30
Q

The swing gear is fastened to the car body being engaged to the _____ it provides the upper a method of work

A

Swing pinion

31
Q

What are the two things the track frames provide

A

A means of support to distribute the bearing weights

A means of moving the crane

32
Q

What does the idler roller do ?

A

Acts as a guide for the proper functionality of the track assembly as well as a means of adjusting tension on the track

33
Q

What transfers the weight of the crane and load to the track pads ?

A

The track rollers

34
Q

What is mounted onto the end of the drive shaft and moves the drive chain

A

The inner drive sprocket

35
Q

The drive chain engages what

A

The outer drive sprocket

36
Q

The outer drive sprocket attaches to the ______ via a shaft

A

Drive tumbler

37
Q

What has replaced most chain driven systems ?

A

Hydrostatic drives

38
Q

What are the advantages of a hydrostatic drive

A

Reduces moving parts

Increase efficiency

39
Q

What is the most dangerous part of running a lattice boom crane

A

Assembling the lattice

40
Q

What must be used for “on outrigger” charts to apply ?

A

All outriggers

41
Q

I’d you have all outriggers engaged but a tire is touching the ground can you use your outrigger charts

A

No

42
Q

The outrigger cylinder must be connected and pinned to what ?

A

The outrigger float

43
Q

What would you use to distribute the load weight on an outrigger

A

Blocking

44
Q

What are three stipulations of blocking to be used under floats

A

Fairly rigid
Tightly spaced
At least 3 times larger in area than the float

45
Q

Can your blocking be slightly un level

A

No. The collar could fail or the cylinder could be damaged/fail

46
Q

If on soft ground can you block under the outrigger beams

A

No

47
Q

What is the formula to find out how pressure is coming from one outrigger

A

P=F/A

Pressure = Force/Area

48
Q

Can you use the hoist line to level your crane

A

Yes but you will need to check at least over the rear and over the side

49
Q

Can you use a carpenters level to level the crane

A

Yes as long as it is on a machined area on the upperworks

50
Q

When installs a jib it must be prevented from swinging uncontrollably. What would you use

A

A tag line

51
Q

How do you know which way your lacing on lattice sections will run

A

In the same pattern from top to bottom

Q

Can you use any audio or hand signal you want ?

A

Yes only if it discussed and agreed upon by everyone involved with the lift before hand
