ASME B30.25-2003 pdf download.SCRAP AND MATERIAL HANDLERS.
(c) The function of all controls (except as noted) shall be clearly identified by symbols on affixed labels or diagrams conforming to SAE J1362. Words may be used to complement such symbols or when appropriate symbols have not been standardized. All symbols shall be explained in the operator’s manual along with control movement and sequence. The horn control shall be identified by a label or diagram.
(1) The function of controls obviously self-defined by standard practice such as steering wheel, turn signal, etc., or by mounting location such as heater switch or door handle when located on the unit are not required to be labeled.
(2) Where possible, the movement of all controls from their neutral position shall be in the same general direction as the movement of the functions that they control. In their neutral position, there shall be no movement of the functions.
25-1.5.2 Travel Controls
(a) Primary travel controLs affect the following basic travel functions: speed, steering, travel direction, service brake (if provided), and clutch (if provided). Secondary controls affect other travel functions (if provided) such as transmission selector, emergency brake, parking brake, turn signal, etc.
(b) The location and direction of movement of the primary travel controls for wheel-mounted and crawler- mounted handlers are illustrated and described in Figs. 8 and 9, respectively. The direction of movement of functions that are controlled (forward, reverse, etc.) are relative to the handler in its normal mode as specified by the manufacturer.
25-1.5.3 Front Controls
(a) Primary front controls actuate the following on all handlers: boom, stick or arm, swing, magnet, grapple, and jib, if so equipped.
(b) Secondary front controls actuate other front functions (if provided) such as a combination grapple magnet.
(c) The location and direction of movement of the front controls and their functions are illustrated in Figs. 10 and 11. The direction of movement of the functions that are controlled (right, left, etc.) is relative to the operator when sitting in the operator position. An optional switch should be provided to allow switching of the front primary controls between attachments. This switch should be mounted on the console or other suitable location and shall be labeled to identify its function.
(d) The control arrangement shown in Figs. 10 and 11 are for the primary controls only, and shall be located within the zones as set forth in SAE J898.
(e) The arrangement of secondary and auxiliary controls is not shown; however, they shall be so located as not to interfere with the operation of the primary controls.
(ft When more than one control location is offered for a function or function(s), one location should conform to the recommended practice. Other control locations and arrangements shall be at the discretion of the manufacturer or assembler/modifier.
(g) Control actuating forces shall comply with the values set forth in SAE J1814.
(h) The distance between control levers, adjacent foot pedals, handles, knobs, and other handler parts shall be sufficient to allow operation without unintentional actuation of adjacent controls. See SAE J1814 for suggested minimum clearances. The overlapping of controls is permissible to provide independent and simultaneous control application.
25-1.5.4 AuxilIary ControLs
Auxiliary controls actuate all other functions that pertain to overall handler performance such as outriggers/ stabilizers, engine speed, engine start and stop, swing brakes, horn, and steering selector.
SECTION 25-1.6: CABS
25-1.6.1 ConstructIon
(a) All cabs and enclosures shall be constructed to protect the upper-structure machinery and operator’s station from the weather.
(b) All cab glazing shall be safety glazing material as defined in ANSI Z26.1. Windows shall be in all sides of the cab or operator’s compartment. Visibility forward shall include a vertical range adequate to view the attachment when it is in its normal operating position. The front window may have a section that can be readily removed or held open. If the section is of the type held in the open position, it shall be secured to prevent inadvertent closure. The front window shall meet the requirements of ANSI Z26.1, Class 1.
