Question 1
In low-rise applications, hydraulic elevators typically do not require an _____ _____ room.
A) adjacent equipment
B) overhead machine
C) basement control
D) exterior motor
E) auxiliary power
Correct Answer: B) overhead machine
Rationale: Hydro elevators, especially in low-rise applications, do not need an overhead
machine room because the pumping unit can often be located in a separate machine room,
often at grade level, as the plunger (jack) supports the car from below.
Question 2
What are some advantages of hydraulic elevators regarding equipment and building construction
costs?
A) Higher equipment costs due to complex controls.
B) Requires extensive building structural support for the load.
C) Lower equipment and building construction costs because the load of a hydro is carried to the
ground, whereas the load of a traction car is carried by the building structure.
D) Faster installation time compared to traction elevators.
E) Requires more vertical space in the hoistway.
Correct Answer: C) lower equipment and building construction costs because the load of a
hydro is carried to the ground where as the load of a traction car is carried by the building
structure.
Rationale: A major advantage of hydraulic elevators is that the entire weight of the car and
its load is directly supported by the jack and transferred to the ground, requiring less
building structural support compared to traction elevators where the load is borne by the
building's overhead structure.
Question 3
When drilling the jack hole for a hydraulic elevator, what is the only proper way to determine if
the hole is plumb (perfectly vertical)?
A) Use a spirit level on the drill stem.
B) Visually inspect the drill bit.
C) Use a laser level from the top of the hoistway.
D) Remove the drill stem and bit and use a spider bob.
E) Measure the depth at multiple points around the circumference.

Correct Answer: D) remove the drill stem and bit and use a spider bob.
Rationale: The only accurate method mentioned for determining the plumb of a jack hole is
to remove the drilling equipment and use a specialized tool called a spider bob, which is
suspended into the hole to check for vertical alignment.
Question 4
To plumb the jack hole, a spider bob is attached to a length of piano wire suspended from where?
A) The pit floor.
B) The ground level, outside the hoistway.
C) As near as possible to the top of the hoistway or from a fixed point on the drill rig.
D) The top of the car sling.
E) An adjacent building structure.
Correct Answer: C) as near as possible to the top of the _____ or from a fixed point on the
drill rig.
Rationale: For accurate plumbing, the spider bob's piano wire must be suspended from a
stable, high point directly above the hole, such as near the top of the hoistway or from the
drill rig itself, to ensure vertical reference.
Question 5
When welding a joint, a specific sequence of tack welds is described. How are these tack welds
applied?
A) Two 1-inch tack welds 90 degrees apart.
B) Four 1-inch tack welds 45 degrees apart.
C) Lay 1-inch tack welds 180 degrees apart, shift it 90 degrees and lay two more 1-inch tack
welds 180 degrees apart.
D) Three 1-inch tack welds 120 degrees apart.
E) Continuous full-length welds are preferred.
Correct Answer: C) lay 1-inch tack welds 180 degrees apart, shift it 90 degrees and lay two
more 1 inch tack welds 180 degrees apart.
Rationale: This specific sequence of applying tack welds (1 inch, 180 degrees apart, then
shifting 90 degrees for two more 1 inch tack welds 180 degrees apart) is a method to
prevent warping of the cylinder during the welding process by distributing heat evenly.
Question 6
On power units having the motor beneath the tank, the pump may be either _____ driven or
_____ coupled.
A) chain, gear
B) belt, direct
C) hydraulic, electric
D) piston, rotary
E) cable, shaft
