Transformers | Understanding Power Needs for Lifting Decks

Lifting Deck Transformer

Why do lifting deck trailers need a stable 24V power supply?

Lifting deck trailers require a stable 24V power supply to operate efficiently and reliably. Power can be sourced from the tractor unit via an Anderson coupling, independent trailer batteries, or a bay-based supply — each with its own merits and considerations.

Available Power Supply Options

  1. Anderson coupling from the tractor unit – Draws power directly from the tractor while connected.
  2. On-trailer independent batteries – Offers flexibility but requires ongoing maintenance and can be prone to failure if neglected.
  3. Bay power – A fixed supply available at designated loading bays, offering dependable, consistent energy.

Understanding the Role of Transformers

Bay power typically provides 415V 32A 3-phase AC electricity. However, lifting deck systems require 24V DC at around 300A. A transformer is used to convert the AC input to a suitable DC output.

Advantages of Bay-Sourced Power

  • Reliable Output: Ensures consistent power without relying on the trailer’s batteries.
  • Lower Risk: Avoids common issues with flat or poorly maintained batteries.
  • Operational Flexibility: Allows trailers to be left at a bay and operated independently.

Drawbacks of Using Transformers

  • Size & Weight: The required transformers are bulky and heavy.
  • Cost: Initial investment can be significant, especially for operators setting up multiple bays.
