – 20 kW
giving a mechanical power output of 200 kW during launching ( 20 launches / h )!
It´s not an exotic invention, but a consequent development using standard components.
- is free of exhaust fumes
- has fewer mechanical components
- is nearly maintenance-free
- is always ready to start
- is very easy to operate
We use maintenance-free batteries as a " buffer " are permanently charged from the mains.
These batteries, may be omitted if there is a connection of
3 x 400 VAC / > 200 kW at the winch point.
