Within the general scope defined in Section I, ASME B30.13 applies to storage/retrieval (S/R) machines and associated equipment, such as aisle transfer cars and aisle equipment (as defined in para. 13-0.2.1), and inter- faces with other material handling equipment covered under other standards. The provisions of this Standard applying to S/R machines shall apply equally to the construction, installation, inspection, testing, mainte- nance, and operation of aisle transfer cars and any load handling equipment which is part of or attached to S/ R machines or aisle transfer cars.
storage/retrieval (S/R) machines: a machine operating on flooror othermounted rail(s) used fortransferringa load from a storage compartment to a pickup and deposit (P and D) station and from a P and D station to a storage compartment. The movement of the storage/retrieval machine may be both vertical and parallel in the aisle. A storage/retrieval machine is sometimes called a storage crane or S/R machine, but it is different from a stacker crane. A typical unit load storage/retrieval machine is shown in Fig. 1. aisle transfer car: a machine or vehicle for transferring an S/R machine from aisle to aisle and that normally runs on a rail or rails (see Fig. 2). automatic (S/R) machine: an S/R machine which when activated operates through a preset program cycle or cycles. operator ridden (S/R) machine: an S/R machine, with a cab attached to the machine and with an operator in the cab, whose movements can be controlled either manu- ally or automatically (see Fig. 3).
13-0.2.2 General
administrative or regulatory authority: governmental agency or the employer in the absence of governmental jurisdiction. aisle, machine: space between storage compartment rows in which the S/R machine operates. aisle, pedestrian: a walkway designated for pedestrian traffic. ampacity: current-carryingcapacityofelectric conductors expressed in amperes. appointed: assigned specific responsibilities by the employer or the employer’s representative. authorized: approved by a duly constituted administra- tive or regulatory authority. automatic or automatically: pertains to equipment func- tions which do not require the attention of the operator during their functional operation. brake: a device, other than a motor, used for retarding or stopping motion by friction or power means. buffer: an energy dissipating device for reducing impact when a moving S/R machine reaches the end of its permitted travel, or when two moving S/R machines come into contact. bumper: an energy absorbing device for reducing impact when a moving S/R machine reaches the end of its permitted travel, or when two moving S/R machines come into contact. cab: the operator’s compartment on an S/R machine. cab, carriage mounted: an operator’s cab which is attached to the carriage of an S/R machine and moves vertically with the carriage. carriage: that part of an S/R machine by which a load is moved in the vertical direction. carriage free fall stop: a mechanism used to prevent or stop uncontrolled descent of the carriage in event of loss of support.conductors, aisle(s): electrical feeders along the runway that provide power in the S/R machine or aisle trans- fer car. control braking means: a method of controlling speed by removing energy from the moving body or by imparting energy in the opposite direction. control voltage: electrical voltage used in the control com- ponents and circuits. designated person: a person selected or assigned by the employerorthe employer’s representative asbeingcom- petent to perform specific duties. drift point: a point on a horizontal travel motion master switch or on a manual controller that releases the brake while the motor is not energized. This allows for coasting. fault conditions: a malfunction caused by overload, travel beyond set limits, emergency stop, or failure of compo- nents essential to safe operation of the S/R machine or aisle transfer car. hoist: a machinery unit which is used for lifting and lowering. hoist chain: a roller or calibrated link chain in a hoist that supports the carriage. hoist motion: the motion of a storage crane that lifts and lowers the carriage.
