2019 Caterpillar 307B

Proven performance meets Japanese engineering in this 2019 Caterpillar 307B mini excavator, currently located in Hangzhou, Zhejiang. With a 7-ton working capacity and robust 6,500 kg operating weight, this machine delivers reliable power through its Mitsubishi 4M40E1 engine—a 4-cylinder, 2.8L powerhouse generating 40.3 kw of rated output. Built as a joint venture/import model, it combines Caterpillar's legendary durability with precision manufacturing standards.

Operational specs demonstrate serious capability: maximum digging depth reaches 4,110 mm, while excavation height extends to 7,290 mm. The 6,200 mm excavation radius and 5,150 mm unloading height provide versatile reach for diverse jobsite demands. Equipped with a 1,670/2,210 mm rod length and 450 mm track plates, this workhorse maintains stability across challenging terrain.

Key advantages include:

• Compact 2,200 mm transport width with tight 1,750 mm rear turning radius
• Generous 135L fuel tank and 94L hydraulic reservoir for extended operation
• Traditional power configuration proven across thousands of jobsites
• Five years of proven field reliability since manufacture
