Detailed Introduction of CATERPILLAR 307.5 Compact Excavator

The Caterpillar 307.5 is a 7-ton class next-generation compact excavator developed by Caterpillar Inc., the global leading construction equipment manufacturer. Positioned as a high-versatility, low-operation-cost small excavation solution, it is widely favored by small construction contractors, equipment rental operators, and individual owners, suitable for both urban narrow-space operations and outdoor non-road working scenarios.

1. Core Performance

Power System

It is equipped with a Cat C2.4 turbocharged 4-cylinder diesel engine that meets global strict emission standards (Tier 4 Final / EU Stage V / China National IV Emission Regulation), with a net rated power of 43kW (57hp) at 2200rpm. The engine adopts high-efficiency fuel filtration and combustion optimization technology, adapts to low-quality fuel in underdeveloped regions, and has strong high-altitude and high-temperature operation stability.

Hydraulic & Operation Performance

It is matched with Caterpillar’s mature load-sensing hydraulic system, with a total system flow of 148L/min, realizing smooth compound action of boom, stick and bucket, and micro-operation accuracy as high as ±10mm. Standard configurable boom offset function supports left and right swing of the working arm, which can realize excavation operation close to the wall, extremely suitable for narrow sites such as old city reconstruction and indoor demolition.Key operation parameters:

Operating weight: 7400~7800kg
Max. digging depth: 4080mm (13ft 5in)
Max. dumping height: 5140mm (16ft 10in)
Bucket capacity range: 0.22~0.38m³
Travel speed (2 gear): 2.6km/h (low) / 4.8km/h (high)
Optional integrated dozer blade supports site leveling and improves operation stability.

2. Operator Comfort & Safety

The pressurized sealed cab reduces dust intrusion and operation noise, with an internal sound pressure level as low as 72dB(A).

Equipped with fully adjustable suspension seat, high-cooling/heating efficiency air conditioning system, USB charging port and large storage space, reducing fatigue of long-time operation.
The high-definition LCD monitor displays real-time operation parameters, fault alarm and maintenance reminder in real time. Optional rear view camera eliminates blind spots of reversing.
The cab is ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure) certified, fully protecting the safety of operators under high-risk working conditions.

3. Durability & Reliability

All core structural parts (boom, stick, chassis frame) are made of high-strength wear-resistant steel, and all welding joints have passed 1000-hour extreme working condition fatigue tests.
The undercarriage adopts sealed and lubricated track chain, heavy-duty support rollers and idlers, with a service life 20% longer than that of previous generation models.
The hydraulic system adopts 3-micron high-precision filtration, which extends the hydraulic oil change cycle to 5000 hours, greatly reducing maintenance costs.
All electrical connectors are waterproof and corrosion-resistant, adapting to rainy, snowy and high-salt coastal working environments.

4. Serviceability & Intelligent Functions

All daily maintenance points (air filter, fuel filter, oil filter, hydraulic oil filling port) are designed to be accessible from the ground, no need to climb on the top of the machine, shortening maintenance time by 30%.
Standard equipped with Caterpillar exclusive Product Link™ remote monitoring system, which supports remote viewing of equipment location, fuel consumption, operation hours and fault warning, helping managers improve fleet operation efficiency.
Caterpillar’s global dealer network provides 24/7 after-sales service and genuine spare parts supply, reducing unexpected downtime.

5. Application Scenarios

The 307.5 excavator supports fast replacement of multiple attachments (breaker, auger, grapple, ripper, etc.) via optional quick coupler, and is suitable for:

Municipal engineering: trench excavation, pipeline laying, sidewalk maintenance
Landscape construction: tree pit digging, site leveling, landscape shaping
Civil construction: foundation excavation, material handling, small building demolition
Agricultural operation: farmland reconstruction, irrigation ditch digging, farm waste cleaning
Narrow-space operation: indoor demolition, factory interior renovation, underground garage construction
