Section 3087.1 - Definitions. [4]

Actuator. A manually operated device that initiates the action of controls or controllers.

Antirunaway (Safety Stop). A safety device to stop and hold the uncontrolled descent of a platform or carrier.

Backstop. A mechanical device to prevent reversal of a loaded vertical or inclined reciprocating conveyor under action of gravity when upward travel is interrupted.

Bracing. Structural members used to stabilize the supporting structure.

Brake. A friction device for slowing down conveyor components, bringing conveyor equipment to a controlled stop, holding traveling equipment at a selected landing, preventing reverse travel, and controlling overspeed due to the action of gravity.

Carrier or Platform. The moving part of a vertical or inclined reciprocating conveyor that supports the load.

Control. The system governing the starting, stopping, direction of motion, acceleration, speed, retardation identification, and function of the moving member in a predetermined manner.

Controller. An electromechanical device or assembly of devices for starting, stopping, accelerating, or decelerating a drive, or serving to govern in the predetermined manner the power delivered to the drive.

Conveyor Vertical or Inclined. A hydraulically or mechanically powered reciprocating device exclusively designed for moving freight (not to carry passengers or an operator) vertically or on an incline between two or more landings and/or between different levels on a single floor.

Counterweight. Weights in a structural frame used to balance or impose a load.

Drive. An assembly of the necessary structural, mechanical, and electrical parts that provides the motive power.

Emergency Stop. A stop resulting from a sudden and unexpected need, and not as part of the normal operation.

Emergency Stop Switch. A device that must be actuated in an emergency situation to stop a conveyor.

Enclosed. Describes the guarding of moving parts in such a manner that physical contact by parts of the body is precluded as long as the guard remains in place.

Guard. A covering or barricade to prevent entry into operating components such as gear, chain, or nip points.

Guarded. Shielded, fenced, enclosed, or otherwise protected by means of suitable enclosure, covers, casing shields, troughs, railings, or by nature of location as to reduce forseeable injury.

Guarded By Location. Describes moving parts so protected by their remoteness from the floor, platform, walkway, or other working level, or by their location with reference to frame, foundation, or structure as to reduce the forseeable risk of accidental contact by persons or objects.

Nip point. A point at which moving or rotating machinery components may entrap persons or objects by nipping, pinching, or squeezing.
