Rolling And Flying Scenery

Question 1

What are wagons?

Answer 1

Wagons are small platforms that rest on castors instead of legs.

Question 2

What are 2 types of casters ?

How are they attached to platforms to become wagons?

Answer 2

1. Swivel
2. Rigid

They are bolted onto caster plates attached to the bottoms of the platform

Question 3

How much space should be left between the bottom of a wagon and the stage floor.

Answer 3

1/2 - 3/4 inch

Question 4

How far apart should each caster be placed and why?

Answer 4

No more than 48 inches

To prevent the platform from bouncing when it’s walked on

Question 5

What is a truss used for?

What materials can they be made of?

Answer 5

Used to bridge large spans of space between supporting points.

Wood, and welded steel

Question 6

Why are trusses so strong?

Answer 6

The distribution of forces; the downward force being channeled into horizontal force by the legs of the triangle

Question 7

What are the types 3 of trusses?

Answer 7

1. Sandwich truss
2. Plywood truss
3. 2x4 truss sandwich

Question 8

What are revolves/turntables?

What are the 2 primary challenges of building them?

Answer 8

Circular platforms that pivot on their central axis.

1. Attaching the casters so the wheels are perpendicular to the radii
2. Placing the pivot in exactly the centre of the revolve

Question 9

What is a skid?

Answer 9

A caster less substitute for wagons that is used to shift lightweight scenic elements like chairs, tables etc.

Question 10

What is a winch?

What is mechanical advantage?

Answer 10

A machine that converts rotational motion to linear movement by increasing power through mechanical advantage.

Mechanical advantage allows heavy loads to be moved w relatively little effort

Question 11

What does the amount of mechanical advantage depend on?

Answer 11

The comparing of the length of the crank handle with the radius of the winch drum.

Question 12

What is a motorized winch? And what are the 2 types found in theatres.

Answer 12

A variable speed electric motor .

1.DC MOTOR
2.AC MOTOR

Question 13

Rigging & flying

Answer 13

Suspending/hanging something in the air. Can be dynamic (it moves) or static (doesn’t move)

Question 14

Spotlines

Answer 14

An independent rope that can be placed wherever you want

Good for individual pieces of scenery

Question 15

Chain motor

Answer 15

At the stage level

Connects to a rope or cable from your grid or beans

Question 16

WLL

Answer 16

WLL: Working load limit

All rigging instruments have a WLL. Way less than actual breaking point

Question 17

Side rigging

Answer 17

Rigging on the wrong spot on a shackle (side of the shackle)

Question 18

Why fly scenery?

Answer 18

To reveal/conceal

for scene changing

Old style fly system (Hemp house)

Answer 19

Fly system: Where arbour is a Sunday tied around the wires/ropes

Sandbags tied to the end of the Sunday = counterweight systems

Question 20

Electronic/motorized winch fly systems

Answer 20

Most sophisticated fly system that has one winch per batten

Question 21

Double purchase weight system

Answer 21

Relies on pulley systems

Can be run from the fly floor, not only stage deck

Question 22

Mechanical advantage

Answer 22

Lift stuff at the half of the weight

Having more rope tied around pulley system

Question 23

Hardware

Answer 23

• Carribeener
• Shackles
• Quick link
  -illigitamable shackle
  -hanging irons (top, bottom)
• eye bolts
• cable keeper

Question 24

Brailing

Answer 24

Flying things (side to side instead of ups)

Question 25

Breasting

Answer 25

Flying things upstage and downstage

Question 26

Tripping

Answer 26

eg. attaching a line to a flown in a cyclorama so that it makes a U shape & it is out of the way.

Question 27

2 types of drops

Answer 27

Roll drops (don’t roll on pipe)
Olio (ropes wrap around pipe)
