The four-column building loading crane is a vertical material transportation equipment designed for self-built houses in rural areas, multi-story decoration and other scenarios. Its core advantages are a stable structure, strong load-bearing capacity, and the ability to "slide" materials directly into the floor.

Here's how it works,

Core composition and working principle

This kind of crane uses four columns (usually round tubes or angle steel) to support the top beam to form a stable portal frame.

· How it works: Use an electric hoist or winch to lift bricks, cement, sand and other materials vertically along the beam. · "Straight sliding" convenience: the boom can rotate to deliver materials directly to the room, so workers do not need to lean out the window to pick them up.
