Abstract:
An elevator system includes a car or platform to transport passengers and/or goods as well as a counterweight, which are arranged as traversable or movable along a travel path, and which are coupled and/or with a drive by a suspension element interrelating their motion. The suspension element is guided and/or driven by a traction sheave and/or a drive shaft and/or a deflecting pulley. The suspension element is a sheathed and/or belt-type, with a first layer made of a first plasticizable and/or elastomeric material and a second layer with a connection plane formed between the first and second layers. At least one tension member—rope-type, tissue-type, or comprising a multitude of partial elements—is embedded in an area of the connection plane, a majority of a surface of said at least one tension member directly contacting said first layer. A manufacturing procedure for one of the suspension elements is provided.
Abstract:
A rope system (10, 20) comprising a splice structure (12, 22) with an intact portion (23) comprising at least 8 intact strands (32, 34), and a disassembled portion (26) comprising at least 4 loose strands (30), wherein the intact portion (23) is a braid of at least 4 S oriented (32) and at least 4 Z oriented intact strands (34), wherein at least one loose strand (30) of the disassembled portion (26) passes under and over intact strands (32, 34) of the intact portion (23), and at least one loose strand (30) passes under at least one X-tuck (38) of intact strands (32, 34). By this means the splice length can be minimized resp. slippage of the splice at high loads can be avoided.
Abstract:
A cord rubberized in situ (C). Internal layer of the cord (CT1) comprises N1 internal thread(s). External layer of the cord (CT3) comprises N3 external threads wound helically around the internal layer of the cord. Rubber composition (20) is positioned between the internal layer of the cord and the external layer of the cord, and comprises a compound of formula (I) or a salt of this compound: in which: each R1, R2 and R3 group represents, independently of one another, an alkylene, arylene, arylalkylene, alkylarylene or cycloalkylene group, each X1 and X2 group represents, independently of each other, —COOH, —CO—NH—OH, —SOOH, —PO(OR)(R′) or —PO(OR)(OR′) with R and R′ representing, independently of each other, hydrogen or an alkyl group, and X3 comprises at least one —COOH, —CO—NH—OH, —SOOH, —PO(OR)(R′) or —PO(OR)(OR′) group with R and R′ representing, independently of each other, hydrogen or an alkyl group.
