Construction machinery trailers: what matters about ramps and approach angle

A ramp that's too short or too steep is one of the most common problems in construction machinery transport – and it can be avoided at the trailer-buying stage if you check the right figures.

Why the approach angle matters

If the angle between the ramp and the ground is too steep, the machine's underside or boom will hit the ground before it reaches the deck. This applies especially to machines with low ground clearance or a long wheelbase.

How ramp length and loading height relate

The lower a trailer's loading height, the shallower the approach angle at the same ramp length. A construction machinery trailer like the ML 3500 with a continuous folding ramp is specifically designed for a shallow, practical approach angle.

Ramp width for the machine in question

Besides length, ramp width also needs to match your machine's track width. Check especially with tracked vehicles or particularly wide wheel loaders that the ramps offer enough clearance on both sides.

Ramp surface

A grippy, anti-slip ramp surface matters for safety in wet conditions or with dirty machine tyres. When buying, look for ribbed or textured ramp plate rather than a smooth surface.

Conclusion

Before buying a construction machinery trailer, check ramp length, width and surface against your machine's dimensions. That avoids unpleasant surprises the first time you load it.
