(7) “Base-mounted drum hoist” means a self-contained lifting unit which has a motor, a drum to receive the lifting cable, and mounting flanges for anchoring.
(8) "Blocking,” also referred to as ‘‘cribbing,” means wood or other material used to support equipment or a component and distribute loads to the ground. Blocking is typically used to support lattice boom sections during assembly/disassembly and under outrigger and stabilizer floats.
(9) "Boatswain’s chair" means a single-point adjustable suspension scaffold consisting of a seat or sling, which may be incorporated into a full body harness, designed to support 1 employee in a sitting position.
(10) "Bogie" means ‘‘travel bogie,’’ as defined in R 408.41005a(60).
(11) "Boom" when used on equipment other than a tower crane, means an inclined spar, strut, or other long structural member which supports the upper hoisting tackle on a crane or derrick. Typically, the length and vertical angle of the boom can be varied to achieve increased height or height and reach when lifting loads. Booms may be grouped into general categories of hydraulically extendible, cantilevered type, latticed section, cable supported type or articulating type.
(12) "Boom” or principle horizontal structure, when used on a tower crane, means if it is moveable up and down. If the ‘‘boom’’ is fixed, it is referred to as a jib.
(13) "Boom angle indicator" means a device which measures the angle of the boom relative to horizontal.
(14) "Boom hoist limiting device" includes boom hoist disengaging device, boom hoist shut-off, boom hoist disconnect, boom hoist hydraulic relief, boom hoist kick-outs, automatic boom stop device, or derricking limiter. This type of device disengages boom hoist power when the boom reaches a predetermined operating angle. It also sets brakes or closes valves to prevent the boom from lowering after power is disengaged.
(15) "Boom length indicator" indicates the length of the permanent part of the boom or the length of the boom with extensions/attachments.
(16) “Boom stop” means a device that is used to limit the angle of the boom at the highest recommended position.

(30) “Crawler excavator” means a device which consists of a rotating superstructure that has a power plant, operating machinery, and a boom, and which is mounted on a base, and which is equipped with crawler treads for travel. The function of the excavator is to dig, lift, lower, and swing loads at various radii.
(31) "Crossover points" means locations on a wire rope which is spooled on a drum where 1 layer of rope climbs up on and crosses over the previous layer. This takes place at each flange of the drum as the rope is spooled onto the drum, reaches the flange, and begins to wrap back in the opposite direction.
(32) "Dedicated channel" means a line of communication assigned by the employer who controls the communication system to only 1 signal person and a crane/derrick or to a coordinated group of cranes/derricks, signal person or persons.
(33) "Dedicated pile-driver" means a machine that is designed to function exclusively as a pile-driver. These machines typically have the ability to both hoist the material that will be pile-driven and to pile- drive that material.
(34) "Dedicated spotter" means an employee who meets the requirements for signal person qualifications and whose sole responsibility is to watch the separation between the power line and the equipment, load line and load including rigging and lifting accessories, and ensure through communication with the operator that the applicable minimum approach distance is not breached.
(35) “Derrick” means powered equipment consisting of a mast or equivalent member that is held at or near the end by guys or braces, with or without a boom, and its hoisting mechanism. The mast or equivalent member, or the load, or both are moved by the hoisting mechanism, which is typically base- mounted, and operating ropes. Derricks include A-frame, basket, breast, Chicago boom, gin pole, except gin poles used for erection of communication towers, guy, shearleg, stiffleg, and variations of such equipment.
(36) "Directly under the load" means when any part of an employee is directly beneath the load.

Assembly or Disassembly:
Sample Procedures for Minimizing the Risk of Unintended Dangerous Boom Movement
1. R 408.41015a(2)(f)(i) provides that when pins, or similar devices, are being removed, employees shall not be under the boom, jib, or other components, except where the requirements of 408.41015a(2)(f)(ii) are met. The exception in 408.41015a(2)(f)(ii) shall apply when the employer demonstrates that site constraints require one or more employees to be under the boom, jib, or other components when pins, or similar devices, are being removed. In this situation, the A/D director shall implement procedures that minimize the risk of unintended dangerous movement and minimize the duration and extent of exposure under the boom.
The following scenario is an example of how the exception applies. A boom cannot be disassembled on the ground because of above ground piping, as might be found in an oil refinery, that precludes lowering the boom to the ground. The boom shall be disassembled in the air, and the employees who remove the pins shall perform that work from an aerial lift with a base that is positioned on one side, the near side, of the boom. To gain access to the pins on the far side, the aerial lift basket shall move under the boom, since, due to lack of room, the aerial lift cannot be repositioned on the far side.
To minimize the risk of unintended dangerous movement while the pins are removed, the A/D director shall use an assist crane that is rigged to support the boom section that is being detached, using particular care to ensure that the section end that is near the employee or employees removing the pins is well supported. The duration and extent of exposure shall be minimized by removing the far side pins first, moving the aerial lift basket as soon as possible to the near side so that the employees are no longer under the boom, and then removing the near side pins.
2. R 408.41015a(2)(h)(vi)(A) provides that, during assembly or disassembly, the center of gravity of the load shall be identified if that is necessary for the method used for maintaining stability. R 408.41015a(2)(h)(vi)(B) states that, where there is insufficient information to accurately identify the center of gravity, measures designed to prevent unintended dangerous movement resulting from an inaccurate identification of the center of gravity shall be used.
An example of the application of R 408.41015a(2)(h)(vi)(B) is as follows. The boom shall be assembled by lowering boom sections sequentially into place using an assist crane. The A/D director’s plan shall keep the boom sections stable while they are lowered into place by attaching the assist crane hoist line above the center of gravity of each section. However, in assembling the non-symmetrical top section of the boom, the A/D director is not able to determine where to attach the assist crane hoist line so that it is above the center of gravity. In this situation, before raising the section, all personnel shall be kept clear of the section and the section shall be first raised a few inches to determine whether it tips when raised. If the section did tip, it would indicate it is not rigged over the center of gravity. If this occurs, the hoist line shall be repositioned and the procedure repeated, with employees kept clear of the section while it is raised, until the A/D director determines that it is rigged over the center of gravity and can be moved into place without dangerous movement.
