Can a crane or telehandler lift the house's wall panels, and does anything but weight and wind limit it?

research/house-panellift

Can a crane or telehandler lift the house's wall panels? Weights of the eight house-offsite panels (343–559 lb open, 376–877 lb closed), best pick points and top-plate bending (4–12% of allowable with two picks): bending never limits the layout, weight and wind do. Hand-lifting needs 7–18 people; a 20 ft open panel swings 10° at about 12 mph. Stylised, every density and coefficient assumed.

What it found

Takes the eight wall panels of house-offsite and finds their weight (343–559 lb open, 376–877 lb closed; 3,753 and 5,031 lb for the shell), the best two pick points on each, and the top-plate bending at a 1.5 impact factor: 4–12% of the allowable stress, and plate bending alone would allow a solid panel of 60 ft with two picks (28 ft with one). Bending never limits the layout; the lift is a weight and wind problem. At the NIOSH 51 lb limit a panel needs 7–18 people, so hand-lifting is out, and a 20 ft open panel hung broad face to the wind swings 10° at about 12 mph (15 mph closed). Stylised: densities, glazing weight, impact and drag are assumed, the lift is a rigid-body estimate, and the sheathing is ignored.
