Caterpillar 955L Crawler Loader: A Comprehensive Overview
#1
Introduction
The Caterpillar 955L crawler loader, introduced in the late 1970s, stands as a testament to Caterpillar's commitment to engineering durable and versatile heavy machinery. Designed to meet the demands of construction, forestry, and agricultural industries, the 955L combines the functionality of a bulldozer and a wheel loader, offering operators a multifaceted tool for various tasks.

Specifications
  • Engine: The 955L is powered by the Caterpillar D330 four-cylinder turbocharged diesel engine, delivering approximately 130 horsepower. This engine provides the necessary power for demanding tasks while maintaining fuel efficiency.
  • Operating Weight: Approximately 34,950 lbs (15,860 kg), making it a robust machine capable of handling substantial workloads.
  • Dimensions:
    • Length with bucket on ground: 16.25 ft (4,950 mm)
    • Width to outside of tracks: 7.09 ft (2,160 mm)
    • Height to top of cab: 7.52 ft (2,290 mm)
    • Ground clearance: 1.37 ft (416 mm)
    • Reach at full dump height: 3.84 ft (1,170 mm)
  • Undercarriage:
    • Track width: 14.97 in (380 mm)
    • Track gauge: 66.15 in (1,680 mm)
    • Number of track rollers per side: 6
    • Ground contact area: 2,759.01 in² (1.78 m²)
  • Hydraulic System:
    • Hydraulic raise time: 6.6 seconds
    • Dump time: 1.6 seconds
    • Lower time: 3.2 seconds
  • Bucket Capacity:
    • Struck: 1.7 yd³ (1.3 m³)
    • Heaped: 2.1 yd³ (1.6 m³)
  • Performance:
    • Static tipping load: 18,607 lbs (8,440 kg)
    • Breakout force (standard bucket): 22,930 lbs (102 kN)
    • Maximum speed: 7.1 mph (11.3 km/h)

User Experiences and Insights
Owners and operators of the 955L have shared a wealth of practical knowledge regarding its performance and maintenance:
  • Final Drive Issues: A common concern involves the final drive assembly. Users have reported instances where bolts securing the final drive case have broken, leading to potential damage. Regular inspection and maintenance of these components are crucial to prevent such failures.
  • Track Repairs: The 955L utilizes a bolt-together track system. In cases where a track link is damaged, replacing the individual link is possible. However, removing and replacing track pins can be challenging due to their press-fit design. Some operators have resorted to heating the pins to facilitate removal, though this method requires caution to avoid damaging seals.
  • Hydraulic System Maintenance: The hydraulic system, while efficient, demands regular maintenance. Operators have noted that the hydraulic raise time and dump time are relatively swift, but ensuring the system's longevity requires attention to fluid levels and filter conditions.

Comparative Analysis
When compared to its contemporaries, the 955L holds its ground:
  • Versatility: Unlike dedicated bulldozers or wheel loaders, the 955L's combined functionalities make it adaptable to a wide range of tasks, from digging and lifting to pushing and grading.
  • Durability: The robust construction of the 955L ensures longevity, provided it receives regular maintenance and care.
  • Operator Comfort: While not equipped with modern amenities, the 955L's cab design offers adequate protection and visibility for operators.

Conclusion
The Caterpillar 955L crawler loader remains a valuable asset in various industries due to its versatility, durability, and performance. Understanding its specifications, user experiences, and maintenance requirements ensures that operators can maximize its potential and longevity. Whether you're considering acquiring a 955L or currently operating one, this comprehensive overview serves as a valuable resource for informed decision-making and effective machine management.
