Question 1

To stop a cable that is attached to anchoring hardware from wearing out too quickly, which of the following devices should be used?

Accepted Answer

Thimble

Answer

A thimble is a protective fitting used to prevent a rope or cable from wearing out too quickly where it forms a loop (eye) around anchoring hardware. It provides a smooth, rounded surface that prevents sharp bends and friction, which would otherwise abrade and weaken the cable over time. This extends the lifespan and maintains the strength of the cable.

Question 2

Which part of a tip-tied branch will come off the cut?

Accepted Answer

Butt end

Answer

When a branch is 'tip-tied,' the rigging line is attached near its tip. Upon making the cut, the heavier butt end of the branch, which is closer to the trunk, will be the part that comes off the cut first. The rigging system then controls the descent of this butt end, allowing for a controlled and safe removal.

Question 3

Which of these tools should be reserved for connectors that are rarely required to be opened?

Accepted Answer

Screw links

Answer

Screw links, also known as quick links, are best reserved for connectors that are rarely required to be opened. They provide a very strong and secure connection but typically require a wrench or tool to fully tighten and loosen. This makes them less convenient for frequent use compared to carabiners or shackles, which are designed for quicker attachment and detachment.

Question 4

If the pulley's diameter is three times larger than the rope's diameter, what would be the bend ratio of a block-based rigging system?

Accepted Answer

3:1

Answer

The bend ratio in a rigging system is calculated by dividing the diameter of the pulley (or block sheave) by the diameter of the rope. If the pulley's diameter is three times larger than the rope's diameter, the ratio is 3 divided by 1, resulting in a 3:1 bend ratio. A higher bend ratio is generally preferred as it reduces stress on the rope and extends its lifespan.

Question 5

The process of removing limbs or bringing down an entire tree with the use of ropes and other tools is called:

Accepted Answer

Rigging

Answer

Rigging is the specialized process in arboriculture that involves using ropes, blocks, pulleys, and other equipment to safely remove limbs or entire trees in a controlled manner. This technique is essential in confined spaces or near structures, allowing arborists to lower sections of a tree without causing damage to property below.
