§3158. Definitions.

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.
