| 3.3 - AUTHORIZED PERSONNEL | Persons who have been instructed in the operation and/or maintenance of the equipment and who are designated by the owner to use or maintain the equipment. |
| 3.4 - BRIDGING DEVICE | A device to span between the threshold of the car to the threshold of the landing. |
| 3.5 - BUFFER | A device designed to stop a moving car or counterweight beyond its normal limit of travel by storing or by absorbing and dissipating the kinetic energy of the car or counterweight beyond its desired limit of travel. |
| 3.5.1 - HYDRAULIC BUFFER | A buffer using fluid as a medium that absorbs and dissipates the kinetic energy of the moving car or counterweight. |
| 3.5.2 - HYDRAULIC BUFFER STROKE | The fluid-displacing movement of the buffer-plunger accelerating device. |
| 3.5.3 - SPRING BUFFER | A contact device that stores in a spring the kinetic energy of the moving car or counterweight. |
| 3.5.4. - SPRING BUFFER LOAD RATING | The load required to compress the spring an amount equal to its stroke. |
| 3.5.5 - SPRING BUFFER STROKE | The distance the contact end of the spring can move under a compressive load until all coils are essentially in contact or at the limit of their travel. |
| 3.6 - CAR | This section relates to car definitions. |
| 3.6.1 - CAR GATE CONTACT | An electrical device whose function is to prevent the normal operating device from moving the driving-machine unless the car gate is in the closed position. |
| 3.6.2 - CAR ENCLOSURE | The top and the walls of the car resting on and attached to the car platform. |
| 3.6.3 - CAR GATE MECHANICAL LOCK | A mechanical device whose function is to lock a car gate in the closed position as the car leaves the receiving landing and to prevent the gate from being opened unless the car is within the landing zone. |
| 3.6.4 - CAR FRAME (SLING) | The supporting frame to which are attached the car platform, upper and lower sets of guide shoes, backup guide shoe slides, car safety and hoisting ropes, hoisting rope sheaves or other lifting mechanism. |
| 3.6.5 - CAR PLATFORM | The structure that forms the floor of the car and directly supports the load. |
| 3.6.6 - HOIST CAR | The load-carrying unit, including its platform, car frame, car enclosure and car door or gate. |
| 3.7 - CAR SAFETY | See Safety, CAR or Counterweight. |
| 3.8 - CATHEAD | See overhead Structure. |
| 3.9 CHICAGO BOOM (JIB CRANE) | A lifting arm, derrick mounted on the hoistway structure or tower that is free to swing in the horizontal plane and is used for the purpose of hoisting materials and loading them into the building. |
| 3.10 CLEARANCE | This section related to clearance. |
| 3.10.1 - BOTTOM CAR CLEARANCE | The clear vertical distance from the pit floor (ground or foundation) to the lowest structural or mechanical part, equipment or device installed beneath the car platform, except guide shoes or rollers, safety-jaw assemblies and platform aprons or guards, when the car rests on its fully compressed buffers. |
| 3.10.2 - TOP CAR, ELEVATORS | The shortest vertical distance within the hoistway between the horizontal plane described by the top of the car enclosure and the horizontal plane described by the lowest part of the overhead structure or other obstruction in the hoistway when the car floor is level with the top terminal landing. |
