Types of Construction Machinery
The construction machinery produced by our company mainly include the following types:
2-Axis Detachable Hydraulic Gooseneck Lowbed Semi-Trailer
2-axle hydraulic gooseneck lowbed trailer, front-mounted design with detachable gooseneck; equipped with FUWA axles, WABCO brand ABS braking system, and a combined floor consisting of chequered plate and wooden planks.
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:
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.
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.
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.
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.

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
