2010-2023 VOLVO 4400 UNDERGROUND WHEEL LOADER

Technical Description

The Volvo 4400 Underground is a compact articulated wheel loader engineered for underground mining and confined space operations. Powered by a turbocharged TD 60 B diesel engine, this machine delivers 143 gross horsepower (107 kW) at 2,100 rpm, providing adequate power for underground hauling applications. The loader features a 3.1 cubic yard heaped bucket capacity, optimized for efficient material handling in restricted environments. With an operating weight of 26,124.8 pounds (11,850 kg) and static tipping weight of 18,959.8 pounds (8,600 kg), the 4400 Underground maintains a compact profile suitable for underground mine workings. The machine rides on 20.5-25/16-L3 tires, designed for traction and durability in challenging subsurface conditions. Built during the 1978-1987 production era, this loader incorporates a power shift transmission, rugged planetary hub axles, and a dual brake system with disc brakes and front axle differential lock. The pressurized, ROPS-approved cab provides operator protection with integrated heating and air conditioning, while the parallel linkage arm system delivers high breakout force and excellent material handling control. Its articulated design enables superior maneuverability in tight underground spaces, making it an effective solution for underground mining operations where conventional wheel loaders cannot operate effectively.
