Subpart CC
This requirement applies to cranes with a manufacturer-rated hoisting/lifting capacity greater than 2,000 pounds. See 1926.1433(a).
Crawler, truck, and locomotive cranes manufactured before November 8, 2010 must meet either ANSI B30.5-1968, PCSA Std. No. 2 (1968), the requirements in paragraph (b) of 1926.1433, or the DIN standards that were in effect at the time of manufacture. See 1926.1433(a) and 1926.1433(b).
Mobile (including crawler and truck) and locomotive cranes manufactured on or after November 8, 2010 must meet the specific portions of ASME B30.5-2004 listed in paragraphs (b)(1) through (b)(16) of 1926.1433. See 1926.1433(b).
When using rotation-resistant rope, the exception in 1926.1414(c)(4)(ii)(A) applies instead of the standard text cited in 1926.1433(b)(4). This means you must follow the specified provision in 1926.1414(c)(4)(ii)(A) for boom hoist mechanisms when rotation-resistant rope is used.
These cranes must meet prototype testing requirements by complying with either Test Option A or Test Option B as described in 1926.1433(c).
Test Option A requires that all tests listed in SAE J1063 (Nov. 1993) Table 1 be performed to load all critical structural elements to their limits and that all strength margins in SAE J1063 Table 2 be met for cantilevered booms. See 1926.1433(c)(1)(i).
Test Option A requires that all tests listed in SAE J987 (Jun. 2003) Table 1 be performed to load all critical structural elements to their limits and that all strength margins in SAE J987 Table 2 be met for pendant-supported lattice booms. See 1926.1433(c)(1)(ii).
Test Option B requires that the testing and verification requirements of BS EN 13000:2004 be met. See 1926.1433(c)(2).
Computer modeling can replace physical testing only if the analysis methodology's reliability has been demonstrated by a documented history of verification through strain gauge measuring or strain gauge measuring combined with other physical testing; otherwise, the physical testing requirements under SAE J1063 and SAE J987 must be met. See 1926.1433(c)(2)(iii).
Tower cranes manufactured on or after November 8, 2010 must meet the prototype testing requirements in BS EN 14439:2006. See 1926.1433(c)(1).
The cab must have a complete range of the manufacturer's equipment rated capacities at all manufacturer-approved operating radii, boom angles, work areas, boom lengths and configurations, and jib lengths and angles (or offset). See 1926.1433(d)(1)(i).
The cab must include a work area chart for the capacities listed in the load chart and must clearly indicate areas where no load is to be handled. See 1926.1433(d)(1)(ii) and 1926.1433(d)(1)(iii).
The cab must show the recommended reeving for the hoist lines, recommended parts of hoist reeving, and the size and type of wire rope for various equipment loads, as well as the recommended boom hoist reeving diagram and rope specifications where applicable. See 1926.1433(d)(1)(iv), 1926.1433(d)(1)(v), and 1926.1433(d)(1)(vi).
The cab must list tire pressure (where applicable) and must include caution or warnings about equipment limitations and operating procedures, including the least stable direction. See 1926.1433(d)(1)(vii) and 1926.1433(d)(1)(viii).
Hooks without latches, or with latches removed or disabled, may be used only when a qualified person has determined it is safer to hoist and place the load without latches and the load routes are pre-planned so no employee works in the fall zone except those necessary for hooking/unhooking. See 1926.1433(d)(4)(ii) and 1926.1433(d)(4)(ii)(A).
Load hooks (latched or unlatched), ball assemblies, and load blocks must be heavy enough to overhaul the line from the highest hook position for applicable boom/jib lengths and parts of line in use, and hook/ball assemblies and load blocks must be marked with their rated capacity and weight. See 1926.1433(d)(2) and 1926.1433(d)(3).
Posted warnings required by this subpart and those supplied by the manufacturer must be kept legible, and an accessible fire extinguisher must be on the equipment. See 1926.1433(d)(5) and 1926.1433(d)(6).
Cab windows must be provided in front and on both sides of the operator, forward visibility must allow the operator to view the boom point at all times, windows may have removable/openable sections that can be secured, and windows must be safety glass or similar material that does not distort vision. See 1926.1433(d)(7)(iii)(A), 1926.1433(d)(7)(iii)(B), and 1926.1433(d)(7)(iii)(C).
Areas of the cab roof that serve as a workstation for rigging, maintenance, or other equipment-related tasks must support 250 pounds without permanent distortion. See 1926.1433(d)(7)(v).
Moving parts like belts, gears, pulleys, and other rotating components must be guarded where employee contact is possible during normal duties (except for maintenance/repair employees); exhaust pipes and similar components must be insulated or guarded where contact is possible; hydraulic and pneumatic lines must be protected from damage where feasible; and exhaust fumes must be discharged away from the cab. See 1926.1433(d)(8), 1926.1433(d)(9), 1926.1433(d)(10), and 1926.1433(d)(11).
Friction mechanisms (brakes and clutches) that control boom hoist or load line hoist must be sized with sufficient thermal capacity to control all rated loads using minimum recommended reeving and must be adjustable to compensate for lining wear to maintain proper operation. See 1926.1433(d)(12)(i) and 1926.1433(d)(12)(ii).
Hydraulic drums must have an integrally mounted holding device or internal static brake to prevent load hoist movement if hydraulic failure occurs, and employers meet their obligations under paragraphs (a)–(c) and (d)(7)–(13) if the equipment hasn't changed (except per 1926.1434) and the employer can refer to manufacturer documentation showing compliance. See 1926.1433(d)(13) and 1926.1433(e).
