It weighs less than conventional steel ropes, takes less space, does not require any oil or lubricant, and runs quieter. STM also saves shaft space because of the smaller motor and traction sheave that is 72% smaller than traditional systems. It is also enviromental friendly, durable, and easy to be installed.

For the safety device, Slack STM Detection Contacts already implemented at the both end of the belt.
