    Abstract: A transport equipment comprises at least a carrier that is disposed on the window platform or balcony and thus becomes one part of a building in normal condition, or that is pushed out of the window or balcony for personnel and commodity transportation through a cantilever beam of a slow descending mechanism when in need, to descend or ascend along the outer wall of a building. In this manner, personnel or commodity can be transported by the carrier to reach ground directly or in relay-floor connection mode. For example, personnel or precious commodity can be evacuated at the first instant of fire. Even in the case of electricity disconnection due to the happening of a fire, the slow descending mechanism of the transport equipment can be operated by uninterruptible power supply or by hand.
