When considering the purchase, relocation, or renovation of a mobile home, understanding the weight of its frame is crucial. The frame, often referred to as the chassis or undercarriage, serves as the structural foundation upon which the entire home is built.
Its weight influences transportation logistics, foundation requirements, and overall structural integrity. This article delves into the specifics of mobile home frames, exploring their types, weight variations, influencing factors, and considerations for selection.
What Is a Mobile Home Frame?
A mobile home frame is the skeletal structure that supports the manufactured home. It is designed to bear the weight of the home and its contents during transportation and while stationary. The frame typically consists of steel I-beams or C-channels, providing strength and durability. The design ensures that the home remains level and stable, both during transit and once placed on its foundation.
Key Components of a Mobile Home Frame:
- Main Beams: These are the primary load-bearing elements, usually made of steel, running the length of the home.
- Cross Members: Perpendicular supports that connect the main beams, distributing weight evenly across the frame.
- Axles and Wheels: Attached to the frame, these components facilitate transportation. They allow the home to be moved from the factory to its intended location.
- Tongue or Kingpin: The front part of the frame that connects to the towing vehicle, enabling the mobile home to be towed.
