Duty cycle as defined in IEC 60034-1: Intermittent periodic operation
with the motor active at most 30% of the time.
Alternating Current.
Cover to prevent direct contact between people, rain, dust and the
motor gearbox.
In the length direction of the shaft.
Torque to which a bolted joint has to be tightened in units of in Newton-
metre.
Intensity of sound, expressed in decibels
A counter used to register the number of actual operating hours of the
drive unit.
Temperature-sensitive protective switch.
A coupling which is able to compensate for alignment errors, for instance
a chain coupling, universal joint or cardan shaft.
Emergency switch actuated by a pull cord spanned along the entire
length of the system.
The voltage, current and power values for which and electric motor is
designed and which are shown on rating plate of the motor.
The area below or directly around the driven or moving parts.
An overriding or governing switch condition, depending on the structure
of the system, such as a rain signal that causes automatic operation of
the motor gearbox.
A measure of the rotational effect of a force. The magnitude of the
torque is equal to the force time the radius (arm) and is expressed in
Newton-metres.
Straight line
A gear unit that reduces the shaft speed of the input shaft.
Perpendicular to the shaft.
A switch operated by an electromagnet.
Risks which cannot reasonably be avoided (inherent in the product).
Hoisting equipment.
Revolutions per minute.
AC voltage
A protective device which stops descending loads if they are moving too
fast.
An electrical contact that opens when the switch is actuated.
Fluidity or thickness of a liquid.
The gear unit can only be driven by the motor the output shaft cannot
be moved by the load.
