When coated elevator ropes are used electrostatic charge may build up in the ropes due to the insulating coating. These charges generate repelling or attracting forces between the parallel ropes, which hampers the correct miming of the ropes in the pulleys and in extreme cases may derail the coated elevator ropes. The wedge and socket clamps according the invention discriminate themselves from prior art wedge and socket clamps in that the piercing instruments are provided in the low tension zone of the clamp. These piercing instruments can take the form of pins, fins or other protrusions and establish an electrical connection between the wedge and the conductive tensile member. Such an elevator clamp allows to leak static electricy being build up or allows wear detection per elevator rope. ## Claims ### Claim 1 A clamp for holding an end of a coated elevator rope, the elevator rope comprising one or more tensile members surrounded by a coating, said clamp comprising a wedge and a socket body having an internal tapered hollow, said wedge being receivable in said internal tapered hollow of said socket body, said wedge having a clamping track and a holding track, wherein said wedge is provided with one or more piercing instruments on the holding track of said wedge, said piercing instruments for piercing the coating of said elevator rope, said piercing instruments being electrically conductive. ### Claim 2 (depends on 1) The clamp according to claim 1 wherein said wedge is provided with a contact member for electrically contacting said wedge with said socket body. ### Claim 3 (depends on 2) The clamp according to claim 2 wherein said contact member is an electrically conductive spring. ### Claim 4 (depends on 1) The clamp according to claim 1 wherein the wedge is provided with a key for insertion into said internal tapered hollow. ### Claim 5 A clamp for holding an end of a coated elevator rope, the elevator rope comprising one or more tensile members surrounded by a coating, said clamp comprising a wedge and a socket body having an internal tapered hollow, said wedge being receivable in said internal tapered hollow of said socket body, said internal tapered hollow having an aligned side and an inclined side, wherein said inclined side of said internal tapered hollow is provided with piercing instruments, said piercing instruments for piercing the coating of said elevator rope, said piercing instruments being electrically conductive. ### Claim 6 (depends on 1) The clamp according to claim 1 wherein said piercing instruments are pins, fins or protrusions that have a height that is larger than the thickness of the coating of the elevator rope. ### Claim 7 (depends on 1) The clamp according to claim 1 wherein the material of said piercing instruments is a metal or metal alloy that has an equal or lower electrochemical potential relative to the conductive tensile member. ### Claim 8 (depends on 1) The clamp according to claim 1 wherein said wedge and socket are shaped to receive a tension member with a round cross section. ### Claim 9 (depends on 1) The clamp according to claim 1 wherein said wedge and socket are shaped to receive a tension member with a rectangular cross section. ### Claim 10 (depends on 1) The clamp according to claim 1 wherein said wedge and socket are shaped to receive a tension member with a cross section comprising in-line round sections that are lengthwise connected to one another. ### Claim 11 (depends on 1) An elevator comprising a cabin supported by one or more elevator ropes, wherein said elevator ropes comprise one or more electrically conductive tensile members surrounded by an insulating coating wherein at least one end of said elevator ropes is held with a clamp according to claim 1. ### Claim 12 (depends on 11) The elevator according to claim 11 wherein at least one end of each of said elevator ropes are held with the clamp. ### Claim 13 (depends on 11) The elevator according to claim 11 wherein all electrically conductive tensile members are electrically connected to one another through said clamps. ### Claim 14 (depends on 13) The elevator according to claim 13 wherein all electrically conductive tensile members connect to ground at the same end side of said elevator ropes.
