✔✔A car traveling in the hoistway always stops at the same spot and blows a fuse.
What causes this? - ✔✔Traveling cable has a cut/exposed wire or a short

,✔✔A 300ohm resistor burns out, but you don't have another one. How can you make
one? - ✔✔2 600ohm resistors in parallel is 300ohms. Resistance is half of highest
resistor in parallel circuit.

the output voltage? - ✔✔320vac
3 phase full wave = 1.33x output voltage
✔✔A car is loaded with 125% and sinks, why? - ✔✔Slipping through the break
✔✔If you find a broken or missing barricade what should you do? - ✔✔Write up a formal
inspection request
✔✔What are the consequences of misaligned joints on a Rack and Pinion? - ✔✔Broken
Gear teeth. CWT derailment. Excessive wear/ crease the surface of the tube

capacity? - ✔✔9 x 4 x 13.9= 500lbs Max capacity
✔✔You must enter a pit with a toxic atmosphere, how do you proceed? - ✔✔Following
proper OSHA procedure with proper training and PPE
✔✔When changing a 1:1 car rated at 600fpm and 2,000lb capacity to a 2:1, what are
the new ratings? - ✔✔300fpm 4,000lbs capacity
Half the speed, Double the capacity
✔✔A vertical platform lift has a clearance of 1 inch. How much will it have to move to
meet code? - ✔✔Move in ¼ inch. Code is ¾ inch
✔✔A car weighs 2500lbs with a capacity of 2500lbs, the CWT is weighted at 40%, how
much is the motor lifting when the car is fully loaded? - ✔✔2500(car) + 1000(40%)
3500. 5000-3500=1500lbs lifted by the machine
✔✔How must Oxygen and Acetylene tanks be stored? - ✔✔Vertically, 12 feet apart, or
on a cart with a ½ hour fire barrier between them
✔✔What is code for sill to sill distance? - ✔✔Minimum ½ inch Maximum 1 ½ inches
, ✔✔When drilling a jack hole in sandy conditions what type of drill rig is required? -
✔✔Rotary or Auger bit. Rotary=Soft Percussion=Rocky Combo=Solid
✔✔A customer does not want an escape hatch on a residential elevator, under what
condition is this legal? - ✔✔Manual operation must be provided
✔✔Your helper wired the down direction and final limit switches, now the car will only
travel up, what is the issue? - ✔✔The down direction limit was wired incorrectly.
✔✔What are the effects of one rope sitting deeper in the sheave groove? - ✔✔The rope
wears out and breaks faster
✔✔There is a noise coming from a freight door. The sheave is moving, but the chain is
not. What is the problem? - ✔✔Oil on the drive chain
✔✔What is the effect when you change a sling angle from 60 degrees to 30 degrees? -
✔✔More tension, less capacity. Any angle 30 or less is dangerous
✔✔How many points of a contact must be maintained on a ladder? How far above
landing must it extend? What is proper Ratio? What steps don't we use? - ✔✔3 points
of contact. 3 foot above. 4:1. Top 2 steps
✔✔You open a dumbwaiter access panel and it still runs, what is the problem? - ✔✔Pit
access switch is not working properly
✔✔You perform a static load test with the pit valve closed. The car sinks 6" in 15
minutes. What is the problem? - ✔✔Cylinder leak
✔✔Where should you aim a fire extinguisher to put out a fire? - ✔✔At the base of the
fire
✔✔Car with selective collective system is moving to the lobby to take a call, an up call is
put in at the 2nd floor, what happens? - ✔✔The call is bypassed until the car is traveling
up
✔✔During construction you land an escalator, but it is 10mm low, what is wrong? -
✔✔The pit is too deep or column MARK is off
✔✔During construction the Omega CWT rails have been damaged, what happened? -
✔✔The Omegas were over tightened
