(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‘ided 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 clearances 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.
(Ii) Means shall be provided to limit horizontal displacement of a pallet or container on a carriage toward the operator.
(i) Materials which will propagate combustion or rekindle 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 of 10 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 walkways, 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 provided as required for access to controls and other maintenance items.
13-1.6.2 Construction of Platforms
(a) Platforms shall be designed to sustain a distributed load of at least 50 lb/sq ft (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. (1067 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) x 27 in. (685 mm) protected with a hinged hatch cover.
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 of 250 lb (113 kg), concentrated at such a point which will cause maximum stress in the structural member being considered.
(b) rungs shall have a minimum diameter of 34 in. (19 mm), a maximum distance between rungs of 12 in. (305 mm), and a minimum clear width of 16 in. (406 mm).
(c) a minimum climbing space of 15 in. (381 mm) each way from the centerline of the ladder and 30 in. (762 mm) on the climbing side of the ladder shall be provided except when inside cages or hatchways are used.
(d) the distance from the centerline of the rungs to the nearest permanent object in back of the ladder shall be not less than 7 in. (178 mm).
(e) on ladders over 20 ft (6 m) in height, cages shall be provided from a point not more than 8 ft (2.4 m) above the floor, to a point not less than 3 ft 6 in. (1.1 m) above the landing platform unless safety devices as per para. 13-1.6.3(f) are provided. Such cages shall be at least 27 in. (685 mm) clear inside diameter.
(fi ladder safety devices may be used on ladders over 20 ft (6 m) in unbroken height in lieu of cage protection. All ladder safety devices such as those that incorporate life belts, friction brakes, and sliding attachments shall meet the design requirements of the ladders that they serve.
(g) when exiting at the top of the ladder, handrails of at least 3 ft 6 in. (1.1 m) shall extend vertically from the top level of the ladder; otherwise, the ladder will extend an additional similar distance above the point of exit.
