Introduction

These 10 questions are for you to use to help get ready for the Load Chart & Rigging part of the CraneSafe Certification assessment for Folding Boom Truck Crane – 11 Tonnes & Under.

The questions on your assessment will be different from these but will be presented in the same format as these questions.

Following the questions are the load charts and rigging tables and then the answers. The answers explain how we arrived at the correct answer and you can use this to help work through any questions you may have gotten incorrect. We have not included all of the charts for this crane–but everything you need to answer the questions is included. You do not need the crane manual or full load chart package to answer the questions.

2. Answer: 2,300 lbs

Deductions from Gross Capacity Pallet forks 860 lbs Rotator 80 lbsTotal Deductions 940 lbs

The gross capacity at a radius of 45 ft and a height of 35 ft is 3,240 lbs.

The Net Capacity is 3,240 – 940 = 2,300 lbs

3. Answer: 25 feet

Load weight 6,000 lbs

Rigging 350 lbs

Total Load 6,350 lbs

At a height of 35 ft, the maximum radius a load of 6,350 lbs can be placed is 25 ft.



Certification



Part 2: Hiab 175

4. Answer: 890 kg

The gross capacity at a 12m radius and a 8m height is 890 kg.

5. Answer: 880 kg

Deductions from Gross Capacity

Pallet forks weight 420kg

At a height of minus 4m and a radius of 10m, the gross capacity is 1,300 kg.

The Net Capacity is 1,300 – 420 = 880 kg

6. Answer: 4 metres

The maximum radius for a Gross Capacity of 3,000 kg at a height of 7m is 4m.

Part 3: Effer 145.00 5S

7. Answer: 2,450 lbs

Deductions from Gross Capacity

Rigging 125 lbs

Gross Capacity at a radius of 26 ft is 2,575 lbs.

8. Answer: 14 feet 10 inches

Load weight 3,600 lbs

Rigging 50 lbs

Total Load 3,650 lbs

The maximum radius the load can be placed is 14’10”.

Part 4: Rigging

9. Answer: 3”

The capacity of a 3 inch nylon web sling at an angle of 45 degrees is 4,665 lbs.

4,665 x 2 = 9,330 lbs

The capacity of a 2 inch nylon web sling at an angle of 45 degrees is 3,110 lbs.

3,110 x 2 = 6,220 lbs (too small).

10. Answer: 9/16 inch 20 feet

The capacity of 9/16 inch wire rope slings in a 2-leg bridle configuration at a 60 degree angle is 9,900 lbs.

a) Since both legs of the 2-Leg bridle are the same length (20 feet), the angles must be the same, i.e. 60 degrees.

b) There are 180 degrees in a triangle, so the third angle (at the top) is 180 – 60 – 60 = 60 degrees.

c) A triangle with 3 equal angles must also have 3 equal sides. Therefore, the distance between the attachments is 20 feet. ?
