Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Alterations. Any change or addition to the equipment
						other than ordinary repairs or replacements.
Approved. The word "approved" means approved by the
						Division of Occupational Safety and Health.
Attendant. An individual assigned to particular duties or
						functions in the operation of a tramway.
Authority Having Jurisdiction. This term "Authority
						Having Jurisdiction" shall mean the Division of Occupational Safety and Health,
						State of California.
Bicable System. A system that uses separate cables to
						support and control motion of the carriers.
Bullwheel. A terminal sheave that deflects the haul rope
						150 degrees or more. When under power, the sheave is referred to as a drive
						sheave (or drive bullwheel); when acting as a movable tensioning device, it is
						referred to as a tension sheave (or tension bullwheel); and when it is acting
						simply as a fixed return for the haul rope, it is referred to as a fixed return
						sheave (or fixed return bullwheel).
Capacity.
Design Capacity. The capacity established by the designer
						as the optimum operating capability of the equipment, in the direction
						specified.
Operational Capacity. The capacity for which the
						installation has been tested and approved.
Chair. An open or partially enclosed carrier used on an
						aerial lift.
Conductor. An attendant assigned to duties or functions
						in an enclosed carrier.
Division. The word "Division" when used in these
						regulations shall mean Division of Occupational Safety and Health, State of
						California.
Existing Installations. Devices which have been inspected
						by the Division and to which an identification number has been assigned, or
						devices for which erection was begun before these regulations became effective
						and for which the notice of intent to install is not required, or devices
						erected from plans or contracts completed and for which the notice of intent to
						install was filed with the Division before these regulations became
						effective.
Gondola. An enclosed carrier used on an aerial
						lift.
Grips.
Haul Rope Grips. Those devices by which carriers are
						attached to the haul rope.
Detachable Grips. Those devices that are removed or
						detached from the haul rope at stations or terminals during normal
						operation.
Fixed Grips. Those devices that remain on the haul rope
						during normal operation.
Monocable System. A system that uses a single haul rope
						to both support and control motion of the carriers.
Operator. An individual in charge of a tramway, lift, or
						tow.
Overhauling. An operating condition in which unbalanced
						loading is sufficient to overcome line and drive friction and create a torque,
						acting to produce rotation of drive sheave in either direction when all brakes
						and the prime mover are inactive.
Qualified Engineer. An engineer, who by training and
						experience is qualified to design, survey, and supervise construction of
						tramways, lifts, or tows: and who is qualified under the Professional Engineers
						Act.
Rope and Strand.
Rope. Unless otherwise specified, the term "rope" shall
						mean wire rope, which consists of several strands twisted together.
(The terms "rope," "wire rope," and "cable" are
						interchangeable, except where, by the context, "cable" refers to a strand used
						as a track cable.)
Strand. Unless otherwise specified, the term "strand"
						shall mean wire strand, consisting of several wires twisted together (as
						compared with wire rope which consists of several strands twisted
						together).
Fiber Rope. A stranded or braided rope made from natural
						or synthetic fibers.
Shall. The term "shall" where used shall be construed as
						mandatory.
Sheaves. Pulleys or wheels grooved for rope.
Counterweight Sheave. A sheave used in the counterweight
						roping system that is active during normal operations.
Deflection Sheaves. A terminal sheave that deflects the
						haul rope at least 10 degrees but less than 150 degrees.
Diameter of a Sheave. Wherever the term "diameter" is
						used in specifying sheaves, it refers to the diameter at the bottom of sheave
						grooves (tread diameter).
Haul Rope Sheaves. Sheaves that support or hold down the
						haul rope at towers or terminals. (The angle of deflection is usually
						small.)
Rollers. Sheaves of small diameter used to guide or
						restrain the rope from leaving its proper alignment.
Terminal Sheaves. A haul rope sheave at a terminal that
						rotates continuously when the haul rope is moving and deflects the haul rope by
						an angle of 10 degrees or more.
Should. The term "should" where used shall be construed
						as advisory.
Stop Gate. A type of automatic stopping device that, when
						actuated by a passenger's weight, contact, or passage, will automatically stop
						the tramway.
Supervisor. An individual in responsible charge of aerial
						passenger tramway operations and personnel.
Track Cable Saddle. A component designed to directly
						support a track cable.
Track Rope or Cable. A stationary wire rope used to
						support a carrier or carriers on a bicable serial tramway.
