Self-Lubricating Braided Fiber Load Carrier with Embedded Optical Monitoring

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a durable load carrier, such as those used in elevator construction, made with two braided polymer fiber reinforcements embedded in a flexible matrix. It incorporates a lubricant in the form of a bleeding plastic to reduce friction and extend durability. The design may include a control device with an optical wave guide for monitoring or control purposes.

Use CasesContent extracted from patent full text and abstract with AI.

• Elevator hoisting systems and other vertical transportation in buildings

Patent Abstract

The carrier (1) has two braided reinforcements (2) embedded into a flexible matrix material (3) and supplied with lubricant that is formed as bleeding plastic. A lubricant supplying device is provided in the braided reinforcements, and supplies the lubricant to the braided reinforcements, where the lubricant supplying device is designed as a cartridge or a hose. The reinforcements are made of high-modular polymer fibers such as aramide fibers, thermotropic liquid crystalline polymer (TLCP) fibers, high modulus polyethylene (HMPE) fibers or polyphenylene-2, 6-benzobisoxazole (PBO) fibers. The carrier comprises a control device that is provided with an optical wave guide made of glass or plastic. An independent claim is also included for a method for production of a load carrier.
