Scraper
Minca4AJ is a mine explosion-proof shovel developed on the basis of the introduction of the German PAUS company "PFL18S" type scraper technology. The Minca 4AJ scraper has achieved three "domestic firsts": 1, the largest power 2, the lightest weight, and the smallest shape.
Main feature:
1. Strong power, the maximum breakout force can reach 6 tons.
2. Able to walk freely in narrow lanes.
A 1.7-meter-wide roadway can be passed in a straight line; it only takes a 3-meter-wide roadway to turn a 90-degree right-angle bend.
3. Working equipment:
Equipped with various working mechanisms such as buckets, forks, booms, etc., it can be quickly replaced to meet the needs of various underground work, and other working mechanisms can be installed according to customer needs.
4. Cab:
The ROPS/FOPS cab provides comprehensive protection for the driver.
The detachable driver roof is convenient for underground transportation.
5. Maintenance: The whole vehicle adopts centralized lubrication, which is convenient for maintenance.
6. The core components are all famous foreign brands, and the quality is stable and reliable.
