This is actually a very common piece of equipment in our industry. It allows users to reach up under structures with roof height restrictions to still perform the lift to extract the load.
Something like the attached. Basically a heavy I-beam structure with counter weight on one end and the suspended load on the other end. Ultimately the goal would be to be able to live adjust the location of the counter weight for quicker multi lift scenarios. But this is the general idea
Does anyone have any good reference material for design of a cantilever lifting system used by a crane? Wanting to start digging into this for our company. Eventually would want to add some ease-of-use features for in field adjustment, but I'm just curious about more basics of it right now
Greenalleycat - ideally, load case would always be centered and equally distributed. It would be up to our department, in conjunction with the client, to ensure correct measures are taken to ensure as close to evenly distributed loading as possible. I initially called them spanner beams because...
Your note about making the side-by-side beams act as one member is accurate - that is my goal. I've found many resources regarding beam designs, but none clearly define how to go about making them act as one. I'm trying to do this without any analysis software at my disposal, and so I figured I...
Hello all - new here but looking to learn! We are looking at a scenario where we are wanting to use beams, with internal gussets and welded seams as load spanners. I'm curious how to properly set up calculations to see what maximum allowable loads would be. There are a few different sizes of...
