SECTION 13-0.1: SCOPE OF B30.13
Within the general scope defined in Section I, ASME B30.13 applies to storage/retrieval (SIR) machines and associated equipment, such as aisle-transfer cars and aisle equipment (as defined in para. 13-0.2.1), and interlaces with other material-handling equipment covered under other standards. The provisions of this Volume applying to S/R machines shall apply equally to the construction, installation, inspection, testing, maintenance, and operation of aisle-transfer cars and any load-handling equipment that is part of or attached to S/R machines or aisle-transfer cars.
SECTION 13-0.2: DEFINITIONS
13-0.2.1 Types of Equipment
storage/retrieval (SIR) machine: a machine operating on floor or other mounted rail(s) used for transferring a 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 Figure 13-0.2.1-1.
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 Figure 13-0.2.1-2).
automatic SIR machine: an S/R machine that, when activated, operates through a preset program cycle or cycles.
operator-ridden SIR 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 manually or automatically (see Figure 13-0.2.1-3).
22 13-0.2.2 GeneraL
aisle conductors: electrical feeders along the runway that provide power to the equipment.
automatic or automatically: pertains to equipment functions that 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 means of friction or power.
(b) Brakes shall be provided for horizontal travel and shall be applied automatically when power to the brake is removed, but shall not prohibit the use of a drift point in the control circuit.
(ç) Brakes shall be provided with means to compensate for lining wear.
(d) The wearing surfaces of all brake wheels, drums, or disks shall be free of defects that interfere with the operation.
(e) Holding-brake torque shall be sufficient to decelerate the S/R machine from rated speed by at least I ft/sec2 (0.3 m/s2) and shall be capable of decelerating the SIR machine to a complete stop from rated speed.
(f) Brakes shall have thermal capacity for the frequency of operation required by the service.
SECTION 13-19: ELECTRICAL EQUIPMENT
13-1.9.1 GeneraL
(a) The provisions of this Section shall only apply to S/R machines, aisle-transfer cars, and any load-handling equipment that is part of or attached to SIR machines or aisle-transfer cars.
(b) If resistor enclosures are provided, they shall be installed to prevent the accumulation of combustible matter.
(c) Wiring Outside of Control Enclosures on an SIR Machine or Aisle-Transfer Car
(1) Conductors external to control cabinets shall be enclosed in raceways or be protected cable, such as but not limited to types ALS, CS, or Ml cable, subject to the exception that contact conductors, that are fully insulated except as necessary to provide access for collector shoes. may be used to service moving portions of such machines,
(2) Rubber, thermoplastic, or synthetic polymer insulation may be used in accordance with ANSI/NFPA 70, Table 3 10-2(a).
(3) The allowable ampacities of conductors shall be as shown in ANSI/NFPA 70, Table 610-14(a). For the ampacities of conductors between controllers and resistors, see ANSI/NFPA 70, Section 430-23. The ampacities of conductors within flexible cords or cables shall be in accordance with ANSI/NFPA 70, Article 400.
(4) Individual conductors run in conduits and race- ways or within jacketed multiple conductor wire shall not be smaller than No. 16.
(5) Flexible cords or cables that are part of special sensors or appliances and that conform to ANSI/N FPA 70, Articles 400 and 725 may be used in short runs outside conduits or raceways.
(d) Wiring Within Control Enclosures
(1) When an S/R machine carriage is operator- ridden, the wiring shall be flame-retardant and moisture-resistant.
