Grove TLL Load Chart Notes

Question 1

Find Gross load 360 degrees

Answer 1

object being lifted and deductions are added together for total

Question 2

when the radius is unknown

Answer 2

Boom angle is used to determine Gross Capacity

Question 3

If boom angle doesn’t correspond to an angle in the chart

Answer 3

go to next lowest boom angle in the chart and use that capacity

Question 4

Is it a good idea to check the capacity for the boom angle below and boom angle above and always use the lowest capacity

Answer 4

yes

Question 5

If the line pull is less than chart capacity

Answer 5

use the line pull value as gross capacity and make deductions from there

Question 6

If line capacity is gross capacity

Answer 6

no deduction of parts of line

Question 7

How many parts of line should you deduct

Answer 7

only what is not needed

Question 8

If given boom angle does not correspond to an angle in the chart

Answer 8

go to next lowest boom angle

Question 9

Line pull is less than chart capacity

Answer 9

so line pull must be used as gross capacity

Question 10

where gross capacity is determined by line capacity

Answer 10

there will not be an extra line deduction

Question 11

Auxiliary boom head is only rated for

Answer 11

single line lifts

Question 12

If boom angle is not listed in the chart

Answer 12

look at boom angle greater and lower than boom angle given, used smallest chart capacity

Question 13

If radius is not listed specifically in the chart on the range diagram

Answer 13

use next highest radius

Question 14

If corresponding tip height is between two numbers

Answer 14

use the highest number

Question 15

When picking off the extension

Answer 15

do not deduct the weight of the extension when it is being used in the pick

Question 16

when boom angle and radius falls between a tip height

Answer 16

use the greater distance

Question 17

Test question that has hints, of (no block, no ball, 0 boom angle)

Answer 17

tells us that this is not a conventional load chart problem

Question 18

when radius is unknown, gross capacity is determined by using boom angle, also if angle does not correspond to angle in the chart

Answer 18

go to next lowest boom angle and use the capacity

Question 19

If foot radius is not listed in the chart

Answer 19

use next longest radius

Question 20

boom length and radius are both between chart values

Answer 20

go to next longest boom length and next longest radius

Question 21

For main boom lengths less than fully extended

Answer 21

the rated loads are determined by boom angle
