The system comprises a synchronization shaft rotatably supported on an elevator car frame, the synchronization shaft being operatively connected to at least one safety gear, a lever attached to the synchronization shaft, an electromagnet operatively connected to the lever, spring means operatively connected to the synchronization shaft, and resetting means operatively connected to the synchronization shaft. Deactivation of the electromagnet releases the lever allowing the spring means to rotate the synchronization shaft from a first position to a second position in which the safety gear is activated. Activation of the resetting means rotates the synchronization shaft from the second position to the first position in which the safety gear is deactivated and the spring means is brought back to the excited state at the same time.

A resetting device for resetting an actuator for actuating a safety gear of an elevator includes an actuation spring to be brought into a compressed state by a resetting force, an electric motor for providing the resetting force and a transmission for transmitting the resetting force of the electric motor to the actuation spring. The transmission provides a positive gear ratio.

A rope lifting tool for belt-shaped ropes comprises a first guide for guiding the rope lifting tool along a first guide rail; a second guide for guiding the rope lifting tool along a second guide rail; an upright plate, and an inclined plate at an acute angle relative to the upright plate. The upright plate and the inclined plate have a wedge shaped space between them. A plurality of wedge members are placed adjacent each other inside the wedge-shaped space. A rope gap for receiving an end of a belt-shaped rope is formed between each wedge member and the upright plate, which rope gap is narrowable by wedging of the wedge member in the wedge shaped space. A rope lifting arrangement includes the rope lifting tool.

A drive machine for an elevator includes a motor module including at least a motor, a drive shaft, and a first transmission wheel, which are provided with a common rotational axis and connected coaxially to each other. The drive machine further includes a traction module including at least a traction wheel engageable with elevator hoisting ropes, and a second transmission wheel, which are provided with a common rotational axis and connected coaxially to each other. The motor module and the traction module are positioned side by side with their rotational axes parallel, such that the traction wheel and the drive shaft are side by side, and the first and second transmission wheels are side by side. The drive machine further includes an endless drive member passing around the first and second transmission wheels. An elevator comprising said drive machine is also disclosed.

A method is provided for manufacturing an electrical contact arrangement on an end of a hoisting rope of a hoisting apparatus, which hoisting rope includes a non-conductive coating, and a plurality of adjacent conductive load bearing members for bearing the load exerted on the rope in a longitudinal direction thereof embedded in the coating and extending parallel to each other and to the longitudinal direction of the hoisting rope unbroken throughout the length of the rope, the coating forming the surface of the hoisting rope and extending between adjacent load bearing members thereby isolating them from each other, in which method a conductive plate element is placed beside the end of the hoisting rope; and the conductive plate element is attached immovably beside the end of the hoisting rope with at least one threaded screw member made of conductive material by screwing the threaded screw member into the hoisting rope such that it extends centrally between load bearing members next to each other, and such that the threads thereof are in contact with both of said load bearing members next to each other, the conductive plate element being thereby brought to be in conductive connection with both of said load bearing members next to each other via said at least one screw member.

Method and arrangement

A rope terminal assembly of an elevator fixing an elevator rope to a fixing base such as an elevator unit, the elevator being suitable for transporting passengers and/or goods, includes an elevator rope, whose width is larger than its thickness in a rope transverse direction, with at least one end having an end face, a rope end block attached to the rope end, one or more wedge elements, a wedge housing, where the terminal assembly includes a rope gap through which the elevator rope passes and the wedge element is arranged to wedge between the rope and the wedge housing thus locking the elevator rope in the gap, and the rope end block is attached on the end face side of the elevator rope with respect to the wedge element, and an elevator.
