The invention is an elevator. The elevator is driven by a rack and a chain. The elevator also comprises a transportable frame, a floor, and an elevator shaft. The purpose of the invention is, by using a rack and chain lifting device to drive the elevator, to allow the elevator to be driven from the bottom. Driving the elevator from the bottom makes the structural integrity of the elevator box unnecessary, so that the elevator box can be replaced with an elevator box façade and a fabric door, making the elevator lighter and more economical. In addition, the design of the elevator allows for adjacent doors, battery power, and voice control.

The invention is a corner rack with one front face that has teeth. A corner rack is a linear gear interface that can be placed in corners, such that the teeth face out from the corner at an angle, rather than running parallel with the walls. The teeth of the corner rack have a profile that can engage with the profile of a silent chain. The combination of the corner rack and silent chain allows an attached motor to be distanced from the corner rack, so that a lifting device driven by the corner rack and silent chain can be placed in and utilized in corners. This leads to increased versatility and efficiency.

An arrangement for overcoming heights or vertical distances, such as, in particular, high-voltage towers, towers for wind installations, buildings, high-bay warehouses, etc., has a longitudinally extended, rail-like profile (7) or guide member, and at least one portable lift element which is releasably fastenable to the profile, consisting of a driving part (3) which is movable up and down along the profile or guide member and a platform (5) for receiving at least one person or loads.

A lift system for moving a car along a track in a guided manner. The lift system having a guide rail system, a car and a drive unit arranged on the car. The guide rail system forms a closed track along which the car can be moved between floors when in operation. The drive unit has a motor, a gear wheel system connected to the motor by a shaft and a guide disk. The guide rail system has a pinion system and guide edges spaced apart from one another, which cooperate with the guide disk. When in operation, the motor drives the gear wheel system and the gear wheel system acts on the pinion system in order to move the car along the track in a guided manner.

A transport mechanism for transporting a travel body that can self travel and includes: a motor; a drive wheel to which rotary torque of the motor is transmitted; and a first gear to which the rotary torque of the motor is transmitted is provided. The transport mechanism includes: a transport body configured on which the travel body is placed for transportation, the transport body including a second gear that can mesh with the first gear of the placed travel body; a movement mechanism for moving the transport body, on which the travel body is placed, by the rotary torque of the motor transmitted to the second gear; and an idling section for causing an idle state in which the drive wheel rotates idle in a state where the first gear and the second gear mesh with each other and rotation of the second gear is permitted.

A mast climber, including a mast and a platform, is disclosed. The mast is comprised of at least two segments, including a bottom segment and one or more body segments. Each segment has a sidewall that is made of sheet metal, and most segments may be made of a lightweight metal, such as a aluminum. Each segment has at least one gear rail assembly, and may have two gear rails, disposed on opposite corners of the mast. A platform is adapted to be connected to the mast. The platform is equipped with a drive system that moves the platform up and down the mast. The drive system includes one or more electric motors on the platform and batteries to power the electric motors. Each motor has a gear that engages one of the gear rails. A backup power supply or generator may be provided.

An advanced warehouse and logistic system having a hinged rack lattice structure that allows multiple autonomous mobile lift robots to move independently through the hinged rack structure to move goods and load trucks and other vehicles. The autonomous mobile lift robot of the present invention comprising a plurality of driving trains having a first gear mounted perpendicularly to a second gear to have the autonomous mobile lift robot be movable in an up, down, left, and right direction through the hinged rack depending on the geometry of the hinged rack lattice structure.

An elevator that incorporates a framework that allows multiple autonomous mobile lifts to move independently inside and outside a building or a group of buildings in shafts and corridors in such a way that multiple lifts can share a shaft and/or corridor.

An elevator installation erection method includes installing in an elevator shaft: a construction phase elevator system having a self-propelled elevator car whose usable lifting height is adapted to an increasing elevator shaft height; at least one guide rail in the elevator shaft guiding the elevator car along its travel path; and a drive system driving the elevator car and including a primary part attached to the elevator car and a secondary part attached along the elevator car travel path, wherein the guide rail and the secondary part are gradually extended upwards during the construction phase, wherein the self-propelled elevator car transports persons and/or material for the construction of the building and passengers and freight for floors already used as residential or business premises, and wherein after the elevator shaft has reached its final height the construction phase elevator system is replaced by a final elevator system.

Lifting devices for residential, public and industrial buildings and structures, and more specifically, lifting and carrying systems for maintaining building facades, having rail or mast-type guides, which are arranged on the external wall of the building and equipped with teeth, and a lifting device with a drive including a motor with a gearbox, and a toothed wheel mounted on the drive shaft of the gearbox to engage with the teeth of the guides so that, when the toothed wheel rotates, the lifting device moves along the guides. The shapes of the guides duplicate that of the building, and they are attached to the building by brackets passing through the building facade and secured to load-bearing structures of the building. The lifting device has a platform, each edge of which is hinged to a frame connecting two carriages each having a system of guiding thrust rollers supported on the guides.
