ASME B30.8 pdf download.Floating Cranes and Floating Derricks.
Within the general scope defined in Section I of the Introduction, ASME B30.8 applies to cranes and derricks mounted on barges or pontoons. Floating cranes are convertible for excavation service and other uses that are categorically not considered to be lilting service. The requirements of this Volume are applicable only to floating cranes and floating derricks used for vertical lifting and lowering of freely suspended unguided loads (see Figures 8-0.1-1 through 8-0.1-5).
SECTION 8-0.2: DEFINITIONS
accessory: a secondary part or assembly of parts that contributes to the overall function and usefulness of a machine.
administrative or regulatory authority: governmental agency or the employer in the absence of governmental urlsdiction.
anchorage: a point of attachment for tie-downs.
angle indicator, boom: an accessory that measures the angle of the boom to the horizontal,
auxiliaiy hoist: a secondary hoist rope system used either in conunctlon with, or Independently of, the main hoist system.
axis of rotation: the vertical axis around which the crane superstructure rotates.
billboard: a flat, usually inclined platform on which to stow spare or emergency anchors.
bitt (bollard): an upright wooden or metal post on a dock, barge, or pontoon to which hawsers may be secured.
boom: a member hinged to the superstructure and used for supporting the hoisting tackle.
boom angle: the angle above or below horizontal of the longitudinal axis of the base boom section.
boom harness: the block and sheave arrangement on the boom point to which the topping lift rope is reeved for raising and lowering the boom.
boom hoist mechanism: a means for supporting the boom and controlling the boom angle.
(b) Barge or Pontoon
(1) cleats, bitts. chocks, fenders, capstans, ladders. stanchions for corrosion, wear, deterioration, and deformation
(2) compartments for leakage and structural damage; void compartment atmosphere shall be tested before entering
(3) rescue skiff, lifelines, work vests, life preservers, and ring buoys for deterioration and seaworthiness
(4) four-corner draft readings
(5) flrefighting equipment for serviceability
8-2.1.4 Cranes or Derricks Not in ReguLar Use
(a) A crane or derrick that has been idle bra period of I month or more, but less than 6 months, shall be given an inspection conforming with the requirements of paras. 8-2.1.2 and 8-2.4.1 before being placed in service.
(b) A crane or derrick that has been idle for a period of over 6 months shall be given a complete inspection conforming with the requirements of paras. 8.2.1.2. 8-2.1.3, and 8-2.4.2 before being placed in service.
8-2.1.5 Inspection Records
Dated records shall be made on critical items such as brakes, hooks, and ropes. Records should be available,
8-2.1.6 OperationaL Aids
(a) Prior to daily operation, operational aids shall be checked in accordance with the device/crane manufacturer’s recommended procedures to determine if they are functioning properly.
(b) Operational aids shall be inspected and tested in accordance with the device/crane manufacturer’s recommended procedures as part of the periodic inspection of para. 8-2.1.3.
(c) When operational aids are inoperative or malfunctioning, the crane and/or device manufacturer’s recommendations for continued operation or shutdown of the crane shall be followed until the problems are corrected. Without such recommendations and any prohibition from the manufacturer against further operation, the requirements of para. 8.3.2.2(b) shall apply.
SECTION 8-2.2: TESTING
8-2.2.1 OperationaL Tests
(a) New or Reinstalled Floating Cranes or Derricks. Prior to initial use, all new or reinstalled floating cranes or derricks shall be tested with no hook load, under the direction of a qualified person to ensure compliance with this Volume, including but not limited to the following.
8-2.3.3 Adjustments and Repairs
(a) Any hazardous condition disclosed by the inspection requirements of Section 8-2.1 shall be corrected before operation is resumed. Adjustments and repairs shall be done only by designated personnel.
(b) Adjustments shall be maintained to ensure correct functioning of components. The following are examples:
(1) functional operating mechanisms
(2) operational aids
(3) control systems
(4) power plants
(5 yang lines
(6) brakes and clutches
(7) signal systems
(c) Repairs or replacements shall be provided as needed for operation. The following are examples:
(1) Criticalpartsoffunctionaloperating mechanisms that are cracked, bent, broken. corroded, or excessively worn shall be repaired or replaced.
(2) Critical parts of the structure that are cracked, bent, broken, or excessively corroded shall be repaired or replaced.
