A few pics with the expandable track model: a Kubota U17 doing concrete breaking with a Arrowhead breaker. Yes: the nitrogen pressure is checked and the pins are greased often and have the tools to make pin and bushing changes with less agony than waiting till ugly - thus these wear parts get replaced long before the arm steel is obliged to move etc.
The U17 is in the four foot area between the building and the retaining wall with one track hanging over that cutaway strip. No wrong moves LOL. Machine's house couldnt move much cause the 'zero swing' becomes 'very reduced' when the tracks are set to narrow, therefore had to precisely swing the boom a little left and a little right with a very light foot on the pedal. And my helper usually eyeballs the setup continually to remind me for example to watch the boom by the window say ~ but he had the days off (for new grandbaby assist w family). By some luck: no touch no hits no errors!
Handy machine once again saves the back from holding the pavement breaker.
FYI On other projects: We have lowered this machine into holes, strapped it on the forks of a reachlift and extended it out over obstacles....and have seen similar antics on sites where the big iron is busy w production and the small machine is in a trench making life easier around a valve or tie in, or removing thrust block etc etc.
Indented portion is about the job: Concrete walk was placed in late summer 2022 but unfortunately the simple easy job didnt have very much time taken by either the owner/manager &/or the lead person of the concrete company to check FF of the building slab and think/evaluate the limitations & conditions with a sketch and some good notes.....until: rain came and water entered the apartment at the wall sill plate.
How'd that happen - wasnt obvious, but the walk was inadvertently placed above the FF by about three inches against the building....the expansion joint "tween area" filled with water and as it rose up, it went under the building wrap and was inside in the new carpet etc....attempts to seal the concrete to the stucco wall failed and the quick solution was to sawcut a strip next to the building and to daylight a new flowline low point. [That is the slot next to the building where the track is hanging over]

Lots of measuring planning thinking evaluating occurring now with the sad but only solution to remove the new walk - it is reported for mindful of the need to carefully check the jobs in the planning stages.
