Floor notes
Power Windows
A practical floor note on power windows, supply checks, and machine loading before delivery to site.
Before any machine is switched on, the power details matter: voltage, phase, breaker size and the condition of the incoming supply.
Power Windows deals with the checks that stop a machine arriving to the wrong supply. On jobs around Johannesburg, Crown Mines and further out to Durban or Cape Town, that usually means confirming voltage, phase, breaker size and cable condition before loading.
Supply checks before machine dispatch
- Voltage and phase confirmed on site
- Incoming board photo with breakers visible
- Machine rating plate details sent through
- Site contact named for offloading day
Use this note with the machine listing, not on its own. The listing tells you the make-up of the machine and its power requirement, while Power Windows helps compare that requirement with the workshop supply. That is where many boring and grinding installations go wrong.
How Power Windows affect boring machines on the floor
Power Windows covers supply checks, machine loading and site readiness before delivery. It is for buyers who need to confirm that the incoming machine suits the available power and can be offloaded safely at the workshop.
Start with the incoming supply, then look at the machine load and the route into the workshop. A lathe or boring machine that suits the job can still stall a handover if the site has only single-phase power, weak breakers or poor cable runs. Buyers in Johannesburg, Durban and Cape Town often need these checks done before transport is booked.
Label the distribution board before anything is moved. Add the machine plate, plug or isolator, and the place where offloading will happen. Those details make it easier to spot a mismatch before the machine reaches site.
Checks recorded from this note
You leave with a short record of the supply, the machine load and any issue that needs attention before delivery. That may include phase confirmation, breaker size, cable length, lifting access or whether a static converter has been mentioned. The aim is to name the risk early, not after transport.
Use Power Windows with a machine listing and a workshop note before you change the site plan. Check the supply plate, plug arrangement and any loose accessories again before the truck leaves. Mention the machine make and the work you plan to run when asking about lathes, boring or valve grinding equipment.
- Supply matched to the intended machine
- Board and isolator photographed before loading
- Power query sent to the team
Workshop conditions across South Africa
Crown Mines jobs often need more than a quick look at the machine itself. Access for riggers, forklift position, door width, concrete condition and the state of the incoming power all matter when a heavier lathe or boring machine is being moved. Separate the electrical question from the production requirement so neither gets missed.
Coastal workshops may be dealing with corrosion in boards, plugs and switchgear. Inland sites often show dust build-up, older wiring and temporary extensions that are not suitable for machine testing. Load-shedding and generator changeover arrangements should also be checked before any demonstration run.

Power points buyers should confirm
A practical floor note on power windows, supply checks, and machine loading before delivery to site.
Keep this note with the machine paperwork while the inspection details are still fresh. It helps when a buyer needs to show what supply is available, what the machine requires, and what must be corrected before delivery to site.
