Introduction

These 12 questions are for you to use to help get ready for the Load Chart & Rigging part of the CraneSafe Certification assessment for Friction Lattice Crane.

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.

CRANE RATING DATA

Load ratings are in pounds and do not exceed 75% of the load which would cause tipping with cranestanding level on firm uniformly supporting surface. Safe loads depend on ground conditions, boomlengths, radius of operation, and proper handling, all of which must be taken into consideration by user.

"Radius in feet" is the horizontal distance at crane base level from center of rotation to a vertical linethrough the center of gravity of the suspended load.

Lifting is approved only in those areas for which ratings are shown in the rating chart. Blocks, slings,buckets, and other load carrying devices are considered part of the load. Retractable A-frame must be infully raised position for all ratings. Ratings in bolded areas are limited by strength of material, or factorsother than stability.

Main load line is 1-1/8 inch diameter with a minimum breaking strength of 130,000 pounds. Boomsuspension line is 7/8 inch diameter with a minimum breaking strength of 113,200 pounds. Boomsuspension pendants are 1-3/8 inch diameter with a minimum breaking strength of 208,000 pounds.

Boom and jib erection is over the long end of the machine with idler tumblers blocked and with "Lift Rating"counterweight.

Model 9270 may be used for duty cycle service with a 60,000 pound counterweight. Maximum clamshellboom is 140 feet and maximum dragline or magnet boom is 100 feet. Maximum clamshell rating is 28,000pounds; maximum dragline rating is 27,000 pounds and maximum magnet rating is 24,000 pounds.

Designed and rated to comply with ANSI Code B30.5.

Jib ratings are based on the minimum boom length specified above. For ratings on shorter booms consult factory. The jib load rating is the lesser of:

(a) the maximum jib rating, or

(b) the main boom rating at the jib working radius, reduced by the effective jib wight and by the weight of all suspended load carrying devices.

The main boom rating with jib in place must be reduced by the effective jib weight, the weight of main fall blocks and slings, and twice the weight of jib tackle.

10. Answer: 1 inch

The capacity for a 1 inch, 2-leg bridle at a 30 degree angle is 17,950 pounds.The capacity for a 7/8 inch, 2-leg bridle hitch at a 30 degree angle is 13,750 lbs (too small).




11. Answer: 5/8 inch

The capacity of 5/8 inch, two-leg chain bridle is 14,480 lbs.

The capcity of a 1/2 inch, two-leg chain bridel is 9,600 lbs (too small).

The slings are choked so there is a 25% reduction in capacity.

14,480 x .75 = 10,860 lbs

12. Answer: 4 inch

The capacity of a 4 inch, 2-leg bridle hitch at a 60 degree angle is 7,620 pounds.

The capacity of a 3 inch, 2-leg bridle hitch at a 60 degree angle is 5,715 lbs.

When slings are choked, there is a 25% reduction in capacity.

7,620 x .75 = 5,715 pounds

5,715 x .75 = 4,286 pounds (too small)
