An elevator system () includes an elevator car () that is configured to travel along a guide rail (), and a braking assembly () coupled to the elevator car (). The braking assembly () is configured to selectively operate in a disengagement mode that allows the elevator car () to travel along the guide rail (), and an engagement mode that inhibits the elevator car () from traveling along the guide rail (). The electronic braking assembly controller () is in signal communication with the braking assembly () and is configured to generate an electronic braking signal that activates the engagement mode of the braking assembly (). When the engagement mode is activated, the elevator car () decelerates without exceeding a predetermined g-force (g) threshold regardless as to whether a load applied to the elevator car () changes such that the elevator car () is stopped at a floor landing ().

Monitored braking blocks

An elevator system includes a hoistway and an elevator car suspended in the hoistway via a suspension member and drivable along the hoistway. The elevator car includes an elevator car panel and a battery pocket positioned in the elevator car panel. A battery is removably positioned in the battery pocket. The battery and the battery pocket are configured such that inspection, maintenance and/or repair of the battery is performed without entry into the hoistway of the elevator system. A method of servicing an elevator system includes driving an elevator car along a hoistway and stopping the elevator car near a selected elevator landing floor. A battery is at least partially removed from a battery pocket at the elevator car via a technician located at the selected elevator landing floor for inspection, maintenance, replacement and/or repair.

A counterweight assembly for an elevator system includes a counterweight and a guide shoe affixed to the counterweight, the guide shoe extending continuously and unbroken along a vertical length of the counterweight. A counterweight guide system for an elevator system includes a plurality of first counterweight guide brackets secured in a hoistway at a first side of a counterweight and interactive with a first guide shoe affixed to the counterweight. A plurality of second counterweight guide brackets are secured in the hoistway at a second side of the counterweight opposite the first side and interactive with a second guide shoe affixed to the counterweight. Two or more first counterweight guide brackets are engaged with the first guide shoe during travel of the counterweight along the hoistway.

An elevator system comprises a hoistway (), an elevator car () arranged to move vertically within the hoistway and a drive machine () arranged in the hoistway outside the travel path of the car () or vertical projection thereof. The car () is coupled to the machine () by a rope () which is guided by a pair of idler sheaves () so as to pass under the car (). The idler sheaves () have a diameter of less than 120 mm. The disclosed arrangement allows both overhead space and pit depth to be minimised.

An exemplary vibration isolation assembly for use with elevators includes a first rigid member having an outer wall at least partially surrounding a central opening. A second rigid member is at least partially received within the central opening of the first rigid member. A resilient layer between the first and second members substantially isolates the first member from vibrations of the second member.

An electric safety switch () resetting device () for the car safety device () of elevators includes a switch () shaped as a box attached to the lower skirt () of the car frame, near the car safety blocks (). A mobile upper tongue () is engaged with a car safety block triggering lever (), which tongue () can trigger the switch () under the action of said triggering lever () and reset it in the opposite direction when operated by the maintenance operator. A connecting rod arrangement () hinged to the tongue () can be remotely actuated by the operator using an actuator () while standing at the landing opening near the arrested elevator car, to drive said tongue () to a position that will reset the switch ().

Safety top balustrade for a car of a machine room-less elevator which moves in a hoistway, on a wall of which the controller of the elevator is secured, said balustrade comprising:&#x2014;a fixed structure () comprising a plurality of vertical uprights () fixed at intervals near edge of the car roof () and at least two horizontal tubular guard rails () fixed at different heights on the uprights, around the periphery of the car roof, except at the place which is in front of the controller () when the car is at the level of controller, in order to leave a passage () for direct access to the latter,&#x2014;a mobile structure () comprising at least two horizontal bars () which are telescopically mounted inside the tubular guard rails, so as to slide between an open position where the bars are inserted within the guard rails, to free said passage towards the controller, and a closed position where the bars are extended out of the guard rails, whereby said passage is obstructed.
