  • Patent number: 11713211
    Abstract: A belt of an elevator system includes one or more tension elements extending longitudinally along a length of the belt, and an elastomeric jacket at least partially enveloping the one or more tension elements. The jacket defines a traction side configured to be interactive with a traction sheave of the elevator system and a back side opposite the traction side. A protective tape is applied to the elastomeric jacket at the back side. A method of assembling an elevator system includes forming a belt, and installing the belt in a hoistway of the elevator system. One or more additional components of the elevator system are installed in the hoistway. A protective tape is removed from a jacket of the belt after installation of the one or more additional components is completed.

  • Patent number: 11686228
    Abstract: Systems and methods are provided for remotely monitoring liquid lubricant levels for pump equipment. A system includes a reservoir to store lubricant and a lubrication gland to expose a shaft seal of the pump equipment to the lubricant. A feed line and a return line circulate the lubricant between the reservoir and the lubrication gland. A level sensor is configured to measure a fluid level in the reservoir. The level sensor uses a communication interface to transmit fluid level data a monitoring device mounted to the pump equipment. The monitoring device is configured to compare the fluid level data against stored alert thresholds and send, to a provider network, an alert signal when the fluid level data is below an alert threshold. If the fluid level data is not below an alert threshold, the monitoring device stores the fluid level data for periodic reporting.
