3 Axle Hydraulic Gooseneck Lowbed Semi-Trailer

The 3 axle hydraulic goose neck lowbed semi-trailer is a specialized transport vehicle designed for carrying overweight, oversized, ultra-wide, or non-disassembled large cargo. It is widely used in fields such as construction machinery, wind power equipment, large vehicles, and industrial equipment.

 
 
 

High Strenth 4 Axle 80 Tons Lowbed Semi Trailer

Low Bed Trailer is commonly used to transport heavy-duty vehicles (such as tractors, buses, special vehicles, etc.), rail vehicles, mining machinery, forestry machinery, and construction machinery (such as excavators, bulldozers, loaders, pavers, cranes, etc.) and other heavy-duty cargoes.

 

 

Benefits of Construction Machinery

 

High Strenth 4 Axle 80 Tons Lowbed Semi Trailer

High strenth 4 axle 80 tons lowbed semi trailer have many advantages, including: 

 
01
 

Stability:

Lowboy trailers have a low center of gravity because of their low-lying deck. This lower stance gives them better stability when moving large or heavy cargo than other types of trailers. They also have a strong frame and axles supporting a heavy load.

 
02
 

Safety:

Lowboy trailers can haul large, heavy loads that would be unsafe for other trailer varieties. Loading and unloading a lowboy trailer is relatively easy and safe. Lowboy trailers are capable of towing heavy, tall equipment and machinery. A two-axle lowboy can haul up to 40,000 pounds, but this number can increase with the addition of more axles, reaching weights as high as 80,000 pounds.

 
03
 

Versatility:

Besides carrying tall loads, they can also haul over-width loads. Construction equipment and other industrial machinery are often extremely wide — too wide for other types of trailers. Lowboy trailers are designed to handle these wider loads and loads of unique shapes and sizes as long as the load falls within its carrying capacity.

 
04
 

Compliance:

Many areas have particular laws transporters must follow regarding what loads are legal for the road. Lowboy trailers help transportation companies, businesses, and private parties ship large loads while staying compliant with regulations. This is especially true when transporting tall equipment or specialized vehicles, such as construction vehicles and machines. Compared to other types of semi-trailers such as flatbeds and drop decks, lowboy trailers offer a significantly low deck height, allowing it to carry tall cargo while remaining compliant with height limits, both on highways and in urban areas.

2-axis Detachable Hydraulic Gooseneck Lowbed Semi-trailer

 

Structure of Construction Machinery

The structure of a two-axle detachable hydraulic gooseneck lowboy semi-trailer mainly includes the following components:

Gooseneck

The gooseneck is the front part of the lowboy trailer that attaches to the tractor. It typically features a hydraulic mechanism that allows it to be raised or lowered for easier loading and unloading.

01

Main deck

The main deck of a lowboy trailer is the flat surface where the cargo is placed. It is lower to the ground compared to other trailers, making it suitable for hauling tall and heavy loads.

02

Drop decks

Lowboy trailers often feature drop decks, which are sections of the deck that are lower than the main deck. These drop decks provide additional clearance for transporting oversized equipment.

03

Rear deck

The rear deck of a lowboy trailer is the section located behind the wheels. It provides space for securing the cargo and may also feature ramps for loading and unloading.

04

Wheels and axles

Lowboy trailers are equipped with multiple axles and wheels to distribute the weight of the cargo evenly and ensure stability during transport.

05

FAQ

Q: How much clearance is needed between truck bed and gooseneck?

A: The following tips will help you remain safe while on the road and will prevent you from denting the sides of the tailgate of your truck. Aim for minimum clearance. You need at least six inches of gooseneck trailer clearance as this is the requirement to handle most highway and off-road conditions.

Q: How to maintain your heavy duty low bed trailer?

A: 1. Before the new lowbed semi trailer is used for the first time, we should check it according to the “instructions for use” and tighten all external bolts and nuts.
2. Within the first 300 kilometers of a new drop deck trailer, its components are in a running state. During this period, the weight of the trailer should not exceed 80% of the rated load, and it should not be driven on muddy roads.
3. After the new low loader trailer runs for 30-50 kilometers, check the wheels and suspension bearings for high heat or noise. If you find any abnormality, find out the cause in time and remove it.
4. After the new low bed trailer travels 300-500 kilometers, you should tighten all bolts and nuts.

Q: How much weight can a lowboy hold?

A: A two-axle lowboy trailer can support a maximum weight of 40,000 pounds. However, the weight capacity can be increased up to 80,000 pounds by adding additional axles. The length of a lowboy well ranges from 24 to 29.6 feet. A 25' well is perfect for hauling most equipment, such as bulldozers.
