Abstract: The object of the invention is a traction sheave elevator and a rope that contains metal as a load-bearing material, such as the suspension rope of an elevator, which rope comprises at least one or more strands laid from metal wires and which rope is lubricated with a lubricant. Another object is the use of the aforementioned lubricant for lubricating the rope. The lubricant comprises at least oil and thickener, which thickener in the lubricant comprises at least 10% or more of the mass of the lubricant.

Abstract: The invention relates to a method for monitoring the condition of the door of an elevator and determining its need for maintenance, the door comprising a door mechanism, door panels and a door operator. The signals (10) of the control system of a door in good condition are measured and a set of characteristics descriptive of the operation of the door is generated from them. The signals (10) of the door control system are measured the operation during the opening and closing movements of the door is divided into stages according to which parts of the door are functioning at each stage. From the measured signals (10), a set of characteristics descriptive of the operation of the door is generated. The set of characteristics thus generated is compared to the set of characteristics for a normal operating condition stored in memory, at least in one stage of operation.

Abstract: A control circuit for use with an electronic guard strip for preventing collision of the strip with a moving object. A control such as a relay, is connected to at least one antenna, which antenna forms a capacitor together with a base in its ambiance. A voltage generator conducts an alternating voltage to the antenna. The control and the antenna are connected in circuit relation to an amplifier. A change of voltage arising from any capacitive protuberation in the antenna is conducted to the control. The voltage from the amplifier is conducted through a rectifier to another amplifier that is connected so as to have its direct current gain as +1, but which amplifies any change of voltage occurring in the d.c. voltage input to a multiple and which further acts upon the control through a comparator.
