ASME B30.13:2022 pdf download.Storage/Retrieval (S/R) Machines and Associated Equipment
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 Volume 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 that is part of or attached to S/R machines or aisle-transfer cars.
storage/retrieval (S/R) 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 thatnormally runs on a rail or rails (see Figure 13-0.2.1-2). automaticS/Rmachine:anS/Rmachinethat, whenacti- vated, 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 canbe controlledeithermanu- ally or automatically (see Figure 13-0.2.1-3).
aisle conductors: electrical feeders along the runway that provide power to the equipment. automatic or automatically: pertains to equipment func- tions 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.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 the equipment. 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. carriage-mountedcab:anoperator’scabthatisattachedto the carriage ofan S/R machine and moves vertically with the carriage. clearance: the distance between loads, structure, and equipment calculated to allow for operating and installa- tion tolerances, deflections, load displacement, and load integrity. collectors: contacting devices for collecting current from aisle conductors. control braking: 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 components and circuits. design load: the maximum length, width, height, and weight of a load handled, including any pallet, container, slave pallet, or stacking tolerances. driftpoint:apointonatravel motionmasterswitchorona manual controllerthatmaintains the brake releasedwhile the motor is not energized. This allows for coasting. emergency-stop switch: a manually or automatically oper- ated switch to cut offpower independently ofthe regular operating controls. hoistchain: 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. limit sensor: a device that is operated by some part or motion of a power-driven machine or equipment to alter the circuit associated with the machine or equip- ment. load sizing: a process to determine that the loads are dimensionally acceptable for storage. machine aisle: space between storage compartment rows in which the S/R machine operates. manual operation: pertains to equipment functions that require action by the operator. master switch: a switch that dominates the operation of contactors, relays, or other remotely operated devices. normalservice: service thatinvolves operatingatless than 85% ofthe rated load and notmore than 10 lift cycles/hr, except for isolated instances.
