An elevator system arranged in an elevator shaft of a building in the construction phase grows with the building using a lifting process. The system includes a machine platform with an elevator drive machine and an elevator car suspended on the machine platform by a carrier. The elevator car is raised during the lifting process by a lifting device. The elevator system also includes an assembly platform that can be mechanically moved in relation to the machine platform along the elevator shaft. The lifting device includes a drive arranged on the machine platform and is also used to move the assembly platform.

An elevator of the present invention includes a guide member spaced apart from a structure and formed in a vertical direction with respect to the ground, a first elevating member coupled to the guide member to be moveable in a longitudinal direction of the guide member, a second elevating member coupled to the guide member to be moveable in the longitudinal direction of the guide member, detachably coupled to a lower side of the first elevating member, and lifted and lowered together with the first elevating member, and at least one connecting unit which connects the first elevating member and the second elevating member.

An installation device used in an elevator shaft has a first carrier with first and second carrier ends, a support element pivotably arranged on the first carrier end, and a holding apparatus holding a displacement apparatus by which installation material can be displaced in the elevator shaft. When the installation device is in an installation position, the first carrier end is supported against a threshold of an elevator shaft door opening by the support element and the second carrier end is supported at least indirectly against a shaft wall that is opposite the door opening. The holding apparatus is arranged on an upper side of the installation device in the installation position such that the displacement apparatus is supported from above on the holding apparatus.

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.

A construction site elevator system temporarily bridges at least part of the distance between the top stop of a jump lift and the top work level on the construction site. The construction site elevator system includes a frame structure and an elevator within the frame structure, the frame structure being configured to be insertable into an elevator shaft and being mountable at different positions in the elevator shaft.

A lifting assembly, a jump elevator and a jumping method. Wherein the lifting assembly comprises: a supporting platform provided with a plurality of telescopic first pawls at the side face thereof; at least one screw mechanism comprising a screw and a sleeve, the screw and the sleeve each being provided with an external thread and an internal thread matching with each other; and a driving mechanism configured to drive one of the screw and the sleeve to rotate in relative to the other, such that the screw mechanism extends or retracts; wherein the screw mechanism is connected between the supporting platform and the operating platform, one of the screw and the sleeve is configured to be rotatably attached to one of the supporting platform or the operating platform.

A containment unit that facilitates delivery of parcels using drones is provided. An example containment unit comprises an inner housing unit and an outer housing unit. The inner housing unit includes a first and second sidewall that are connected by an end piece and have a bottom opening in between. The inner housing unit is movable from a retracted position over a floor of the containment unit to an extended position, where a portion of the opening is extended beyond the floor. A parcel may be inserted into a volume of space within the inner housing unit from below through the opening and pulled into the containment unit by the end piece when the inner housing unit is retracted. The containment unit can be used as part of a drone delivery system that can also include an elevated delivery platform, a computer application, or any combination of these aspects.

An elevated delivery platform having a delivery surface that can be placed at a location off the ground to better facilitate delivery of parcels by unmanned aerial vehicles, such as delivery drones, is provided. By placing the elevated delivery platform in an area above the ground, such as atop a home or a pole, a drone is more capable of making deliveries because it avoids obstacles nearer to the ground that typically make drone delivery challenging. The elevated delivery platform raises and lowers parcels to a position where they can easily be retrieved. Some systems also provide a deployable cover to protect parcels from adverse weather conditions while awaiting pickup or following delivery. The elevated delivery platform can be used as part of a drone delivery system that can also include a containment unit, a computer application, or any combination of these aspects.
