output voltage? - ANS- 320 VAC
3 phase full wave= 1.33 x output voltage. - 715
A car is loaded with 125% and sinks, why? - ANS- Slipping through the brake
IF you find a broken or missing barricade what should you do? - ANS- Write up a formal
inspection request
What are the consequences of misaligned joints on a rack and pinion? - ANS- Broken
gear teeth. CWT derailment. Excessive wear/crease the surface of the tube. - 850
, A dumbwaiter is 9 sqft in area, 4 ft in height, and capacity is 13.9lb/ft. What is the total
capacity? - ANS- 9 X 4 x 13.9= 500lbs Max Capacity

proper OSHA procedure with proper training and PPE - 133
When changing a 1:1 car rated at 600fpm and 2,000lb capacity to a 2:1, what are the new
ratings? - ANS- 300 fpm with 4000lbs capacity. Half the speed and double the capacity.
A vertical platform lift has a clearance of 1 inch. How much will it have to move to meet
code? - ANS- Move in 1/4 inch. Code is 3/4 in
A car weighs 2500lbs with a capacity of 2500lbs, The CWT is weighted 40% , how much is
the motor lifting when the car is fully loaded? - ANS- 2500 (CAR) + 1000 ( 40%)= 3500lbs
5000-3500= 1500lbs lifted by the machine - 240
How must Oxygen and Acetylene tanks be stored? - ANS- Vertically, 12 feet apart, or on
