Rigging is divided into two classes, standing, which supports the mast (and bowsprit), and running, which controls the orientation of the sails and their degree of reefing. Configurations differ for each type of rigging, between fore-and-aft rigged vessels and square-rigged vessels.
How many types of rigging are there?
There are two broad categories of shackles, anchor and chain, but both of these categories can also include different types of shackles: screw pin, safety, and round pin types.
What are examples of rigging equipment?
Rigging equipment is diverse and specialized for the load being moved and the environment needed to move the object. Some examples include wire rope slings, webbing slings, chain slings, metal mesh slings, spread beams, and various rigging hardware.
What is basic rigging?
Introduction: This training course was developed to provide maintenance employees (Artisans) with no formal Rigger qualification, with adequate knowledge and skills to execute the required Rigging Operations safely, according to pre-set standards, to lift loads to a maximum weight of 5 Ton.

What are rigging hardware?
Rigging hardware is the equipment used to secure, lift, and suspend loads. Rigging itself is the chains, ropes, and cables that tie items down or lift them.
Why is rigging used?
Rigging is most common in animated characters for games and movies. This technique simplifies the animation process and improves production efficiency. Once rigged with skeletal bones, any 3D object can be controlled and distorted as needed.
What is lifting and rigging?
Rigging is both a noun, the equipment, and verb, the action of designing and installing the equipment, in the preparation to move objects. A team of riggers design and install the lifting or rolling equipment needed to raise, roll, slide or lift objects such as with a crane, hoist or block and tackle.
What are the four types of hitches in rigging?

- Sling passes through one end around the load, while the other end is placed on the hook. Load control is limited with only one sling rigged in a choker hitch.
- VERTICAL HITCH:
- BASKET HITCH:
- Sling-To-Load Angle:
What is negative rigging?
When butt-hitching or blocking wood (which also is known as negative rigging), the anchor point of the rigging is below the rigged piece. If the piece has to be stopped quickly or “snubbed off ,” shock loading occurs, and the forces that are generated can be very great.
What is positive rigging?
Positive/Overhead Rigging – rigging point is above the piece, used whenever possible. i. Negative Rigging – rigging point is below the piece, used in the absence of other options, always involves shock loading.
What is a Level 2 rigger?
A Rigger Level II can estimate load weight and center of gravity; identify lift points; determine and select rigging based on loading; perform pre-use inspection of rigging and lift points; identify and attach rigging with knowledge of hitch configurations and load angle factors, rigging capacities, and load integrity;
What is a Level 3 rigger?
A Rigger Level III is a rigger that can successfully demonstrate or have the knowledge of how to inspect rigging before use, identify and attach rigging with basic knowledge of hitch configurations, recognize associated hazards, signal operations, and use various types of rigging equipment and basic hitches and their
How do you calculate rigging?
One method uses a sling angle factor chart, the other, the ratio of the length of the sling divided by the height. The sling leg load of two vertical slings is one half of the total load for each sling. If the load weight is 1,000 lbs, the sling load for two vertical slings is: (1,000 lbs / 2) = 500 lbs for each sling.
What is the difference between hoisting and rigging?
As verbs the difference between rig and hoist
is that rig is to fit out with a harness or other equipment while hoist is to raise; to lift; to elevate; especially, to raise or lift to a desired elevation, by means of tackle or pulley, as a sail, a flag, a heavy package or weight.
