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.

An elevator car arrangement includes an elevator car body including a roof, a bottom and side walls, and an elevator car sling for being guided along vertically extending guide rails. The elevator car sling includes at least a first vertical side support, a second vertical side support and an upper horizontal support, which supports are connected to each other to form the sling. The elevator car body is connected to the elevator car sling such that the elevator car body is supported in the elevator car sling. The elevator car arrangement further includes a connection element for connecting the elevator car body to the elevator car sling such that the connection element is arranged between the roof of the elevator car body and the vertical side support of the elevator car sling, the connection element including a damper for damping vibrations caused by guide rails. A connection element for connecting an elevator car body to an elevator car sling is provided to form the elevator car arrangement.

An elevator system and a support column assembly. The elevator system includes a support column, with the bottom end thereof connected to a bottom mounting base, and the top end thereof connected to a top mounting base; a counterweight arranged in the support column; a car having a through hole penetrating in a vertical direction, wherein the car is arranged around the support column via the through hole; and a traction assembly, wherein the car is connected to the counterweight via the traction assembly, and the car and the counterweight reciprocate along the length direction of the support column under the traction of the traction assembly.

The present invention relates to a frame (20) for a car (10) of a passenger/freight elevator. The invention further relates to a car provided with such a frame. Finally, the invention also relates to an elevator comprising such a car. According to the invention the frame (20) comprises an upright (21, 22) having connected thereto a support (23, 24) which comprises two parts placed at an angle relative to each other, which parts are integrally connected. One part (23A, 24A) is connected here to the upright and the other part (23B, 24B) to a bottom part (33) of the car (10).

The elevator door panel is formed of a composite material based on reinforcement fibres embedded in a polymer matrix material, the reinforcement fibres being arranged in the polymer matrix material so that the elevator door panel is stiff in a vertical plane, but can be bent to a curve around a vertical corner.

A device for checking guides of an elevator car that can be moved along guide rails may include means for measuring contact forces of the guides on the guide rails. The device may further include an evaluation unit. The means for measuring contact forces may be configured to make measured values determined by the means for measuring contact forces available to the evaluation unit, either through wired connection or wireless connection. In some cases, the means for measuring contact forces may measure contact forces on the guide rails in at least two different directions. Also disclosed are methods for balancing elevator cars.

An elevator car panel configured to open and methods of opening the same. The elevator car panel includes a handrail configured on a first side of the elevator car panel and a locking mechanism configured on a second side of the elevator car panel, the second side opposite the first side. The handrail is operably connected to the locking mechanism such that movement of the handrail from a first position to a second position operates the locking mechanism to transition from a locked position to an unlocked position and, when in the unlocked position, the elevator car panel is openable.

According to a wireless power transfer system for wirelessly powering a conveyance apparatus of a conveyance system including: a wireless electrical power transmitter located along a side of the conveyance system in a first location; a power management system configured to control operation of the wireless electrical power transmitter; a wireless electrical power receiver located along a surface of the conveyance apparatus opposite the side; an energy storage device configured to receive electrical power from the wireless electrical power receiver; an energy storage device management system configured to monitor data of the energy storage device and the conveyance apparatus, the energy storage device management system being in wireless communication with the power management system, wherein the energy storage device management system is configured to transmit the data to the power management system and the power management system adjusts operation of the wireless electrical power transmitter in response to the data.

An elevator installation includes a shaft in which at least two elevator cars are arranged one above the other and are capable of travel upward and downward in a vertical direction separately from one another, wherein each elevator car is assigned a travel drive. The elevator cars are capable of travel with large and small spacings to one another without the risk of collision by coupling at least two elevator cars together by way of a variable-length, releasable coupling device, wherein the spacing between the coupled-together elevator cars can be varied, in a manner dependent on the relative speed between the two elevator cars, with the aid of at least one of the travel drives.
