An modular lift system for hoisting objects along a track to a predetermined height. The lift system may include a limit switch, a carriage with an automatic emergency braking system, and a peak to engage the track, whereby the carriage rolls along the side rails of the track between the peak mounted to the top of the track and the bottom of the track. The carriage can be adjustable thereby permitting it to be adapted to various types and sizes of tracks. The automatic emergency braking system is adapted to prevent the uncontrolled descent of the carriage in the event of a cable or primary brake failure.

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.

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.

A knockdown, portable lift is relatively compact and lightweight for transport and use where there is no existing means for lifting a load between a lower surface and an upper surface or where the existing means cannot be used. Components of the lift are stored in a base portion of the lift and are assembled on site for forming a lift frame extending between the upper and lower surfaces. A platform and drive assembly are supported on the lift frame and are driven together up and down tracks on each side of the lift frame using a rotary drive, such as a hand crank or electric motor, to power the drive assembly. The drive assembly is operable by a person on or off the platform from either the upper or lower surface or traversing stairs over which the platform is moving. The drive assembly incorporates a unique overspeed braking system and a unique clutch arrangement.

A method of using a material hoist system can include extending an overall length of a track assembly by slidably moving a second track member of the track assembly with respect to a first track member of the track assembly; and slidably moving a carriage of the system with respect to the track assembly.
