KNIGHT 55T TRIDEM DOUBLE DROP MECHANICAL GOOSENECK

Centerline 55T Hydraulic Detachable Neck Lowboy

The Centerline 55T Hydraulic Detachable Gooseneck trailer is an attractive option for operators who need a front loading trailer and don’t want to spend a lot of time detaching and attaching the gooseneck. The hydraulic detachable gooseneck is both quicker and safer to remove over a mechanical detachable gooseneck, particularly on rough, uneven, or wet terrain.
