How Ermin Plant Hire Is Putting the Trelawny VoltMax Range to Work
If you work in surface preparation hire, you’ll likely know the common problems. Voltage drops on long cable runs, transformers need sourcing before the job starts and circuits often can’t handle the load. The Trelawny VoltMax range removes the variables and provides the output contractors want from corded equipment.
Ermin Plant Hire has invested in battery-powered surface preparation equipment, specifically the Trelawny VoltMax range, and the machines have been in heavy use since their introduction.
For Trelawny and DURO, the strong uptake of the Trelawny VoltMax range demonstrates that customers increasingly value the freedom to work wherever the job takes them, without compromising on performance.
Trelawny VoltMax battery-powered surface preparation
Supplied through DURO, Trelawny’s specialist hire sector distribution partner, Ermin’s fleet now includes:
- TCG250 Concrete Grinder – grinds, levels and profiles concrete surfaces. Removes hard concrete up to 4mm deep. Integrated dust extraction is included as standard and no transformer is needed on site.
- TFP200 Floor Scarifier – profiles and prepares floor surfaces for new finishes. Suited to coating removal and surface texturing ahead of application work.
- TFS230 Floor Stripper – strips adhesives, coatings and floor coverings. Built for sustained output on heavy-use hire work.
All three pieces of battery-powered surface preparation equipment run on the Cramer 82V battery platform.
What cordless removes from the job
The practical problems site power creates are routine on construction and refurbishment projects, and the Trelawny VoltMax battery-powered surface preparation equipment removes them.
With these machines, set-up is faster, work continues without interruption and they can be used wherever the job takes you – without needing to sort out site power first.
How battery-powered surface preparation equipment performs under load
Contractor Luke Thomas who hired the TCG250 on multiple occasions and used both the battery and 110V versions directly shared that:
“We were really surprised with the power and ability to remove hard concrete up to 4mm. The convenience of not having to pull leads around site was extremely helpful, and the dust extraction worked well. Having used both the battery and 110V versions, I would say they both perform very well, but the convenience of the cordless machine makes it my preferred option.”
The Cramer battery platform advantage
Ermin already operates gardening and landscaping equipment on Cramer 82V batteries, allowing the Trelawny VoltMax machines to use the same batteries and chargers already in service. The batteries and chargers can be used on both ranges, increasing battery use throughout the fleet and making better use of existing charging infrastructure.
For hire businesses managing large asset pools, that cross-compatibility reduces the number of battery and charger systems to stock, maintain and train staff on. As more manufacturers adopt the Cramer 82V platform, it becomes easier to standardise on a single battery system across different types of equipment.
Mark Davis, Ermin’s Director of Operations also commented that:
“As demand for battery-powered equipment continues to grow, we felt the Trelawny VoltMax range was a natural addition to our fleet. We already had positive experience with Trelawny’s 110V surface preparation equipment, so introducing the cordless versions was a straightforward decision.The feedback from customers has been extremely encouraging, particularly around the convenience of eliminating transformers and trailing cables while still delivering the performance they expect.The compatibility with the Cramer battery platform was another key factor for us, as it aligns with other battery-powered equipment already operating within our fleet. Utilisation has been strong from day one and we’re seeing increasing interest from customers who are actively looking for more flexible, battery-powered solutions.”
Ermin is planning further investment in the Trelawny VoltMax battery-powered surface preparation equipment range in the coming months.
