Lifting method for skid-mounted structures
Thread Content
A jacking block, 3 meters wide and several meters long, with I-beams all along its bottom – how is lifting usually carried out in such cases? Lifting lugs are welded to the top or sides of the I-beam, or other lifting methods are used. I earnestly ask all the experts for their guidance! I will definitely make up the score if there is a reply.
Personally, I believe that welding lifting lugs directly onto the I-beam will result in more even stress distribution, making the entire equipment more stable; thus, the outcome will be better. The original poster can analyze it on their own
Thank you for your reply. We have taken the load into consideration and feel that this welding method might not be sufficient; therefore, we plan to insert a pipe across the bottom of the I-beam as a main beam for lifting, which should be more reliable.
Depending on the load, it should be fine to have a larger welding area for the hook
Lifting lugs are welded to the I-beam at the bottom of the pry block, and lifting is carried out using a balance beam.
I’ve taken a look at your COG; it seems that this lift block of yours doesn’t have a top section – it has only one layer. It resembles the programmable valve lift block from PSA, and such lift blocks need to be designed with lifting lugs from the start. Then, lift the lifting frame.
What is the weight of the lifting blocks? What size of structure do you want to use? And how long is it, in terms of meters?
The lifting lugs need to be calculated based on the load
