Elevator power management system and method
Disclosed is an elevator system for a multi-level architectural structure, the elevator system having an elevator controller for an elevator in a hoistway, wherein the elevator controller effects a first determination of whether passengers or goods are in the elevator and effects a power mode for the elevator based on the first determination.
Elevator system with thermal sensors
Disclosed is an elevator system having a first sensor in communication with an elevator in a multi-level hoistway, wherein during an emergency the elevator instructs the first sensor to sense conditions and transmit sensor data representing the sensed conditions, and the transmitted sensor data is processed to obtain an image representing an intensity of hazard conditions on at least a subset of levels serviced by the multilevel hoistway.
DOUBLE IMPACT AREA BUFFER FOR IMPROVED PLANK
A buffer device (121) for an elevator system (100), the buffer device (121) including a first contact structure (501) and a second contact structure (503). The first contact structure (501) includes a first contact surface (505), and the second contact structure (503) includes a second contact surface (507). The first contact surface (505) and the second contact surface (507) are arranged for contacting respective vertically offset surfaces of an elevator car (101) or counterweight (109).
Elevator system, with two emergency safety brake devices and a shock-proof system
An elevator system consisting in a platform steel floor fixed to four bogeys guiding the descent or ascension of the platform onto the two steel H beam or steel linear motion track profiles. The elevator is operated by a remote or pad control transmitting signals with a wire or with a wireless frequency signals to a motorised mechanical engine or electric winch at the ground level of structure, if not being manually operated and controlled. The motorised mechanical engine or electric winch unrolls one or a set of normal operation cables to allow the descent of the elevator platform and the sliding o f t he bogeys along the lateral guiding tracks. The motorised mechanical engine or electric winch rolls the set of normal operation cables to allow the ascension of the elevator platform and the sliding of the bogeys along the lateral guiding tracks. The set of operating cables drives a fixed pulley on a driving steel shaft at the top of the structure or elsewhere on the elevator system. On the driving steel shaft is also there one or many steel drums or pulleys to allow unrolling and rolling of a second independent steel cable standing for a first emergency safety brake device activated by one or many inertia brakes which stops rotation on steel shaft at excessive speed rotation of steel shaft if a fracture or breaking happens on the set of operating cables and engage the free falling of the elevator platform. The set of safety cables is attached to steel hooks fixed to the shock-proof steel plate attached underneath the elevator platform by compression springs and guided by steel rods inserting steel bushings. The shock-proof safety steel plate is retained by two fixed steel cables attached to elevator platform and to a steel hook half ring or U-Bolt mounted on the shock-proof safety steel plate.
The second emergency safety brake device is engaged when the two spur gears collides together after the compression of the springs or of any other kind of shock absorber when the set of safety cables ask to stop the free felling of the shock-proof steel plate and because the two opposite spur gears are taking two different directions onto the steel gear track or gear rack with teeth and also having then two different rotation direction; one spur gear is going down and the other spur gear is stopping its rotation. When the emergency break is applied for the elevator to stop its free falling, the safety trap on elevator floor can be lifted manually and be blocked by engaging the retainer steel arm in the corner steel angle and sided steel plate to allow the person to evacuate by the ladder bars fixed on the structure and the ladder bar underneath safety trap.
Method for constructing an elevator system having increasing usable lifting height
A method for constructing at least two elevators in a building under construction adapts the usable lifting heights of the elevators to an increasing height of the building, wherein each of the elevators is arranged in an elevator shaft of the building associated with the elevator and includes a drive platform having an elevator drive machine that supports and drives an elevator car and a counterweight by a traction sheave and at least one flexible suspension device. In order to adapt the usable lifting heights, lifting operations are performed in which in alternation one of the drive platforms is raised to a higher level in the associated elevator shaft and is locked there. A single lifting platform is temporarily fastened above the particular drive platform to be lifted to apply a lifting force required to raise the drive platform, which force is transferred to supporting elements of the elevator shaft.
EMERGENCY TERMINAL STOPPING SYSTEMS
An emergency terminal stopping system for an elevator system, the emergency terminal stopping system including: a sensor configured to determine data related to the motion of an elevator car moving within an elevator hoistway; at least one elevator brake configured to halt the motion of the elevator car; at least one elevator safety gear device provided on the elevator car; and at least one buffer provided at a lower portion of the hoistway.
Elevator car toe guard system
Elevator toe guard assemblies are provided. The elevator toe guard assemblies include an elevator car frame, a buffer located within an elevator shaft, and a toe guard mounted to the elevator car frame. The toe guard has a first state being a fully extended state, a second state wherein the toe guard does not contact a pit floor during operation of an elevator car, and a third state wherein at least a portion of the toe guard is moved relative to the elevator car frame during an impact between the buffer and the pit floor.
SAFETY ARRANGEMENT, ELEVATOR SYSTEM, AND METHOD FOR PREVENTING DERAILMENT OF AN ELEVATOR CAR AT A TURNING STATION OF AN ELEVATOR SYSTEM
A safety arrangement is suitable for a turning station of an elevator system. The safety arrangement includes at least one first blocking position for preventing, by a first mechanical device, an elevator car from entering the turning station, wherein the first mechanical device is arranged to change its position in response to operation of the turning station, and at least one second blocking position for preventing, by a second mechanical device, an elevator car from exiting the turning station.
Elevator buffer system
An elevator buffer system includes a buffer (44), a frame (30) spaced above the buffer, a platform (48) spaced above the frame, and a pre-compressed pad device (52) disposed between the frame and the platform and engaged to one of the frame and the platform. The system is constructed to move between a non-strike position, where the pre-compressed pad device is spaced from the other of the frame and the platform; a mid-strike position, where the pre-compressed pad device is in contact with the other of the frame and the platform; and a full-strike position, where the pre-compressed pad device is further compressed against the other of the frame and the platform.
