Why Contractors Choose CAT307E?

1. Compact Size, Big Capability

The CAT 307.5 strikes a perfect balance between size and power. With an operating weight of 7,504–8,113 kg (16,543–17,886 lb) and a tail swing radius of just 1,995 mm (78.5 in), it navigates tight spaces—like urban backyards, narrow construction alleys, or indoor renovation sites—with ease. Yet, its robust digging force (37.8 kN bucket force, 54.6 kN stick force) and 4,047 mm (13.3 ft) maximum digging depth let it handle heavy tasks, from trenching and foundation work to loading material. This versatility eliminates the need for larger, less maneuverable machines on confined sites

2. Fuel Efficiency & Lower Operating Costs

Powered by the Cat C2.4 turbocharged engine (34.9 kW/46.8 hp), the 307.5 delivers strong performance while prioritizing fuel economy. Its efficient combustion and load-sensing hydraulic system reduce fuel consumption, cutting daily operating costs—critical for contractors managing tight budgets. Additionally, extended maintenance intervals (e.g., oil changes, filter replacements) minimize downtime and service expenses, keeping the machine productive longer

3. Durability for Tough Conditions

CAT’s reputation for ruggedness shines in the 307.5. It features high-strength steel in the boom, stick, and undercarriage, along with reinforced components that withstand abrasive materials (rock, gravel) and frequent use. The heavy-duty track system and sealed electronics protect against debris and moisture, making it reliable in rain, mud, or dusty environments. For contractors working in harsh conditions, this durability translates to fewer breakdowns and longer machine lifespans—maximizing return on investment

CAT 307E FAQ: Expert Answers to Top Contractor Questions

Q:Is the 307E suitable for lifting/loading? Max capacity?
