Ultra-modern Machines Developed in DPRK

 

Pyongyang, March 14 (KCNA) -- Various types of ultra-modern machines were developed in the machine industrial sector of the DPRK.

Among them are a speed reducer of large winch and a self-propelled motor winch.

They have been introduced into collieries, mines, machine-building factories and other units, playing a big role in promoting the economic construction.

The new type of speed reducer, which effectively ensures the smoothness of gear drive, is lower in production cost than previous ones and less in vibration and noise. A special brake principle was applied to this machine.

The self-propelled motor winch has no vibration in axial rotation, and it is safe from overload.

These machines with world competitive edge are of weighty significance in developing the technology of manufacturing power transmission devices.
