ASME B30.2-2011 pdf – Overhead and Gantry Cranes (Top Running Bridge, Single or Multiple Girder, Top Running Trolley Hoist).
(b) Equipment shall be inspected at intervals dependent on the use of the equipment as follows:
(l) normal service — yearly
(2) heavy service — yearly
(3) severe service quarterly
(c) The inspection shall include the items [isted in para. 2-2.1.4(c) and the following items, as applicable:
(1) deformed, cracked, or corroded members.
(2) loose or missing fasteners, such as, but not urnited to, bolts, nuts, pins, or rivets.
(3) cracked or worn sheaves and drums.
(4) worn, cracked, or distorted parts such as pins, bearings, wheels, shafts, gears, rollers, locking and clamping devices, bumpers, and stops.
(5) hooks, in accordance with the provisions of
ASME B30.1O.
(6) excessive wear of brake system parts.
(7) excessive wear of drive chain sprockets and excessive drive chain stretch.
(8) deterioration of controllers, master switches, contacts, limit switches, and push-button stations, but not limited to these items.
(9) wind indicators for proper operation.
(10) gasoline, diesel, electric, or other power plants for proper operation.
(ii) motion limit devices that interrupt power or cause a warning to be activated for proper performance. Each motion shall be inched or operated at low speed into the limit device with no load on the crane.
(12) rope reeving for compliance with crane manufacturer ‘s design.
(13) function, instruction, and safety information signs, labels, or plates for legibility and replacement.
(14) rope and end connections in accordance with para. 2-2.2.3.
(d) Adjustments, repairs, or replacements shall be made, as necessary, in accordance with para. 2-4.2.4.
(e) Dated records shall be made of apparent external conditions found in para. 2-2.1.5(c) to provide a basis for a continuing evaluation and placed on file.
2-2.1.6 Inspection of Cranes Not in Regular Use
(a) A crane that has been idle for a period of I mo or more, but less than 1 yr, shall be inspected before being placed in service in accordance with the requirements listed in para. 2-2.1.4.
(b) A crane that has been idle for a period of 1 yr or more, shall be inspected before being placed in service in accordance with the requirements listed in para. 2-2.1.5.
2-2.2.1 GeneraL
All inspections shall be performed by a designated person. Any deficiencies identified shall be examined and a determination made by a qualified person as to whether they constitute a hazard and if a more detailed inspection is required.
2-2.2.2 Frequent Rope Inspection
(a) All ropes should be visually inspected at the start of each shift. These visual observations should be concerned with discovering gross damage, such as listed below, that may be a hazard.
(2) distortion of the rope, such as kinking, crushing, unstranding, birdcaging, main strand displacement, or core protrusion
(2) general corrosion
(3) broken or cut strands
(4) number, distribution, and type of visible broken wires [see paras. 2-4.3.1(b)(1) and (2) for further guidance]
(b) When damage as described in paras. 2-2.2.2(a)(1) through (a)(4) is discovered, the rope shall either be removed from service or given an inspection as detailed in para. 2-2.2.3(b).
2-2.2.3 Periodic Rope Inspection
(a) The inspection frequency shall be determined by a qualified person and shall he based on such factors as
(1) expected rope life as determined by experience on the particular installation or similar installations
(2) severity of environment
(3) percent of capacity lifts
(4) frequency rates of operation
(5) exposure to shock loads
Inspections need not be at equal calendar intervals and should be more frequent as the rope approaches the end of its useful life.
(b) This inspection shall cover the entire length of rope. The individual outer wires in the strands of the rope shall be visible to the person during the inspection. Any deterioration resulting in appreciable loss of original strength, such as described below, shall be noted and determination shall be made as to whether further use of the rope would constitute a hazard.
(1) points listed in para. 2-2.2.2(a).
(2) reduction of rope diameter below nominal diameter due to loss of core support, internal or external corrosion, or wear of outside wires. See para. 2-4.3.1 (b)(5).
(3) severely corroded or broken wires at end connections.
(4) severely corroded, cracked, bent, worn, or improperly applied end connections.
(c) Special care should be taken when inspecting sections of rapid deterioration, such as the following:
(1) sections in contact with saddles, equalizer sheaves, or other sheaves where rope travel is limited.
