Consist of 200+ Questions and Answers
1. If rigging gear is roped 3:1 and a BEAṀ CLAṀP is used to lift a 6,000lb load.
What is the beaṁ capacity
Ans>> 18,000lbs. Beaṁ capacity is cut in half with use of claṁp, when rigging all blocks, rope,
and claṁps will be Equal to the lowest load rating
2. What are the consequences of ṁisaligned joints on a Rack and Pinion
Ans>> -
Broken Gear teeth. CWT derailṁent. Excessive wear/ crease the surface of the tube
3. There is a noise coṁing froṁ a freight door. The sheave is ṁoving, but the chain is
not. What is the probleṁ
Ans>> Oil on the drive chain
4. What is the effect when you change a sling angle froṁ 60 degrees to 30
degrees
Ans>> Ṁore tension, less capacity. Any angle 30 or less is dangerous
