摘要： A system and a process are provided for uniformly recording and storing compliance and maintenance information independent of specific conveyance apparatus service provider. Such a system and a process assists the jurisdiction and all parties involved in these service areas with documenting all work performed, documenting work that needs to be performed, accessing the necessary information to make sure the work is performed properly and timely, and enforcing the scheduled maintenance requirements for the conveyance apparatus to reduce liability for the parties responsible for the maintenance.

摘要： A descent device includes a load carrier, a winder unit with a coil of cable for suspending the load carrier in mid-air so as to raise or lower the load carrier, and a retarding unit for impeding downward movement of the load carrier so that the load carrier can move downward at a lower speed to ensure safety of the occupants.

摘要： An illustrative example embodiment of an elevator governor includes a rotatable governor mechanism, a tension sheave, and a tension frame associated with the tension sheave. The tension frame has a mass configured to bias the tension frame and the tension sheave under an influence of gravity. A damper is configured to resist vertical movement of the tension frame relative to a fixed surface in a first condition and to allow vertical movement of the tension frame relative to the fixed surface in a second, different condition.

摘要： A hydraulic elevator up direction control system is provided that has a circulating valve connected between the supply and the return of a source that normally supplies pressure to the cylinder of an elevator. The circulating valve is controlled by a computer regulated stepless variable solenoid valve that influences the pilot fluid pressure in the operating chamber of the circulation valve to control the size of the opening of the circulating valve and thereby the volume of fluid passing through the circulating valve. This affects inversely the volume of fluid passing through a fluid flow measuring valve, to the cylinder, to provide selectably variable up speeds of travel facilitating a fast, smooth, accurate ride of the elevator car as it approaches a stopping point relative to an upper floor of a building. Such operation is substantially independent of the system pressure and fluid viscosity. A selectably variable speed down direction control system operates on largely the same principle.

摘要： A mechanism for controlling the movement of an elevator car has a helical frame which is threadedly advanced in synchronism with the car. The helix passes under a control head which is mounted on an arm pivoted about the axis of the helix. The control head is rotated through a limited arc by the arm in a direction opposite to the direction of rotation of the helix as the car begins to move. Displacement of the arm from the neutral position generates a speed reference signal and establishes the advance car position relative to floor stops mounted on the helical frame at points proportional to the location of the landings. When the car is to be stopped, a pawl on the control head is dropped and the car is slowed down as the floor stop engages the pawl and returns the arm to the neutral position. Various switches associated with other control functions such as door opening are operated at selected points in the travel of the control head and arm.
