Diesel generator hire for sites that cannot stop
Our generator hire range is for construction sites, shutdown work, event backup, and remote projects where mains power is not available or not reliable. Diesel sets are the usual choice because they handle long run times, take heavy starting loads better than small petrol units, and can be refuelled on site without much fuss.
We supply generators for short jobs, weekly hire and long-term projects. If you are running mixers, welders, hoists, pumps, lighting towers or office cabins, we will match the unit to your actual load instead of guessing. That helps avoid nuisance tripping, poor voltage and wasted fuel.
Sizes and power options from small backup to heavy site duty
Generator sizes are selected by output, phase and the type of machine you are feeding. For smaller temporary power needs, compact units suit tools, ticket booths, security points and low-load offices. For building sites and civil work, medium units are common for site cabins, small plant and mixed loads. Larger sets support cranes, batching support, dewatering systems and multiple distribution boards.
- Single-phase and three-phase options
- Manual or automatic start configurations
- Open set or silenced canopy options
- Portable towable units and skid-mounted sets
- Short-term, monthly and long-term hire
We can also assist with plant swop-outs if your existing unit is underperforming or down for service. In most cases, a correctly sized generator is cheaper to run than an oversized one idling all day.
Where generator hire works best on South African projects
Generator hire suits sites where power cuts, load-shedding, municipal delays or remote access would otherwise hold the job back. In Gauteng, generators are used on housing developments, shopfitting, roadworks and warehouse builds. In coastal areas like Durban and Cape Town, contractors also like the backup protection for moisture-sensitive equipment and security systems.
They are useful when you need a power source before the permanent supply is connected, or where the utility connection is not yet approved. We also support farms, substations, clinics, water projects and emergency response work. If your project changes every week, hire gives you flexibility without owning dead stock.
- New construction and site offices
- Emergency backup during outages
- Remote worksites with no grid connection
- Shutdowns, maintenance and testing
- Temporary power for pumps, compressors and lighting
Setup, cabling and fuel planning matter as much as the set
A generator must be installed correctly or it will not perform properly. That means checking cable length, correct earthing, load balance and where the exhaust will discharge. On busy sites we also look at access for refuelling, noise control and safe placement away from pedestrian routes. In some municipal areas you may need to keep noise within local by-laws after hours, so silenced units are often the better pick.
For larger jobs, we help plan the fuel system and daily run time so you are not caught short on a Friday afternoon. If your site uses a lot of starting current, such as compressors or pumps, we will factor that in before dispatch. Poor planning can cause voltage dips, and that is where problems start.
- Cable sizing and distribution board advice
- Earthing and safety checks
- Fuel use planning for daily and overnight run times
- Placement for access, ventilation and noise control
- Support for operator supply where needed
Care and servicing keep the power steady
Our fleet is maintained by our workshop team and checked before dispatch, then again during longer hire periods where required. Filters, oil, belts, batteries and general condition are monitored so the unit stays reliable through the hire. On dusty sites or in coastal humidity, that attention matters because heat and contamination can shorten service life fast.
If a breakdown does happen, we respond with practical support, including on-site servicing and replacement where needed. We know a dead generator can stop a whole crew, so speed is important. Our depots in Germiston, Midrand, Pretoria East, Boksburg, Durban, Pinetown, Cape Town and Bellville help us keep transport times reasonable. Weekend support is available for active sites too.
What to confirm before you place a generator order
To get the right machine first time, have your load details ready. That includes the equipment you want to run, whether it is single-phase or three-phase, your start-up surge and how many hours per day you need power. If you are unsure, send through the list and we will work it out with you, rather than sending a unit thats too small or too hungry on fuel.
It also helps to confirm site access, delivery hours, and whether you need long-term hire, off-hire collection, or a swap if your project moves. For Gauteng sites we can often dispatch quickly from Germiston and the surrounding depots, while our Durban and Cape Town branches support coastal and out-of-town work.
