13-1.3.4 Modifications S/R machines may be modified or rerated, provided suchmodifications and the supportingstructure are ana- lyzed by a qualified person or the manufacturer. A rerated machine or one whose load-supporting compo- nents have been modified shall be tested in accordance with para. 13-2.2.2. New rated load or design load shall be displayed in accordance with para.
13-1.1.1. SECTION 13-1.4: CABS 13-1.4.1 Cab Location on an Operator Ridden S/R Machine (a) The general arrangement of the cab and location of the control equipment shall be such that all devices necessary to select, initiate, or terminate an automatic cycle or to start or stop each manually controlled opera- tion are within convenient reach of the operator. (b) The cab shall be clear of all fixed structures within its area of possible movement.
13-1.4.2 Cab Construction (a) The cab interior construction should protect the operator from knobs, edges, or corners in the event of sudden crane accelerations or decelerations. (b) The cab should be constructed and installed to minimize swaying or vibration. (c) In the absence of an outside platform, the door, if provided, shall open inward or slide and be self-closing. It shall be equipped with positive latching devices to prevent inadvertent opening. (d) Emergency exit means to the floor shall be pro- vided for all positions of a carriage-mounted cab. (e) While the machine is in motion, all parts of the operator’s body shall be kept within the design clear- ances by the construction of the cab, by hands-on, feet- in-place operating type controls, or by mechanical restraints interlocked with motion controls. (f) All cab glazing shall be safety glazing material as defined in ANSI Z26.1. (g) The crane operator shall be protected from falling objects at the normal work station. The protection required shall be based upon the materials being stored and their height. Protection such as an overhead guard or cab location is acceptable. The operator protection shall be designed by a qualified person. (h) Means shall be provided to limit horizontal dis- placement of a pallet or container on a carriage toward the operator. (i) Materials that will propagate combustion or rekin- dle shall not be used in the construction of the cab. 13-1.4.3 Fire Extinguisher A portable fire extinguisher, with a basic minimum extinguisher rating of10 BC, shall be installed in the cab.
13-1.4.4 Lighting Cab lighting, either natural or artificial, shall provide a level of illumination that enables the operator to observe the operating controls.
SECTION 13-1.5: LUBRICATION Lubricating points should be accessible from walk- ways, floor(s), or platforms without the necessity of removing guards or other parts. SECTION 13-1.6: PLATFORMS, LADDERS, AND PERSONNEL ACCESS TO AISLES AND RUNWAYS 13-1.6.1 Location of Platforms Service platforms, fixed or removable, should be pro- vided as requiredforaccess to controlsand other mainte- nance items.
13-1.6.2 Construction of Platforms (a) Platforms shall be designed to sustain a distrib- uted load of at least 50 lb/ft 2 (2.4 kPa). (b) Platforms shall have a slip-resistant walking surface. (c) Handrails for platforms shall be 36 in. (915 mm) to 42 in. (1 067 mm) high with an intermediate rail and a 4 in. (102 mm) to 6 in. (152 mm) toeboard. (d) Ladder access openings in the platform floor should be approximately 24 in. (610 mm) ? 27 in. (685 mm) protected with a hinged hatch cover. (e) When platforms are provided for personnel who ride on the carriage outside the cab, they shall be equipped with the following: (1) a flat slip-resistant surface upon which to stand, either on the carriage or on a portable platform/surface attached to the carriage (2) a fall arrest anchorage at shoulder height or higher, meeting the requirements of ASSE Z359.1 (3) a means of communication between the opera- tor and the person on the carriage (4) a means of “emergency stop” that is available to the person on the carriage (5) a handhold for each person on the carriage 13-1.6.3 Fixed Ladders Fixed ladders, if provided, shall meet the following requirements: (a) the minimum design live load shall be a single concentrated load of250 lb (113 kg), concentrated atsuch a point that will cause maximum stress in the structural member being considered. (b) rungs shall have a minimum diameter of 3 ⁄ 4 in. (19 mm), a maximum distance between rungs of 12 in. (305 mm), and a minimum clear width of 16 in. (406 mm).ASME B30.13 pdf download.ASME B30.13-2017 pdf free download
