From May 15th to 18th, 2025, the 4th Changsha International Construction Equipment Exhibition grandly kicked off at the Changsha International Convention and Exhibition Center.

This industry event, which gathered 1,806 enterprises from around the world, covered an exhibition area of 300,000 square meters, and attracted over 350,000 professional visitors, has become a top platform for showcasing cutting-edge technologies and innovative achievements in the construction machinery field.

Among numerous eye-catching exhibits, the Caterpillar 307 amphibious excavator, with its outstanding performance and advanced technology, immediately became the spotlight as soon as it was presented.

I. The Focus of the Exhibition Booth: Caterpillar’s Star Exhibit

Caterpillar’s exhibition booth was highly recognizable at the exhibition site. The grand booth design and the orderly arrangement of equipment demonstrated the demeanor of a global construction machinery giant. As the core product of this exhibition, the 307 amphibious excavator, with its unique appearance and powerful presence, drew the attention of a large number of professional visitors, industry media, and potential partners. During the exhibition, visitors kept flocking to Caterpillar’s booth, stopping, observing, and communicating around the 307 amphibious excavator. The staff also patiently and meticulously provided professional explanations for each visitor, elaborating on the product’s various features and advantages in detail.

II. Outstanding Performance: The Hardcore Strength of the Caterpillar 307 Amphibious Excavator

(I) Powerful Power: The Foundation for Efficient Operation

The Caterpillar 307 amphibious excavator is equipped with an original high-performance engine, which has a strong and stable power output. In complex and variable working environments, whether dealing with thick and sticky sludge during river dredging or handling tough vegetation and rugged terrain in wetland projects, this engine can continuously and stably provide ample power to ensure the efficient operation of the equipment. Its excellent digging force performance enables it to quickly complete a series of operation processes such as digging, loading, and transporting. In actual engineering cases, compared with similar equipment, the daily operation volume of the 307 amphibious excavator in river widening projects has increased by 30%, significantly shortening the construction period and effectively reducing the overall construction cost.

(II) Innovative Design: Smooth Passage on Land and Water

The equipment is equipped with a uniquely designed pontoon undercarriage, which endows it with excellent amphibious passage performance. The combination of segmented oil pipes and a larger travel motor greatly enhances the equipment’s torque, allowing it to easily climb a 50-degree steep slope and move freely in complex environments such as shallow waters, swamps, and muddy riverbanks. The high-wear-resistant panel material ensures that the chassis is not easily deformed under long-term and high-intensity use. The 40CR material chain is not only sturdy and durable but also significantly extends
