Excavator lift plan example: lowering a manhole ring into a manhole box
A 3D view from an RMT Solutions excavator lift plan (example job). A Cat 320 GC with the bucket off lifts a 1,760 kg chamber ring from the quick hitch lifting eye at 6.0 m radius and lowers it into a supported excavation, at 42.6% utilisation of the Caterpillar lift capacity chart.
The video is rendered from the same 3D model as the plan's elevation, exclusion zone plan and rigging drawing, so the machine, the radius and the rigging match the figures on the sheets.
The lift in figures
- Excavator
- Cat 320 GC, bucket off, lifting from the quick hitch eye
- Load
- 1,760 kg concrete chamber ring
- Gross load
- 2,065 kg including the quick hitch and 3-leg chain
- Duty
- 4,850 kg on the Caterpillar lift capacity chart at 6.0 m radius
- Utilisation
- 42.6%
- Set-down
- Into a manhole box with edge protection, inside the exclusion zone
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.
