ASME B30.27:2005 pdf download Material Placement Systems
SECTION 27-0.1: SCOPE
Volume B30.27 includes provisions that apply to theconstruction,installation, operation,inspection, and maintenance of mobile material placing booms, mobile telescoping boom conveyors,separate placing booms,andmaterial placement accessories (see Figs.1 through 3).This Volume does not apply to the pumping elements of a concrete pump, conveyors, mortar conveying or spraying machines, or dry mix shotcreting machines.
The concrete pump portion of these machines is covered by CPMA 27-2000.
The conveyor section of these machines is covered byASME B20.1.
SECTION 27-0.2: DEFINITIONS
concrete delivery hose: a flexible delivery hose having acoupling on each end.
control panel: controls mounted on the material placement system.
delivery systems: delivery lines, pipes, hoses, attachmentcomponents, and transfer valves, through which material is transported (see Fig. 4).
designated person: a person selected or assigned by theemployer or the employer’s representative as beingcompetent to perform specific duties.
end hose: a flexible concrete delivery hose that only hasone coupling.
mantlal palve override: a mechanical valve actuator usedto operate an electrically controlled valve in emergencyor breakdown situations.
manllal malves: a valve whose manual actuator is the onlymeans of valve actuation.
maximumm support force: the maximum force exerted onthe supporting surface at any one outrigger.normal operating conditions: conditions during which amaterial placement system is performing functionswithin the scope of the original design. Under these conditions, no one other than the operator is on the material placement system.
oufrigger: extendable or fixed members attached to themounting base, which rest on supports at the outer endsused to support the machine.
placing booms: manual or power driven, slewable work-ing devices, consisting of one or more extendable orfoldable parts supporting the material delivery system,and directing the discharge into the desired location.
priority stitching: transferring control of one or morefunctions from a control location to a different controllocation.
qualified person: a person who, by possession of a recognized degree in an applicable field, or certificate of professional standing,or who by extensive knowledgetraining, and experience, has successfully demonstratedthe ability to solve or resolve problems relating to thesubject matter and work.
rated load: maximum allowable working load designatedby the manufacturer.
remote control: a portable control device connected to themachine bv a wire cable or linked by radio or other meanssafety device: a means placed in use for the specific pur-pose of preventing an unsafe condition.
sheave: a grooved wheel or pulley used with a rope tochange the direction and point of application of apulling force.
shortrigging: one or more outriggers not fully extendedon the side away from the boom operational area.signal person: see spotter
specific type (of material placemenf system): a model, style, orsize classification of material placement system (eg., threcsection boom, four section boom, 50 meter class, conveyor)spotter: a signal person/spotter is a person positioned ata vantage point where both the point of discharge andthe operator of the material placement system can beseen and relays information to the operator.
