Understanding Safe Operating Temperatures and Battery Maintenance for DC Vacuum Lifters

Understanding Safe Operating Temperatures and Battery Maintenance for DC Vacuum Lifters

 

At Great Lakes Lifting, ensuring the safety and efficiency of your equipment is our top priority. To help you make the most of your Wood’s Powr-Grip (WPG) vacuum lifters, we’re highlighting key insights from Service Bulletin 2011-01, which provides guidance on safe operating temperatures and battery maintenance for DC vacuum lifters.

Operating Temperatures

Vacuum lifters are designed to operate reliably within specific temperature ranges. The recommended minimum temperature for operating a DC-powered vacuum lifter is 32°F (0°C). Operating below this threshold introduces risks, particularly with moisture freezing within the system.

Here’s what you need to know:

• Moisture Risks: Freezing temperatures can cause water in the vacuum system to turn to ice. This ice may block airflow, interfere with seals, or even damage components due to expansion.
• Prevention Tips:
  • Always ensure that air filters are free of water accumulation.
  • Confirm that the load is completely dry and free of frost or ice.

By following these precautions, you can minimize the risks associated with freezing temperatures.

Battery Maintenance

Battery charge levels significantly impact the performance of your vacuum lifter, especially in colder conditions. Here are the essentials for battery care:

• Cold Weather Challenges: Lead-acid batteries lose efficiency in cold temperatures, providing less current to start the vacuum pump.
• Minimum Requirements: A 50% charge (approximately 12.2 volts) at 32°F (0°C) is the baseline for reliable pump operation. However, colder conditions require a higher charge level to ensure performance.
• Best Practices:
  • Keep batteries warm, ideally around 70°F (21°C), before use.
  • Fully charge the battery prior to operation.
  • Be mindful that cold weather reduces battery longevity, requiring more frequent recharging or replacement.

Improving Safety and Performance

Wood’s Powr-Grip continuously enhances its products to improve safety and reliability. By adhering to these guidelines, you can ensure the safe operation of your vacuum lifters, even in challenging environments.
