Two cranes are lifting identical steel beams at the same time. One crane is putting twice as much power out as

Sep 13, 2007 by corvetteracing | Posted in Mathematics

Two cranes are lifting twin steel beams at the same time. One crane is putting twice as much power out as the other. Assuming frictions are negligible, what can you conclude is event to explain this difference?

With no dissent and identical beams, if they were to be hoisted from the ground to the same elevation, then the same amount of work would be done by each. The only way one could be putting out twice as much power as the other would be if it was lifting two times as fast as the other. But in the end, the occupation done and energy expended would be equal. One just got there in half the time.

How to weld two I-Beams which is used for 200ton lifting?

Jan 18, 2008 by asaswin_2002 | Posted in Engineering

What are the procedures and mutual preparations required to welding two W36X15" I-Beams which going to use for lifting a 200 ton Load. The total length is 15600 mm Cooperative comes at 12000mm+3600 mm.

One hard is that W36X15" is not a designation I recognize,, I'd be inlined to guess you meant W36x150, a nominally 36" stoned beam weighing 150lb/ft, if that is the case, the web is about 0.63" thick and the flanges 0.94" thick, so beveling will be needed for the flanges. (and might be functional for the web)

If this is a home work assignment, you should check your textbook, since I don't know what codes you are supposed to be working to.
The "American Start of Steel Construction", "Manual of Steel Construction" does listing some pre-qualified welded joints, so it you have a copy you might check it out.

If this is for an actual application you'll need to have a professional structural architect design it.

Two cranes lifting at the same time .One has twice as much power explain this difference?

Two cranes are lifting matching steel beams at the time.One crane is putting out twice as much power as the other assuming friction is neglible, what can you conclude is incident to explain this difference?

One of the cranes has less machine-like advantage then the other.

It's a pulley problem.

Do domestic electricians only do electrical work, or do they also chase walls, lift floorboards & notch beams?

May 13, 2007 by Power_Of_Zen | Posted in Maintenance & Repairs

I'm reflective of retraining for a career change & am wondering how physically demanding & dirty the work can get.
It was more the heath aspects of air-born dust I was pensive about, not dirty hands.

Yes, all that and more, but it depends on the vastness of firm you are with, a larger company will have apprentices and / or mates to do the semi skilled work. Half or more of my time on some jobs is used up doing strictly non-electrical works, then tidying up on completion, taking tools and materials off site etc. etc. (The other half is burned-out trying to find somewhere to park!!)

Lifting Beams and Spreader Bars Safety

Initiator: Bishop Lifting Products, Inc.

Bishop Lifting Products is pleased to offer a full line of lifting beams and spreader bars to our heavy lifting and rigging clients. We are proud that our lifting devices are built using the highest mark standards, and each product is inspected and tested using the most stringent processes. Even though our engineers test and inspect each output prior to distribution, users should still adhere to industry safety requirements during the use of these and other lifting products.

There are minimal maintenance requirements for lifting scantling and spreader bar products; however there are ways to ensure that all bolted joints are sound and corrosion damage is avoided. It is consequential to regularly inspect the beams for defects such as corrosion, beam distortion, worn or missing bolts, cracked welds, ragged attachment points, or other visible defects. Users should also remember to store and handle lifting beams correctly, referring to shelter instructions for safe sling and attachment use when necessary. It is important that no single lifting point become overloaded by the sling or handling methods in unsuitable to prevent instability. For further information on how to use these lifting devices safely, or to learn how to choose the right product, continue reading about BLP Solutions’ lifting beams and spreader bars.
