PASS
For supporting the boom and working attachments at recommended travel and transit positions
and boom lengths the design factor for boom pendants or standing ropes shall not be less than:
3
For supporting rated loads the design factor for rotation resistant rope shall be:
5 or greater
What crane movement does the far left control in the operator's cab create?
Swing
All jibs on conventional type crane booms must have positive stops to prevent their movement
of more than
5 degrees above the straight line of the jib and boom
Booms stop limit
Angle of boom at highest postion
If telescoping boom sections are not equally extended what could possibly happen:
Possible failure of the longest section
To verify that the boom angle indicator is reading properly you should:
use a level
When using wire rope clips to make wire rope slings you should remember to:
1|Page
, never use wire rope clips to make a sling
On wheel mounted cranes, braking shall be provided to bring the machine to a stop on level
ground within a distance of 32' from a speed of:
15mph
In a two crane lift the center of gravity should be
Closer to the crane with the greatest capacity
For rubber-tired cranes working on rubber, the part of the load chart governed by stability is
based on what % of the crane's capacity?
75%
As a general rue on tandem crane lifts neither crane should be loaded greater than what % of
net capacity
75%
On long boom cranes, what is the major effect of abruptly stopping a rapid swing?
Action may overturn the crane or collapse the boom
The most important thing to remember when performing dual crane lifts is:
The cranes should not be loaded beyond 75% of their rated capacity
The total weight of a loaded personnel platform and related rigging shall not exceed what % of
the rated capacity for the radius and configuration of a crane or derrick
50%
Pre-operational inspections are necessary and required:
Enhance cranes safety by discovering discrepancies prior to operating.
If a crane has to be level to within 1% of grade, the maximum allowable variation in grade in a
horizontal distance of 20' would be:
2.4''
On a standard running rope, how many broken wires are cause for considering replacement?
3 broken wires in one strand in one lay
On a standing rope, how many wires need to be broken at an end connections before replacing?
