floating derrick: a mast or equivalent member held at the head by guys or braces, with or without a boom, for use with a hoisting mechanism and operating ropes, mounted on a barge or pontoon. The power plant may be installed below decks.
foot bt’arivig or block (sill block): the lower support on which the derrick mast rotates.
gantry (A-frame): a structural frame, extending above the superstructure, to which the boom support ropes are reeved.
gudgeon pin: a pin connecting the mast cap to a derrick mast allowing rotation of the mast,
guy, derrick: a rope used to steady or secure the mast or other member in the desired position.
hoist mechanism: a hoist drum and rope reeving system used for lifting and lowering loads.
hook. latch-type’: a type of hook with a mechanical device to close the throat opening of the hook.
jib: an extension attached to the boom point to provide added boom length for lifting specified loads. The jib may be in line with the boom or offset to various angles in the vertical plane of the boom.
land crane: a crane designed primarily for operation on land.
list: angle of inclination about longitudinal axis of barge or pontoon.
load, rated: the maximum allowable working load in pounds (kilograms) designated by the manufacturer in accordance with Section 8-1.1.
load, working: the external load in pounds (kilograms) applied to the crane or derrick, including the weight of load-attaching equipment, such as load blocks, shackles, and slings.
load block, lowtr: the assembly of hook or shackle, swivel, sheaves, pins, and frame suspended by the hoisting ropes.
load block, upper: the assembly of sheaves, pins, and frame suspended from the boom.
,riast (derrick): the upright member of the derrick used for support of the boom.
mast cap (spider): the fitting at the top of the derrick mast to which the guys are connected.
(7) rope reeving for compliance with crane or derrick manufacturer’s recommendations
(8) electrical apparatus for malfunctioning, signs of excessive deterioration, dirt, and moisture accumulation
(9) guys for tension, inspected daily, when used (guy derricks only)
(10) derrick mast fittings and connections for compliance with manufacturer’s recommendations
(11) hoist brakes, clutches, and operating levers for proper functioning before beginning operation — daily, when used
(h) Bar’ or Pontoos
(1) ballast compartments for proper ballast
(2) deckloads for proper securing
(3) chain lockers, storage, fuel compartments, and battening of hatches
(4) fire-fighting and lifesaving equipment in place and functional
(5) null void compartments sounded for leakage — inspected weekly
8-2.1.3 PeriodIc InSpection
Complete inspections shall be performed at intervals as generally defined in para. 8-2.1.1(b)(2), depending on the activity, severity of service, and environment, or as specifically indicated below. These inspections shall include the requirements of para. 8-2.1.2 and, in addition, items such as the following. Any deficiencies, such as listed, shall be examined and determination made as to whether they constitute a hazard. This inspection does not require dismantling unless external conditions indicate further examination is required.
(a) Cra,ws and Dcrricks
(1) structural members including boom for deformed, cracked, or corroded members
(2) bolts or rivets for tightness
(3) sheaves and drums for cracked or worn surfaces
(4) pins, bearings, shafts, gears, rollers, and locking devices for wear, cracks, and distortion
(5) brake and clutch system parts. linings, pawis, and ratchets for excessive wear
(6) load, boom angle, and other indicators, over their full range, for any significant inaccuracies
(7) gasoline, diesel, electric, or other power pbnts for proper performance or compliance with applicable safety requirements
(8) chain drive sprockets for excessive wear and chain for stretch.
