SECTION 27-1.1: MARKINGS 27-1.1.1 Placing Boom Rating and Identification Markings (a) The following information shall be legibly marked on a durable identification plate on the plac- ing boom: (1) manufacturer, supplier, or importer (2) year of manufacture (3) fabrication (serial) number (4) type or model (5) maximum design working pressure in the hy- draulic system (6) rated load (a) for placing booms, maximum weight per foot of delivery system when filled with material based on 150 lb/ft 3 (2 400 kg/m 3 ) (b) for conveyor, maximum weight of material per foot of belt (b) Power rating for electrical equipment above 24 V (voltage, frequency, power, amperage draw). (c) Placing booms shall be clearly marked with a la- bel affixed near the tip elbow warning about the use of improper diameter delivery system. (d) A durable plate showing the maximum weight of the hanging system components shall be attached to the boom tip. (e) Placing booms shall not be used to move freely suspended loads. A safety sign shall be placed on the machine to this effect. 27-1.1.2 Material Placement System Rating and Identification Markings The following information shall be legibly marked on a durable identification plate on the lower support struc- ture of the material placement system: (a) manufacturer, assembler, supplier, or importer (b) year of manufacture (c) fabrication (serial) number (d) type or model (e) maximum working pressure of material place- ment system hydraulic circuit(s) (f) maximum material pressure, if applicable (g) maximum working pressure supplied to the boom hydraulic system
27-1.1.3 Straight Delivery Pipes Rating and Identification Markings The following information shall be legibly and durably marked on straight delivery pipes longer than 12 in. (305 mm): (a) manufacturer or supplier (name or code) (b) nominal diameter (c) maximum working pressure, when new (d) weight of pipe per foot when filled with material based on 150 lb/ft 3 (2 400 kg/m 3 ) 27-1.1.4 Delivery System Elbow Rating and Identification Marking The following information shall be legibly and durably marked on delivery system elbows: (a) manufacturer or supplier (name or code) (b) nominal diameter (c) maximum working pressure, when new (d) weight of elbow when filled with material based on 150 lb/ft 3 (2 400 kg/m 3 ) 27-1.1.5 Delivery System Hose Rating and Identification Marking The following information shall be legibly marked on the delivery hose: (a) manufacturer (b) nominal diameter (c) working pressure when new (d) weight (1) for delivery hose, pounds per foot when filled with material based on 150 lb/ft 3 (2 400 kg/m 3 ) (2) for end hose, total weight [when filled with material based on 150 lb/ft 3 (2 400 kg/m 3 )] of compo- nent 27-1.1.6 Safety Signs Safety signs shall meet the requirements of ANSI Z-535, parts 1, 3, and 4. 27-1.1.7 Hand Signals Hand signals in accordance with para. 27-3.3.2 shall be posted conspicuously on the material placement sys- tem or placing boom.
(b) Attachment points shall be clearly marked for identification purposes. (c) Any component weighing more than 500 lb (227 kg) and having identified lifting attachment points shall have the component weight legibly and durably marked on the component. SECTION 27-1.3: WORK PLATFORMS, ACCESS WALKWAYS, AND GANGWAYS (a) Work platforms, access walkways, and gangways shall be a skid-resistant type. (b) Access for maintenance, assembly, dismantling, and testing should be provided. (c) The machine designer should consider weather conditions in the design phase to minimize adverse ef- fects, such as pooling of water and accumulation of ice and mud. (d) Access provisions for getting on and off the ma- terial placement system shall be in accordance with SAE J185. SECTION 27-1.4: ELECTRICAL INSTALLATIONS (a) Each electrically powered placing boom shall have a power disconnect switch mounted at or near the base of the placing boom. This switch shall have provisions to apply lockout/tagout procedures in accordance with ANSI Z244.1. (b) Electrical equipment shall be located or guarded so that live parts are not exposed to inadvertent contact under normal operating conditions. (c) Electrical equipment shall be protected from con- crete, dirt, grease, oil, and moisture infiltration. Fixtures, wiring, and connections exposed to the weather shall be of weather-resistant type. (d) Overload protection shall be provided for each in- dividual motor. SECTION 27-1.5: ERGONOMICS Control panels, manual override levers, access doors, and covers shall be located to provide access to accom- modate human physical dimensions as outlined in ISO 3411. SECTION 27-1.6: OUTRIGGERS (a) The machine shall be constructed so that the op- erator can see the area of outrigger movement from the outrigger control station. (b) Means shall be provided to hold all outriggers in the retracted position while traveling and in the ex- tended position when set for operating. (c) If equipped with detachable outrigger floats (feet), they shall be securable to the outrigger jack.
