Basic Specifications

• Model: CAT307E2, a 7 – ton – class small – hydraulic excavator.
• Manufacturer: Caterpillar, a well – known global manufacturer of construction machinery.
• Working Weight: Approximately 6,900 kg, which includes the standard stick, counterweight, steel tracks, bucket, operator, and a full tank of fuel.
• Engine Model: Cat C2.6 DI Turbo diesel engine, with a net power of 41.5 kW (55.7 hp) at 2000 rpm, meeting the China National III emission standard.

Performance Characteristics

• Power Performance: The Cat C2.6 DI Turbo engine provides strong power, ensuring that the excavator can complete various tasks such as digging, lifting, and loading efficiently. The standard/power dual – mode function allows for one – click switching between lower fuel consumption and higher productivity to adapt to different work requirements.
• Hydraulic System: It adopts a load – sensing hydraulic system with a variable – displacement piston pump, which can distribute flow on – demand, improving work efficiency. The system pressure is 28,000 kPa, and the pump flow at 2000 rpm is 147 L/min, providing sufficient hydraulic support for the excavator’s actions.
• Digging Performance: The standard bucket capacity is 0.33 m³, the maximum digging depth is 4,070 mm, the maximum digging height is 7,240 mm, and the maximum ground reach is 6,180 mm. These parameters enable it to handle various digging tasks in different working conditions.
• Travel and Rotation: The travel speed is 3.2 km/h at low speed and 5.1 km/h at high speed, and the maximum climbing ability is 30°. The machine’s rotation speed is 10.8 r/min, and the rotation torque is 16.3 kN·m, which is convenient for the machine to move and position on the construction site.

Cab and Operation

• ComfortCat: The cab is designed to be spacious and comfortable, with an air – suspension seat and a retractable seat belt, which can reduce the operator’s fatigue during long – term work. The color – display COMPASS monitor allows the operator to easily enable and modify machine features.
• Operation ControlCat: The 100% pilot controls provide excellent machine control with fine modulation, eliminating the need for linkage and cable maintenance, reducing ownership and operating costs, and resulting in less downtime.

Structural Design

• Stability: The standard tail – swing and fixed – boom design ensure the maximum stability, reach, and lift capacity of the excavator, making it perform stably during operation.
• Durability: The heavy – duty structural design ensures the durability and reliability of the machine. The undercarriage and key components are made of high – quality materials, which can withstand the harsh working environment and long – term heavy – load operation.

Application Scenarios

• This excavator is widely used in municipal engineering, such as pipeline laying and road repair; small – scale construction, such as foundation excavation and backfilling; agricultural applications, such as farmland consolidation and water conservancy construction; garden landscape projects, such as terrain shaping and greening construction; and industrial maintenance, such as factory area renovation and equipment installation.
