Plastmass Group begins manufacturing pulley wheels made of INKUPOM C material (based on polyacetal)

The surfaces of our INKUPOM C pulley wheels have a low coefficient of friction and a lower abrasion effect on the rope, which extends the lifespan of the rope pull mechanisms. Our pulley wheels are low-vibration and can reduce the noise level during operation. The smooth operation of cranes and lifts creates more comfortable working conditions for the employees involved.

In contrast to cast iron pulleys, the use of special mechanisms for the installation of INKUPOM C pulley wheels becomes obsolete. The simplification of the train mechanisms ensures reduced installation and maintenance costs.

Advantages of INKUPOM C pulley wheels over cast iron pulleys:

  • Easy to install due to its light weight

  • Extension of the lifespan of the rope by 2 to 3 times due to less friction

  • Reduced operating and installation costs

  • Increased smoothness and more reliable operation

  • Reduction of the operating volume by three times

  • Operating temperatures from -60 to +100 °C



The Cheboksary ELBrus elevator plant particularly praises the quality of our new material.

Our INKUPOM C pulley wheels are processed precisely and then checked by the quality inspection according to customer specifications.
