25
On roller bearing type cranes where would the bearings be incased ?
Between the upper and lower sections
26
What keeps the upper works centred on the roller path ?
King pin
27
What provides the boom a secure and firm method of connecting to the upperworks
The boom foot pins and lugs
28
What do the counterweights provide ?
Stability
29
What provides a base for the upper works to revolve on (crawler)
Car body
30
The swing gear is fastened to the car body being engaged to the _____ it provides the upper a method of work
Swing pinion
31
What are the two things the track frames provide
A means of support to distribute the bearing weights | A means of moving the crane
32
What does the idler roller do ?
Acts as a guide for the proper functionality of the track assembly as well as a means of adjusting tension on the track
33
What transfers the weight of the crane and load to the track pads ?
The track rollers
34
What is mounted onto the end of the drive shaft and moves the drive chain
The inner drive sprocket
35
The drive chain engages what
The outer drive sprocket
36
The outer drive sprocket attaches to the ______ via a shaft
Drive tumbler
37
What has replaced most chain driven systems ?
Hydrostatic drives
38
What are the advantages of a hydrostatic drive
Reduces moving parts | Increase efficiency
39
What is the most dangerous part of running a lattice boom crane
Assembling the lattice
40
What must be used for "on outrigger" charts to apply ?
All outriggers
41
I'd you have all outriggers engaged but a tire is touching the ground can you use your outrigger charts
No
42
The outrigger cylinder must be connected and pinned to what ?
The outrigger float
43
What would you use to distribute the load weight on an outrigger
Blocking
44
What are three stipulations of blocking to be used under floats
Fairly rigid Tightly spaced At least 3 times larger in area than the float
45
Can your blocking be slightly un level
No. The collar could fail or the cylinder could be damaged/fail
46
If on soft ground can you block under the outrigger beams
No
47
What is the formula to find out how pressure is coming from one outrigger
P=F/A Pressure = Force/Area
48
Can you use the hoist line to level your crane
Yes but you will need to check at least over the rear and over the side
49
Can you use a carpenters level to level the crane
Yes as long as it is on a machined area on the upperworks
50
When installs a jib it must be prevented from swinging uncontrollably. What would you use
A tag line
51
How do you know which way your lacing on lattice sections will run
In the same pattern from top to bottom
52
Can you use any audio or hand signal you want ?
Yes only if it discussed and agreed upon by everyone involved with the lift before hand
53
Who needs to contact and identify each other on the radio directly before a lift
The operator and signaller
54
All directions shall be given to he operator from what perspective
The operators perspective
55
Each series of voice signals shall contain three elements. List them in order
Function, direction Distance and or speed Function stop
