ASME B30.27:2005 pdf free download.Material Placement Systems.
out rigger: extendahle or fixed members attached to the mounting base, which rest on supports at the outer ends used to support the machine.
placing booms: manual or power driven, slewable working devices, consisting of one or more extendable or foldable parts supporting the material delivery system, and directing the discharge into the desired location.
priority switching: transferring control of one or more functions from a control location to a different control location.
qiuilfed person: a person who, by possession of a recognized degree in an applicable field, or certificate of professional standing, or who by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter and work.
ratel load: maximum allowable working load designated by the manufacturer.
rrmote control: a portable control device connected to the machine by a wire cable or linked by radio or other means.
safrty device: a means placed in use for the specific purpose of preventing an unsafe condition.
siwave: a grooved wheel or pulley used with a rope to change the direction and point of application of a pulling force.
short rigging: one or more outriggers not fully extended on the side away from the boom operational area.
sigiral person: see spotter.
specfic type (r’matcrthl piacenwnt sysh’m): a model, style, or size classification of material placement system (e.g.. three section boom, four section boom, 50 meter class, conveyor).
spotter: a signal person/spotter is a person positioned at a vantage point where both the point of discharge and the operator of the material placement system can be seen and relays information to the operator.
SECTION 27-1.6: OUTRIGGERS
(a) The machine shall be constructed so that the operator can see the area of outrigger movement from the outrigger control station.
(h) Means shall he provided to hold all outriggers in the retracted position while traveling and in the extended position when set for operating.
(C) If equipped with detachable outrigger floats (feet), they shall be securable to the outrigger jack.
(d) The maximum downward force imposed by the outrigger shall be marked at each outrigger.
(e) Power-actuated jacks, where used, shall be provided with the means (such as integral load hold check valves on hydraulic cylinders, mechanical locks, etc.) to prevent loss of support under load.
SECTION 27-1.7: CONTROLS AND INDICATORS
27-1.7.1 Emergency Stops
(a) Each machine shall be equipped with an emergency stop system.
(b) The emergency stop system actuator(s) shall be visible, accessible, and easy to operate.
(c) The machine shall be equipped with an emergency stop actuator at control panel(s) and at the remote control device(s). The machine maybe fitted with additional emergency stop actuators.
(d) Emergency stops shall
(1) cause the machinery to stop instantaneously, taking into account stored energy.
(2) prevent the automatic restart of the machine. The machine will have to be started intentionally.
(3) be constructed according to ISO 13$50.
27-1.7.2 OutrIggers
(a) Control devices for slewable, telescopic, or adjustable outriggers shall return to the neutral position when released.
(b) Control devices for outriggers shall be situated outside of the area of outrigger movement, or access to the area of outrigger movement shall be otherwise restricted.
(c) Control circuits for the outriggers shall be independent of each other.
(d) Outrigger control systems shall be designed so they are nonfunctional when the machine is locked-out in accordance with ANSI Z244.1.
27-1.7.3 General Control Requirements
(a) If there are multiple control locations, the same operation (e.g.. start, close, open) shall only be possible from one location at a time. Priority switching (either manual or automatic) shall be used to transfer the control behceen the control locations.
