Article 7. Hoistways, Hoistway Enclosures, and Related Construction for Power Cable-Driven Passenger and Freight Elevators

§3014. Guarding of Exposed Equipment.

(a) Guarding in Machine Rooms and Machinery Spaces. The following equipment located in machine rooms or machinery spaces shall be guarded to protect against accidental contact:

(1) Exposed external moving parts such as gears, sprockets, sheaves, drums, shafts and their driving ropes, chains or tapes for selectors, floor controllers or signal machines.

EXCEPTION to subsection 3014(a)(1):

Guards are not required for equipment located more than 7 ft (2.13m) above the floor.

(2) The nip points of the drive sheave of traction machines where the machine frame does not provide this protection.

(3) All moving parts of the equipment in secondary sheave spaces shall be completely guarded except the governor sheave and flyballs. Expanded metal or grillwork shall be used for secondary sheave guards.

EXCEPTION: Guards are not required for equipment located more than 7 ft (2.13m) above the secondary sheave space floor.

(4) The moving parts of equipment in overhead sheave spaces having a ceiling height of less than 78 in. (1.98m) shall be completely guarded except the governor sheave and flyballs.

(5) The moving parts of equipment in overhead sheave spaces shall be guarded when it is necessary to pass over or by the moving parts to gain access to the governor.

(b) Guarding in the Hoistway and On the Car. The following equipment located in the elevator hoistway or on the elevator car shall be guarded to protect against accidental contact:

(1) Hoisting rope sheaves attached to and mounted above the car crosshead shall be completely guarded. Handholds shall be provided on each side of the guard.

(2) Hoisting rope sheaves mounted within the car crosshead shall be provided with guards at the exposed nip points.

(3) Where secondary or deflecting sheaves are located on the hoisting side of overhead machines, the ropes shall be guarded at the point of contact with the sheave, except where the bottom of the sheave is more than 7 ft (2.13m) above the crosshead of the car when the car is at the top terminal landing.

(4) Where overhead sheaves are located above the crosshead, the ropes attached to the crosshead shall be guarded at the point of contact with the overhead sheave unless the sheave is located in an overhead sheave space.

(5) Ventilating fans or blowers installed on the car top shall be guarded.

(c) Rope Retainer Guards. Rope retainer guards shall be provided on deflector sheaves, machine sheaves, compensator rope sheaves, governor tension sheaves and hoist rope sheaves on cars and counterweights to inhibit displacement of ropes in the event ropes become slack.

Rope guards shall be continuous or there shall be one restraint for 30 degrees wrap or less, and two restraints for wraps in excess of 30 degrees. Where one restraint is furnished, it shall divide the arc of contact into equal parts. Where two restraints are furnished, they shall be located approximately 1/6 of the arc of contact from the nip points.

(d) Snag Guards. Snag points created by rail brackets, clip bolts and fishplates shall be provided with guards to prevent snagging of the following:

(1) Compensating cables on the counterweight end within 30 in. (762mm) of a counterweight rail bracket.

(2) Governor ropes located within 20 in. (510mm) of a counterweight rail bracket.

(3) Hoist ropes located within 12 in. (305mm) of a snag point.

(4) Traveling cables hung so any portion of their loop below the hatch junction box is within 36 in. (914mm) horizontally of a potential snag point.
