    Abstract: A ladder support bracket has a support shoulder for creating a support contact with a complementary backup. The bracket includes at least one jaw for joining the bracket to an upstanding rail of a ladder, the jaw having also a retainer mechanism by means of which the bracket—when being attached to a rail of a ladder—can be brought into a clamping position attaching the bracket unmovably to the rail and a release position holding the bracket in a swivel connection relative to the rail and/or movably along at least a section of such rail.

    Abstract: An elevator includes an elevator car and lifting machinery including a traction sheave, an electromechanical machinery brake, and an electric motor having a rotor. The traction sheave, the electromechanical machinery brake and the rotor of the electric motor are connected via a shaft, whereby the lifting machinery moves the elevator car upwards and downwards in a vertically extending elevator shaft controlled by a main control unit. The direction of rotation and the rotation speed of the rotor of the electric motor is detected with a sensor, the amplitude of the brake current provided to the machinery brake is measured, the amplitude of the brake current is increased until a first moment when the shaft and thereby also the rotor of the electric motor starts to rotate, which is detected by the sensor, the brake current is disconnected momentarily at the first moment, the torque acting on the shaft and the corresponding load in the elevator car at the first moment is determined based on the measured amplitude of the brake current at the first moment, whereby said torque is used in the main control unit for controlling the lifting machinery.
