Question #335

The telescopic boom of a mobile elevating work platform:

Wysięgnik teleskopowy podestu:

a
has a mechanical system for changing outreach

posiada mechaniczny układ zmiany wysięgu

b
consists of several sections

składa się z kilku członów

c
enables safe work near power lines

umożliwia bezpieczną pracę przy liniach elektroenergetycznych

d
answers a and b are correct

odpowiedź a i b jest prawidłowa

Correct answer

Why?

A telescopic boom (wysięgnik teleskopowy) consists of several sections that extend and retract to change its outreach (wysięg). It therefore has a mechanical system for making this adjustment, which does not mean it must be manually powered. Telescopic construction alone provides neither electrical insulation nor safe working conditions near power lines.
