tripping speed.
Car doors are dragging on the sill. How high should they be raised to be code compliant? -
ANS-¼"
Car is loaded with 125% and sinks. Why? - ANS-Slipping through the break
Car will not travel to2nd floor without a 3rd floor call, and will not go down from 3rd without a
2nd floor call. What is the problem? - ANS-2FI4/6
During construction the omega CWT rails have been damaged. Why? - ANS-Overtightened
from rail bracket. (215)
During construction you land an escalator, but it is 10mm too low. What is wrong? - ANS-Pit is
to deep or column mark is off.( 825)
Given a generator runs at 600 RPM and has 4 poles is the output frequency ? - ANS-600/60
sec=10x2=20Hz
How do emergency doors swing? - ANS-outwards
How do you cut a finished floor material? - ANS-Cutting blade away from the finish
How do you handle a coworker who shows up to work intoxicated? - ANS-Speak to the MIC,
Union BA or call your Supervisor.
How do you test the safety circuit? - ANS-You test all switches Independently.
How does a GFI work? - ANS-Detects an imbalance between Hot and Neutral Wires
How is a class 1 yearly buffer test preformed? - ANS-Car at bottom landing and on inspection,
jump out direction and final limits. With pit clear, run down to compress buffers, buffers should
fully extend within 90 seconds.
5yr: Full load Full speed
CWT: Full speed Empty

ANSWER 11
How much resistance is measured over a normally closed switch? - ANS-1.2ohms. should be
zero, but will
never be that low
