Travelling cable clamp assembly, an elevator arrangement, and a method

An elevator arrangement comprising:

• at least one elevator car movable in a hoistway;
• a first movable support structure configured to support the at least one elevator car movable in the hoistway;
• and
• a travelling cable clamp assembly configured to connect an elevator travelling cable to the first movable support structure in the hoistway, the travelling cable clamp assembly including,
• a travelling cable including an insulating jacket having a first planar surface and a second planar surface, conductors configured to transmit electrical energy and data to the elevator car, and one or more load-bearing elements configured to connect a first end of the travelling cable to the elevator car and a second end of the travelling cable to the first movable support structure, and
• a travelling cable clamp including a first plate element, a second plate element, and at least two spacers between the first plate element and the second plate element, the first plate element configured to contact the first planar surface of the insulating jacket, the second plate element configured to contact the second planar surface of the insulating jacket, the at least two spacers each being an elongated planar element having a length extending in a first direction of the one or more load-bearing elements and having a thickness in a second direction perpendicular to the first planar surface and the second planar surface that is greater than a diameter of the one or more load-bearing elements and less than a thickness in the second direction of the insulating jacket such that the first plate element and the second plate element are separated by a gap in the second direction through which the travelling cable is configured to lock between the first plate element and the second plate element, when the first plate element and the second plate element are pressed against the one or more load-bearing elements inside the insulating jacket without cutting open the insulation jacket.

A method of constructing an elevator configured to perform a jump-lift during construction thereof, the elevator including an elevator car having a travelling cable connected thereto, the travelling cable including an insulating jacket having a first planar surface and a second planar surface, conductors configured to transmit electrical energy and data to the elevator car, and one or more load-bearing elements configured to connect a first end of the travelling cable to the elevator car and a second end of the travelling cable to the a first movable support structure, the method comprising:

• using the elevator car to transport passengers and/or goods in a completed portion of a hoistway;
• lifting the first movable support structure higher in the hoistway, the first movable support structure configured to support the elevator car;
• releasing a travelling cable clamp to extend the traveling cable connected between the elevator car and the first movable support structure, the travelling cable clamp including a first plate element, and second plate element, and at least two spacers between the first plate element and the second plate element with the travelling cable therebetween, the first plate element configured to contact the first planar surface of the insulating jacket, the second plate element configured to contact the second planar surface of the insulating jacket, the at least two spacers each being an elongated planar element having a length extending in a first direction of the one or more load-bearing elements and having a thickness in a second direction perpendicular to the first planar surface and the second planar surface that is greater than a diameter of the one or more load-bearing elements and less than a thickness in the second direction of the insulating jacket such that the first plate element and the second plate element are separated by a gap in the second direction through which the travelling cable is configured to lock between the first plate element and the second plate element, when the first plate element and the second plate element are pressed against the one or more load-bearing elements inside the insulating jacket without cutting open the insulation jacket;
• and
• reenabling the elevator car again for transporting passengers and/or goods.

A cable clamp, comprising:

• a first plate element configured to contact a first planar surface of an insulating jacket of a cable;
• a second plate element configured to contact a second planar surface of the insulating jacket;
• and
• at least two spacers between the first plate element and the second plate element with the cable therebetween, the at least two spacers each being an elongated planar element having a length extending in a first direction of one or more load-bearing elements of the cable and having a thickness in a second direction perpendicular to the first planar surface and the second planar surface that is greater than a diameter of the one or more load-bearing elements and less than a thickness in the second direction of the insulating jacket such that the at least two spacers are configured to maintain a gap in the second direction between the first plate element and the second plate element such that the cable is configured to extend within the gap and to lock between the first plate element and the second plate element, when the first plate element and the second plate element are pressed against one or more load-bearing elements inside the insulating jacket.
