Used Japan Original Komatsu PC50MR-2 PC55MR PC55 PC50 Excavator 5 Ton Hydraulic Crawler Backhoe Excavator Cheap for Sale

Komatsu 50 excavator is a multifunctional equipment suitable for small projects:

1. Basic parameters

Power system

Engine: Equipped with Komatsu 4TNV88 inline four-cylinder engine, power range 32.4-50 kW (43.5-50 hp), displacement 2.19 liters, supports low fuel consumption and low temperature start design.

Hydraulic system: hydraulic flow 145 liters/minute, working pressure 22-32.4 MPa (different configurations), providing efficient operation response.

Weight and size

Machine weight: about 4.9-5 tons (4900-5000 kg), crawler width 400 mm, compact body (total length 4990 mm, total width 1700 mm), suitable for narrow space operations.

Travel speed: 2.2-4.8 km/h, rotation speed 0-10.5 rpm, maximum climbing gradient 30°, adapt to complex terrain.

Digging performance

Bucket capacity: 0.13-0.3 cubic meters (standard bucket 0.16 cubic meters), supports multiple options such as ditch cleaning bucket and bucket.

Maximum digging depth: 3-3.87 meters, maximum digging height 5.5 meters, digging force 36 kN, suitable for small earthwork projects.

2. Performance characteristics

Structural design

The boom and dipper are reinforced, and the bucket is made of wear-resistant materials to improve durability.

Low ground pressure design (about 34.1 kPa) reduces pressure loss on soft ground.

Operation and maintenance

The cab layout is simple, with optional LCD monitor for easy operation; equipped with heating and cooling air conditioning to improve comfort.

Fully open hood design for easy daily maintenance; centralized lubrication system reduces maintenance complexity.

Economy

The fuel tank capacity is 80 liters, the hydraulic oil tank is 57-60 liters, supporting continuous operation; low fuel consumption design and automatic idling function optimize the use cost.

3. Applicable scenarios

Municipal engineering: The compact size is suitable for narrow space operations such as urban pipeline laying and greening maintenance.

Agriculture and land leveling: small and medium-sized earthwork handling, ditch excavation and orchard preparation.

Mining auxiliary operations: light ore excavation and material handling, but pay attention to its tonnage limit.
