A travelling cable end hitch and rail arrangement for an elevator system includes a rail assembly fixed to an elevator car of the elevator system, a movable device positioned at and movable along the rail assembly, and an end hitch portion of a travelling cable of the elevator system secured to the movable device and movable with the movable device along the rail assembly. A method of accessing a travelling cable end hitch of an elevator system includes accessing a travelling cable from inside of an elevator car, pulling the travelling cable upward from inside of the elevator car, moving an end hitch portion of the travelling cable along a rail assembly secured to a bottom of the elevator car via pulling the travelling cable upward, and inspecting the end hitch portion from inside the elevator car when the end hitch portion reaches a first end of the rail assembly.

The present disclosure refers to an elevator system particularly for high buildings, comprising: an elevator car comprising one or more electrical service appliances; a counterweight; a power source housed into the counterweight; a hoisting cable connected at a first end to the elevator car and at a second end to the counterweight and comprising carbon nanotube (CNT) yarns, wherein the CNT yarns mechanically support the elevator car and the counterweight and are electric conductor from the power source to the electrical service appliances.

An elevator belt monitoring apparatus includes a housing for receiving an elevator belt and a plurality of blade contacts which are operable to pierce the belt and engage the spaced parallel cords arranged within the belt. A plurality of bridge contacts are connected with adjacent pairs of elevator belt cords and signal contacts are connected with cords at the outer edges of the belts. The signal contacts are connected with a monitoring device which sends and receives signals to the contacts to provide an indication of the condition or deterioration of the belt.

An elevator cable management system is described to provide constraints on cable movements at a point between the top and bottom of an elevator track. The system may include a moving retainer bar with a cradle on top of an elevator car, and a fixed retainer bar that retains cables when the elevator car is above the fixed retainer bar.

The present disclosure is related to a travelling cable clamp assembly fixing an elevator travelling cable to a fixing base, such as to a first movable support structure in the hoistway for supporting said at least one elevator unit movable in the hoistway, including at least an elevator car.

The arrangement comprises at least one travelling cable, a guide rail extending from a pit floor at least to a middle of an elevator shaft, an intermediate fixing point positioned in connection with the guide rail, the at least one travelling cable being fixedly attached in said intermediate fixing point, a travelling cable keeper being movably supported on the guide rail so that the travelling cable keeper is movable upwards and downwards along the guide rail, the at least one travelling cable being movably supported in support points on the travelling cable keeper, a path of the at least one travelling cable through the support points in the travelling cable keeper being curved, the at least one travelling cable being movable through the support points.

An elevator system including: an elevator car configured to travel through an elevator shaft; a first guide beam extending vertically through the elevator shaft, the first guide beam comprising a first surface and a second surface opposite the first surface; a propulsion system configured to move the elevator car through the elevator shaft; a first on-board energy management system configured to power the propulsion system, the first on-board energy management system is attached to the propulsion system and configured to travel with the propulsion system.

A method for controlling an operation of an elevator system is discloses. The elevator system includes an elevator car moving within an elevator shaft and at least one elevator cable connected to the elevator car and the elevator shaft to carry electrical signals to the elevator car. The method determines a counter force on the elevator cable required to change a nominal shape of the elevator cable to an inverse shape of a current shape of the elevator cable caused by disturbance on the elevator system and applies the counter force to the elevator cable.

An exemplary device for protecting an elevator travelling cable connected to an elevator car comprises a deflector that is configured to be secured to one of an elevator car or the travelling cable. The deflector allows the travelling cable to extend below an associated elevator car a first distance from a bottom of the elevator car when the elevator car is at least a selected height above a bottom of a hoistway. The first distance is at least equal to a natural dynamic bending radius of the travelling cable. The deflector facilitates the travelling cable extending below the bottom of the elevator car a second distance that is less than the natural dynamic bending radius when the elevator car is below the selected height.
