Load carrier e.g. returnable load carrier, for use in construction of e.g. lifts, has two braided reinforcements embedded into flexible matrix material and supplied with lubricant that is formed as bleeding plastic

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
• Industrial lifting equipment requiring strong and flexible load carriers
• Construction of lifts in mines or high-rise structures
• Load-carrying ropes or cables in cranes
• Automated storage and retrieval systems

BenefitsContent extracted from patent full text and abstract with AI.

• Enhanced durability and lifespan due to low-friction, self-lubricating fibers
• Improved safety and reliability for elevator and lifting applications
• Flexibility and strength from use of high-performance polymer fibers
• Integrated control or sensing capability via optical wave guides
• Reduced maintenance needs owing to embedded lubrication

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.
