Longgong 855B Rock King Loader 1000-Hour User Report - MikePhua - 06-27-2025
I purchased the Longgong 855B loader in late November 2009, and after more than six months of use, I’ve accumulated just over 1000 operating hours. Below is a summary of my experience with this machine, including both its advantages and disadvantages.
Advantages
- Sturdy and Durable Build
As part of the Rock King series, this loader has a solid, heavy feel that instills confidence in its durability. It's designed to handle tough work environments effectively.
- Minimal Rear Lifting During Digging
The machine rarely exhibits rear lifting when scooping material, thanks to a well-designed counterweight in the rear that helps maintain balance during operations.
- Excellent Visibility
The loader is equipped with a panoramic glass cabin, which offers excellent visibility. This feature significantly improves the operator's awareness of their surroundings, contributing to better safety and control during work.
- Poor Interior Quality and Sealing
The interior finishes of the cabin are subpar, and the sealing performance is inadequate. After only a few dozen operating hours, screws on the dashboard loosened and could not be tightened again. Additionally, both doors do not close tightly, and there is a rattling sound when they are shut.
- Poorly Designed Bucket Guard Plate
The guard plate on the bucket is poorly designed. The cutting edge of the bucket is exposed by only about 10 centimeters, which affects the digging feel. After a few hours of use, I removed the guard plate and plan to weld a new one later.
- Heavy Control Levers
The control levers are a bit stiff, which can be tiring for the operator over long shifts. I’ve tested several Longgong loaders, and this seems to be a common issue across their models.
- Difficult Engine Compartment Access
The rear hood of the engine opens upward, making it inconvenient for routine maintenance and servicing. This design could have been more user-friendly.
Around 500 operating hours, the steering cylinder's oil inlet hose joint began to leak slightly. By 800 hours, the multi-way valve also started to leak oil. Fortunately, these issues were resolved with help from the after-sales service team.
At just over 900 hours, I noticed a leak in the transmission oil pressure gauge. The after-sales service informed me that the instrument was considered an electrical component, and the warranty only lasted for 3 months. I ended up purchasing a replacement pressure gauge for 45 yuan and swapped it myself.
Conclusion
Overall, the Longgong 855B Rock King loader has performed well during its first 1000 hours of operation, with a few minor issues related to its interior quality and maintenance accessibility. However, these problems haven’t significantly impacted its overall performance. The loader is sturdy, reliable, and well-suited for tough tasks, although there’s room for improvement in the design of certain components.
