Lifting of Plate Heat Exchanger

[Muhammad Ijaz]

Dear Sir,

Problem:
A plate heat exchanger (PHE) is placed at middle platform of multistory steel structure. The platform over PHE platform can not be removed.

Solution
I want to lift PHE by using upper platform. Sketch is attached. Angle shown in sketch shall be more than 45 deg.

Concern
Is this lifting OK? Or may cause some deformation/damage to plates of PHE?
Any other solution for lifting if damage may happen?

Sketch ?

What did the vendor of the PHE say when you contacted them ?

Can you post an outline drawing of the PHE showing weights and CG ???

Again, there is no sketch ....

You seem to have lost interest in this question

Most PHEs have holes at the tops of the endplates specifically for 4-point lifting ....

As an alternative, you could remove the piping connections, jack the HX up a couple of inches and use four rollers to remove the HX

The rollers (HILLMAN ROLLERS) could run in a steel channel or on top of a flat plate ... (You supply us no details, of course)

You could also, with the same budget, make the troublesome platform above the HX removable and also ask the responsible structural why he would do such a thing. IMHO, ALL GRATING IN A MODERN PROCESS FACILITY SHOULD BE MOVABLE..

Looking forward to your response ....... But you seem to have lost any interest in this thread ....
