BMP Tree Support Systems Vocab Flashcards
Amon-eye nut
A drop forged eye nut used to fashion a through-hardware anchor
Anchor
Hardware installed to affix and/or terminate a cable or guy to the tree, ground, or other device
Anchor tree
A tree used to provide a supplemental support in a guying installation
Arborist
A professional who possesses the technical competence l, through experience and related training, to provide for or supervise the management of trees and other woody plants in the residential, commercial, and public landscapes
Bond
An electrical connection between an electrically conductive object and a component of a lightning protection system that is intended to significantly reduce potential differences created by lightning currents
Braces
Metal rods installed through branches or stems to limit movement and provide supplemental support
Bracing
Installing of lag-threaded screws or threaded-steel rods in limbs, leaders, or trunks to provide the supplemental support to weak branch unions
Cable
(Verb) To install steel cable or synthetic rope between branches within a tree to limit movement and provide supplemental support
(Noun) steel wires twisted together in a uniform helical arrangement; cable intended for arboriculture applications typically contain seven wires that are zinc coated
(Noun) steel or fiber ropes installed between branches within a tree to limit movement and provide supplemental support
Cabling
Installing of a cable within a tree between limbs or leaders to limit movement and provide supplemental support
Codominant stems
Forked branches nearly the same size in diameter, arising from a common junction and lacking a normal branch union; may have included bark
Compartmentalization
A natural defense process in trees by which chemical and physical boundaries are created that act to limit the spread of disease and decay organisms
Connector Clamp
A multipurpose bolt clamp used to bond conductors or to bond a conductor to a ground terminal or tree supplemental support system, and meets the specifications of ANSI/UL - 96
Dead-end brace
A brace formed by threading a lag-threaded screw rod directly into a limb, leader, or trunk but not through the side opposite the installation
Dead-end grip
A manufactured wire wrap designed to form a termination in the end of a 1 x 7 left hand lay cable
Dead-end hardware
Anchors or braces that are threaded directly into the tree but not through the side opposite the installation; dead end hardware includes but is not limited to lag hooks, lag eyes, and lag threaded screw rods
Eye bolt
A drop forged, closed eye bolt used to anchor cables to the tree in a through-fastened system
Eye splice
A closed-eye termination formed from a common-grade cable by bending it back on itself and winding each wire around the cable a minimum of two complete turns
Grip
A mechanical device that grasps and holds a cable during installation
Guy
Wire, rope, or webbing installed from a tree to an external anchor to limit movement and provide supplemental support
Guying
Installing of a steel cable or synthetic-rope cabling system between a tree and an external anchor to provide supplemental support
Included Bark
Bark that becomes embedded in a union between branch and trunk or between codominant stems, causing a weak structure
Lag eye
A lag threaded, drop forged, closed eye anchor used for dead-end systems
Lag hook (J hook)
A lag threaded l, J shaped anchor
Lag thread
A coarse screw thread designed for securing into wood
Lag-threaded hardware
Anchor or brace with lag threads, lag-threaded hardware includes but is not limited to lag eyes, lag hooks, and lag threaded screw rods
Lag-threaded screw rod
A lag threaded steel rod used for dead end and through brace installation
Peen
The act of bending, rounding, or flattening the fastening end of a through-hardware for the purpose of preventing a nut from backing off
Props
Rigid structures installed beneath a low branch or trunk to limit movement and provide supplemental support
Qualified arborist
An individual who, by possession of a recognized degree, certification, or professional standing, or through related training and on the job experience is familiar with the equipment and hazards involved in arboriculture operations and who has demonstrated ability in the performance of the special techniques involved
Shall
As used in ANSI standards, denotes a mandatory requirement
Should
As used in ANSI standards, denotes an advisory recommendation
Swag Sleeve
A hollow metal fitting used to terminate a wire rope (aircraft cable)
Taut
Tightened to the point of eliminating visible slack
Termination
A device or configuration that secures the end of a cable to the anchor in a cabling or guying installation
Termination hardware
Hardware used to form a termination; termination hardware includes but is not limited to dead end grips, thimbles used in eye splices, sewage sleeves, and cable stop termination devices
Thimble
An oblong galvanized, or stainless steel fitting with flared margins and an open ended base
Threaded steel rod
A machine threaded steel rod used for through brace installations
Through-brace
A brace formed by installing through brace hardware into a limb, leader, or trunk, secured with bits and heavy duty washers; through hardware includes but is not limited to eye bolts, lag-threaded screw rods, and threaded steel rods
Turnbuckle
A drop forged closed eye device for adjusting cable tension
Wire rope
(e.g. aircraft cable) a cable fabricate from individual wires twisted together in a uniform helical arrangement; wire rope used in arboricultural applications typically containing seven groups of 19 wires each
Wire rope clamp
A clam consisting of a U-bolt l, bracing plate, and fastening nuts
