The invention relates to a rope terminal assembly of an elevator fixing an elevator rope to a fixing base such as an elevator unit, said elevator being suitable for transporting passengers and/or goods, said assembly comprising an elevator rope, whose width is larger than its thickness in a rope transverse direction, with at least one end comprising a first member with a first end face and a second member with a second end face, a wedge element, a wedge housing, the rope terminal assembly comprising a rope gap through which said elevator rope passes and said wedge element is arranged to wedge between the first member with the first end face and the second member with the second end face of the elevator rope thus locking said elevator rope in the gap, and an elevator.

A system for spreading tension at a rope connection point on a structure is provided. The system comprises a connection mechanism configured to receive a rope. The system also comprises a fastening mechanism configured to couple the connection mechanism to the structure at the rope connection point. The rope is configured to enter the connection mechanism at an inlet point and exit the connection mechanism at an outlet point, such that a tension applied to the rope is spread between the inlet point and the outlet point.

A method for connecting a wire cable to a cable shoe for a belt buckle mounting comprises the steps of: pre-bending a retaining portion of the cable shoe to form an eye; inserting the wire cable into the eye; extruding the retaining portion so that the outer periphery thereof is reduced. The extrusion of the retaining portion is carried out as impact extrusion, wherein a form closure is produced between the retaining portion and the wire cable. The impact extrusion is carried out by a tool including at least one edge-free first seat for the eye. An apparatus for connecting a wire cable to a cable shoe for a belt buckle mounting comprises a first tool half including a first seat for a retaining portion of the cable shoe pre-bent into an eye and an opposed second tool half including a second seat for the retaining portion. The two tool halves can be forced against each other with high pressure so that the material of the retaining portion starts to flow. At least the first seat is free from edges.

A dead end structure for supporting a cable having a core portion includes a first support portion extending between a first end and a second end. A second support portion is attached to the first end of the first support portion. A third support portion is attached to the second end of the first support portion. A first helical winding and a second helical winding engage one another such that a first axial opening and a second axial opening are axially aligned to define an axial support opening into which the core portion of the cable is received. The second support portion and the third support portion apply a radial compressive force to the core portion. A sleeve defines an axial opening. The second support portion and the third support portion are received within the axial opening of the sleeve.

Embodiments of a rope tension device for cinching a load with a rope are disclosed. The rope tension device includes a frame and brake member. The frame includes a first rail and a second rail with a bracing structure extending between the first rail and the second rail such that the bracing structure defines an arcuate surface. The brake member is pivotably coupled to the frame. Further, the brake member defines a brake surface such that the brake surface is biased with a spring member toward the arcuate surface, the brake surface defining an axially extending concave feature that faces the arcuate surface of the bracing structure. With this arrangement, a gap defined between the arcuate surface and the axially extending concave feature varies in height along an axial width defined between the first and second rails so as to receive the rope within the gap for cinching the load.

An attachment system for securing an object, such as a seismic node or other external device, to a rope or cable includes a latch block and a latch member movably connected to the latch block for selective engagement with a coupling feature on the rope or cable. The latch block may be attached to or integrated with the object and can include opposing side members defining a channel extending through the latch block, the channel sized for selective receipt of the rope or cable therein. The latch member may selectively engage the coupling feature as the rope or cable is received in sliding engagement within the channel.

A helical jumper connector includes a helical support member configured to support a wire. The helical support member includes a first leg having a first helical winding and a second leg having a second helical winding that defines a second axial opening. The first axial opening and the second axial opening are coaxial with the wire when the first helical winding and the second helical winding are wrapped around the wire and cooperatively engage with one another to support the wire. A jumper casting is configured to receive the helical support member. The helical support member and the jumper casting are electrically conductive such that the helical jumper connector forms an electrically conductive pathway to carry electrical current from the wire. A method of making a helical jumper connector assembly includes applying a compression force to a helical jumper connector comprising a helical support member received in a jumper casting.
