Recent practical examples

New blue motor installed vertically on the high-level extractor beside an access platform

Silica-Sand Extractor Motor Replacement

A heavily corroded, high-level 16.5 kW motor needed replacing on a silica-sand dust extractor serving a processing and grading plant. With the correct mount unavailable within the job’s time frame, Harvtec produced a CNC laser-cut mounting plate to fit the new motor to the existing extractor.

Work described by Harvtec, supported by five supplied project photographs.

  • Problem: heavy corrosion on an exposed, high-level extractor motor; the correct replacement mount was unavailable in time.
  • Work: replacement of the 16.5 kW motor, a custom CNC laser-cut mounting plate and adaptation to the existing extractor.
  • Outcome: the replacement motor fitted to the existing extractor.
Refurbished blue hot air mover with its motor and repaired square-to-round transition

Hot Air Mover Refurbishment for a Steel Foundry

What started as a repair to a water-damaged fan casing became a wider refurbishment. Harvtec brought together site removal, workshop fabrication, motor and fan work, and inverter maintenance on a large hot air mover serving a steel foundry.

Work described by Harvtec, with supplied project images.

  • Problem: water damage, corrosion and holes in the casing and transition.
  • Work: removal, workshop repairs, motor refurbishment, new bearings and impeller, balance and concentricity checks, painting and inverter maintenance.
  • Record: photographs of removal, transport, stripped components and the refurbished assembly.
Clean replacement filter cartridges installed inside the silica-sand extractor

Filter replacement on a silica-sand extractor

Cartridge replacement on a 12-cartridge reverse-jet extractor, with photographs of the used cartridges, replacement component and fitted filters.

Real Harvtec work, supported by the supplied photographs and equipment description.

  • Equipment: a 12-cartridge reverse-jet silica-sand extractor.
  • Work: replacement of filter cartridges.
  • Record: before, replacement-component and fitted-cartridge photographs.
Industrial sander control panel during Harvtec fault investigation

Wide belt sander fault investigation

Harvtec investigated ongoing issues with an industrial wide belt sander, combining machinery knowledge, controls awareness and practical electrical fault finding.

Existing Harvtec work summary and accompanying work image. Customer details are withheld; no measured savings or completion date are claimed.

  • Problem: recurring equipment issues needed a practical diagnosis before further repair decisions.
  • Approach: inspect the machine, controls and supporting evidence instead of treating it as a single-trade fault.
  • Outcome: clearer next actions for repair, maintenance and future fault finding.
Plasma cutting work for a workshop repair

Plasma cutting and welding

Harvtec used practical cutting and welding support for repair and preparation work where a clean, hands-on workshop fix was needed.

Existing Harvtec work summary and accompanying work image. Customer details are withheld; no measured savings or completion date are claimed.

  • Problem: a repair or adaptation needed practical cutting and welding support.
  • Approach: prepare the material, cut cleanly, weld where needed and keep the job focused on the required outcome.
  • Outcome: useful workshop support for a hands-on repair without overcomplicating the job.
Function block programming for a Siemens LOGO 8 controller

Function block programming for Siemens LOGO 8

Harvtec Workshop can support small controls work, including function block programming where a simple controller needs clear logic and practical testing.

Existing Harvtec work summary and accompanying work image. Customer details are withheld; no measured savings or completion date are claimed.

  • Problem: a small machine or control process needs simple, understandable logic rather than a large control-system project.
  • Approach: map the required permissives, latches, outputs and operator behaviour before testing the program.
  • Outcome: a clearer small-control setup that can be checked, adjusted and explained later.
Zappi EV charger on Harvtec’s custom-built pedestal beside parking bays at an apartment building in Carbis Bay

EV charging at an apartment building in Carbis Bay

A bespoke pedestal and coordination with residents and the apartment building’s maintenance company helped a customer in Carbis Bay get an installation they had struggled to arrange.

Harvtec installation, described by the owner and shown in the accompanying work photograph.

  • Setting: a customer’s parking space at an apartment building in Carbis Bay.
  • Work: Harvtec designed and built the pedestal and coordinated the installation with residents and the maintenance company.
Zappi EV charger fitted to a rectangular stainless steel backplate beside a fence with glazed panels

A stainless steel backplate, designed to fit

A custom stainless steel backplate designed by Harvtec allowed the charger to be fitted at the existing fence and panels, with access arranged alongside the customer and neighbours.

Harvtec installation, described by the owner and shown in the accompanying work photograph.

  • Setting: a charging position at an existing fence and panels.
  • Work: bespoke backplate design and charger installation, with neighbour access coordinated.
