Steel erection lift plan example: a mobile crane erecting a steel frame
Part 2 of the steel delivery example: a 3D view from an RMT Solutions steel erection lift plan (example job). A Liebherr LTM 1090-4.2, working over the side, lifts a UB 406x178x60 on two load rings through its top flange from the telehandler’s staging point into the next bay of a steel frame in progress, at 17.3% utilisation of the Liebherr duty chart.
The video is rendered from the same 3D model as the plan's drawings, so the machine, the radius and the load match the figures on the sheets.
The lift in figures
- Crane
- Liebherr LTM 1090-4.2, working over the side, outriggers on mats
- Configuration
- 30.0 m main boom, 22.5 t counterweight
- Load
- UB 406x178x60, 7.0 m, 421 kg
- Rigging
- Two RUD VLBG-PLUS M20 load rings through the top flange at 200 mm centres, 2-leg chain with 3 m legs
- Gross load
- 760 kg including the rigging and the hook block
- Duty
- 4.4 t on the Liebherr chart at the 24 m landing radius
- Utilisation
- 17.3%
Utilisation is the gross load, including all the lifting accessories, divided by the capacity on the manufacturer's chart for that configuration and radius.

Example job for illustration. It is not a site instruction or an approved plan for another lift: every lift needs a plan for the actual machine, load and site.
