How can girder transport vehicles be operated safely in rainy weather?
What precautions should be taken when operating beam-transport vehicles in the rain? On rainy days, drivers’ visibility is impaired and the braking performance of beam-transport trucks deteriorates, resulting in longer stopping distances. Therefore, highway drivers in rainy conditions must maintain a controlled speed and keep a safe following distance; generally, driving speed on rainy days should be reduced by at least about 20% compared with clear-day conditions. It is strictly forbidden to abruptly step on the accelerator or slam on the brakes, as this can lead to vehicle drift or skidding.

Precautions for Tire-Type Girder Transporters
The tire-type girder transporter consists of two independently operating units: the front unit and the rear unit. The front unit is passive, while the rear unit is active; each is equipped with its own independent power system that offers multiple gear settings, allowing the transporter to select an appropriate speed during operation based on road conditions.

What are the features of the 300-ton girder transporter?
The 300-ton girder transporter, also known as the “five-bridge vehicle,” is the preferred choice for high-quality, large-scale bridge projects. It breaks the industry norm of limited load capacity—typically around 200 tons—and is a heavy-duty vehicle featuring ultra-high power, substantial payload capacity, strong grade-climbing ability, excellent stability and resistance to overturning, and adaptability to a wide range of road conditions. So what are its key features? Let’s take a closer look.

How can crane equipment be operated efficiently?
As the degree of mechanization in lifting operations continues to increase, the widespread adoption of girder-transporting launchers has not only accelerated construction schedules but also enhanced construction quality. However, because lifting equipment is subject to various factors during daily operation, its performance may fail to be fully realized. What precautions should we take during routine construction to ensure that the equipment operates at its optimal performance?

Method for Cleaning the Hydraulic System Drain Circuit of a Girder Transporter
During cleaning of the girder transporter, tapping with a wooden mallet can accelerate the detachment of contaminants. Particular attention should be paid to tapping the bent and welded sections of the pipeline, but excessive force must be avoided to prevent deformation or rupture of the pipe.

Safety Precautions for Highway Beam-Transporting Vehicle Operations
Highway girder transporters are widely used in construction. Specifically designed for the transportation of precast girders for highway bridges, these machines can perform even better with diligent daily maintenance.

Winter Maintenance for Beam Transport Vehicles
Winter weather is cold, with large diurnal temperature variations and frequent icy and snowy conditions. Such weather often causes vehicles to fail to start and accelerates the aging of components on high-speed railway beam-transport vehicles. At the same time, vehicle safety is also relatively reduced.

Structural Composition of the Girder Transport Vehicle
The girder transporter consists of a power system, transmission system, gearbox, drive system, braking system, steering system, main frame, and turntable.

Advantages of Intelligent Unmanned Cranes
The intelligent unmanned crane leverages industrial networking technologies to collect data from the crane’s electrical control system, enabling real-time monitoring of its operational status. Through remote services and remote monitoring, the crane can be operated remotely, ensuring that lifting operations are carried out safely and efficiently.

Safety Measures for Girder Transport Vehicles
The girder transporter is a specialized vehicle used to convey precast reinforced concrete bridge girders—fabricated either at the precasting plant or at the bridge site—to the bridge-erection machine. It comes in rail-mounted and tire-mounted configurations, among others. The vehicle primarily consists of dozens of driving and idler wheels, a chassis, a cab, a control system, and auxiliary equipment. Due to its heavy payload capacity (up to 1,000 tonnes), it is designed with a low profile to minimize the overall height of the bridge-erection machine. It serves as ancillary equipment for bridge-erection operations.
