4 Axle Drop Deck Gooseneck Trailer

The gooseneck of the 4-Axle Drop Deck Gooseneck Trailer, serving as the trailer's core connection and load-bearing component, features a floor-standing design. When connected to the tractor, it can be adjusted in height via hydraulic or mechanical means to accommodate different tractor types and avoid instability caused by mismatched connection heights.

Description

introduction

The 4 Axle Drop Deck Gooseneck Trailer is a heavy-duty semi-trailer with lowered deck and detachable or fixed gooseneck. It is designed for transporting oversized machinery, construction equipment, and industrial components.

features

Four heavy-duty axles distribute up to 80–120 tons of payload, reducing axle load concentration and improving legal road compliance in multiple markets.
The drop deck structure lowers cargo height by 500–900 mm compared with standard flatbeds, allowing taller equipment to be transported within highway clearance limits.
High-strength Q460/Q550 steel main beams provide excellent bending and torsional resistance, ensuring long service life under repeated heavy loading.
Gooseneck design transfers part of the load directly to the tractor fifth wheel, enhancing towing stability and reducing frame stress.
Mechanical or hydraulic ramps enable self-loading of excavators, bulldozers, and cranes, minimizing dependence on external lifting equipment.
WABCO braking system with ABS/EBS options delivers reliable stopping performance, meeting international safety standards.
Shot blasting plus epoxy primer and polyurethane topcoat provide long-term corrosion protection, especially for humid and coastal environments.
Customizable axle brands, deck dimensions, and load ratings support OEM/ODM requirements, enabling adaptation to local regulations and customer preferences.
