A belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt, a jacket material at least partially encapsulating the plurality of tension members, and a primary overlay layer applied to one or more of the plurality of tension members or at least a portion of the jacket material. An elevator system includes a hoistway, an elevator car movable therein, and a belt operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway. The belt includes a plurality of tension members arranged along a belt width and extending longitudinally along a belt length, a jacket material at least partially encapsulating the plurality of tension members, and a primary overlay layer applied to one or more of the plurality of tension members or at least a portion of the jacket material.

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.

The invention relates to a method for monitoring condition of a rope of a hoisting device, which rope comprises one or more load bearing members oriented to extend parallel with longitudinal direction of the rope throughout the length thereof. The method comprises measuring strains of one or more portions of a load bearing member of the rope; and comparing the measured strains of one or more portions of a load bearing member of the rope with at least one reference. The invention also relates to a hoisting device implementing the method.

A tension member for a lifting and/or hoisting system includes a core including a plurality of load carrying fibers arranged in a matrix material, and an outer layer secured to the core including a plurality of outer fibers arranged around a perimeter of the core. The outer layer includes one or more outer fibers arranged off-axis relative to the load carrying fibers of the core. A method of forming a tension member for an elevator system includes arranging a plurality of load carrying fibers along a length of the tension member, retaining the plurality of load carrying fibers in a matrix material to define a core, and enclosing the core in an outer layer including a plurality of outer fibers arranged around a perimeter of the core. The outer layer includes one or more outer fibers arranged off-axis relative to the load carrying fibers of the core.
