1 Application

DXZ-() / () series multi angle stroke limiter is a device imported a new safety protection technology from a French company PORTAN.It is suitable for AC 50 HZ,voltage 250 V and below, DC 30 V and below of the control circuit. On the bilateral control,optional position,corner traveling control and imitate sensor controller of 3 space coordinates, it has great advantages.It is widely apply to the control circuit of tower crane hoisting, port hoisting,various winch and other construction machinery or similiar mechanical.

This product with the characteristics of multiple function,small volume,large transmission ratio,high precision, easily and conveniently installation and regulation, and versatility and so on, acquired more and more widely application.
