Abstract: An elevator car defining an interior space for accommodating passengers and/or cargo, comprising a support frame positioned above the interior space, a working platform moveable between a stowed position, above the interior space, and an operational position, within the interior space and at least one extendable suspension arrangement arranged to suspend the working platform from the support frame. The extendable suspension arrangement includes a connection plate, a first arm member connected at a first end to the support frame and slidably connected to a first connection point of the connection plate and a second arm member connected at another first end to the working platform and slidably connected to a second connection point of the connection plate.

Abstract: A monitoring system for a conveyance system includes a pressure sensor mounted on a conveyance apparatus; an accelerometer mounted on the conveyance apparatus; and a controller arranged to: acquire accelerometer data by sampling the accelerometer; store the accelerometer data in a buffer; acquire pressure sensor data by sampling the pressure sensor; determine from the pressure sensor data that a start or stop of the conveyance apparatus has occurred; and upon said determination, analyse the accelerometer data to determine a first position within the accelerometer data, wherein the first position is a position at which the start or stop of the conveyance apparatus occurred. Both pressure and acceleration readings are combined to determine a point in time at which motion started or stopped. The pressure sensor is used first to determine a robust indication that the motion state has changed (started or stopped).
