3.1

rated load

load for which the MCWP has been designed for normal operation, as stated in the load diagram

3.2

load diagram

notice displayed on the work platform showing the permitted number of persons and the mass and distribution of materials for the particular configuration

3.3

rated speed

vertical or horizontal speed for which the MCWP has been designed

3.4

transfer

any horizontal movement of the MCWP from one position to another on the same working site

3.5

transfer condition

configuration of the MCWP in which it is moved from one position to another on the same working site, including any limitation on the weather and the load or persons on the MCWP

3.6

transport

any movement of the MCWP outside the boundaries of the working site

3.7

transport condition

configuration of the MCWP in which it is moved outside the boundaries of the working site

3.8

transfer [transport] interlocks

any design features on the MCWP which prevent unsafe transfer [transport]

3.9

base frame

part of the MCWP which provides support for the mast and elevating assembly

3.10

chassis

part of the MCWP which provides mobility and support for the mast and elevating assembly

3.11

rail-mounted chassis

chassis designed to transmit horizontal as well as vertical force to the ground via rails

3.12

outrigger

support at the base-frame level used to maintain or increase the stability of the MCWP within specified conditions

Note 1 to entry: Outriggers can also be used for levelling.

3.13

outrigger beam

part of an outrigger assembly which moves in an essentially horizontal plane and may be powered or operated manually

3.14

mast

structure that supports and guides the platform

3.15

fixed-length mast

mast whose length cannot be varied, even by the attachment of further mast sections

3.16

variable-length mast

mast whose length can be varied by the attachment of successive lengths of prepared sections

3.17

guide

part of the mast which provides guiding for the work platform

3.18

mast tie

anchorage system used to provide lateral restraint to the mast from a building or other structure

3.19

work platform

vertical travelling part of the installation upon which the persons, equipment and materials are carried and from which work is carried out

Note 1 to entry: The work platform includes the main platform and any platform extension, in contrast to the MCWP, which refers to the whole of the installation, including work platform, mast, mast ties, base and chassis.

3.20

available platform area

area of the work platform, measured at the work platform floor level

3.21

main platform

part of the work platform built up using primary structural elements

3.22

platform extension

additional part of the work platform, built up using secondary structural elements, whose support and location is dependent upon the main platform

Note 1 to entry: Platform extensions are used to extend the main work platform, usually along its longitudinal working edge. They can form irregular shapes which conform with the work site. They can also extend at a level just above or below the main platform level.

3.23

multilevel work platform

two or more work platforms travelling on the same mast or an additional working level attached to and totally supported by a work platform

Note 1 to entry: For illustration, see Annex B.

3.24

counter-roller

roller used to counteract the gear-meshing separation forces between a rack and pinion

3.25

automatic brake

device to decelerate and stop moving parts in case of interruption of the power supply

3.26

buffer

stop at the end of travel, comprising a resilient means of arrest using fluids, springs or similar means

3.27

overspeed

any speed above rated speed

3.28

overspeed detector

device which, when the work platform attains a predetermined speed above rated speed, causes the overspeed safety device to be applied

3.29

overspeed safety device

mechanical device for stopping and maintaining the work platform stationary on the mast in the event of overspeed

3.30

competent person

person having the practical and theoretical knowledge and the experience of a particular MCWP needed to carry out a function satisfactorily

3.31

user

user organization

person or organization having direct control over use of the MCWP

3.32

rack and pinion drive system

drive system using a gearing arrangement consisting of a cylindrical gear (pinion) which engages a linear gear (rack) attached to the mast

3.33

ratchet drive system

drive system that operates by attaching a ratcheting device to the rungs or other element of the mast in an alternating manner and elevates or lowers the platform a predefined distance

Note 1 to entry: The platform can be supported by a pawl or similar device when the drive mechanism is not engaged.

3.34

screw drive system

drive system consisting of a mast-mounted rack which meshes with a powered drive screw attached to the platform
