  • Remote work. When you're out in the field, it pays to have a reliable power system to ensure your operation continues without a hitch. We offer mobile power solutions to keep your operation running smoothly.
  • Standby power. Downtime means lost income for business owners everywhere, no matter your industry. Be prepared for power outages with a gas or diesel genset from Hawthorne Cat.
  • Night work. Many operations, such as construction, industrial, marine, and oil and gas, require night work. You'll need power for light towers, power tools, and more in order to stay safe and keep moving.
