Question #354

Mechanical safety devices found on mobile elevating work platforms include:

Zabezpieczenia typu mechanicznego spotykane w podestach ruchomych przejezdnych to:

a
a tilt sensor, a STOP switch, an audible signal

czujnik przechyłu, wyłącznik STOP, sygnał dźwiękowy

b
pawls, scrapers, rail clamps

zapadki, zgarniacze, kleszcze szynowe

c
guardrails, toe boards, guards

barierki, krawężniki, osłony

Correct answer

d
support feet, clutches, gearboxes

łapy oporowe, sprzęgła, reduktory

Why?

Guardrails (barierki), toe boards (krawężniki) and guards (osłony) provide physical protection between a person or object and a hazard. A tilt sensor and a STOP switch act through the control system, so they do not belong to this group of mechanical safeguards.
