persons with impaired mobility – ules forsafety, dimensions and functional
operation— Part 1: Vertical lifting platforms.
3.13
driving rack
strip incorporating specially shaped teeth with which a driving pinion may engage to form a positive driving means converting rotary motion into linear motion
3.14
driving screw
externally threaded driving component that acts in conjunction with a driving nut
3.15
duty cycle
number of journeys the lifting platform is required to perform in a given period of time
3.16
enclosed liftway
liftway in which the space is fully bounded by the bottom of the pit and a solid enclosure (but not necessarily a ceiling) and/or landing doors reaching to a height above the highest position of the platform enclosure
NOTE See example in Figure 1.
3.17
final limit switch
electrical safety switch, positively and mechanically operated by the lifting platform in the event of overtravel
3.18
follow-through
amount of additional free movement provided in the actuation of an electrical switching device after the electrical contact has been broken
3.19
full-load pressure
highest hydraulic system pressure for the lifting platform carrying its rated load when at rest
3.20
guide rail
components which direct the course of the platform
3.21
guided chain
chain, which may be either fixed or moving, and which is completely guided over its entire length such that it may transmit a load either in thrust or tension
3.22
hydraulic lifting platform
lifting platform in which the lifting power is derived from an electric motor, driving a pump which transmits hydraulic fluid to ajack
3.23
journey
movement of the platform between any two levels which incorporates one start and one stop
3.24
landing
defined level to be served by the lifting platform, having adequate space to permit the manoeuvring, boarding and alighting of users with a wheelchair where appropriate
3.25
lifting platform
device permanently installed to serve fixed landing levels, comprising a guided platform whose dimensions and means of construction permit the access of disabled passenger(s), with or without wheelchair(s)
3.26
protected space in which the platform travels
3.27
machine space
space in which the drive unit and/or the associated equipment is placed
3.28
mechanical blocking device
device which, when set in position, guarantees a minimum safety space beneath the platform for the purposes of maintenance and inspection
3.29
non-enclosed liftway
liftway which is not enclosed
NOTE See example in Figure 1.
3.30
overspeed governor
device which, when the lifting platform attains a pre-determined speed, causes the lifting platform to stop by application of the safety gear
3.31
pinion
wheel, having machine-cut teeth specially designed to engage with those of other similar toothed wheels or racks, used to transmit relative motion
3.32
platform
flat and substantially horizontal structure that is part of a lifting platform that supports a user or users
3.33
pressure-relief valve
valve which limits fluid pressure to a stated value by exhausting fluid
3.34
rack
bar with specially shaped teeth with which a pinion may engage and which forms a positive driving means to convert rotary motion into linear motion
3.35
rated load
load for which the equipment has been built and for which safe operation is guaranteed by the supplier
3.36
rated speed
nominal speed of the lifting platform as agreed in the contract for the particular installation
3.37
restricted access
access which is restricted to a known user or users
3.38
rupture valve
valve designed to close automatically when the fluid pressure drop across the valve, caused by increased flow in apredetermined flow direction,exceeds a predetermined amount
3.39
safety circuit
electrical or electronic circuit which has been subjected to failure analysis to confirm an equivalent degree of safetyto a safety contact
3.40
safety contact
contact in which the separation of the circuit-breaking elements is made by positive means
3.41
safety factor
ratio, for a particular material under static or dynamic conditions (as defined in the text), of the yield load or theultimate tensile load (as defined in the text) to the load that can be imposed upon a member by the rated load.
