FKWJ-4 Underground Diesel Loader

The Scooptram FKWJ-4 is a reliable 8 ton capacity underground loader that delivers unrivaled productivity in tough underground conditions. The FKWJ-4 Underground Loader is designed for high production, low cost tonnage and tamping in underground mining applications. An operator favorite, it provides a safe, comfortable ride in the cab with easy-to-use controls and efficiency-enhancing features that optimize performance and maximize productivity. Its compact design provides flexible performance combined with robust construction and simplified maintenance to ensure excellent productivity, long life and low operating costs.

FKWJ-4 Underground Loader Specific Description

FKWJ-4 underground diesel loader fuel efficient  engine delivers powerful thrust for fast bucket filling and high speed tramming for high productivity. The engine for unrivaled traction when digging, pedaling and traversing steep grades. Optional engines comply with EU Stage III and US EPA Tier 3 standards. Optional Reduced Ventilation (VR) package, which combines selective engine hardware and software to reduce diesel particulate matter in engine exhaust and provide significant ventilation rate reductions, lower fuel consumption, and maintain or enhance product performance . Torque rises to effectively match transmission shift points for maximum efficiency and fast cycle times. Four sizes of dump buckets provide unmatched productivity and structural reliability, featuring two types of cast corners to help strengthen the side plate-lip engagement and allow for a variety of cutting edges. The frame is designed to withstand the extreme forces generated during loading and pedaling cycles, with deep penetration and consistent welds that ensure a solid fusion of the structure, providing a solid platform for the linkage and axle.

To make your job easier, we offer digital add-ons ranging from diagnostics and remote control to fully autonomous operation.


1.Ergonomic canopy and side seats provide good two-way view operation.

2.Enhanced boom and load frame geometry optimize digging performance
