Disclosed is an elevator inspection system, configured to inspect multiple elevator cars in a group of elevator cars, the system having: a sensor implement; a robot supporting the sensor implement; and a controller operationally connected to the robot and the senor, wherein the controller is configured to transmit an alert responsive to determining, from sensor data compared with elevator operational data, that an operational parameter of an elevator car in which the robot is located is outside a predetermined threshold.

Elevator inspection system with robot configured to inspect operational conditions of elevator car

Disclosed is an elevator inspection system, having: a sensor implement; a robotic platform supporting the sensor, the robotic platform configured to inspect a hoistway; a controller operationally connected to the robotic platform and the sensor, wherein the controller is configured to define hoistway model data for the hoistway, from sensor data, corresponding to locations and shape boundaries of the hoistway and doorway openings formed in the hoistway.

Disclosed is an elevator inspection system, the system having: a robotic platform configured to inspect a hoistway; a platform propulsor operationally connected to the robotic platform; and a controller operationally connected to the platform propulsor, wherein the controller is configured to control the platform propulsor to propel the robotic platform vertically within the hoistway.

Elevator inspection system with robotic platform configured with a platform propulsor

Disclosed is an assembly having: at least one drive wheel configured to roll against a hoistway rail of an elevator system; and a drive mechanism supported by the assembly and configured to drive the at least one of drive wheel, wherein the assembly is configured to support one or more sensors.

Inspection assembly for elevator system

A method of avoiding unnecessary safety brake actuation in an elevator system. The method includes determining whether a true overspeed or overacceleration condition of an elevator car is present. The method also includes activating the electronic safety actuator if a true overspeed or overacceleration condition of the elevator car.

Method and system of reducing false actuation of safety brakes in elevator system

Erectable shelter frame structures including a plurality of rib assemblies. Preferably, each rib assembly has a receptacle for receiving a respective end of a purlin arrangement, the other end of which is attached to a receptacle of a subsequent rib assembly. The joints are formed by toggle clamps that assist in facilitating the ease by which the shelter structure can be assembled or disassembled. Methods of construction and disassembly of the shelter frame structure are also disclosed.
