Product Details

This 2021 Caterpillar 336 used excavator retains its original factory-applied paint with uniform gloss and zero corrosion, confirming careful storage and minimal wear. Its heavy-duty undercarriage features 33-inch triple grouser track shoes, showing only 20% wear with intact bushings and sprockets for superior stability on rugged terrain. Ideal for mining and construction, this machine combines aesthetic integrity with proven durability. Includes global shipping and inspection report.

Powered by the original Cat C7.1 engine, this 2021 model delivers 223.5 kW (300 HP) with Tier 4 Final compliance for global emissions standards. Advanced fuel injection cuts consumption by 9%, while robust cooling ensures durability in extreme conditions. With only low operating hours, it maintains peak performance for mining and heavy construction. Ideal for buyers seeking OEM-powered efficiency and long-term reliability.

The 2021 Cat 336 features a heavy-duty mining undercarriage with reinforced track chains and rollers, designed for 5,000+ hours in abrasive environments. Its DuraLink technology provides 20-40% longer wear life than standard systems, while sealed components resist dust and rock damage. Ideal for hard rock excavation, this OEM chassis ensures stability and low cost-per-hour performance.

Frequently Asked Questions

1. Why do some used excavators need repainting?
A: Repainting a used excavator generally occurs in the following situations:
1. Exterior aging due to extended use
2. Exterior damage caused by special operating conditions such as mines and tunnels
3. Equipment that has been in an accident and requires repair
(Painting is primarily for protection and visual enhancement and does not necessarily indicate a condition problem.)

2. How can I determine the true year of production of the excavator?
A: Every excavator has multiple stamps (Vehicle Identification Number, Parts Number, Year of Production, etc.). Common locations include: cab, glass, fuel tank, engine, boom, arm, swing motor, etc. Typically, there are more than ten stamps that can be cross-checked to avoid misrepresenting the year of production.

3. How can I identify the model of the excavator?
A: The model number is generally composed of numbers and letters:
The number represents the tonnage, such as "200" for approximately 20 tons. Letters:
H: Reinforced/Heavy Duty (with enhanced protective gear);
L: Longer (longer chassis with one or two additional road wheels);
LC: Longer and Wider (suitable for wetland operations, with increased load-bearing capacity);
W: Wheeled Equipment.

IV. How to Assess the Value of Used Excavator?
A: Consider the following key factors:
1. Age: Identify the year by the stamped number and accessories.
2. Operating Condition: Has it been used under high-intensity conditions such as mines and tunnels for extended periods?
3. Wear of Key Components: The performance of core components such as the engine, hydraulic pump, and motor.
4. Appearance and Maintenance: Check for signs of accidents and timely maintenance.
5. Maintenance: Check for proper maintenance procedures and smooth operation.

V. Is Painted Excavator Always Not Worth Buying?
A: Not.
Refurbishing equipment due to appearance aging or minor damage will not affect core performance. However, caution is advised if the paint is applied to conceal signs of an accident or serious damage. It's recommended to make a comprehensive assessment based on the stamp number, maintenance records, and performance testing.

VI. What should you pay attention to when purchasing a used device?
A: 1. Don't just look at the appearance; pay attention to the operating condition of the device's core components.
2. Carefully verify the stamp number to avoid product substitution or misrepresentation of the year.
3. Observe for obvious welding or splicing marks.
4. Verify that the device has been thoroughly conditioned, preferably with a test report.
