5.5 ton mini crawler excavator

Shengkunda provides the High-performance new and used 5.5 ton mini crawler excavator as a versatile solution for modern small-scale construction and municipal projects. The 5.5 Ton Mini Crawler Excavator Xe55da with Yanmar Engine or equivalent high-torque diesel units offers a maximum digging depth of 3.5–4m and a bucket capacity of 0.2–0.25m³. As a highly maneuverable Crawler Excavator 5.5 Ton Mini Digger with Hydraulic Pipeline, it allows for the seamless attachment of breakers or grabs. The precision hydraulic system ensures a response time of ≤0.5s, providing smooth control over the digging arm and slewing mechanism while maintaining low ground pressure (≤30kPa) to protect sensitive surfaces.

Product Features

● Compact and Low-Impact Design
The streamlined body allows for easy passage through garden paths and residential alleys. Lightweight rubber tracks distribute weight evenly, preventing damage to floor tiles, lawns, or soft terrain during indoor or landscape operations.

● High-Efficiency Hydraulic System
The 5.5 ton mini crawler excavator delivers a working pressure of 20–25MPa. This enables a digging efficiency of 8–10 m³/h, allowing operators to complete trenching, loading, and backfilling tasks with minimal fuel consumption and maximum precision.

● Durable Wear-Resistant Components
The bucket teeth are manufactured from high-hardness steel (HRC 50-55) to resist impact and abrasion. All critical joints utilize sealed structures and high-elasticity fluororubber seals to prevent oil leakage and protect against dust intrusion.

● User-Centric Operator Environment
The excavator is configured with an adjustable seat, clear instrument panels, and a dust-proof cab option. Simple joystick controls reduce operator fatigue during long shifts, making the machine accessible for both professionals and beginners.

Application Scenarios

1. Residential and Indoor Renovation
This 5.5 ton mini crawler excavator is ideal for digging foundation pits for home extensions, breaking indoor floors with silent breakers, or backfilling pipe trenches in confined residential quarters where space is limited.

2. Garden and Landscape Construction
The flexible crawler chassis allows for precise terrain leveling, pond excavation, and large tree transplantation. Its specialized attachments make it highly effective for detailed shaping without damaging existing paved roads.

3. Municipal and Farmland Operations
The 5.5 ton mini crawler excavator is perfectly suited for excavating gas, water, or cable trenches and cleaning irrigation ditches. In agricultural settings, it efficiently handles livestock pen cleaning and small-scale land transformation.

Manufacturing and Refurbishment Details

New Unit Precision Manufacturing
Our new production line utilizes high-grade raw materials, including corrosion-resistant aluminum for hydraulic tanks. We maintain strict dimensional tolerances, such as a digging arm lifting angle error of ≤1° and crawler wheel spacing tolerance of ≤±2mm.

Professional Used Unit Maintenance
Used units are sourced exclusively from projects with short service lives. Our Jinan center performs targeted repairs, replacing aging filters and seals with parts that meet or exceed original factory specifications to eliminate abnormal noise and leaks.

Advanced Testing Equipment
We utilize hydraulic system pressure testers and engine performance benches to verify output stability of our 5.5 ton mini crawler excavator. Structural flaw detectors are used to inspect the digging arm and chassis for cracks or deformation, ensuring total structural safety.

Quality Assurance

- Double-Round Functional Testing
Every 5.5 ton mini crawler excavator undergoes two rounds of simulated working condition tests (digging, lifting, and walking) before delivery. We verify that slewing speeds reach 8-10 r/min and walking straightness deviation remains ≤50m/100m.

- Technician Certification
All maintenance and inspections are carried out by certified technicians who follow a standardized evaluation process. This ensures that even used machines reach a performance level nearly equivalent to new units.

- Comprehensive Component Verification
For every 5.5 ton mini crawler excavator, we verify that the wear on bucket teeth is ≤3mm and the hydraulic oil is free of contamination. This 100% inspection protocol guarantees that the machine is ready for immediate deployment upon arrival.
