CSLB

The California C-11 Elevator license exam is a 3.5-hour, computer-based, multiple-choice test administered by PSI. It requires 4 years of journey-level experience, a $450 application fee, and covers planning and estimating (17%), conveyance system installation (34%), repair/maintenance/modernization (24%), and safety (25%).

Sample CSLB C-11 Practice Questions

Try these sample questions to test your CSLB C-11 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1During the planning phase of a traction elevator installation, which drawings are the primary source for verifying required clearances between the cab and hoistway walls?
A.The approved elevator layout and the manufacturer's installation drawings
B.The general contractor's interior finish schedule
C.The project electrical panelboard schedule
D.The mechanical HVAC drawings showing ductwork and equipment layouts for the building
Explanation: The elevator layout and manufacturer installation drawings define hoistway inside dimensions, cab-to-wall clearances, and runner gaps. Other trades' schedules do not establish the vertical-transportation envelope.
2When scheduling an escalator installation, which activity typically consumes the most building crane time?
A.Mounting the main drive motor on the upper truss
B.Installing the comb plates at the landings
C.Setting the truss sections into the wellway
D.Hanging the interior balustrade panels
Explanation: The escalator truss is the heaviest single component and is normally set in one or two crane picks into the wellway; it drives the rigging schedule. Motors, comb plates, and balustrade are lighter work performed after the truss is landed.
3When ordering suspension ropes for a 2:1 roped traction elevator, the estimator must account for the roping factor. Compared to a 1:1 roping at the same rated car speed, the rope velocity in a 2:1 system is:
A.The same as the car speed
B.Twice the car speed
C.Half the car speed
D.Four times the car speed
Explanation: In 2:1 roping the rope travels twice the car speed because the car is supported through a deflector sheave on the car frame, doubling rope travel for a given car movement. This affects rope length and sheave RPM calculations.
4An electric traction elevator has an empty car weight of 4,500 lb and a rated capacity of 3,000 lb. If the counterweight is balanced at 45% of rated capacity, what is the required counterweight weight?
A.5,400 lb
B.5,700 lb
C.6,000 lb
D.5,850 lb
Explanation: Counterweight = empty car weight + (balance coefficient x rated capacity) = 4,500 + (0.45 x 3,000) = 4,500 + 1,350 = 5,850 lb. The balance coefficient typically ranges 0.40 to 0.50 for traction elevators.
5Before beginning demolition of an existing elevator in an occupied building, the C-11 contractor's job plan must first include which step?
A.Locking out and tagging out the elevator disconnect and notifying the AHJ
B.Scheduling the cab finish replacement crew
C.Ordering replacement hoistway door gaskets
D.Notifying floor tenants of new cab lighting and coordinating lobby renovation access
Explanation: Taking the existing unit out of service requires locking and tagging the main line disconnect and notifying the AHJ (elevator inspector) before any demolition. Finish, gasket, and lighting work comes after the unit is secured.
6What is the primary function of elevator guide rails?
A.To carry the vertical load of the cab and passengers
B.To guide the car and counterweight and provide a surface for the safeties to grip
C.To act as the electrical grounding path for the controller and reduce stray current noise
D.To support the weight of the counterweight ropes
Explanation: Guide rails constrain the lateral motion of the car and counterweight and provide the friction surface that car and counterweight safeties clamp during an overspeed stop. The ropes carry vertical load; rails are not structural load members or electrical grounds.
7When installing guide rails, what is the acceptable method for correcting an out-of-plumb condition at a bracket location?
A.Shim between the rail and the bracket with approved steel shims, then recheck plumb
B.Bend the rail at the bracket until plumb
C.Weld the rail directly to the building structural steel for a permanent rigid connection
D.Loosen all lower brackets until the rail self-aligns
Explanation: Rails are plumbed using approved steel shims at the bracket to bring the rail face within tolerance, then rechecked with a plumb bob or laser. Bending, welding to structure, or loosening brackets would damage the rail or create unsafe alignment.
8On a traction elevator, what is the purpose of the hoistway door interlock?
A.To lock the cab gate from the inside
B.To silence the door operator motor
C.To prevent the car from running unless all hoistway doors are closed and locked
D.To hold the landing door open during freight loading and bypass the safety circuit
Explanation: The door interlock is an electrical and mechanical device that prevents the elevator from operating unless every hoistway door is fully closed and locked, protecting passengers from falling into the hoistway. It is not a cab-side lock or a motor control.
9Which statement about traction sheave grooves is correct?
A.Worn grooves increase traction and should be left in service
B.All sheave grooves must be lubricated daily to maintain traction and reduce rope wear
C.The sheave diameter may be smaller than the rope diameter
D.V-grooves provide higher traction than U-grooves but cause faster rope wear
Explanation: V-grooves bite into the rope more aggressively, giving higher traction than U-grooves, but the sharper contact accelerates rope wear. U-grooves are gentler; lubrication is applied per manufacturer specs, not daily; sheave diameter must exceed rope diameter by a large ratio.
10On a high-rise traction elevator, what is the purpose of the compensating chain or rope?
A.To replace the main suspension ropes with a secondary set during modernization
B.To balance the suspension rope weight and maintain equal sheave tension
C.To act as an emergency brake on the counterweight
D.To supply traveling power to the cab
Explanation: Compensating chains or ropes hang from the bottom of the car and counterweight and cancel out the changing weight of the suspension ropes as the car moves, maintaining equal rope tension across the sheave. Without compensation, traction would vary between up and down trips.
